EV Range Calculator

Estimate an electric car's range from its battery size and efficiency.

Estimated range

333km

Estimated range
207 miles

Estimate assumes the battery capacity and efficiency you enter. Weather, speed and heating affect real range.

How this is worked out

Range in kilometres is usable battery capacity ÷ consumption per 100 km × 100, then converted to miles.

Worked example

  • 60 kWh usable
  • 18 kWh per 100 km

60 ÷ 18 × 100

333 km, about 207 miles

Assumptions and limits

  • Uses usable capacity, which is smaller than the headline battery size because of the buffer the car reserves.
  • Assumes constant consumption. Cold weather, motorway speeds, heating and load can cut real range by 20% or more.
  • Assumes charging from full to empty, which is not how most people drive.
