Car Depreciation Calculator
Estimate how much a car will be worth in the future. Enter the purchase price and this calculator models the typical curve of a large first-year drop followed by a gradually declining rate.
What is car depreciation?
A car starts losing value the moment it is purchased, and new cars in particular tend to depreciate the most during their first year on the road. This is largely because a car becomes a "used" vehicle the instant it is registered, and because newer model years quickly make older ones look dated. From the second year onward, the rate of decline typically slows down and keeps easing year after year.
This calculator lets you enter the purchase price along with a first-year depreciation rate and a rate for subsequent years, then projects the estimated resale or trade-in value for each year going forward based on that typical curve. Use it to plan the timing of your next trade-in or to compare how different vehicles hold their value over time.
How to use this calculator
- Enter the purchase price Use the total price paid for the new or used car, including tax and options, for the most accurate estimate
- Check or adjust the first-year rate The default of 20% is a common industry estimate, but it varies by model and popularity
- Check or adjust the rate for later years The default of 15% reflects a typical, gradually slowing decline
- Set how many years to project Enter the number of years until you plan to trade in or sell the car to see its estimated value at that point
Tips for getting more out of it
- Many new cars lose 40-50% of their purchase price within the first three years, which is a useful benchmark when planning a trade-in cycle.
- Even for the same model, popular colors, trims, and factory options can affect the resale price.
- If you still have an auto loan, check whether the estimated trade-in value would leave you owing more than the car is worth (negative equity) before trading it in.
- For a precise number, consider getting quotes from multiple dealers or online instant-offer services rather than relying on estimates alone.
When this calculator is useful
Planning the timing of a trade-in
Compare the projected trade-in value against your remaining loan balance to decide when trading in makes financial sense
Comparing resale value across vehicles
Adjust the depreciation rates to see how a vehicle with strong resale value differs from one that depreciates quickly
Checking for negative equity before trading in
Compare the estimated value against your auto loan payoff schedule to see whether you would still owe more than the car is worth
Glossary
- First-year depreciation
- The sharp drop in value a car experiences in its first year, mainly because it immediately becomes a used vehicle once registered and because newer model years arrive soon after.
- Declining balance
- A pattern where the amount lost each year gradually shrinks. Car values typically drop steeply in year one, then keep depreciating at a slower, easing rate in later years.
- Residual value
- The portion of a vehicle's original value that remains after a given period. It is the basis for lease residuals and a useful benchmark for estimating trade-in prices.
- Trade-in value
- The amount a dealership offers for your current vehicle when you buy another one from them. It can differ from a typical depreciation curve based on market demand and vehicle condition.
Frequently asked questions
Side Note — Why a "new" car becomes "used" the moment you drive it off the lot
The instant a new car is registered, it is classified as a used vehicle in the resale market, even if it has been driven only a few miles. Because a car that has already had an owner cannot be sold as brand new again, its value drops sharply the moment the paperwork is signed. This is the origin of the well-known saying that a new car loses value the second you drive it off the lot.
Not every car depreciates at the same pace, though. Some limited-production models and well-maintained classic cars can actually gain value over time. Among ordinary mass-market vehicles, models known for strong resale value tend to hold their price better, while models that have fallen out of fashion or are approaching a redesign often depreciate faster than average.
If you plan to trade in your car again in a few years, it helps to think not just about the sticker price today, but about how much value the car is likely to retain down the road. That perspective can make a real difference in your total cost of ownership.
