EV Calculator
Seven 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.
EV vs Gas Savings →
5-year fuel cost comparison and CO₂ avoided for any EV vs a comparable gasoline car.
Breakeven Calculator →
How many miles until EV savings pay back the price premium over an equivalent gas car.
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).
