Car Depreciation Rate Calculator: Value Lost Between Two Years
Work out how much value a car has lost since purchase — the depreciation that's often the largest cost of ownership and the most-overlooked line item on the household budget.

Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Total depreciation | Dollar value lost |
|---|---|---|
| $30k to $24k (20% loss) | -20.00% | -6,000 |
| $45k to $30k | -33.33% | -15,000 |
| $18k to $14k | -22.22% | -4,000 |
| $80k to $35k (luxury depreciation) | -56.25% | -45,000 |
How This Calculator Works
Enter the purchase price and the current market value. The calculator subtracts one from the other for the dollar value lost and divides by the purchase price for the depreciation rate. The result covers the full ownership period; divide by years held for an average annual rate.
The Formula
Percentage Change
Old is the starting value, New is the ending value
Worked Example
A $30,000 car worth $24,000 today has depreciated $6,000 — a 20% loss in value. If the car is two years old, that averages about 10% per year — close to the long-term industry average. New cars typically lose 20% in year one alone; the curve flattens in later years.
Key Insight
Car depreciation is the largest hidden cost of ownership for most households — often exceeding gas, maintenance, and insurance combined. New cars lose 20%+ in year one and 40% to 50% over five years; buying a 2- to 3-year-old used car captures most of the value depreciation without absorbing it yourself. The cars that hold value best are typically Toyota, Honda, and Subaru in tighter-supply trims; luxury European cars typically depreciate fastest.
Frequently Asked Questions
How is car depreciation calculated?
Subtract current value from purchase price, divide by purchase price, multiply by 100. A $30,000 car now worth $24,000 has depreciated 20%.
What is a typical car depreciation rate?
New cars: 20%+ in year one, 40% to 50% over 5 years, 60%+ over 10 years. Used cars depreciate more slowly because the steepest drop has already happened. Long-term industry average is roughly 10% to 15% per year for new cars across the first 5 years.
Which cars hold value best?
Generally Toyota, Honda, Subaru, and Porsche in popular trims. Models with strong resale (Tacoma, 4Runner, Wrangler, certain Lexus models) routinely retain 60%+ after 5 years. Luxury European brands and EVs (early models) often depreciate fastest.
Should I buy new or used?
Used (2 to 4 years old) almost always wins on lifetime cost — the original owner absorbs the steep first-year depreciation. Exceptions: certain manufacturer-incentive deals on new vehicles, or models with severe used-market supply constraints.
Does EV depreciation differ from gas cars?
Yes — historically faster, especially for older EVs (Nissan Leaf, early Tesla Model S) where battery degradation and improving newer models compressed used prices. Newer EVs with longer range are holding value better; the gap is narrowing.

Methodology & Review
Depreciation is current value minus purchase price, divided by purchase price. A negative result is depreciation (value lost); positive means appreciation. The figure covers the full ownership period; annualize by dividing by years held for an average annual rate.
