Car Depreciation Calculator estimates how a vehicle loses value over time, projecting its worth year by year from the purchase price, the years owned, and an expected depreciation rate — so you can see the biggest, most overlooked cost of car ownership.
Depreciation is front-loaded. A new car typically sheds roughly 15–20% in the first year and around half its value over five years, with the sharpest drop happening immediately as it becomes 'used'. After that, the percentage decline eases. This curve is exactly why a one-to-three-year-old car often offers far better value than new.
The estimate is a projection, not a valuation: real resale value hinges on mileage, condition, service history, model desirability, and the market when you sell. So choose a rate that fits the specific vehicle and treat the output as a planning guide rather than a guaranteed price.
Because depreciation is essentially the price of ownership over time, it's central to buy-vs-lease and resale-timing decisions — a car that holds value well is cheaper to own. Everything runs in your browser, so your figures stay private. Pair it with the other ToolsMonk automobile and finance tools to model the full cost of running a vehicle.
Buying a 1–3 year old car sidesteps the steepest first-year depreciation while still getting a modern vehicle
Compare models on how well they hold value, not just sticker price — depreciation is often the biggest ownership cost
Treat the result as a planning estimate; mileage and condition swing real resale value significantly
