Fuel Cost Calculator
Estimate the fuel cost of a trip from distance and economy.
Budget any drive
Before a long drive it helps to know what the fuel will cost. It comes from three numbers: how far you are going, how many miles per gallon your car does, and the price of fuel.
A 200-mile trip in a 25 MPG car at 3.50 a gallon costs about 28 in fuel. Enter your own figures to budget a journey or compare the cost of two routes.
Practical and private
The calculation runs in your browser, so nothing you enter is uploaded.
