About EVCalc & our method

EVCalc is a free, no-sign-up calculator that answers one question: how much would I spend fueling an electric car compared with a gas car where I live? Everything runs in your browser.

The formulas

• EV energy: miles per year × kWh per 100 miles ÷ 100.
• Charging price: a blend of your home rate and a public fast-charging rate, weighted by the charging-mix slider (default 85% home, fast charging $0.45/kWh).
• Gas cost: miles per year ÷ MPG × price per gallon.
• Savings: gas cost − charging cost + (gas upkeep − EV upkeep). 5-year figures are 5 × the yearly number, with no inflation.
• Payback: the extra price of the EV ÷ yearly savings.

Price presets

State electricity presets are rounded residential averages based on U.S. Energy Information Administration (EIA) state data. Gas presets are rounded statewide averages for regular gasoline. The national defaults are 16¢ per kWh and $3.50 per gallon. Prices move every month, so every field is editable — your own bill and pump price always beat an average. Presets were last reviewed on 2026-11-10.

Vehicle presets

Efficiency presets are rounded, EPA-style combined ratings for common versions of each model. Trim, wheels, weather and speed change real-world results. Choose Custom to type your own car's rating from fueleconomy.gov or your window sticker. Model names are used for identification only; we are not affiliated with any automaker.

Metric view

The Metric switch converts distance to kilometers, efficiency to kWh/100 km and km/L, and money to Korean won using an exchange rate you can edit (default ₩1,400 per $1).

What we don't include
