EV Charging Cost Calculator UK

Work out how much your electric car really costs to run with your current home tariff. Enter annual mileage, vehicle efficiency, and charging split to estimate annual electricity use, charging cost, and pence-per-mile. This gives you a clearer benchmark than generic EV running-cost tables because it reflects your actual tariff and usage pattern.

If you have access to off-peak pricing, use the off-peak charging controls to model how much shifting overnight can reduce total EV charging spend. You can compare one EV against multiple vehicles in the same household, then test how changes in rates or mileage affect your annual bill. This is especially useful when choosing between tariff plans or deciding whether smart charging is worth it.

Use the scenario feature to compare present-day costs with a future setup, for example a second EV or a different time-of-use tariff. The results section highlights annual cost, total charging kWh, and cost per mile so you can make confident decisions before committing to a new tariff or charging routine.
