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.
