How can I estimate the payback time of a home EV charger?
The calculation needs an installation quote and a realistic alternative charging cost. It should not assume that all driving immediately switches to cheaper home energy.

A closer look
Calculate the avoided cost
If a hypothetical installation costs 900 and saves 0.20 on each of 150 billed kWh per month, the simple saving is 30 per month and simple payback is 30 months. That example excludes maintenance, finance, tariff changes and any effect on other household electricity costs.
Test the amount you will really use
Reduce the assumed home-charging quantity for travel, holidays or unavailable parking. If only 75 kWh shifts each month in the example, simple payback doubles to 60 months. Use a property-specific installation quote and confirm permissions before treating the estimate as a purchase plan.
