How these numbers are calculated
  • Fuel cost uses the car's combined MPG and the price you enter.
  • EV energy cost assumes 3.5 mi/kWh (UK average). Real efficiency varies by car and driving style.
  • Insurance is a rough estimate based on the car's insurance group — your actual quote depends on age, location, and history.
  • Depreciation assumes 40% loss over 3 years, scaled linearly. Premium brands and EVs can deviate significantly.
  • Road tax uses the published first-year and standard VED for the car's CO₂ band.
