How this car depreciation calculator works
The calculator applies the depreciation rate you enter to the remaining vehicle value each year. If the separate first-year option is enabled, it applies that rate in year one and the regular annual rate after that.
Annual depreciation assumptions
Depreciation is assumption-based. Real resale values can vary with mileage, condition, demand, location, timing and vehicle history.
What this calculator does not include
This calculator does not use live valuation data, appraise a vehicle, predict exact resale value, include loan balance, or provide financial, insurance or tax advice.
Key terms and assumptionsShort notes about depreciation, future value, first-year assumptions and live market data limits.
- Assumption-based value

- First-year depreciation
- If enabled, the first-year rate is applied in year one and the regular annual rate is applied after that.

FAQs
What is car depreciation?
It is the estimated loss in vehicle value over time.
Does this predict my car's resale value?
No. It projects value from the depreciation rate you enter and does not use live vehicle valuation data.
Why include a separate first-year rate?
Some cars lose more value early. A separate first-year assumption makes that scenario easier to test.
Does mileage affect depreciation?
Mileage can affect real resale value, but this focused version does not model mileage directly.
Can depreciation be 0?
Yes. It means no value loss in the projection.
Can depreciation be over 100%?
No. The calculator rejects depreciation rates at or above 100%.
Does this include loan balance?
No. Use auto loan tools for payoff or remaining-balance questions.
Is this an appraisal?
No. It is a simple assumption-based estimate.
