Road Trip Fuel Calculator – Calculate Fuel Costs

Planning a road trip is an exciting adventure that allows you to visit new places, see beautiful scenery and travel your own pace. Estimating how much fuel you will need and how much money you will spend is an important element of any road trip.

A Road Trip Fuel Calculator will allow you to easily estimate how much fuel you will need for your journey. Simply input how far you will be travelling, how many miles per gallon your car does and the price of fuel.

Depending on what vehicle you are using for your road trip, the fuel cost will vary. If you have a fuel efficient Sedan it could be much cheaper than using a large SUV or Pickup.

In the United States, vehicles will typically be measured against how many miles they can do per gallon (MPG), how many miles you will be traveling and price of fuel in USD per gallon. This will make it easier for you to estimate how much fuel you will need to budget for.

Whether you are going on a short weekend break, family holiday or long distance road trip, the Road Trip Fuel Calculator will help you plan and compare the different options to ensure you are not caught out by any unexpected fuel costs.

How to Use the Road Trip Fuel Calculator

The Road Trip Fuel Calculator is very easy to use. All you need to do is input some basic information about your vehicle.

1. Input the Total Distance

Enter how many miles you will be travelling. If you wish to calculate the fuel cost for your return journey then be sure to include this.

2. Input the Fuel Economy

Enter the average MPG your vehicle does. This information can typically be found in your vehicles handbook or manufacturers specs.

3. Input the Fuel Price

Enter the current price of fuel per gallon in your area. If you will be purchasing fuel at various points then you can input the average fuel price along your route.

4. Choose if one-way or round-trip

If available select if you are doing a one-way or round-trip.

5. Add Extra Miles

If you are stopping to see sights, getting lost or stopping for meals then be sure to add extra miles.

6. Calculate Fuel Cost

Click calculate to give you an estimate of how much fuel you will need and how much money you will spend.

7. View Results

This will show you how many gallons of fuel you will need and how much money you will need to budget.

For more accurate results, use the average MPG of your vehicle.

Road Trip Fuel Calculator Formula

The Road Trip Fuel Calculator uses the following simple formula.

1. Fuel Needed

Fuel Needed (Gallons) = Total Distance (Miles) / Fuel Economy (MPG)

2. Total Fuel Cost

Total Fuel Cost = Fuel Needed (Gallons) x Fuel Price Per Gallon

3. Round-trip Distance

Round-trip Distance = One-way Distance x 2

4. Fuel Cost per Mile

Fuel Cost per Mile = Fuel Price Per Gallon / Vehicle MPG

Example

Let’s say you are going on a road trip from Los Angeles, California to Las Vegas, Nevada and back.

Your estimated trip details would be:

Detail Value

One-way Distance 270 Miles

Round-trip Distance 540 Miles

Fuel Economy 30 MPG

Fuel Price $4.00 per Gallon

1. Calculate Total Fuel Needed

Fuel Needed = 540 / 30

Fuel Needed = 18 Gallons

2. Calculate Total Fuel Cost

Total Fuel Cost = 18 x $4.00

Total Fuel Cost = $72

3. Calculate Fuel Cost per Mile

Fuel Cost per Mile = $4.00 / 30

Fuel Cost per Mile = $0.133

You can now see that you will be spending around $72 on fuel for your 540 mile round-trip. You will also need around 18 gallons of fuel.

If you are travelling with 3 other people and you will be splitting the cost of the fuel then:

Cost per person = $72 / 4

Cost per person = $18

As shown in this example, using a Road Trip Gas Calculator will help you estimate how much you will be spending on fuel.

The actual amount of fuel you will spend could vary based on the road conditions, how you drive and the fuel price.

Understanding Your Results

Once you have input your trip details you will be given an estimate of how much fuel you will need and how much you will spend.

Below are the different results and what they mean:

1. Total Distance

This will show you how many miles you will be travelling. If you are calculating a round-trip, be sure to include both ways.

2. Estimated Fuel Needed

This will show you how much fuel (in gallons) you will need to complete your journey based on your vehicle’s MPG.

3. Estimated Fuel Cost

This will show you how much money you will need to spend on fuel.

4. Fuel Cost per Mile

This will show you how much you will be spending on fuel per mile travelled. This can help to see which vehicles are most fuel efficient.

5. Cost per Person

If you are travelling with friends or family and you are splitting the cost of the fuel then this will show you how much each person should be contributing.

These results are an estimate of how much you will be spending on fuel. They won’t include any other costs such as tolls, accommodation, food and parking.

Factors Affecting Road Trip Fuel Cost

There are several factors that could affect how much fuel you will need.

1. Distance Traveled

The longer your journey the more fuel you will need. Small changes to your route can affect how much fuel you use.

2. Vehicle Fuel Economy

The higher the MPG of your vehicle the less fuel you will need to complete the same journey. Hybrid vehicles and fuel efficient sedans could be cheaper to run than large SUVs and pickups.

3. Fuel Price

Fuel prices can vary between states, cities and individual fuel stations. Prices can vary based on supply and demand, seasonal trends and tax.

4. Speed

Driving at high speeds can decrease your fuel economy. Try to drive at a steady and reasonable speed.

5. Traffic

Driving in heavy traffic, frequently stopping and sitting in traffic can increase your fuel usage. Driving in urban areas may increase the amount of fuel needed.

6. Load

Having heavy luggage, camping equipment, bikes and extra passengers can affect your fuel economy.

7. Weather & Road Conditions

Driving in strong winds, extreme temperatures, rain, snow, steep hills and rough roads can increase fuel usage.

8. Driving Style

Aggressive driving, speeding up quickly, sudden stops and excessive idling can decrease your fuel economy. Drive smoothly to help improve your mileage.
