Your car loses $7,000 in the first year alone — 20% of its purchase price. Over 10 years it depreciates $28,515, ending at $6,485 (about $238/month in lost value).

What is the car depreciation calculator?

In short

Cars typically lose 15–25% of their value in the first year and roughly 10–15% of their remaining value each year after that. A $35,000 new car loses about $7,000 (20%) in year one, is worth roughly $14,600 after 5 years, and only about $6,500 after 10 years — a total depreciation of about $28,500, or nearly $240 per month of ownership.

This car depreciation calculator projects your vehicle's value year by year using a first-year depreciation rate and a subsequent annual rate, both adjustable. It shows the value at the end of your ownership period, total depreciation, and the average cost per year and per month — usually the largest hidden cost of car ownership.

How to use this calculator

  1. 1Enter the car's purchase price when new.
  2. 2Enter the vehicle's current age (0 for a brand-new car).
  3. 3Set how many years you plan to own it.
  4. 4Adjust the first-year depreciation rate (typically 15–25%) and the annual rate after that (10–15%).
  5. 5Review the value curve, total depreciation, and monthly cost of depreciation.

The formula

V=P×(1d₁)×(1d)t1
Value after t years = Purchase Price × (1 − first-year rate) × (1 − annual rate)^(t − 1). Depreciation compounds on the remaining value, so dollar losses are biggest in the early years.
V
Vehicle value after t years
P
Original purchase price
d₁
First-year depreciation rate
d
Annual depreciation rate in later years
t
Vehicle age in years

Worked example

The scenario

A $35,000 new car with 20% first-year depreciation and 15% annual depreciation thereafter, owned for 10 years.

gives

The result

Year 1 value: $28,000 (a $7,000 loss). Year 5: about $14,600. Year 10: about $6,500. Total depreciation over 10 years: roughly $28,500 — about $2,850/year or $237/month.

Common use cases

  • Estimating your car's future trade-in or resale value before buying
  • Comparing the true cost of buying new versus a 2–3 year old used car
  • Budgeting the real monthly cost of ownership (depreciation often exceeds fuel)
  • Deciding the optimal time to sell before value flattens out
  • Checking whether you risk being underwater on a low-down-payment car loan

Limitations & assumptions

  • Real depreciation varies widely by brand, model, mileage, condition, and market — trucks and Toyotas hold value far better than luxury sedans and EVs.
  • Used-market shocks (like 2021–22, when used prices rose) can temporarily break the curve.
  • Mileage is not modeled directly; high-mileage cars depreciate faster than the age curve implies.
  • Does not include other ownership costs such as insurance, maintenance, fuel, or financing interest.

Frequently asked questions

A typical new car loses about 20% of its value in the first year and 10–15% of its remaining value each year after. A $35,000 car drops to about $28,000 after year one, $24,000 after year two, and roughly $14,600 by year five — around 58% total depreciation in five years. By year ten it's often worth less than 20% of its original price.
