EV vs Combustion Running Cost Calculator

FREE TOOL

Enter your distance and prices to compare fuel, charging and road tax costs. Your inputs are calculated in this browser only. Nothing is stored or sent.

How to use it

The default values are an example only. Replace them with your real annual distance, your car’s real economy and the price at the charger you would use. Use one currency throughout.

Formulas

  • Combustion fuel = distance ÷ fuel economy × fuel price × years
  • EV charging = distance ÷ EV efficiency × charging price × years
  • Road tax difference = (combustion tax − EV tax) × years

Example

With the defaults, five years of fuel cost 9,000, charging costs 3,000, and the total difference is 6,000.

Limits

  • Vehicle price, subsidies, depreciation, insurance and maintenance are not included, and any of them can change the conclusion.
  • Tax reductions by vehicle age are not included.
  • EV efficiency varies by model and season.
