Vehicle Depreciation Estimator
Estimate current and future vehicle value using annual depreciation assumptions
Estimated time

Depreciation Inputs
Estimate current and future vehicle value from purchase price, age, and annual depreciation rate.
$
Annual percentage decline in value. Example: 15 means value is multiplied by 0.85 each year.
%
Formula Summary
Current value = purchase price x (1 - annual rate)^age years
Projected future value = current value x (1 - annual rate)^forecast years
Depreciation to date = purchase price - current value
Additional depreciation = current value - projected future value
Remaining value % = projected future value / purchase price x 100
How It Works
This estimator uses a constant annual depreciation rate so you can build quick what-if scenarios for ownership planning.
Use conservative and aggressive rates to create a value range before resale or trade-in decisions.
- Current value is estimated from original price and current age.
- Future value projects additional depreciation from today forward.
- Total depreciation to date = original price - estimated current value.
- Additional projected depreciation = current value - future value.
- Remaining value ratio = projected future value / original price.
Example Calculations
Recent crossover
$36,000 purchase, 2 years old, 15% annual depreciation, 3-year forecast
Current ~$26,010, projected ~$15,958 after 3 more years
Even moderate annual rates compound strongly over multi-year ownership windows.
Older sedan
$28,000 purchase, 6 years old, 12% annual depreciation, 2-year forecast
Current ~$13,670, projected ~$10,590
Depreciation slows in absolute dollars as vehicle value gets lower.
High-depreciation scenario
$55,000 purchase, 1 year old, 20% annual depreciation, 4-year forecast
Projected value drops to about one-third of original price
High annual rates can significantly alter total ownership cost assumptions.
Frequently Asked Questions
Why use one annual depreciation rate?
It keeps assumptions transparent for planning. Real-world depreciation is not linear and can vary year to year.
Can this replace a trade-in quote?
No. Use this for planning and then validate with real market comps or dealer appraisal tools.
What rate should I pick?
Common planning ranges are 10% to 20% annually depending on vehicle type and local market conditions.
Does mileage affect this estimate?
Not directly in this simplified model. Choose a higher or lower annual rate to reflect expected mileage impact.
