Your Summary
Explanation
About Car Depreciation Calculator
This calculator estimates how much a vehicle is worth after a period of ownership using the declining-balance model: enter the purchase price, an annual depreciation rate, and the number of years, and it returns the estimated value, the total dollar depreciation, and the percentage of value lost. The chart plots the estimated value at the end of each year.
Depreciation is applied as Value = Price × (1 − rate) raised to the number of years, so each year's loss is calculated on the reduced value rather than the original price. Real-world resale value also depends on make, mileage, condition, and market demand, so treat the result as a planning estimate.
Formula & Mathematical Calculation
Estimated Value = Purchase Price × (1 − Annual Depreciation Rate)^Years
Total Depreciation = Purchase Price − Estimated Value
Value Lost (%) = (Total Depreciation ÷ Purchase Price) × 100
Calculation Example
A $32,000 vehicle depreciating 15% per year is worth about $14,198.57 after 5 years — a total depreciation of $17,801.43, or 55.63% of its original value.
