How it works

Cost = energy × price per kWh, plus the session fee, plus the minutes × the per-minute price. Amounts are rounded to the smallest unit of your currency. If you give battery levels instead of kWh, the energy is the battery's gain ÷ charging efficiency, because you pay for what leaves the wall, not what lands in the battery.

Time-of-use tariffs (cheap nights, dear evenings) are in the EVFolk app, which splits a charge across your rate windows.

An estimate from the prices you enter. Taxes, idle fees and minimum charges on your bill may differ.

The app does these sums for you from your real charges: what you spent, what you saved against petrol and the CO2 you avoided. Use it on the web today, or on your phone.
