How to Use

Enter your car value, annual mileage, fuel economy, and running costs to calculate the true total cost of ownership per year and per mile. Depreciation is the single biggest cost for most drivers — often larger than fuel. This calculator uses a 15% annual depreciation estimate and a standard road tax figure; adjust servicing and insurance to match your own situation.
