How home charging cost is calculated
Home charging cost comes from two numbers: the price you pay for electricity, in cents per kWh, and how much energy the car uses to travel a set distance, in kWh per 100 miles. Multiplying the two gives a cost per 100 miles, which is the figure in the table above. It uses a 30 kWh-per-100-miles efficiency assumption and each state's residential electricity rate; a more efficient car lowers the per-mile cost, and a higher local rate raises it.
Cost per 100 miles is the fair way to compare an EV with a gasoline car because it puts both on the same distance basis. Cents per kWh and dollars per gallon are not directly comparable, but once each is converted to the cost of driving 100 miles - electricity rate times kWh per 100 miles for the EV, price per gallon divided by miles per gallon for the gas car - the two sit side by side. The table uses a 28-mpg gasoline baseline for that comparison.
Most home charging happens on Level 1 (a 120-volt household outlet) or Level 2 (a 240-volt circuit), which differ in charging speed but draw the same residential electricity rate, so they cost the same per kWh. DC fast charging is high-power public equipment and is usually priced higher per kWh than home electricity. The home figures here therefore reflect residential rates only; actual costs shift with time-of-use pricing, charging losses, and how much of your charging happens on public fast chargers rather than at home.
EV charging FAQ
- Is it cheaper to charge an EV at home or use gas?
- In most states, home charging on residential electricity rates costs less per 100 miles than fueling a 28-mpg gasoline car. The table above shows the per-100-mile cost for both in each state, along with the difference. The gap is largest where electricity is cheap and gasoline is expensive, and narrows where residential rates are high.
- What's the difference between Level 1, Level 2, and DC fast charging?
- Level 1 uses a standard 120-volt household outlet and adds range slowly, making it suited to overnight top-ups. Level 2 uses a 240-volt circuit (the kind a dryer or oven uses) and charges several times faster, which is why most home chargers are Level 2. DC fast charging is high-power public equipment that can add a large share of range in minutes. The energy cost per kWh is the same at home regardless of Level 1 versus Level 2; the level affects how fast you charge, not the per-kWh rate.
- How is charging cost calculated?
- Cost per 100 miles equals the car's energy use over that distance multiplied by the price of electricity. The table uses a 30 kWh-per-100-miles efficiency figure and each state's residential electricity rate in cents per kWh. The gasoline comparison divides 100 miles by 28 mpg and multiplies by the state's price per gallon, so both numbers are expressed as dollars per 100 miles.
- Why does charging cost vary by state?
- Residential electricity rates are set by local utilities and regulators and differ widely across states, so the same car costs more to charge in a high-rate state than in a low-rate one. Gasoline prices also vary by state due to taxes and supply, which is why the EV-versus-gas difference is not the same everywhere.
- Does public DC fast charging cost the same as charging at home?
- No. The figures here are based on residential electricity rates for home charging. Public DC fast charging is typically priced higher per kWh than home electricity, so relying on it raises the per-100-mile cost above the home-charging estimates shown above.

Estimate only - not financial advice. Costs are estimates based on statewide average residential electricity rates and gasoline prices, a 30 kWh/100mi efficiency assumption, and a 28 mpg gasoline comparison. Your utility plan, time-of-use rates, and public DC fast charging prices can change the math.
