The price of gas may go up or down, but it's always a major expense for most drivers. The average American driver spends about $3,000 per year on gas, according to the American Automobile Association. Some of the practical ways to reduce fuel costs are listed below.

Use public transportation

Walking or biking does not consume fuel, and as such does not accumulate fuel cost. In most cases, public transport alternatives to cars such as buses, trains, and trolleys are viable options of reducing fuel costs. Due to the communal nature of ride sharing, the fuel costs of operating public transport are generally less than the fuel costs associated with each individual operating their own vehicle. In some places, public transport is free. Considering the costs associated with owning or renting a car creates even more incentive to use other modes of transportation.

Also known as car sharing, carpooling is the arrangement between two or more people to travel to a shared destination in a single vehicle. Although a heavier car consumes slightly more fuel, it is usually much more efficient than two people driving separate cars towards the same destination.

Use a more fuel efficient vehicle

Driving a smaller car makes a great difference – the fuel cost is about half for a small sedan than for a very large SUV. Similarly, drive with a less powerful engine than you need. Don't pay for an eight-cylinder engine when four cylinders work just fine. Unless you're hauling heavy loads on a routine basis, the extra cost of a bigger engine results in more money spent on gasoline.

Tune the engine

A properly tuned engine maximizes power and can greatly enhance fuel efficiency. But tuning the car engine is often done to increase horsepower – that's not the way to save on fuel. Make sure the tuner gets the message.

Fixing a car that is noticeably out of tune or has failed an emissions test can improve its gas mileage by an average of 4 percent – this amount will vary depending on the nature of the repair.

Fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve your mileage by as much as 40 percent.

Placing ornaments and ground effects, aerodynamics kits, and airfoils, such as deck-lid spoilers, may make you feel good, but they also increase the car's drag and make it require more fuel. Such accessories offer no real handling enhancements, although they may look nice on your car. Also, place signs or cargo on the roof so that the object angles forward. This will reduce the frontal area of the object, and it will cause less drag, and cause you to use less fuel.

Adjust tires

Make sure the tires are inflated to the right levels. Properly inflated tires can reduce fuel consumption by up to 3 percent. Your tires also lose about 1 PSI per month, and when the tires are cold (e.g., in the winter), their pressure will decrease due to the thermal contraction of the air. It is recommended to check tires at least monthly, preferably weekly. Having properly inflated tires will also help you avoid uneven wear on the tread.

Gas stations don't always have accurate equipment for this purpose. Sometimes gas stations use automatic air compressors that stop at a pre-determined level. To make sure you inflate to the right level, double-check pressure with your own gauge.

Recommended inflation pressures are for cold tires; put about 3 PSI more in if the tires have been driven on a while. Inflate to the pressure recommended by the car manufacturer, not to the level stamped on the tire.

Use the correct motor oil

Gas mileage will improve by 1 percent to 2 percent if you use the manufacturer's recommended grade of motor oil. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can reduce your gas mileage by a considerable amount. Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1 percent to 2 percent. Also, look for motor oil that says "Energy Conserving" on the API performance symbol to be sure it contains friction-reducing additives.

Plan trips carefully

There is no more obvious way to save gas than to drive a shorter distance.

Plan your route carefully. With today's GPS route planners, it's easy to calculate a straight route with the fewest stops and diversions. It is also possible to judge which route will have the least traffic. Take highways instead of local routes or city streets when possible – the steady speed maximizes fuel efficiency.

When driving in a city, try to park in a central location, and then walk from one appointment to another, or take public transportation. Ragged stop-and-go city driving is terrible for your gas mileage. This also saves the high level of gas used in parking and pulling out in a parking lot.

Factors that determine the fuel price

Government intervention.

Governments may intervene in gasoline (referred to as petrol in some parts of the world) markets by taxation, which may raise prices for consumers within or outside the governmental territory. Similarly, certain industries may receive financial support from the government to promote commercial enterprise (a subsidy). Generally, subsidized products or services can be sold at lower prices.

Financial markets

The global oil price fluctuates constantly. The key crudes quoted are Brent and West Texas Intermediate (WTI) in the unit of US$ per barrel. The retail fuel price is closely related to the global oil price fluctuation.

Political elements such as structure, regime, personnel, and events can all affect the cost of fuel. For instance, a change in leadership from a leader who doesn't believe in climate change to one who does may result in changes to the cost of fuel for consumers based on different policies, such as choosing not to subsidize fuel. Political relationships between countries are also a factor; nations can go to war over resources, or form alliances in order to trade, both of which can affect the cost of fuel.

