About this calculator

Estimate how much a car's value drops each year and what it might be worth after a given number of years.

Vehicles typically lose value fastest in the first few years and more slowly after — a pattern approximated here with declining-balance depreciation, where the same percentage is applied to the remaining value each year (rather than a flat dollar amount every year). Actual resale value depends heavily on make, model, mileage, condition, and market demand, so treat this as a planning estimate rather than an appraisal.

How to use

  1. Enter the purchase price.
  2. Enter the number of years to project.
  3. Enter (or accept the default) annual depreciation rate.
  4. Press Calculate to see the estimated value, total depreciation, and a year-by-year breakdown.

Tips

  • New cars typically lose around 20% of their value in the first year alone — buying a 1-2 year old used car can avoid the steepest part of the depreciation curve.

Formula

Value after n years = Purchase Price × (1 − Depreciation Rate)ⁿ
