EV Charging Cost Per Month by Model
Enter the miles you drive and how much of your charging happens at home, pick your state, and see the kWh and the dollars per month, with your overnight rate if you have one.
EV charging cost
F02Scenario A
Sets the electricity rate. Pick US average if you're not sure.
From EIA for US average. Use the rate on your bill if you know it.
Rate used: 18.4¢/kWh · US average · EIA reference 2025–26 · gasoline $3.20/gal (data as of 2026-09-26) ·

Formula
How it works
- kWh per month from the outlet = kWh per 100 miles ÷ 100 × miles per month × 1.12 × home share
- Home charging cost per month = kWh × electricity rate
- With the overnight rate = kWh × the rate you entered
- Gas-car equivalent = miles per month ÷ 30 mpg × gasoline price (all miles, for comparison)
The 1.12 adds about 12% for charging losses between the wall and the battery.
Sources: EPA fueleconomy.gov combined kWh/100 mi for each model. About 85% of EV charging happens at home (DOE). Charging losses ~12% (DOE / Idaho National Laboratory). Electricity rate: EIA Electric Power Monthly table 5.6.A; gasoline price by state: EIA and AAA.
Worked example
A worked example
A Rivian R1S uses 49 kWh per 100 miles. Driving 1,200 miles a month and charging 80% of it at home in California takes about 527 kWh a month from the outlet. At California's average rate of 32.0¢/kWh that's $168.59 a month; on a 24¢ overnight rate it's $126.44. A 30 mpg gas car covering the same 1,200 miles would use an estimated $188.00 of gasoline.

Questions
FAQ
How much does it cost to charge a Model Y per month?
At the US average rate of 18.4¢/kWh, a Tesla Model Y Long Range driven 1,000 miles a month with 85% of the charging at home uses about 267 kWh and costs an estimated $49.05 a month. A 30 mpg gas car would use about $106.67 of gasoline for the same miles.
Does charging to 100% cost more?
Each kWh costs the same. Charging to 100% puts more kWh in the battery, so that session costs more, but the cost per mile doesn't change. How full to charge day to day is a battery-care question: follow your car's manual.
Level 1 vs Level 2: which costs less?
They put the same kWh in the battery; Level 1 (a regular outlet) usually loses a little more on the way. This calculator uses the same 12% loss for both. The difference that matters is time: see the charge time calculator.
What if I charge at work or on the road?
Lower the home share. The home cost drops, and the rest is whatever those chargers charge you.
Why is the gas equivalent for all my miles?
Because a gas car would drive all of them on gasoline. It's there to show the scale of the fuel cost you replace; it isn't a saving the calculator promises.
