Formula
Total cost = depreciation + fuel + insurance + tax + parking + servicing + interest Fuel, metric = (total distance ÷ 100) × consumption × fuel price Fuel, imperial = total distance ÷ MPG × fuel price Interest = sum of monthly outstanding principal × monthly rate during ownership Monthly cost = total cost ÷ (years × 12)
Default assumptions
| Assumption | Value | Where it comes from |
|---|---|---|
| Depreciation, years 1–3 | 20 % per year on the remaining value | Estimate |
| Depreciation, year 4 onwards | 10 % per year on the remaining value | Estimate |
You can change every default above.
What this calculator does not account for
- The depreciation curve applies 20 % for the car’s first three years of life and 10 % after that. The age-at-purchase field starts it at the right point, so a used car is no longer depreciated like a new one.
- Loan interest is included as an annuity. Lease payments, down payments and balloon agreements are not.
- Tyres, inspections and major repairs have to go into the servicing figure yourself.
- Tax deductibility and company-car rules are out of scope.

Frequently Asked Questions

Yes. This calculator applies 20% annual depreciation for years 1-3, then 10% annually after that. You will see an estimated resale value at the end of your ownership period.
One-time purchase fees, registration costs, and major unexpected repairs are not included. The calculator focuses on predictable, recurring ownership costs. Add major repairs to your maintenance estimate if anticipated.
Yes. For EVs, estimate your energy cost by using your real kWh consumption and local electricity rate, then enter an equivalent per-distance cost. Maintenance can differ by model, so use your own service history or provider estimate.
The answer depends on your local prices and usage. Run this calculator for car costs, then compare that total with your annual transit passes and typical ride-sharing spend. The lower total cost for your own scenario is the better financial option.
Commonly missed costs include parking, tolls, registration, inspections, cleaning, financing costs, and depreciation. Add each of these with your own local numbers so your total ownership estimate reflects real out-of-pocket cost.
