Your charging cost

This is an estimate, not advice.

See how we worked this out
  1. Energy used a year = miles a year ÷ miles per kWh.
  2. Home cost = home share of that energy × your home rate. Public cost = the rest, split between slow and fast chargers and rapid chargers by the share you set.
  3. Charging losses are not included, so real costs may be slightly higher.
