Estimated Current Value vs Years Owned
公式
Car Depreciation Curve
Cars depreciate fastest in the first few years, then the rate of loss slows. A declining balance model captures this pattern.
Formula
Current Value = Purchase Price x (1 - Depreciation Rate)^Years
The average car loses 20% in the first year, then about 15% per year after that. After 5 years, a typical car retains about 37% of its original value.
计算示例
A $35,000 car owned for 5 years at 15% annual depreciation.
- 01Current value = $35,000 x (0.85)^5 = $35,000 x 0.4437 = $15,530
- 02Total depreciation = $35,000 - $15,530 = $19,470
- 03Value retained = 44.4%
常见问题
Which cars depreciate the least?
Trucks, SUVs, and vehicles from Toyota, Lexus, and Porsche tend to hold value best. Luxury sedans and electric vehicles often depreciate faster.
Does mileage affect depreciation?
Yes. Average is 12,000-15,000 miles/year. Higher mileage increases depreciation. Very low mileage vehicles retain a premium.
When is the best time to buy used?
Cars 2-3 years old offer the best value: they have already absorbed the steepest depreciation but still have years of reliable life ahead.
