Car True Cost Calculator
The real cost of owning a car, after resale value.
- What is the true cost of owning a car?
- It's the loan payments and interest you pay minus what the car is worth when you sell or trade it in — the actual money that leaves your pocket over the ownership period, not just the sticker price.
- Why isn't the loan payment the full cost?
- A loan payment ignores that the car itself is an asset losing value. Two loans with the same payment can have very different true costs if one car depreciates faster.

What Counts as the "True Cost" of a Car?
A car loan payment only tells part of the story, because the car itself is an asset that loses value. This calculator adds the down payment, loan payments made, and running costs (insurance, maintenance, fuel), then subtracts what the car is actually worth — its estimated resale value minus any remaining loan balance — at the end of your ownership period.
The result is the net cost of ownership: what actually left your pocket after accounting for the equity you get back at sale or trade-in. Two loans with an identical monthly payment can have very different true costs if one car depreciates faster than the other.
How this is calculated
Net cost = down payment + loan payments made + running costs − (resale value − remaining loan balance).
Assumptions
- Depreciation is modeled as a constant percentage of value lost per year.
- Running costs (insurance, maintenance, fuel) are flat annual estimates.
- Assumes you sell or trade in the car at the end of the ownership period, at the depreciated value minus any remaining loan balance.
- Excludes taxes, registration fees, and financing add-ons.