Geographic area

Certain geographical areas or countries in the world have an abundance of oil, while others do not have a single drop. Regional consumers within close proximity of high supplies of oil are more likely to have lower costs of fuel due to ease of access. Areas without their own supply of oil that are isolated from the rest of the world (such as islands in the Pacific) can find fuel to be relatively expensive.

Natural disaster or weather

Earthquakes, tsunamis, hurricanes, major floods, and other such nature-related phenomena can affect the production, manufacturing, and logistics of gasoline, which can possibly affect the price of fuel. For instance, a snowstorm may close certain roads, disallowing the transportation of the resource and driving up fuel costs in these areas. Hurricanes or earthquakes can damage oil refineries, abruptly halting production, which can also eventually increase fuel costs.

    Fuel Needed & Fuel Cost Calculations

In order to calculate the amount of fuel for a given trip using our fuel cost calculator or otherwise, you need to know the total distance you will be covering and the expected average fuel consumption of your vehicle. It works the same way for cars, trucks, buses, vans, SUVs, and even boats and planes. If you also want to calculate the fuel cost of a trip, then you need to know the price per gallon or price per liter at which you can by.

Our calculator supports entering distances in miles and kilometers. In terms of fuel consumption, it is very versatile as it accepts: miles per gallon, gallons per 100 miles, kilometers per liter and liters per 100 kilometers. In the US, miles per gallon and kilometers per liter would more frequently used, while in most of Europe the preferred metric would be liters to travel 100 km and gallons to cover 100 miles. The result in terms of fuel amount is in gallons or liters, and for fuel cost is in the currency you entered it in (you can simply ignore the currency sign, e.g. $ (USD)).

Make sure to account for the variation in fuel consumption when driving within city limits and on highways - usually the consumption is higher in the former case. Always fill your tank with more fuel than you anticipate you would need, especially during winter or when driving through desolate areas or when extreme weather conditions are expected.

    Formula for fuel amount

If you are using mpg (miles per gallon), then the formula for calculating the total amount of gas needed is:

Fuel = Distance / Consumption mpg

For example, if the distance is 500 miles and consumption is 20 miles per gallon, then the fuel you will need for the entire distance is 500 / 20 = 25 gallons.

If you are using gallons per 100 mi to measure consumption, then the formula for calculating the amount of fuel needed is:

Fuel = Distance / 100 x Consumption per 100 mi

For example, if the distance is 300 miles and the consumption is 5 gallons per 100 miles, you will need 300 / 100 x 5 = 15 gallons of gas.

Both formulas are applicable for metric units - km and liters, just make sure you do not mix metric units. Using an online fuel calculator will make sure you do not commit that mistake.

    How to improve fuel economy?

Don't like the numbers you see when you use our tool? If you wonder how you can improve the fuel efficiency of your vehicle so you can cover more miles (or kilometers) with less fuel, we have some tips that can result in significant savings, especially when applied consistently over time. Here is our list of 10 fuel efficiency tips :

• Drive sensibly - If you drive aggressively - too fast compared to other cars, constantly overtaking other vehicles, and rapid acceleration followed by braking, only to accelerate again wastes a lot of gas. By some estimates, quick starts and hard stops can increase fuel consumption by more than 30% ! This is why this is number one in our fuel efficiency list.
• Observe the speed limit - Different vehicles have optimal fuel economy at different velocities, but one way to increase gas mileage is to avoid driving at higher speeds. A small reduction of your average speed , say from 70 mph to 60 mph (equivalently: from 115 km/h to 100 km/h) can help you save 10 to 20% due to lower fuel consumption.
• Follow the leader - drive at about the speed of the vehicle in front of you, if they are following the first 2 tips above. This will make sure you need to accelerate and decelerate as little as possible. If possible, overtake drivers who do not follow them, as it will make it very hard for you to do so. This will result in smaller numbers from our fuel cost calculator.
• Check your tires - make sure your tire pressure is at optimal levels as indicated in the owner's manual provided by the auto manufacturer. If the pressure is too low your mileage will decrease significantly, not to mention that the car may become dangerous to drive.
• Smart routing - make sure you take optimal paths to reach your desired destination. Learn the different modes of route selection your GPS employs - the shortest is not always the fastest and idling stuck in traffic will waste fuel. Use services such as Google Maps to check for traffic congestions on the planned route. Using a route you know well can also help improve fuel efficiency, since you will know in advance where it makes sense to increase speed and where it does not, because of a traffic light just ahead.
• Air conditioning - turning it off will most likely improve your fuel efficiency by 10-15%, and will result in you having more power to accelerate quicker when needed. If it is necessary, make sure you do not set it to unreasonably low or high levels. Air temperature in the range between 64°F - 75°F (18°C - 24°C) is comfortable for most people. Due to the law of thermodynamics, each subsequent degree of heating or cooling requires progressively more energy to accomplish and maintain.
• Remove excess weight - make sure you remove any unneeded heavy items you have in your trunk. One of the untold benefits of losing weight is that your car will be a bit more efficient as well.
• Turn cruise control ON - when on a highway, make sure to use your cruise control option. By keeping your speed constant, it will most likely save gas and result in lower fuel costs.
• Avoid idling - idling means 0 miles per gallon and the larger the car engine, the more gas is wasted when idling. Avoid excessive idling, when possible, in line with point #5 above to keep fuel costs low.
• Maintain your vehicle - a well-maintained car, truck, van, SUV, etc. will operate at greater efficiency. Exact fuel savings are hard to calculate, as it will depend on the type of maintenance work your vehicle needs. However, good maintenance is sure to lead to fuel savings and smaller cost numbers coming out of our calculator.

