How Much Does It Cost to Charge an EV?
This is the running cost of driving electric — what you pay in electricity, not the one-time cost of installing the charger. Here's the simple math, a real-world monthly example, and how it stacks up against a tank of gas.
The math is simpler than you'd think
Charging cost comes down to one little equation: kilowatt-hours used × your electricity rate. Your car's battery is measured in kilowatt-hours (kWh), and your utility bills you per kWh — the U.S. average is around 16–17¢/kWh, though it swings from roughly 11¢ in cheap states to 30¢+ in the priciest.
So “filling up” a typical 60 kWh battery from near empty costs about $8–$12 at the average rate — and that gets you somewhere around 250 miles. Put another way, most EVs cost roughly 3 to 5 cents per mile to drive at home.
A real monthly example
Say you drive 1,000 miles a month and your car uses about 0.3 kWh per mile. That's 300 kWh. At 17¢/kWh, you're looking at about $51 a month added to your electric bill — for all of your driving. Charge on a cheaper overnight rate and it can drop well below that.
How it compares to gas
A gas car getting 25 mpg with gas at $3.50 a gallon costs about 14¢ a mile in fuel. Charging the same miles at home — at 3–5¢ a mile — is roughly a third of that or less. Over a year of typical driving, the difference is commonly a few hundred dollars in your pocket, before you count lower maintenance.
How to pay even less
- •Charge overnight on a time-of-use (TOU) plan — many utilities price off-peak power at a fraction of the daytime rate.
- •Do most of your charging at home. Public DC fast charging often costs 30–50¢/kWh, two to three times the home rate.
- •Pair it with solar if you have it — daytime charging can be close to free.
- •A Level 2 charger lets you schedule charging for the cheapest hours automatically.
Running costs are the easy part — the bigger one-time number is installing the charger itself. The cost calculator gives you a ballpark for that, and the Level 1 vs Level 2 guide explains why a home charging station charges 5–7x faster than a wall outlet.
Common questions
How much does it cost to charge an electric car at home?
For most people, charging at home costs roughly 3–5 cents per mile. A full charge of a typical 60 kWh battery runs about $8–$12 at the U.S. average electricity rate (~16–17¢/kWh), and that gets you somewhere around 250 miles. Your exact cost depends on your electricity rate and your car's efficiency.
Is it cheaper to charge an EV than to buy gas?
Almost always, yes. Charging at home tends to cost around 3–5 cents per mile, versus roughly 12–15 cents per mile for a gas car getting 25 mpg at $3.50 a gallon. Over a year of normal driving that's often several hundred dollars saved.
Does charging an EV raise my electric bill a lot?
It's noticeable but rarely dramatic. Driving about 1,000 miles a month adds roughly $40–$60 to a typical bill. Many utilities offer cheaper overnight (time-of-use) rates that can cut that meaningfully if you charge while you sleep.
Is home charging cheaper than public charging?
Usually by a wide margin. Home electricity is commonly 13–20¢/kWh, while public DC fast chargers often run 30–50¢/kWh or more. That's the main reason most EV owners do the bulk of their charging at home.
