EV Charging Cost Calculator
What it really costs to charge — your state, your car: full-charge price, cost per mile, fast-charging comparison and gas savings.
Using Texas's average residential rate (15.6¢/kWh) · national average 16.9¢ · includes ~10% AC charging losses. Rates vary by utility and plan — your bill is the source of truth.

Frequently asked questions
How much does it cost to fully charge an EV at home?+
At the national average residential rate (16.9¢/kWh), a typical 75 kWh EV costs about $14 to fully charge at home — roughly 4-5¢ per mile. State rates range from ~11¢ (North Dakota, Idaho) to 42¢ (Hawaii), so the same charge runs $9 to $35 depending on where you live.
Is charging an EV cheaper than gas?+
Almost always at home: 4-5¢ per mile versus about 10¢ per mile for a 32-mpg gas car at $3.15/gallon — typically $50-70 saved per 1,000 miles. Public DC fast charging (~43¢/kWh) narrows the gap to near parity, which is why home charging drives EV economics.
Why is public fast charging so much more expensive?+
You're paying for the hardware and the speed: DC fast chargers cost six figures to install, draw commercial-rate power with demand charges, and sit on real estate. The ~43¢/kWh average is 2-3× home rates — fine for road trips, expensive as a daily habit.
Do these numbers include charging losses?+
Yes — home (AC) charging figures include roughly 10% conversion losses, which most calculators quietly skip. The kWh your battery stores is less than the kWh your meter bills.