All the above advice is fine, but what do you do if you have been following the above advice, yet our tool still shows you numbers that are so high you want to cry? Well, it is most likely time for a new car, or it could be just the fuel price fluctuations over which, unfortunately, neither you nor we have much influence, individually. Fuel prices in most places contain license fees and other state or local government taxes, in some places reaching as much as 50% of the final price. Financial market fluctuations, natural disasters or extreme weather, crisis, as well the geographical area you are in and the local fuel suppliers all influence the price of gas. All you can do is try to observe them and predict when you can get a more decent price.

Why you should know how much fuel you will need and the cost before buying gas for your trip

With the price of gas going up daily and your buying power steadily declining due to inflation, the unfortunate truth is that it is unwise to plan a road trip without first calculating the cost of gas. After all, gas is not the only thing you will need.

Before you plan your trip, you need to recognize that there can be lots of unexpected expenses when you are away from home. As such careful planning and a detailed budget are most important for a worry-free trip. You can typically expect to spend money on:

• Entertainment;
• Emergency repairs;
• Emergency medical care.

Process used by our fuel cost calculator to find how much gas you will need as well as the cost of your trip

To calculate how much fuel you will need, here is the formula used by our fuel cost calculator:

Fuel amount= Distance / Fuel efficiency

For instance, if you wish to travel 100 km with a vehicle with a fuel efficiency of 5 kilometers per liter , substitute these variables into the formula above:

Fuel amount= 100 / 5 = 20 liters

Our calculator also uses the amount of fuel and the cost of gas in your area to calculate the total cost of your trip. For this, we use the following formula:

Trip cost = Fuel amount × Fuel price

So using the amount of fuel given in the above problem, if the price of gas was $7 , then to calculate the amount of money needed for the trip, we put these values into the formula, and we get:

Trip cost = 20 × 7 = $140

What is the best way to take a road trip on a small budget?

If you are planning a road trip for your vacation, but your budget is relatively small, here are a few things you can do:

• Go during the offseason. Vacation rentals cost less in the offseason. This price reduction is because the demand for these places is relatively low during the off-season. So owners and agents reduce the price to attract more visitors.
• Take a road trip with others willing to share the cost. Sharing the cost will reduce your individual payment. For instance, if the fuel price for the trip is $1000, you will pay less by splitting that cost five ways between friends. You can do this using our gas cost calculator .
• Try camping to reduce the cost of accommodation. Campsites cost less than the average hotel.
• Research fun, entertaining activities that you and your friends can do free of cost or for a small fee. For example, use a map to explore with your team rather than hiring a tour guide.
• Pack food that you can quickly fix on the go rather than eating in restaurants. The cost of food can eat into your vacation money. As such, finding ways to eat for less can make the difference in the amount and type of activities you will be able to engage in.

Is it cheaper to drive or fly for long distances?

Due to the additional costs for items such as food and accommodation for several days, a road trip across great distances can cost significantly higher for long-distance trips than flying. This can, of course, be affected by these factors:

• Number of persons on the trip;
• Whether the cost is shared or not; and
• Type of accommodation used.

How do I calculate fuel cost?

To calculate the fuel cost, we use one of the following formulas:

• Fuel cost = (Distance / Efficiency per gallon) × Cost per gallon
• Fuel cost = (Distance / [100 × Consumption per 100 mi]) × Cost per gallon

Use the first formula if you have the car's efficiency in miles per gallon (mpg).

