How Is Car Depreciation Calculated?
Depreciation follows the declining-balance method: each year’s loss is a percentage of the previous year’s value, not the original price. The formula:
Value This Year = Last Year’s Value × (1 − Annual Depreciation Rate)
The sharpest drop is year 1 (15–25%), slowing gradually. By year 7+, the curve flattens and most cars retain around 25–35% of their original price.
5-Year Retention Rate by Vehicle Type
Trucks and SUVs generally hold value better than sedans. Luxury cars and some EVs depreciate fastest. Below is the average 5-year retention by type:
5-Year Depreciation Example
A $35,000 standard sedan depreciating at typical market rates:
| Year | Est. Value | Annual Loss | Cumulative Loss |
|---|---|---|---|
| Year 1 | $28,000 | -$7,000 | 20% |
| Year 2 | $23,800 | -$4,200 | 32% |
| Year 3 | $20,706 | -$3,094 | 41% |
| Year 4 | $18,215 | -$2,491 | 48% |
| Year 5 | $16,211 | -$2,004 | 54% |
How to Minimize Depreciation Loss
1. Buy a CPO vehicle (2–3 years old). The first owner absorbs the steepest drop (30–40%). You get near-new features at a significantly lower price.
2. Choose value-retention brands. Toyota, Honda, and Subaru average 5-year retention of 45–55%, outperforming European luxury brands and most domestic sedans.
3. Keep mileage in check. Staying under 15,000 miles per year preserves value. Every extra 10,000 miles can reduce resale value by 5–10%.
4. Maintain service records. A complete maintenance history can add 5–10% to resale value and speed up the sale significantly.
