Trade-In Value Estimator
This trade-in value estimator gives a ballpark figure for what a vehicle might be worth, based on its original price, age, mileage and condition, using a standard depreciation-curve estimate. It's a starting point before you visit a dealer or get a real appraisal, not a guaranteed offer.
What the vehicle cost new (or what you paid, if bought used).
Years since the vehicle was new.
12,000 miles/year is the typical assumption used for depreciation estimates.
Be realistic — dealers will assess this closely.
Estimated trade-in value

A ballpark estimate — always get an actual valuation before negotiating.
Private sales typically fetch more than a dealer trade-in, but take more time and effort.
How to use this trade-in value estimator
- 1Original purchase price and vehicle age: the basics of the depreciation estimate.
- 2Average annual mileage: 12,000 miles/year is the standard assumption — higher mileage than that lowers the estimate, lower mileage raises it.
- 3Condition: be honest — dealers and private buyers will inspect closely, and an overly optimistic self-assessment just sets up a disappointing negotiation.
Understanding your results
Estimated trade-in value uses a standard depreciation curve (steeper in year one, then more gradual) adjusted for mileage and condition — it's directionally useful but not a guaranteed offer. Estimated private-sale value shows the commonly cited premium private sales fetch over a dealer trade-in, reflecting the extra effort and time a private sale takes.
The formula
Value = Original price × Depreciation curve × Mileage adjustment × Condition multiplierThe depreciation curve assumes roughly 20% loss in the first year (the steepest single-year drop for most vehicles) and about 15% per year after that. Mileage above or below the 12,000-mile/year expectation adjusts the value up or down, and a condition multiplier further scales the result based on how well-maintained the vehicle is.
A worked example
A $32,000 car, 4 years old, averaging 12,000 miles/year (right at the expected pace), in good condition: after the depreciation curve (20% in year one, 15% each year after), the estimated value is roughly $15,700 — with private-sale value estimated around $18,100, reflecting the typical premium over a dealer trade-in.
Notes for the UK, US and India
Real trade-in offers also weigh local market demand for that specific model, accident history (via a vehicle history report), and the dealer's current inventory needs — a dealer overstocked on your model may offer less regardless of condition. Always get an in-person appraisal or an online instant-offer tool's real quote before treating any estimate as final.
Frequently asked questions
Why is the private-sale estimate higher than the trade-in estimate?+
Dealers factor in reconditioning costs, their own profit margin, and the convenience of an instant transaction — private buyers pay closer to true market value since they're not absorbing those costs, but a private sale takes more time and effort to arrange.
Does accident history affect this estimate?+
No — this estimator doesn't know your vehicle's specific history. A clean accident-free history typically supports a higher real value than this estimate; a history of accidents typically lowers it below this estimate.
How accurate is the 20%-then-15%-per-year depreciation assumption?+
It's a reasonable industry-typical average, but actual depreciation varies significantly by make and model — some vehicles hold value much better (or worse) than this generic curve assumes. Check a model-specific valuation tool for a tighter estimate.