On the other hand, we use the second formula if the consumption is in gallons per 100 miles.

How do I calculate fuel cost per month?

To find the fuel cost per month:

• Multiply the distance per day by the number of days per month.
• Divide this by your vehicle’s efficiency per gallon.
• Multiply the answer by the price per gallon.

How much does a gallon of gas weigh?

A gallon of gasoline weighs approximately 6.073 lbs in the US.

Gasoline contains additives that affect its final weight. These vary from country to country. As such, it is impossible to give an exact weight worldwide.

Trip Gas Price Calculator

About trip gas price calculator (formula).

The Trip Gas Price Calculator is a tool used to estimate the total cost of fuel for a trip based on the distance traveled, vehicle’s fuel efficiency, and current gas price per gallon or liter. It aids in budgeting and planning for travel expenses. The formula for calculating the trip gas price involves considering the distance, fuel efficiency, and gas price.

Formula for calculating trip gas price:

Trip Gas Price = (Distance / Fuel Efficiency) * Gas Price

In this formula, “Distance” represents the total distance to be traveled in miles or kilometers, “Fuel Efficiency” represents the vehicle’s fuel efficiency in miles per gallon (MPG) or kilometers per liter (KPL), and “Gas Price” represents the cost of gas per gallon or liter.

For example, let’s say the total distance of the trip is 300 miles, the vehicle’s fuel efficiency is 30 MPG, and the gas price is $3.50 per gallon. The trip gas price would be calculated as follows:

Trip Gas Price = (300 miles / 30 MPG) * $3.50 per gallon = 10 gallons * $3.50 per gallon = $35.00

This means that the total cost of fuel for the 300-mile trip would be $35.00.

The Trip Gas Price Calculator simplifies the process of estimating fuel expenses for a trip, aiding travelers in budgeting and planning for their journeys. By inputting the distance, fuel efficiency, and gas price, the calculator quickly provides the trip gas price, allowing travelers to have a clear view of their fuel costs and make informed decisions to manage travel expenses effectively.

Fuel Cost Calculator

Fuel Cost Calculator is a tool to estimate gas costs for your trip. The gas cost calculator is calculated based on the distance in miles or km, miles per gallon, and the gas price per gallon.

Gas Mileage Calculator

The gas mileage calculator is useful for anyone who wants to calculate the costs of driving from one city to another. If you are planning a route trip and is price conscious, then gas costs is definitely something you may want to take into account. The distance, the mileage, and the total fuel costs can add burden to your budget especially if you are travelling long distance. With the rise in gas prices, the cost on fuel can get out of control quickly if you don't plan carefully. At fuel cost calculator, you can use our free gas estimator to help you estimate the total costs on gas and plan accordingly.

How the fuel cost calculator works?

The fuel cost calculator uses the trip distance, miles per gallon, and the current gas price to calculate the total cost when you travel from one location to another. 1. Trip Distance - the distance in miles or kilometers between the two locations. 2. Miles Per Gallon - the number of miles or kilometers that you can travel with 1 gallon of gas. You will travel fewer mileages per gallon when travelling locally, and many more mileages when you are on a highway. The miles per gallon is the average miles that you can travel with one gallon of gas. 3. Gas Price - the current gas price per gallon. With only these 3 inputs, the gas cost calculator will calculate the total costs for you.

How to save money on fuel cost?

There are many ways to save on fuel cost when you are travelling locally and sometimes in long distance. 1. Public Transportation - can sometimes save you money than driving. With driving, you may have to pay toll and stuck in traffic during rush hours. You may also need to pay for parking fees at your destination. With public transportation such as subway, you can often get away with traffic and can do activies that you like during commute such as reading or playing with your phone. If you are someone who does not enjoy driving, taking public transportation may not be a bad option. 2. Carpool - if public transportation is not an option. You can carpool with a coworker if you are driving to work. Carpool allows both of you to save money and having someone to keep you company while driving so you don't get bored. 3. Electric Car - you can also get an electric vehicle like a Tesla to save money on gas costs. With a gas car, you may spend more money on gas than the electricity cost of an electric car. It may be most costly upfront to buy an electric car, but it may save you money in the long run if you are using your car on a daily basis or travelling a lot.

How to Calculate the Cost of Fuel

To estimate the amount of fuel used for a trip and to find the cost of that fuel, follow these simple steps.

Start by estimating the driving distance for the trip. Try Google Maps to find your trip distance.

