Car Cost of Ownership Calculator
Add up depreciation, fuel, insurance, maintenance and interest to see the true cost of a car per year and per km.
Quick answer
Car cost of ownership is the total spent on a car over the years you keep it: depreciation (price minus resale value) plus fuel, insurance, maintenance, registration and loan interest, divided by years and distance for per-year and per-km cost.

Assumptions & method
- Depreciation = price − resale value. Resale value = price × resale %, or price × (1 − rate)^years when an annual depreciation rate is chosen.
- Fuel = distance per year × years × efficiency ÷ 100 × fuel price. Efficiency and fuel price stay constant.
- Insurance, maintenance and registration are yearly amounts multiplied by the years owned, with no inflation.
- Loan interest is the total interest you enter. The loan principal is not a cost here, because it is part of the price.
- Cost per km = total ÷ (distance per year × years). Parking, tolls, fines and the value of the money tied up in the car are not included.

The true cost of owning a car
The sticker price is only part of what a car costs. Over the years you pay for the value it loses, for fuel, insurance, servicing and registration, and for interest if you borrowed to buy it. Adding these gives a total cost of ownership, which you can divide by the years you keep the car or the distance you drive to get a yearly or per-kilometre figure. That number makes it easier to compare a cheaper car with higher running costs against a pricier one that costs less to run, and to judge whether owning a car fits your budget compared with other ways of getting around.
