Car Depreciation Calculator

Vehicle depreciation is the loss of value that occurs from the moment a car is driven off a dealer lot through the end of its economic life. It is the single largest cost of car ownership over a typical ownership period — larger than fuel, insurance, and maintenance combined for most mainstream vehicles.

Depreciation is not linear. The steepest drop happens in year one, when the vehicle transitions from "new" status to "used" status. Regardless of miles or condition, the change in title designation alone drops the resale value by 20-30% for most mainstream models. Years 2-5 depreciate more gradually at roughly 15% per year of the prior year's value. After year 5 the curve flattens further — most vehicles lose 5-10% per year through year 10, and even less after that.

The specific rate depends heavily on the make, model, and trim. Toyota, Honda, and Subaru consistently lead in resale value retention; European luxury brands (Mercedes-Benz, BMW, Audi) tend to depreciate the fastest; American full-size trucks (Ford F-150, Chevrolet Silverado) hold value well because of steady commercial and consumer demand. Kelley Blue Book and iSeeCars publish annual rankings that identify the best and worst depreciators in each vehicle class.

The 20-30% first-year drop is partly rational and partly psychological. Rationally, a new car's price includes several non-transferable components: dealer profit margin, manufacturer-to-dealer promotional payments, financing incentives, and the aggregated marketing costs baked into MSRP. When the vehicle changes hands to a private buyer, all of that value is gone — the second buyer pays for the vehicle, not the marketing.

Psychologically, the "used" designation triggers immediate discount expectations from every downstream buyer. A used-car shopper actively wants a bargain, and the market rewards that expectation with a fresh price anchor. This is why nearly-new certified pre-owned (CPO) vehicles at 12-18 months old are one of the sweet spots for value — the buyer captures the first-year depreciation as a discount but still gets a nearly-new vehicle with warranty.

The exception to the first-year rule is limited-production or aspirational-brand vehicles (Porsche 911, Toyota Land Cruiser, some Jeep Wrangler trims), which can hold or even gain value in year one when demand exceeds production capacity. These are outliers and cannot be reliably predicted; assume standard depreciation for planning.

iSeeCars's annual depreciation study consistently identifies the best and worst holders of value across mainstream US market segments. Recent findings show these representative 5-year depreciation ranges:

Several factors depreciate a specific vehicle faster than the class average would predict. Higher-than-average mileage (20,000+ miles per year) can subtract 5-10% from expected resale value. Accident history — even a single moderate incident recorded on Carfax — commonly reduces resale value by 10-15%. Cosmetic damage, aftermarket modifications away from stock, and pet or smoke odour further reduce buyer appeal.

Colour matters more than most buyers expect. Neutral colours (white, black, silver, grey) sell fastest and hold value best. Bright or unusual colours (bright red, orange, yellow, purple) can subtract 5-10% at resale because the buyer pool is smaller. Tesla Model 3 buyers who chose "Multi-Coat Red" or "Deep Blue Metallic" often find that resale takes longer and requires more discount than the plain white version.

Reliability matters enormously. Vehicles with above-average recall counts or known-issue histories (transmission failures, timing chain problems, expensive infotainment issues) all depreciate faster because the used-car market prices in the expected repair costs. Consumer Reports' predicted reliability rankings correlate strongly with 5-year depreciation curves.

Vehicle leases are structured around depreciation. The monthly lease payment is essentially the vehicle's expected depreciation during the lease term, plus a "money factor" (the lease equivalent of an interest rate) and lease fees, divided by the number of months. A 3-year lease on a $40,000 vehicle expected to be worth $24,000 at lease-end has $16,000 of depreciation to be recovered over 36 months = ~$444/month before money factor and taxes.

This is why vehicles that depreciate slowly (Toyotas, Hondas) often have less attractive lease deals than vehicles that depreciate quickly (BMWs, Mercedes) — the lease payment on the slow depreciator is a larger fraction of the vehicle's residual value, so the "monthly cost divided by MSRP" ratio is worse.

