EV Charging Cost Calculator 2026: Home Cost per Month
Calculate your 2026 EV home charging cost per month, per year and per mile, and compare home electricity rates with public DC fast charging prices.

How to use this calculator
- Enter your EV battery size in kWh (find it in your vehicle's specs).
- Enter how many full charges you do per week on average (two half charges = one full charge).
- Enter your home electricity rate in $/kWh. The US residential average is $0.182/kWh (EIA, July 2026 year-to-date); use your off-peak EV rate if you have one.
- Enter your EV's efficiency in miles per kWh.
- Read your monthly cost, annual cost, cost per full charge and cost per mile.
Understanding your results
Short answer: At the US average of $0.182/kWh (EIA, July 2026 year-to-date), home charging costs about 5.2¢ per mile in an EV that gets 3.5 mi/kWh, or about $52 for 1,000 miles. There is no federal EV purchase credit in 2026, so the operating savings are the main financial case for an EV.
How home charging cost is calculated: Monthly cost = battery size × full charges per week × 4.33 weeks × electricity rate. With the default inputs (75 kWh, 2 charges per week, $0.182/kWh): 75 × 2 × 4.33 = 650 kWh, × $0.182/kWh = about $118 per month. That powers roughly 2,273 miles (650 kWh × 3.5 mi/kWh). A 30 mpg gas car driving the same distance at $3.25 per gallon uses about $246 of fuel, so the EV saves roughly $128 a month in this example.
Cost per mile is the most useful metric: Cost per mile = electricity rate ÷ efficiency. At $3.25 per gallon and 30 mpg, gasoline costs about 10.8¢ per mile. Home charging at $0.182/kWh and 3.5 mi/kWh costs about 5.2¢ per mile. In Hawaii (46.28¢/kWh, the highest state average in our EIA data) home charging costs about 13.2¢ per mile. In North Dakota (12.36¢/kWh, the lowest) it is about 3.5¢ per mile.
Time-of-use rates can lower your cost: Many utilities offer time-of-use or EV rates with cheaper overnight electricity. Scheduling charging for off-peak hours lowers your cost in direct proportion to the rate difference; enter your off-peak rate above to see it.
Public charging comparison: DC fast charging prices vary widely by network and state; at the $0.35/kWh used in our calculators (an editorial assumption), public charging costs about 1.9 times the average home rate. With 80% home and 20% public charging, the blended cost at 3.5 mi/kWh is about 6.2¢ per mile. Drivers who rely mostly on fast charging give up much of the fuel-cost advantage over gasoline.
2026 incentive status: The federal §30D and §25E EV credits ended for vehicles acquired after September 30, 2025, and the §30C charger credit ended for chargers placed in service after June 30, 2026. State and utility programs vary; check your state energy office or utility. This is not tax advice; confirm with a tax professional.
