Car Depreciation Calculator

Vehicle depreciation follows a declining-balance curve where the value drops fastest in the first year and slows over time. The standard industry model uses approximately 15% in years 1-2, 12% in year 3, 10% in year 4, and 9% in year 5. Enter the purchase price, number of years, and a depreciation method to see the estimated value and a year-by-year breakdown table.

Quick Answer

A $35,000 vehicle using standard depreciation rates is estimated to be worth approximately $20,089 after 3 years, losing approximately $14,911 (42.6% of its original value).

How It Works

The Formulas

Standard (Industry Curve) Method:

This method uses rates derived from industry depreciation averages. The vehicle loses a percentage of its current (not original) value each year:

  • Year 1: 15%
  • Year 2: 15%
  • Year 3: 12%
  • Year 4: 10%
  • Year 5: 9%
  • Year 6+: 7% per year

Value after Year N = Previous Year Value x (1 - Rate for Year N)

Straight-Line Method:

The vehicle depreciates by an equal dollar amount each year, assuming a 10-year useful life:

Annual Depreciation = Purchase Price / 10

Value after Year N = Purchase Price - (Annual Depreciation x N)

This method is simpler but less realistic for vehicles, which lose more value in early years.

Custom Rate Method:

The vehicle loses a fixed percentage of its current value each year:

Value after Year N = Purchase Price x (1 - Custom Rate / 100)^N

This is a declining-balance method identical to the standard method but with a uniform rate.

What Affects Vehicle Depreciation

Several factors influence how quickly a vehicle depreciates: brand reputation and reliability, mileage, condition, market demand, fuel type, vehicle type (trucks hold value better than sedans on average), and overall economic conditions. Electric vehicles have seen varying depreciation patterns as the market evolves.

Average Depreciation Benchmarks

Industry data suggests a new vehicle loses approximately 20% to 25% of its value in the first year, 35% to 45% over three years, and 50% to 60% over five years. These are averages, and individual vehicles may depreciate faster or slower.

Worked Example

For a $35,000 vehicle using the standard method over 3 years: Year 1: $35,000 x 0.15 = $5,250 depreciation. Value = $35,000 - $5,250 = $29,750. Year 2: $29,750 x 0.15 = $4,463 depreciation. Value = $29,750 - $4,463 = $25,288. Year 3: $25,288 x 0.12 = $3,035 depreciation. Value = $25,288 - $3,035 = $22,253. Total depreciation = $35,000 - $22,253 = $12,747 (36.4%). The vehicle retains approximately 63.6% of its original value after 3 years.

Frequently Asked Questions

Which depreciation method is most accurate for cars?
The standard (industry curve) method most closely reflects real-world vehicle depreciation, where the steepest losses occur in the first two years. Straight-line is simpler but less realistic. The custom rate option allows adjusting for vehicles that hold value particularly well or poorly.
Do all cars depreciate at the same rate?
No. Depreciation varies significantly by make, model, and market conditions. Trucks and SUVs from brands known for reliability tend to depreciate more slowly, while luxury vehicles and high-volume sedans often depreciate faster. Check recent resale data for your specific vehicle to refine the estimate.
How does mileage affect depreciation?
Higher mileage generally accelerates depreciation. The average driver puts approximately 12,000 to 15,000 miles per year on a vehicle. Vehicles with significantly higher mileage lose value faster, while low-mileage vehicles may hold value better than these estimates suggest.
What is the difference between depreciation and resale value?
Depreciation is the loss in value from the original purchase price. Resale value is the estimated amount the vehicle could sell for at a given point in time. Resale value = Purchase Price - Total Depreciation. Actual resale prices also depend on condition, mileage, local market, and current demand.
Do electric vehicles depreciate differently?
Electric vehicle depreciation patterns are evolving. Some early EVs depreciated quickly due to battery concerns and limited demand. Newer EVs from popular brands may hold value better as the market matures and charging infrastructure expands. Battery degradation, technology updates, and government incentives all influence EV resale values.
