Car Depreciation Calculator
Calculate your vehicle's depreciation over time using straight-line or declining balance methods. See a year-by-year breakdown of your car's estimated value and total depreciation.
Depreciation is the largest cost of car ownership for most drivers — typically more than fuel, insurance, and maintenance combined over a vehicle's lifetime. A new car loses 20-30% of its value the moment you drive it off the lot, then continues losing roughly 15% per year for the next four years. By year five, most vehicles retain only 40-50% of their original MSRP. This silent cost shapes whether buying new or used makes financial sense, when to sell, and how leasing vs. buying compares.
Depreciation rates vary substantially by make, model, and category. Luxury sedans and German marques (BMW, Mercedes) historically depreciate fastest (60-70% loss in 5 years). Toyota, Honda, and Lexus depreciate slowest (often retaining 55-65% after 5 years). Trucks and SUVs typically depreciate slower than sedans due to durability and demand. EVs have historically depreciated rapidly due to battery degradation concerns and rapid technology improvements, though this is moderating. Specific models can buck trends — limited-edition sports cars, Wranglers, and 4Runners sometimes hold value exceptionally well.
This calculator models depreciation using either declining balance (more realistic — applies the percentage to the remaining value each year, producing front-loaded loss) or straight-line (fixed dollar amount per year, simpler but unrealistic). Use it to: project resale value at planned sale date, understand the true cost of new-vehicle purchase vs. used, model lease residuals, and inform "buy and hold" vs. "buy and trade" strategies. The financial case is consistent: buying 3-5 year-old vehicles and holding 7-10 years captures the lowest depreciation cost per year, while buying new and trading every 3-4 years captures the most.

Formula
How to use this calculator
- Enter purchase price (paid, including taxes and fees if you want total cost basis; otherwise just sticker price).
- Enter number of years you plan to model.
- Enter annual depreciation rate (15% is a typical average; 20-25% for first year of new vehicles; 10-12% for trucks/SUVs).
- Select method: declining balance (more realistic for vehicles) or straight-line (simpler).
- Review year-by-year value projection.
- For specific make/model: check Kelley Blue Book (kbb.com) or NADA Guides historical depreciation data for that vehicle.
- Use the result to: assess buy-vs-lease (lease residuals are essentially predicted depreciation), plan optimal sell date, compare new vs. used purchase economics, and understand the "true cost" of vehicle ownership.
- For tax purposes (business vehicles): use IRS-mandated MACRS depreciation tables, not this calculator. This is for personal financial planning only.
Worked examples
New luxury sedan — fast depreciation
$60,000 BMW 5-Series, 20% annual depreciation (faster than average for luxury). Year 1: $48,000 (lost $12,000) Year 3: $30,720 (lost $29,280 total) Year 5: $19,660 (lost $40,340 total — 67% loss) Annual depreciation cost: ~$8,000/year average. This is why luxury cars are most economical when purchased used — let the original buyer absorb the first 50% of depreciation. Strategy: buying a 3-year-old BMW 5-Series for $30K (vs. $60K new) and holding 7 more years captures only the moderating-rate years of depreciation. Much better economics.
Toyota Tacoma — slow depreciation
$35,000 Toyota Tacoma, 8% annual depreciation (very slow — Tacomas are legendary for holding value). Year 1: $32,200 (lost $2,800) Year 5: $23,000 (lost $12,000 — only 34% loss) Year 10: $15,100 (lost $19,900 — 57% loss over a decade) Annual depreciation: ~$2,400/year first 5 years, ~$1,600/year next 5. Much lower total cost than typical. Tacomas (and Wranglers, 4Runners, certain Honda models) are unusual — limited supply, strong used demand, and durability create exceptional resale value. Buying these "new" makes more sense than for most vehicles because the depreciation gap vs. used isn't as wide.
