Note: costs mentioned below are given in US dollars as a general point of reference — actual prices vary by country, currency, and local market.
A Level 2 home charger with installation typically costs $800-$2,200 depending on electrical work needed. If it saves you $0.05-$0.15 per mile versus relying on public charging, and you drive 12,000 miles/year, the payback period is usually 1-3 years — often faster where local rebates for home charger installation are available.

What this calculator does
This tool compares the total upfront cost of buying and installing a home Level 2 EV charger against the ongoing savings of charging at home (cheaper per kWh, especially on off-peak rates) versus relying primarily on public charging. It outputs a payback period in months or years, and a running total of net savings over time after payback.
What goes into the upfront cost
- Charger hardware — a Level 2 (240V) home charging unit typically costs a few hundred dollars, with pricing varying by amperage, smart features (scheduling, app connectivity), and brand.
- Electrical work — installing a dedicated 240V circuit, and any electrical panel upgrade if capacity is insufficient, is usually the larger and more variable part of total cost — a straightforward install near an existing panel costs far less than a run requiring trenching or a panel upgrade.
- Permits and inspection — many jurisdictions require an electrical permit for a dedicated circuit installation, adding a modest fee.
What goes into the ongoing savings
The core saving is the per-kWh price gap between home electricity (especially off-peak) and public charging (particularly DC fast charging, which carries a premium for speed). Every mile driven and charged at home instead of at a public charger banks that per-mile difference. A driver who currently relies heavily on public fast charging out of necessity sees the largest potential savings from switching most charging to home.
Worked example
| Scenario | Install cost | Annual mileage | Est. annual savings | Payback |
|---|---|---|---|---|
| Simple install, heavy public-charging reliance | $900 | 12,000 mi | ~$720 | ~1.3 years |
| Panel upgrade needed, moderate reliance | $2,000 | 10,000 mi | ~$450 | ~4.4 years |
| Simple install, light public-charging reliance | $800 | 8,000 mi | ~$280 | ~2.9 years |
What changes the payback period
- How much you currently rely on public fast charging — the more you currently pay premium public rates, the faster a home charger pays for itself.
- Local electrical work complexity — an existing panel with spare capacity near the parking spot makes install cheap; older panels needing an upgrade raise the upfront cost substantially.
- Available rebates or utility incentives — some utilities and local programs offer rebates for home charger installation or discounted EV charging rate plans, which can meaningfully shorten payback.
- Annual mileage — higher mileage means more charging events shifted from public to home rates, accelerating payback.
When it might not be worth it
If you already have free or low-cost workplace charging covering most of your needs, or you rarely drive enough to make the per-mile savings add up, a Level 2 home install may take many years to pay back — a simple Level 1 (standard outlet) setup, or continued reliance on existing free charging, may be more cost-effective in that specific situation.
Get a firm electrician quote before assuming the low end of the install-cost range applies — older homes and detached garages often need more extensive wiring work than expected. Check for a current utility or local rebate on home EV charger installation before calculating payback; these programs change and can meaningfully shift the math.
