Fuel Cost Calculator
Estimate gasoline cost for a trip using distance, MPG, and gas price.
Estimate the fuel cost of a road trip, commute, delivery route, or vacation. Use your expected driving distance, vehicle fuel economy, and local gas price.
Fuel-cost formula
Gallons needed equal miles divided by miles per gallon. Multiply the gallons by the price per gallon to estimate fuel cost.
Real-world MPG can vary
Speed, traffic, weather, tire pressure, terrain, towing, idling, and vehicle load can all change actual fuel economy.
Round-trip planning
If you entered one-way distance, remember to double it for a round trip unless your route calculator already shows the full route.
Frequently asked questions
Can I use highway MPG?Yes, if most of the trip is highway driving. A combined MPG estimate may be better for mixed routes.
Does it include tolls or parking?No. Add those separately to get total trip cost.
