The estimate linearly interpolates published factors of 100%, 81%, 69%, 58%, 49%, and 40% at years 0–5, then reaches zero at 10.5 years. Actual resale value varies by model, condition, mileage, and market.

FAQs

Is this a resale-price prediction?

No. It is a bounded planning estimate using the selected curve and does not model mileage, condition, local market, trim, or accident history.

Understand depreciation trends

Learn how quickly cars lose value in general, helping you make informed purchase decisions or compare different age scenarios.

Example: Compare the estimated value of a car at 3 years vs. 7 years.

Frequently Asked Questions

How does the car depreciation calculator work?
It uses a standard depreciation curve to estimate how a vehicle's value decreases with age. You input the original purchase price and the vehicle's age, and it calculates an estimated current value based on typical depreciation patterns.
What factors does this calculator consider?
This calculator only considers the original purchase price and the vehicle's age. It does not account for mileage, condition, market trends, or model-specific differences, as stated in its description.
Is this calculator accurate for my specific car?
No, it provides a general educational estimate. Actual vehicle value can vary significantly based on many factors not included here, such as maintenance, accidents, and local demand. Use it as a rough guide, not a precise valuation.

Tips & Common Mistakes

Tips

  • Enter the exact purchase price you paid, including taxes and fees, for a more realistic estimate.
  • Use the vehicle's age in years from the date of purchase to the current date.
  • Remember that this is a simplified model; real-world values can be higher or lower.
  • For a more accurate valuation, consult professional sources like Kelley Blue Book or local listings.

Common Mistakes to Avoid

  • Assuming the estimate is exact and not considering other factors like mileage or condition.
  • Using the current market value instead of the original purchase price.
  • Entering the age in months instead of years, which can skew the result.
