USAHome charging costs and Level 2 charger payback calculator
See your real monthly fuel cost as an EV owner and how quickly a Level 2 home charger pays for itself. Note: the federal §30C home charger tax credit expired June 30, 2026 and is no longer factored into the payback estimate below — check the EV Incentives tool for state and utility rebates that may still apply.
Home charging cost and payback explained
Home charging is the cheapest way to run an EV, but the up-front cost of a Level 2 charger and its installation makes people hesitate. This calculator estimates your monthly home-charging bill from your mileage, your car's efficiency and your electricity rate, compares it with the equivalent gas cost, and shows how many months it takes for the fuel savings to repay the charger and installation.
Typical Level 2 installations range from a few hundred dollars for a nearby 240V outlet to well over a thousand for long wiring runs or panel upgrades. Even at the high end, most drivers recover the cost within one to two years of fuel savings.
Frequently asked questions
Do I need a Level 2 charger at all?
If you drive under about 30–40 miles a day, a standard 120V outlet (Level 1) can keep up overnight. Level 2 is worth it for longer commutes, cold climates, or if you want to charge fully overnight on off-peak rates.
Is there still a federal tax credit for home chargers?
The federal §30C home-charger credit expired on June 30, 2026. Many utilities and states still offer rebates — check the EV Incentives tool for your state before you buy.
Plug-in or hardwired?
Plug-in units on a NEMA 14-50 outlet are cheaper to install and portable if you move; hardwired units can deliver the full 48A and are required by code for some higher-power chargers.
