Step 1: Enter your numbers

These inputs match the homepage calculator, but focus on the EV vs gas comparison. For full home/public mix and state defaults, use the main calculator.

Electricity price ($/kWh)

Use your all-in rate from your bill (energy + delivery + fees).

EV efficiency (Wh/mile)

Try 280–320 for many EVs. Use your car’s average for accuracy.

Charging loss (%)

Accounts for inefficiency from heat and overhead.

Miles per month

Used for monthly totals and break-even.

Gas price ($/gal)

MPG (comparable gas car)

Home charger + install cost (optional)

Enter your out-of-pocket cost after rebates (or enter rebates below).

Common reasons your results differ from your bill

All-in electricity rate: many bills include delivery, riders, and taxes that raise the true $/kWh.
Seasonal pricing: winter/summer rates can change the average.
Time-of-use plans: off-peak charging can cut cost dramatically.
Fast charging: public DC fast charging is usually the priciest $/kWh.
