How to calculate
Estimate a vehicle’s future value, value loss, and retained-value percentage using a constant annual depreciation rate.
Future value = purchase value × (1 − annual depreciation rate)^years.
Worked example
Purchase value: 40000; Annual depreciation (%): 20; Years: 3.
Estimated resale value: 20,480 ; Estimated value lost: 19,520 ; Purchase value retained: 51.2 %.
Assumptions and limits
Actual resale value depends on model, age, mileage, condition, accident history, market demand, currency, and location. Use live market quotes for a transaction decision.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
The model applies the same percentage reduction to each year’s remaining value. It is a scenario rather than a market valuation.
When this tool is useful
Estimate vehicle value under a constant annual depreciation assumption.

Frequently asked questions
Does a car depreciate at a constant rate?
Not necessarily. Model, age, mileage, condition and local demand affect resale values; use actual market quotes for a sale decision.
