EV Calculator
Eight free, data-driven calculators covering every cost question about owning an electric vehicle — from cost per mile by ZIP code to payback period vs gas.
EV Cost Per Mile →
Most popularPick any EV + ZIP code → instant cost per mile across home flat rate, TOU off-peak/on-peak, DC fast, and gas equivalent.
Total Cost of Ownership →
NewFull 5- or 10-year cost: purchase, financing, insurance, maintenance, depreciation, and charging vs a gas car.
EV vs Gas & Payback →
Fuel savings, CO₂ avoided, and the payback period on the EV's price premium — in one tool.
Real-World Range →
NewWhat range you'll actually get at your speed, temperature, terrain, and load — not the EPA lab number.
Charging Time →
How long to charge any EV at Level 1, Level 2, or DC fast — with battery taper modeled in.
Used EV Battery Health →
Estimate battery degradation and remaining range on a used EV, with a 3-year forward projection.
Road Trip Planner →
Real driving routes with charging stops, total time, and cost vs gas for any EV.
Compare Two EVs →
Side-by-side spec, range, charging speed, efficiency, and cost-per-mile comparison.
How our EV calculators differ
- • Real utility rates — flat and time-of-use tariffs sourced from OpenEI for every U.S. utility, not a national average.
- • Real gas prices — U.S. EIA weekly retail gasoline by state, refreshed automatically.
- • Real EV specs — fueleconomy.gov + manufacturer data for usable battery, mi/kWh, and DC peak.
- • DC fast tiers — member vs guest pricing for the dominant networks (Tesla, Electrify America, EVgo, ChargePoint).
