What this calculator does
The Car Depreciation Calculator estimates how a vehicle's value may decline over time from an initial purchase price and assumed depreciation pattern.
How to use the calculator step by step
Enter the original vehicle value, age or holding period, and depreciation rate assumptions shown by the page. Use realistic resale values when possible rather than assuming every vehicle follows the same percentage decline.
How the calculation works
A simple depreciation model reduces vehicle value by a percentage over time. Some models use a fixed annual percentage while others apply a larger decline in early years and smaller declines later.
Worked example and scenario testing
A vehicle purchased for 30,000 that loses 20% in the first year would be estimated at 24,000 after that year under a simple percentage model.
How to interpret your result
The result is a planning estimate of resale value. Real depreciation depends on brand, mileage, condition, accident history, market demand, maintenance, and local pricing.
Accuracy, assumptions, and limitations
Vehicle values can move differently from a smooth mathematical curve. Used-car market shifts, supply shortages, recalls, and unusually high or low mileage can materially change resale value.
Common mistakes to avoid
Do not assume the same depreciation rate applies every year or every vehicle model. Also avoid confusing accounting depreciation with actual market resale value.