Then, find the estimated EPA fuel efficiency of your vehicle. This will let you know how approximately many miles per gallon (MPG) you can expect from it during your trip.

This information can be found in the owner’s manual or online. [1] You will see MPG ratings for city, highway, and combined city and highway driving – use the MPG rating that comes closest to the type of driving that you will be doing on the trip.

Next, check the price per gallon of the gasoline that you are using, which will be needed to calculate the cost of the trip.

Finally, enter those values into these formulas to calculate the amount of fuel used and to determine the cost of that fuel:

fuel used = distance ÷ fuel efficiency fuel cost = fuel used × cost per gallon

Be sure that your fuel economy units are the same as the units of fuel being purchased (MPG and gallons of fuel). For metric fuel consumption, try our liters per 100 km to km per liter conversion calculator to find the fuel economy value to use in these formulas.

For example , let’s find the cost of a 200-mile trip in a vehicle that gets 22 mpg with a fuel cost of $2.85 per gallon.

Start by finding the amount of fuel used:

fuel used = 200 ÷ 22 fuel used = 9.09 gallons

Then, calculate the cost of the fuel used:

fuel cost = 9.09 × $2.85 fuel cost = $25.91

Thus, you can expect to use 9.09 gallons of gasoline for this trip, which will cost you $25.91.

A gas mileage calculator provides information specific to your vehicle’s fuel performance based on the data you input. The information output — like miles per gallon (mpg) or annual fuel cost — can help you plan and make decisions in different ways.

When you have an estimate of your annual fuel costs, you can build that into your weekly or monthly budget.

If your car’s actual mpg is lower than expected, it might indicate a mechanical problem that needs correcting to reduce gas consumption.

If you’re thinking of buying a different car, a gas calculator can compare expected gas expenses for other cars with what you’re currently spending.

NerdWallet’s gas calculator is a simple-to-use tool broken into two parts: step one calculates your car’s mpg and step two shows your annual fuel expenses compared to another vehicle's estimated mpg.

How to use the gas mileage calculator

To make using the gas calculator easier, gather and document information ahead of time. For step one, you’ll need to input the following:

Note your car's odometer reading after you fill up the gas tank, then note the odometer reading the next time you fill up. These odometer readings are used to determine how many miles you got on one full gas tank, so you'll want to make sure your tank is as empty as possible before the second fill-up.

How many gallons of gas you needed to fill your tank the second time.

You may want to complete these steps several times to get an average mpg, since your driving habits can change between fill-ups. For example, you might do more highway driving during one cycle, which consumes less gas than city driving.

For step two, you will need the following:

The average price you pay for a gallon of gasoline. You can also find average gas prices on NerdWallet’s website.

An estimate of the number of miles you drive each year. According to the U.S. Department of Transportation's Federal Highway Administration (FHWA), the average person drives about 13,500 miles per year. 

If you want to compare your current car’s fuel costs with another vehicle, you’ll need the other car’s estimated mpg. You can find this estimate for most vehicles at fueleconomy.gov .

Use the gas mileage calculator and comparison tool to run scenarios with different inputs. You can see how changing factors — like gas prices and number of miles driven — affect your vehicle’s fuel economy and you may uncover ways to save money on gas .

How to improve your vehicle’s fuel efficiency and save money on fuel

With fuel prices on the rise, it is becoming increasingly important to find ways to improve your vehicle’s fuel efficiency.

Whether you have a car or van, there are several small adjustments that you can make that will help to reduce your fuel usage and save you money over time.

1. Check your tyre pressure regularly

Having the right tire pressure is essential for getting the most out of your fuel economy.

Underinflated tires cause more drag and decrease how efficiently your car runs. Make sure to check your tire pressure regularly and top them up as needed.

2. Reduce unnecessary weight in your car

It may not seem like much, but those extra few pounds can add up quickly when it comes to reducing your mileage.

Remove any unnecessary items from the boot of your car, such as sports equipment or heavy tools that you don’t use often. Every little bit helps.

3. Change your oil regularly

When oil gets too dirty, it can reduce engine performance and lead to decreased fuel efficiency. It is recommended that you get an oil change every 3-5 months (depending on the type of oil used) so that your engine stays clean and operates at its optimum level of performance.

4. Use cruise control whenever possible

Cruise control helps maintain consistent speeds which translates into improved mileage since you don’t have sudden starts and stops or fluctuating speeds while driving.

So if you are going on a long drive or even to another town, cruise control can be a great way to save some money on fuel.

