Fuel cost calculator. Price the trip before you run it.
Enter your trip miles, MPG and diesel price to see what a trip and a month of trips will cost in fuel, and what one more mile per gallon is worth.
The same trip at different MPG
Every mile per gallon changes what the trip costs. Your truck is in the middle.
Bar and bold figure are per trip. Lighter figure is per month.
These results are estimates for planning. They are not a loan offer, a quote or financial advice. Your actual rate, payment and costs depend on your lender, your truck and how you run it.
How it’s worked out
Gallons are your trip miles divided by your MPG.
Monthly cost is the trip cost multiplied by the number of trips.
One more MPG runs the same trip at your MPG plus one, and shows the difference.
| 1,200 miles ÷ 6.5 MPG | 184.6 gal |
|---|---|
| Times $3.90 a gallon | $720.00 |
| Times 4 trips a month | $2,880.00 |
| One more MPG saves, per month | $384.00 |
Fuel cost questions
How do I work out my real MPG?
Fill the tank, write down the odometer, run until your next fill, then divide the miles you drove by the gallons you put in. Do it over a few fills for a truer number.
Why is one more MPG worth so much?
Every gallon you do not burn is money kept, and on a truck that runs a lot of miles those gallons add up fast. The fewer MPG you get now, the more one extra is worth.
Does this include DEF or fuel surcharges?
No. It counts diesel only. If you want those in your total, build them into the price per gallon or into your cost per mile.
Are the numbers filled in real diesel prices?
No. They are examples so you can see how the calculator works. Use the price you actually pay.
Can I use this to compare two trucks?
Yes. Run it once with each truck’s MPG and compare the monthly cost. That difference is part of what a better-running truck is worth to you.
