At 300 kWh/month, 16¢ home vs 45¢ public saves about $87/month — over $1,000 a year.

Home charging is the EV's real fuel discount

An EV charged at home on a 16¢/kWh residential rate “fuels” at the equivalent of roughly $1.40/gallon of gas. The same EV on 45¢ public fast charging pays the equivalent of about $4.00/gallon. The car didn't change — the plug did.

When public charging makes sense anyway

Road trips, apartments without home charging, and free workplace charging all break the simple comparison. If you can't charge at home, compare public rates against gas directly in the gas vs EV calculator instead of assuming the home-charging discount.

Time-of-use rates sweeten it further

Many utilities offer overnight EV rates of 8–12¢/kWh. If yours does, rerun with that rate — the savings column gets dramatically bigger.

Frequently asked questions

Is home EV charging cheaper than public?

Almost always — home rates of 12–20¢/kWh vs public fast charging at 35–60¢/kWh means home charging typically costs one-half to one-third as much.

How much can I save charging an EV at home?

At 300 kWh/month, 16¢ home vs 45¢ public saves about $87/month or $1,044/year.

How many kWh does an EV use per month?

A typical driver (1,000 miles/month at ~3.4 mi/kWh) uses about 300 kWh. Check your car's efficiency screen for your number.

Is public charging cheaper than gas?

Often roughly comparable per mile — public charging's per-mile cost lands near an efficient gas car. Home charging is where EVs win big.
