Even with zero miles, your 4-year-old car has lost roughly 49% of its original purchase price. This surprises many owners, but age is the biggest driver of depreciation, not mileage alone.
Why Age Matters More Than You Think
Your car depreciates on a strict timeline. Here's what happens to a typical vehicle:
| Year | Value Lost | Remaining Value |
|---|---|---|
| Year 1 | 16% | 84% |
| Year 2 | 12% | 72% |
| Year 3 | 11% | 61% |
| Year 4 | 9% | 52% |
| Year 5 | 7% | 45% |
Your 4-year-old car sits at year 4, which means it's already lost about half its value. The clock on depreciation starts the moment you own the car, regardless of whether you drive it.
The Real Cost of Sitting Unused
Zero miles sounds like a benefit, but it doesn't stop the depreciation clock. Cars lose value for several reasons beyond wear and tear: newer model years arrive, technology ages, and market demand shifts. A 4-year-old model is simply older in the eyes of buyers, even if the odometer shows zero.
Low mileage does help, though. If you had driven an average 13,500 miles per year for four years, your car would show 54,000 miles and be worth even less. But that advantage only goes so far against the reality of age.
What You Can Do Now
Understand your car's actual market value by checking recent sales of similar 4-year-old models in your area. Use this realistic number as your baseline for insurance, trade-in negotiations, or selling. If you're keeping the car, focus on maintenance to slow further depreciation. Proper upkeep costs far less than losing value through neglect.
If you're considering selling, remember that your car will continue losing 7-9% of its current value each year. The longer you wait, the less you'll get.
