What this site does
FuelPriceCalculator.com answers one question: what will the fuel cost? The fuel cost calculator handles a single drive, and the other calculators cover road trips, a yearly fuel budget, how far your gas money goes, the cost of a commute, what a price change does to your bill, and the same math in kilometers and liters.
Fuel economy itself, meaning MPG ratings, vehicle lookups and comparisons, lives on the sister site, GasMileageCalculators.com. Keeping the two subjects apart lets each site do its one job well.
How the numbers are checked
Every calculator uses the standard fuel cost formula, distance ÷ fuel economy × price, with exact conversion factors for kilometers, US gallons and UK gallons. Each one is tested against hand-worked examples before it goes live, and the worked example on each page is one of those checks.
The "Pick your car" box reads the U.S. EPA fuel economy ratings published on fueleconomy.gov. The lookup files are generated straight from the EPA's vehicle file rather than typed in by hand, and they're rebuilt whenever the EPA posts an update. CO2 figures use the EPA's published grams of CO2 per gallon of gasoline and diesel.
The site doesn't publish gas prices. Every dollar figure comes from the price you enter, or is clearly marked as an example. If you spot a number that looks wrong, let us know and it will be checked and corrected.
