True cost of owning a car

The sticker price is only the first payment. The real cost of a car is a cash flow that runs for years, and depreciation — the largest slice — is invisible until the day you sell. Enter the price, how long you keep it, the yearly running costs and the expected resale value; the tool works out the total cost of ownership, the yearly and monthly average, and the cost per unit of distance.

Roughly what it sells for at the end; when unsure, estimate low.

Result

A car costing 30,000 kept for 5 years really costs about 35,000: depreciation 18,000 (the biggest slice) plus 3,400 of running costs a year. That is roughly 7,000 per year, 583 a month, and 0.58 per unit of distance.

Total cost splits in two: one-off depreciation and running costs that pile up year after year.

The result follows the running costs and resale value you enter; it is not purchase advice.

Assumptions & limits

No financing interest here (cash basis); a loan adds cost on top. Resale is the least certain figure, so estimate it low. Once you have the yearly average, compare it against ride-hailing, renting and public transport before setting a budget.
