How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

Fuel needed = Distance ÷ MPG. Trip cost = Fuel needed × Gas price. This calculator helps plan road trips and estimate travel expenses.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.

Frequently asked questions

How do I find my car's MPG?

Fill up the tank, reset the trip odometer, drive normally, then fill up again. Divide miles driven by gallons added. Or check your car's onboard computer or EPA label.
