Fuel Cost Calculator

Estimate fuel cost for any trip: distance, vehicle MPG and gas price. See the cost per mile and total for the round trip.

About this tool

This fuel cost calculator estimates how much a road trip will cost: enter the total distance, your vehicle's miles per gallon and the current gas price, and it returns gallons needed, total fuel cost, round-trip cost and cost per mile.

Budget trips before you drive, compare two cars for the same route, or share gas money fairly with co-drivers — the per-mile figure makes comparisons across vehicles immediate.

FAQ

How do I calculate fuel cost?

Gallons = distance / MPG, then multiply by the gas price per gallon. This calculator does both steps and the per-mile cost.

What is a typical car MPG?

Modern sedans average 28–40 MPG, SUVs 22–30 MPG and pickup trucks 15–22 MPG. Your dashboard shows your real average.

How accurate is the trip cost?

Very close for highway driving. City traffic, stop-and-go or AC use can raise it by 10–20%.
