Cost to Charge a Tesla Calculator: Home Charging Cost by State
Charging a Tesla at home is almost always far cheaper than fueling a gas car — but exactly how cheap depends on your battery size, how many miles you drive, and your local electricity rate. A typical Tesla holds around 75 kWh of usable capacity and travels roughly 250 miles on a full charge, so a complete home charge costs about what your utility charges for 75 kWh. This calculator shows the cost to fully charge, the cost per mile, and your monthly charging cost at your state's electricity rate.

How we calculate this →How Tesla home charging cost is calculated
The calculation starts with your battery capacity in kWh and your state's residential electricity rate. A full charge cost is simply battery × rate: a 75 kWh Tesla at $0.17/kWh costs $12.75 per complete charge. Cost per mile follows from dividing the full charge cost by range — a 250-mile range makes each mile cost about 5.1 cents, before any charging losses.
Monthly cost scales with how many miles you actually drive. If you cover 1,000 miles a month, you need 1,000 ÷ 250 = 4 full-equivalent charges per month, using about 300 kWh. At the U.S. average rate that adds roughly $51 to your electricity bill.
A real Level 2 home charger (typically 7.2–11.5 kW) loses about 8–12% to heat during charging, so the wall-to-battery efficiency means you'll pull slightly more kWh from the wall than the battery actually stores. This calculator uses the usable battery kWh as the baseline, which slightly understates actual electricity consumption — for a precise bill estimate, add 10% to the monthly kWh figure. Many utilities also offer overnight EV time-of-use rates well below the residential average, which can cut monthly charging cost by 20–40%.
