Car Depreciation Calculator: What’s Your Car Worth Now?
Cars lose value fastest in their first year — often around 20% the moment a car is no longer “new” — then continue depreciating at a slower, more gradual pace each year after. Enter your car’s original purchase price and age above for an estimate of what it’s likely worth today, based on this general pattern.
Why the first year hits hardest
A car’s value drop in year one isn’t really about wear and tear — a car with 500 miles on it after a year isn’t mechanically much different from when it was purchased. The bigger factor is that “new” carries real market value on its own, and a car loses that status the moment it’s registered and driven off the lot. After that initial adjustment, depreciation settles into a steadier, more gradual decline driven by actual wear, mileage accumulation, and the normal aging of components.
How the estimate is calculated
This calculator applies a two-phase model: a roughly 20% decline spread across the first year, then a compounding 15% annual decline afterward. These are general figures reflecting a typical depreciation curve, not a claim about any specific make or model — some vehicles hold value notably better than average, and others depreciate faster, based on factors like reliability reputation and demand that this general estimate doesn’t capture.
How to use the calculator
- Enter the original purchase price.
- Enter the car’s current age in years — decimals are fine (like 2.5 for two and a half years).
- Read the estimated value and how much has depreciated so far, both in currency and as a percentage.
A general depreciation curve
| Age | Roughly % of original value remaining |
|---|---|
| 1 year | ~80% |
| 3 years | ~58% |
| 5 years | ~42% |
| 10 years | ~19% |
These are illustrative figures from the calculator’s general model — your specific car’s actual value depends on its make, model, mileage, condition, and local market demand.
Tips for slowing depreciation
- Keep mileage reasonable relative to the car’s age — unusually high mileage for the car’s age tends to accelerate perceived depreciation beyond this general estimate.
- Maintain a service record — documented maintenance history supports resale value more than most owners expect.
- Keep the car clean and address minor cosmetic issues — condition matters more to buyers than most people assume.
- Research your specific model’s typical resale reputation before buying, if minimizing depreciation matters to you — this varies more by model than by almost any other factor.
Frequently asked questions
Which cars hold their value best?
This varies significantly by model and shifts over time based on reliability reputation and demand — checking current resale-value rankings for the specific models you’re considering gives a more accurate picture than any general rule.
Does the color of a car affect its resale value?
Modestly, in some markets — common, neutral colors generally have broader buyer appeal at resale than unusual or highly specific colors, though this effect is typically smaller than age, mileage, and condition.
Does leasing avoid depreciation risk?
In a sense — with a lease, the leasing company absorbs the depreciation risk rather than you, since you’re not responsible for the car’s resale value at the end of the term, though this is factored into the lease payment itself.
What does it mean to be “underwater” on a car loan?
It means you owe more on the loan than the car is currently worth — common in the first year or two of ownership, since the car depreciates faster than a typical loan balance declines early on.
Is there a good time to sell relative to depreciation?
Some owners choose to sell just before a steeper depreciation milestone (like crossing a round-number mileage or age threshold that buyers commonly filter by), though this is a minor optimization compared to overall condition and market timing.
