Quick answer
Convert annual ownership cost into cents per mile
This calculator adds annual vehicle costs and divides them by mileage to show what each mile costs after fuel, fixed costs and depreciation.
The method
Every cost divided by every mile
Annual energy, registration, insurance, maintenance, finance costs and depreciation are divided by annual mileage.
Include depreciation for a true ownership cost.
Higher mileage spreads fixed costs further.
Unexpected major repairs are excluded.
Cost per mile questions
Why is cost per mile useful?
It makes fixed and variable ownership costs easier to compare across vehicles, mileage levels or work reimbursement plans.
Should finance payments be included?
Include finance interest or fees for ownership cost. Principal repayment is partly a balance-sheet item, so compare consistently.
