How Much Does It Cost to Charge an Electric Car?

Published 2026 - 4 min read

The short answer: charging at home usually costs between $8 and $15 for a typical full charge, while public fast chargers can cost two to three times that. Your real number comes from two inputs - how many kilowatt-hours your car uses and what you pay per kWh.

The basic formula

Electricity is sold in kilowatt-hours (kWh). A car that uses about 0.24 kWh per mile (60 kWh battery, 250 mile range) driven 12,000 miles a year needs about 2,900 kWh. At $0.15/kWh at home, that is roughly $430 a year - versus $1,400 or more for the same miles in a 28 MPG gas car at $3.20 a gallon.

Home charging is the lever

Home electricity is typically 10-20 cents per kWh. Public Level 2 and DC fast chargers run 30-60 cents. Charging mostly at home is what makes an EV dramatically cheaper to run; relying on public chargers eats most of the savings.

Estimate your own car

Use the EV charging cost calculator - enter your battery size, range, and rates, and it returns cost per full charge, per mile and per year.

Worked numbers for a typical car

A 60 kWh battery with 250 miles of range uses about 0.24 kWh per mile. Charging 85% at home at $0.15 and 15% in public at $0.45 produces an average near $0.20/kWh. Over 12,000 miles that is about $570 a year - against roughly $1,370 for a 28 MPG gas car at $3.20 a gallon. The same EV charged only in public could cost $1,100+, which shows why home charging matters.

The three cost tiers

• Home, off-peak (10-15 cents/kWh): cheapest, often under $15 for a full charge.
• Public Level 2 (20-40 cents): about 2x home.
• DC fast charging (40-60+ cents): the most expensive way to run an EV.

Hidden factors that change the bill

Charging losses add about 10% to what you pay for. Time-of-use plans can cut home charging cost in half if you charge overnight. Free workplace charging can make an EV nearly free to run. And a home charger install is a one-time cost, not a per-charge one.

Comparing to gas honestly

Use your EV's real range and your real blend of home and public charging. Most owners who charge mostly at home cut their fuel bill by two-thirds or more; owners who depend on fast chargers see much of the advantage disappear.
