Vehicle Depreciation Calculator (Year-by-Year Value Curve)
LiveVehicle depreciation is the single largest cost of car ownership for most people, typically dwarfing fuel, maintenance, and insurance combined. A new car loses 15 to 25 percent of its value in the first year alone, then declines at a slower steady pace for the next several years before tailing off in the later years. The shape of the curve depends heavily on the brand, model, condition, and mileage.
This calculator takes the purchase price and three depreciation rates (year 1, years 2 through 5, and year 6 onward) and projects the year-by-year value of the vehicle through your planned ownership period. It returns the estimated value at the end of ownership, the total depreciation over the period, the average annual depreciation expense, and the year-by-year value table.
A rough sanity check: a $40,000 mainstream sedan with typical depreciation rates (20 percent year 1, 15 percent years 2-5, 10 percent years 6+) is worth about $19,500 at year 5 and $13,500 at year 7. Total depreciation over 7 years is roughly $26,500, or about $3,800 per year on average. The first year alone is responsible for $8,000 of the total, illustrating why buying a 1-year-old used vehicle is one of the most reliable ways to reduce total cost of ownership.
Depreciation rates vary significantly by category. Toyota and Honda mainstream models depreciate slower than the calculator's defaults (closer to 15/12/8 percent). Luxury brands (most German and some Japanese luxury) depreciate faster (25/18/12 percent). Trucks and some SUVs hold value remarkably well (10/10/8 percent). Lower-volume models (orphan cars, certain manual-transmission variants, niche brands) depreciate fastest of all. Look up the specific model's residual-value forecast on Kelley Blue Book or Edmunds to refine the rates for a particular vehicle.
Why year 1 depreciation is so steep
The new-car premium captures three things: the difference between a new and used title (the same car loses 5 to 10 percent of value the moment it leaves the dealer's lot just from the title change), the unwound dealer profit margins and incentives, and an initial year of typical mileage and wear. Combined, the first-year drop on a typical mainstream vehicle is 15 to 25 percent of the original MSRP. Luxury vehicles and lower-volume models often drop 25 to 35 percent in year one.
This is why buying 1 to 2 year-old used vehicles is one of the most reliable ways to reduce total cost of ownership. You let the original buyer absorb the steep year-1 depreciation; you pick up the vehicle at a meaningful discount; and you still have most of the useful life ahead. Certified pre-owned (CPO) programs offer additional warranty coverage on these slightly-used vehicles, removing some of the risk of buying used.
What slows depreciation
Four factors slow depreciation meaningfully. First, brand reputation for reliability and longevity. Toyota and Honda are at the top of mainstream reliability rankings and consistently retain value better than competitors. Subaru, Mazda, and certain Hyundai/Kia models have closed the gap in recent years.
Second, mileage. The 12,000-mile-per-year average is the baseline; vehicles with significantly higher mileage (heavy commuters, ride-share drivers) lose value faster than the calculator's curve, sometimes by 3 to 5 percent per year. Vehicles with low mileage (under 8,000 per year) command a premium and depreciate slower.
Third, condition and accident history. A clean Carfax report and excellent condition is worth 10 to 20 percent more than a comparable vehicle with minor accident history or visible wear. Salvage titles destroy value almost entirely; flood damage can permanently mark a vehicle.
Fourth, body style and demand. Pickups (especially full-size from Toyota and Ford) and certain SUVs hold value remarkably well due to high demand and limited supply. Sedans and minivans depreciate faster than crossovers and SUVs in the current market.
How to use this calculator for cost-of-ownership planning
Depreciation is one component of total cost of ownership. To get a complete picture, run this calculator for the depreciation expense, then add fuel, insurance, maintenance, and registration fees. A typical $40,000 vehicle owned for 7 years at 12,000 miles per year costs roughly $26,500 in depreciation, $4,000 in fuel ($3,200 if EV), $9,000 in insurance ($1,300/year), $4,500 in maintenance, and $1,000 in registration: about $45,000 total cost of ownership, or $0.54 per mile.
For true cost-of-ownership comparison between vehicles, depreciation often dominates the other components. Choosing a slow-depreciating model (Toyota, Honda) versus a fast-depreciating one (typical European luxury) can save $10,000 to $20,000 over 7 years even on similarly-priced vehicles.
Selling timing
Many owners find the sweet spot for selling is years 4 to 6: depreciation has slowed from the steep first year, the vehicle is still under or near the original 5-year warranty, and major repairs (timing belt, transmission service) have not yet hit. Owners who hold longer (10+ years) experience much lower annual depreciation but higher maintenance and the eventual need for major repairs.
If you plan to drive a vehicle into the ground (200,000+ miles), depreciation almost stops mattering; the vehicle is worth almost nothing at the end and you have squeezed maximum value from the original purchase. This is the most economical ownership pattern but requires tolerance for maintenance and the gradual loss of new-car features.
What this calculator does not include
Mileage variation from the 12,000-per-year baseline (heavy use accelerates depreciation; light use slows it). Accident or damage history. Mods and aftermarket changes (typically reduce resale value even when they improve the vehicle's performance). Market conditions (the used-car market spiked dramatically in 2021-2022 and depreciation curves were temporarily disrupted; current conditions are more normal). Specific model residual-value forecasts (look up your model on Kelley Blue Book or Edmunds for refined estimates). Total cost of ownership beyond depreciation (fuel, insurance, maintenance, registration). For a complete TCO model, run this calculator for depreciation and add other ownership costs separately.
Frequently asked questions
Defaults of 20/15/10 percent (year 1, years 2-5, years 6+) match a typical mainstream mid-size sedan. Toyota and Honda models are slower (15/12/8). Luxury and lower-volume models are faster (25/18/12). Pickups and certain SUVs are slowest of all (10/10/8). Look up the specific model's residual-value forecast on Kelley Blue Book or Edmunds to refine the rates.
