What This Calculator Estimates
This calculator estimates how much a vehicle may be worth after a set number of years using a fixed annual depreciation rate. It is useful for trade-in planning, ownership comparisons, and budgeting for replacement timing.
Formula / Method Used
- Enter the purchase price.
- Enter the annual depreciation rate as a percentage.
- Enter the number of years you want to project.
- The calculator uses future value = purchase price x (1 - depreciation rate)^years.
Worked Example
If a vehicle costs $32,000, depreciates at 15% per year, and you keep it for 5 years, the projected value is about $14,183. That implies about $17,817 in estimated depreciation over the period.
Common Mistakes
- Using a depreciation rate that is too low for the vehicle category.
- Assuming the same rate applies equally every year in real life.
- Ignoring mileage, accident history, and maintenance condition.
- Confusing projected value with trade-in cash after fees or payoff.

Frequently Asked Questions
How does this vehicle depreciation calculator work?
It applies the annual depreciation rate to the vehicle price year after year using a declining-balance method.
What depreciation rate should I use?
Use a rate that fits the vehicle type, market, mileage expectations, and ownership period you want to model.
Why can actual resale value differ from this estimate?
Mileage, condition, accidents, maintenance history, trim, market demand, and local pricing can all move resale value away from a simple model.
Does this include loan payoff or negative equity?
No. This page estimates future vehicle value only, not loan balance, payoff amount, or trade-in fees.
Can I compare several ownership scenarios?
Yes. Recalculate with different rates and years to compare optimistic and conservative value projections.
Limitations / Disclaimer
This calculator uses a simplified depreciation model. It does not include market shocks, maintenance history, mileage, financing, taxes, or dealer trade-in adjustments that can materially affect real resale value.
