EV Charging Cost Calculator
Estimate your cost per mile, per month, and per year -- based on your vehicle's efficiency, your electricity rate, and how much of your charging happens at home versus in public.
Check your car's app or window sticker. Most EVs run 2.0-4.5 mi/kWh depending on size and driving conditions.
$0.15/kWh is a rough national average -- check your utility bill for your actual rate.
Cost per mile (blended)
5.0¢
This is an estimate based on the inputs above, not a guarantee. Real-world cost varies with driving conditions, temperature, charging losses, and your actual electricity rate. Check your utility bill and vehicle app for your real numbers.
How the Math Works
Cost per mile comes down to one formula: your electricity rate (in $/kWh) divided by your vehicle's efficiency (in miles per kWh). A more efficient car or a cheaper electricity rate both lower your cost per mile -- there's no way around that relationship.
Charging speed itself doesn't change this math -- a faster charger gets you to the same cost sooner, not a lower cost. If you're deciding what charger to install rather than what it costs to drive, see our EV charger installation cost guide or installation cost calculator.
Calculator FAQs
Is this an exact number?
No. This tool computes a cost estimate from the inputs you provide -- your vehicle's real-world efficiency, your electricity rate, and how many miles you drive. It's the same cost-per-mile math (rate per kWh divided by efficiency in miles per kWh) used throughout our charging speed and cost guides, applied to your specific numbers. Actual cost varies with driving conditions, temperature, and your actual utility rate.
Where do I find my vehicle's efficiency?
Check your car's onboard app or trip computer for a real-world miles-per-kWh figure -- that's more accurate than the EPA-rated number for your actual driving. If you only have a kWh/100 miles figure (common on some manufacturer apps), use the unit toggle in the calculator instead of converting it yourself.
Why does the home/public charging split matter?
Public charging (especially DC fast charging) is almost always priced higher per kWh than home electricity. If you charge mostly at home but occasionally use public chargers on trips, blending the two rates by their approximate share of your total miles gives a more realistic annual cost than assuming 100% of your charging happens at either price.