Used-car sweet spot
Comparing $35K new vs. $22K used (same model, 3 years old). Plan to keep 7 years. New purchase: $35K → ~$15K after 7 more years = $20K depreciation. Plus $35K initial outlay (financing costs). Used purchase: $22K → ~$10K after 7 more years (already depreciated, slower curve from here) = $12K additional depreciation. Initial outlay $22K. Used saves: $13K initial + $8K depreciation = $21K total savings over 7 years. Used-car downsides: no manufacturer warranty (extended warranty optional), unknown wear/maintenance history, potentially older safety/tech. For most buyers in good financial situations, this 60% cost reduction justifies those tradeoffs. The "buy used, drive 7-10 years" strategy is the most economical car ownership pattern available. Annual depreciation cost can drop to $1,500-$2,500/year vs. $4,000-$6,000/year for new.
When to use this calculator
Use this calculator when planning a vehicle purchase, estimating resale value at planned sale date, comparing new vs. used purchase economics, modeling lease vs. buy decisions, or assessing the true cost of car ownership.
Pair with auto-loan (financing costs), lease-vs-buy (long-term comparison), and car-loan-payoff (early payoff scenarios).
Important depreciation considerations:
1. **Depreciation typically dominates total cost.** For most vehicles, depreciation ($3K-$6K/year) exceeds fuel, insurance, and maintenance combined. Buyers focusing on monthly payment often underestimate this hidden cost.
2. **First-year cliff is real.** A new car loses 20-30% in year 1 alone. The "driving off the lot" loss is sometimes overstated but the first-year depreciation is genuinely steep.
3. **Used 3-5 year-old vehicles capture the best economics.** The original buyer absorbs the steepest depreciation. By year 3-5, the curve flattens substantially. Buying used and holding 7-10 years can halve annual depreciation cost.
4. **Vehicle category matters enormously.** Trucks and certain SUVs depreciate at 8-12%/year. Luxury sedans depreciate at 18-22%/year. Choose category based on resale value if you trade frequently; choose based on need if you keep long-term.
5. **EV depreciation is changing rapidly.** Earlier EVs (pre-2018) depreciated very fast (battery concerns + technology improvements). Newer EVs (Tesla, modern BEVs) are depreciating closer to ICE vehicle norms. Battery health certifications now being introduced should stabilize values further.
6. **Limited editions and enthusiast vehicles can hold value.** Wranglers, certain 4x4s, sports cars, and limited-production models sometimes appreciate or hold value exceptionally well. Researching the specific vehicle's historical depreciation is more useful than category averages.
7. **Tax depreciation is different from market depreciation.** This calculator estimates market value over time. For business vehicles, the IRS prescribes specific depreciation schedules (MACRS, Section 179, bonus depreciation) — see a tax professional for that.
8. **Mileage affects depreciation.** Higher than average mileage (12K-15K/year for typical use) accelerates depreciation; lower mileage slows it. A 5-year-old vehicle with 35K miles is worth substantially more than the same vehicle with 90K miles.
9. **Condition and maintenance matter.** Well-maintained vehicles with service records, no accidents, and clean interiors retain value significantly better than worn/damaged ones. Investing in maintenance partially pays back via higher resale value.
10. **Buy-and-hold beats buy-and-trade financially.** Owning a vehicle 10+ years captures the moderating-rate later years when annual depreciation is smaller. Trading every 3-4 years means constantly absorbing the steepest depreciation years.
Common mistakes to avoid
- Focusing on monthly payment instead of total cost. Depreciation is often the largest ownership cost and is invisible in the monthly bill.
- Buying new luxury sedans for "value." Luxury sedans are among the worst-depreciating categories. Buy them used (3-5 years old) for dramatic savings.
- Ignoring vehicle-specific depreciation. Category averages mask wide variation. Research specific make/model historical depreciation before purchase.
- Assuming straight-line depreciation. Real-world car depreciation is front-loaded (declining balance). Straight-line underestimates first-year loss and overestimates later-year loss.
- Forgetting depreciation when comparing buy vs. lease. Lease payments reflect predicted depreciation. Compare lease vs. buy on total cost over multiple ownership cycles.
- Not accounting for mileage in resale estimates. High-mileage vehicles depreciate faster than calculator estimates assume. Adjust expectations if driving 15K+ miles/year.
