How this estimate works
Value is projected with a constant yearly percentage loss. You either enter the rate directly or enter a resale estimate you researched, from which the equivalent yearly rate is derived.
Formula
- Value(t) = price × (1 − d)^t
- d from your estimate = 1 − (resale ÷ price)^(1 ÷ years)
- Sensitivity = the same projection at d ± 5 points
Limitations
- Real resale depends on model demand, kilometres, condition, fuel type and city.
- No verified used-car price dataset is used; this is not a valuation.
Data used
No market valuation dataset is deployed. Your market estimate and the editable rate are kept separate and labelled.

Frequently asked questions
Is this my car's market value?+
No. It is an illustration from your assumptions. Check listings or a valuer for a real market price.
Which mode should I use?+
If you have found resale prices for the same model and age, use your estimate. Otherwise use an editable rate and test the sensitivity rows.
How accurate is this car depreciation estimate?+
It will provide an indicative estimate based on your inputs and the stated assumptions. Actual results can vary by location, equipment, tariff, and usage.
Can I use the result to make a purchase?+
Use it as a starting point, then confirm current prices, specifications, eligibility, and site requirements with a qualified provider.
