EV Home Charging Cost Calculator

Estimate the cost per full charge and per mile of charging an electric vehicle at home.

Computed in your browser — nothing you enter is uploaded. Figures are presented for United States against IRC 2024, and every formula is cited under regulatory standards below.

Cost per full charge

11.25 $ per full charge

Check your inputs

This assumes charging from empty to full at 100% efficiency — real-world charging has some energy loss (typically 10-15%) and most drivers charge partially rather than always fully depleting the battery first.

Cost per mile
0.05 $/mile

Running these inputs gives 11.3 $ per full charge as the cost per full charge. Expect some drift against the real job; the calculation is solid but conditions on site are not. Currently reading for United States under IRC 2024 — pick a different market above and the figures re-cast accordingly.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

  • Cost per full charge = battery capacity (kWh) x electricity rate ($/kWh); cost per mile = cost per full charge / miles of range per charge

Frequently asked questions

How does this compare to gasoline cost per mile?
Home EV charging is very often cheaper per mile than gasoline, especially at off-peak electricity rates, though the exact comparison depends on your local electricity rate, gas prices, and both vehicles' efficiency — this calculator gives the EV side of that comparison.
Does public fast charging cost the same as home charging?
No, usually more — public DC fast chargers typically charge a premium per kWh compared to home electricity rates, so most EV owners charge at home for routine use and reserve public fast charging for road trips.
Does charging speed (Level 1 vs Level 2) affect the cost?
Not directly — the total energy (kWh) needed to charge the battery is the same regardless of charging speed, so cost per charge is essentially the same; faster charging (Level 2) just gets you there sooner.