Conversely, luxury vehicles often lease at surprisingly attractive rates for the same reason: high depreciation forces a lower residual value, which gets baked into the lease as a lower monthly payment. The catch is that leasing a fast-depreciator turns depreciation into a fixed monthly cost you pay throughout the lease, whereas buying the same vehicle and holding it 8-10 years amortises depreciation over more years.

The steepest phase of the depreciation curve is complete by year 3-4. A vehicle purchased at that age captures 50-60% of the original MSRP as a discount, while typically having 60,000+ miles of useful life remaining. On a rate-per-mile basis, this is often the lowest-cost car ownership approach available.

The trade-off is warranty exposure. New vehicles typically ship with 3-year / 36,000-mile bumper-to-bumper warranties and 5-year / 60,000-mile powertrain warranties. A vehicle purchased at 3-4 years old is largely out of bumper-to-bumper warranty and near the end of the powertrain warranty, so any major mechanical failure falls on the owner.

Certified Pre-Owned (CPO) programs from manufacturers extend the warranty on carefully-inspected used vehicles, typically for an additional 1-2 years. CPO cars command a 5-10% price premium over comparable non-CPO used cars — often worth it for peace of mind, especially on brands with expensive repairs (European luxury, complex hybrids).

Depreciation is one component of total cost of ownership (TCO). The full picture includes purchase-price depreciation, financing cost, insurance, fuel, maintenance, repairs, taxes and fees, and any state-level ownership taxes (personal property tax in some states like Virginia and Missouri).

Kelley Blue Book publishes a "5-Year Cost to Own" metric that captures this holistic view. For most mainstream vehicles, depreciation is 40-50% of 5-year TCO, fuel is 20-25%, insurance is 15-20%, maintenance and repairs are 8-12%, and financing is 5-10%. Understanding this breakdown helps choose vehicles that optimise across all cost dimensions, not just purchase price.

A relatively cheap-to-buy vehicle with high fuel cost, high insurance, and reliability issues (some older luxury imports fall into this bucket) can have a higher 5-year TCO than a more expensive-to-buy but efficient-and-reliable alternative. Always look at TCO, not just purchase price.

For business-use vehicles, depreciation becomes tax-deductible under IRS Section 179 and MACRS rules (Publication 946). A qualifying vehicle used more than 50% for business can be depreciated over 5 years under the Modified Accelerated Cost Recovery System, generally providing larger deductions in earlier years.

Section 179 additionally allows immediate first-year expense of much of the vehicle cost for qualifying vehicles (particularly SUVs and trucks over 6,000 lbs gross vehicle weight rating), subject to annual expense limits ($1.16M total Section 179 for 2026, subject to phase-out over $2.89M in total qualifying property). This is why business owners frequently choose large SUVs — the immediate tax deduction often offsets a substantial fraction of the purchase cost.

For business-use vehicles below the 6,000-lb threshold, the "luxury auto" depreciation cap under Section 280F limits annual deductions to specific dollar amounts (roughly $12,200 first year with bonus depreciation, dropping in subsequent years). Higher-priced passenger vehicles used for business are effectively cost-capped for tax purposes.

Buy a slow-depreciating model. The 5-year depreciation gap between the best and worst holders in the same segment is often 20-25 percentage points — huge in absolute dollars. Kelley Blue Book's annual Best Resale Value Awards is the standard reference.

Buy 2-4 year old CPO. Skip the steep first-year drop entirely, still get warranty coverage, save 40-50% on purchase price.

Keep the vehicle 8-10 years. The depreciation curve flattens after year 5. If you buy new and hold to year 10, your annual depreciation cost per year is much lower than if you swap every 3-4 years and repeatedly buy new.

Preserve resale-critical items. Maintain service records (Carfax reads service history), avoid smoking or letting pets in the cabin, address cosmetic damage promptly, keep the vehicle in a garage where possible. These maintain the top-of-market resale price for your vehicle at any given age.

Sell privately, not to a dealer. Trade-in values run 10-20% below private-party values. Selling on Carvana, Vroom, or through a private listing captures the private-party price, which can be a $2,000-4,000 difference on a $20,000 used vehicle.
