EV charging cost calculator

Estimate how much an EV charging session may cost, how long it may take, how many miles it may add, and the pence per mile based on your electricity price and efficiency.

Calculate charging cost and time

Charging speed can slow near the top of the battery, and real cost can vary by tariff, charger fees and vehicle efficiency. Use this as a planning estimate.

Quick answer: for a 60kWh EV charging from 20% to 80%, a 7.4kW home wallbox usually suits overnight charging. The cost depends mainly on the p/kWh tariff and the energy added after charging losses.

Common UK charging examples

3-pin plug

Backup charging at home. Slow but useful in emergencies.

2.3kW

Home wallbox

Typical overnight home charging speed for many UK drivers.

7.4kW

Rapid public

Useful for longer journeys, but session cost is often higher than home charging.

50kW+

EV charging cost FAQ

How is EV charging cost calculated?

Estimated cost is the energy drawn from the charger multiplied by the electricity price. The tool adds a charging loss percentage because the energy taken from the socket is usually higher than the energy stored in the battery.

Why is public charging more expensive?

Public charging prices can include network costs, maintenance, parking location costs and rapid charger infrastructure. Home off-peak charging is often cheaper when available.

Why is the time only an estimate?

EV charging speed depends on the car, battery temperature, charger output, battery percentage and charging curve. Many cars slow down as they approach a high state of charge.
