EV Charging Cost Calculator
What it costs to charge an electric car
Wondering what it costs to 'fill up' an EV? Enter the battery size, your electricity rate and how much you're charging to see the cost — and the cost per mile.
Charging at home is cheap
Charging cost is simply kWh used × your electricity rate. Add your car's range to get a cost-per-mile that you can compare directly against gasoline (see the fuel cost calculator).
Home vs. public charging
Home (Level 1 or 2) charging at residential rates is the cheapest by far — often the equivalent of well under $1.50 a gallon. Public DC fast charging is far more expensive per kWh and sometimes billed by the minute, so it's best saved for road trips rather than daily top-ups.
Why you rarely charge 0–100%
Most EV owners charge to about 80% for daily use to protect battery longevity and only fill to 100% before a long trip. Charging losses mean you draw a few percent more from the wall than lands in the battery, and time-of-use plans make overnight, off-peak charging cheaper still — adjust the rate above to match your plan.
EV Charging Cost Calculator: frequently asked questions
How much does it cost to charge an EV?
Roughly the battery size (kWh) times your electricity rate — often a few dollars for a substantial charge at home.
Is charging an EV cheaper than gas?
Usually yes, especially charging at home off-peak; compare the cost-per-mile here against your gas vehicle's.
How much does it cost to charge an EV per month?
Multiply your typical monthly miles by the cost-per-mile this tool gives. For example, 1,000 miles at roughly 4 cents per mile is about $40 a month charging at home — usually far less than the gasoline it replaces.
