EV Cost Per Mile Calculator

Estimate an EV electricity cost per mile.

Use this calculator

Enter your EV’s battery capacity, expected range and electricity price.

Method: Battery capacity ÷ range gives kWh per mile; multiplying that by electricity price gives pence per mile.

What your result means

The result estimates electricity cost per mile from the battery capacity, estimated range and electricity price you enter. It also shows the energy per mile, miles per kWh, cost per 100 miles and an estimated full-charge cost.

Worked example

Using a 60 kWh battery, 240-mile range and 25p/kWh:

Energy use
0.25 kWh/mile
Efficiency
4 miles/kWh
Electricity cost
6.25p
Cost per 100 miles
£6.25
Full charge cost
£15.00

This is an estimate based only on the battery, range and price values entered.

Formula

EV cost per mile (p)=Battery capacity (kWh)×Electricity price (p/kWh)Range (miles)\text{EV cost per mile (p)}=\frac{\text{Battery capacity (kWh)}\times\text{Electricity price (p/kWh)}}{\text{Range (miles)}}

Helpful questions

What does pence per mile mean for an EV?

It is the estimated electricity cost for each mile driven using the inputs above. It makes it easier to compare different vehicle or energy-cost assumptions.

What electricity price should I enter?

Enter the price per kWh that you want to model. The result changes directly with that price, so use a value that reflects the charging cost you expect.

Why might real charging cost differ?

This calculator estimates cost from the entered battery, range and electricity price. If those inputs differ from the energy-to-range relationship you experience, your real cost will differ.

How can I compare this with petrol or diesel?

Compare the result with the EV vs Petrol Cost Per Mile calculator or the EV vs Diesel Cost Per Mile calculator.
