About Fuel Consumption Calculator

What this site does

Every calculator and reference page here answers one practical question: what will this actually cost in fuel? That includes a general trip fuel cost calculator, a page for each of 30 tracked vehicles with official EPA fuel economy and annual cost figures, gas prices for 29 US regions, driving cost for 30 directional city-to-city routes, 15 side-by-side vehicle comparisons, and a cost-per-mile comparator for weighing a gas vehicle against an electric one.

There is no account to create and nothing to pay for. Every calculator runs entirely with the numbers you enter; nothing you type into a calculator is sent anywhere or stored.

Where the data comes from

Vehicle fuel economy, annual cost estimates, and CO2 emissions figures come from official EPA data published at FuelEconomy.gov, for the specific trim and model year listed on each vehicle page. Gas and diesel prices come from the U.S. Energy Information Administration's weekly retail fuel survey. Driving distance and time for each route come from OpenStreetMap Nominatim geocoding and OSRM routing, not a straight-line estimate.

This is an independent site. It is not affiliated with, endorsed by, or sponsored by FuelEconomy.gov, the U.S. Environmental Protection Agency, the U.S. Energy Information Administration, or any vehicle manufacturer named on this site.

How the pages are built

Every vehicle, route, region, and comparison page is generated from the same underlying dataset the calculators use, rather than written one by one. That keeps the numbers consistent across a vehicle's own page, its appearance in a comparison, and its appearance in a route's cost-by-vehicle-type breakdown.

Every figure is an estimate, not a guarantee of what you will personally pay. See the EPA testing guide for why real-world fuel economy commonly differs from a lab rating, and each page's own "last updated" date for how current its figures are.