5. Drive at steady speeds

Driving at steady speeds helps conserve fuel because when you accelerate quickly it uses up more fuel than when acceleration occurs slowly over time. Try driving at a steady speed whenever possible in order to maximize fuel efficiency.

6. Take care of your engine

Taking care of your engine is one of the best ways to ensure maximum fuel efficiency for your vehicle. Change air filters regularly and make sure all fluids are topped off so that it runs smoothly and efficiently.

7. Avoid idling

Idling your vehicle for extended periods of time wastes a lot of fuel and can significantly reduce fuel efficiency. Whenever possible, try to turn off the engine when you’re stopped instead of letting it idle.

8 . Avoid high speeds

Driving at higher speeds can decrease your fuel efficiency significantly. Whenever possible, try to keep your speed below the posted speed limit in order to maximize fuel efficiency.

9. Use eco mode

Most modern cars come with an eco mode, which you can use to help reduce fuel consumption and get better mileage.

This mode helps reduce engine power and alters your transmission shift points in order to conserve fuel.

10. Drive smarter

Last but not least, smart driving is the best way to reduce fuel usage and save money in the long run.

Smart driving techniques include accelerating slowly, avoiding sudden braking and idling, using cruise control, and following the speed limit.

By driving more efficiently you can reduce your overall fuel costs while also being kinder to the environment.

The Simple Formula For Calculating How Much Gas Will Cost On Your Road Trip

T he idea of hitting the open road and enjoying an adventure without daily responsibilities included can be endlessly exciting. Yes, a road trip enjoyed alongside family and friends can feel liberating, but when it comes to your travel budget, the story might be a little more restrictive. Somehow, road trips have a way of adding up to totals beyond what travelers initially anticipate.

Between the cost of lodging, food, and the souvenir shopping to be done along the way too, things can understandably get pricey. It's not uncommon for it all to be more than you bargained for. One of the big hitters when it comes to your road trip budget is typically the amount you'll spend on gas.

Fluctuating gas prices from city to city and between states only add to the confusion. This makes having a plan in place before you get behind the wheel a good idea. While you can't control the price of gas, you can closely calculate what you'll spend by using a simple four-step process.

If you plan in advance, there's room to focus on the road trip fun ahead once you set off. You'll have a budget you can work with that won't cause added stress too. To calculate how much gas will ultimately cost on your road trip, you'll need to look at the gas mileage on your vehicle, how far you're traveling, and the gallons of gas required.

Start With Vehicle Fuel Efficiency And Miles You'll Travel

The first step in calculating how much gas will cost on your road trip is determining how many gallons of gas per mile your vehicle uses. Start by looking up your vehicle's fuel tank capacity which is found in the owner's manual. From here, it's easy to reset your trip odometer, fill up your tank and take note of how far you've gone when it's time to refill again.

It's important to remember that how you drive can make a difference in how your vehicle burns fuel during a road trip. City driving comes with a lot of stop-and-go traffic which uses more gas more quickly. Extended stretches of highway and interstate driving can make gas go farther.

When figuring out the gallons per mile on your vehicle, make sure to use the driving techniques you're likely to use on your road trip for a more accurate picture of gas mileage. If you have multiple vehicles, it's worth your while to test them all. The more fuel-efficient model is going to save you money in the long run.

Step two is to take a look at the total distance you anticipate you'll be traveling. Modern apps like Google Maps make this a fairly quick and easy task. While you might not know exactly what all of your side stops will be, consider adding in a few you think you'll be making to get a more accurate mile count.

Gallons Of Gas Give You The Cost You've Been Looking For

The third step in this calculation is to note current gas prices. This is going to fluctuate everywhere you travel, but using the national average is a useful point of reference for this cost equation. AAA has an easy-to-view national gas price log that adjusts daily. The U.S. Department of Energy also provides a gas price map where costs can be broken down by state and city.

The final step in calculating your road trip gas costs involves some easy math. Begin by dividing your total trip miles by your vehicle's miles per gallon. The answer is the total gallons of gas your journey is going to require.

Multiplying the total gallons of gas needed by the national gas price average will result in an accurate estimate of what you'll spend on gas during your trip. Having this number available will help you budget more efficiently. It will also give you the freedom to worry less about overspending along the way.

You can't control or even plan out every little detail of a trip . You most likely wouldn't want to anyway when unexpected adventures are often half the fun of a road trip. However, the cost of gas isn't something you have to leave to chance when you have this handy calculation available. Put it to use and feel free to let the exploring officially begin.
