Assumptions used
- 15,000 mi a year (≈ 24,140 km). The EPA combined rating already blends 55% city and 45% highway driving.
- Regular gasoline: $4.36/gal (U.S. average, EIA, Sep 2026).
- Per-year costs are rounded to the nearest $10 (under $100: the nearest $1). Monthly, per-100-miles and per-mile figures are calculated from the rounded yearly cost.
- Real costs vary with driving style, weather, tires and how much of your charging happens at home.
What this calculator shows
It estimates what one version of a U.S. car costs to fuel over a year: gasoline, diesel, electricity, or both for a plug-in hybrid. It covers every model year from 2000 on, using official EPA ratings and dated EIA prices for the state you pick. For a vehicle EPA does not rate, such as a heavy-duty pickup, switch to your own MPG and type the average you measured.
Everything on the page, including the numbers shown before you change anything, comes from the same formulas and data as the car pages, so the results here match them.
How the cost is calculated
Gas, diesel and hybrid: miles per year ÷ combined MPG × price per gallon of the fuel the car needs. Premium cars use the premium price and diesel cars the diesel price. EPA's unrounded rating is used when it is published.
Electric: miles per year × kWh per 100 miles ÷ 100 × price per kWh. EPA's kWh figure already counts charging losses at the wall.
Plug-in hybrid: EPA's utility factor says what share of miles is driven on electricity. That share is priced at the electricity rate and the rest at the gasoline rate, using the car's gasoline MPG.
Assumptions
- 15,000 miles a year unless you change it, with EPA's mix of 55% city and 45% highway driving (already inside the combined rating).
- Gasoline and diesel use EIA monthly retail prices: the state's own series where EIA publishes one (nine states), otherwise its region's. Alaska and Hawaii have none, so you type a price.
- Electricity uses EIA's residential price for the state, which approximates charging at home.
- Costs are rounded to the nearest $10. Taxes, tolls, maintenance and insurance are not included, and prices are held flat for the year.
- Hydrogen and natural gas vehicles are not costed because there is no reliable official price series for them.

Frequently asked questions
How is the yearly fuel cost worked out?
Divide your yearly miles by the car's MPG to get gallons, then multiply by the price per gallon. For an electric car, multiply miles by its kWh per 100 miles, divide by 100, and multiply by the price per kWh. Plug-in hybrids mix the two using EPA's utility factor.
Why does this differ from the cost on EPA's label?
EPA's published annual fuel cost uses one set of national prices and rounds to the nearest $50. This calculator uses the same method with dated EIA prices for your state and rounds to the nearest $10, so it moves when your local prices move.
How do I use my own gas or electricity price?
Type it into the price field. It replaces the looked-up price for whatever fuel the car uses. Leave the field empty to use the EIA price. Alaska and Hawaii need a typed gas price because EIA publishes none for them.
Why does the list show several versions of one model?
EPA rates every engine, drive and transmission combination separately, and a model year can include gas, hybrid and electric versions. Pick the one that matches the car you are looking at; the list is grouped by powertrain.
Will I get the EPA rating in real driving?
Not exactly. EPA ratings come from standardized tests so cars can be compared. Speed, weather, load, tires and driving style move real results up or down, so treat the number as a fair comparison between cars rather than a promise.
