A car is a depreciating asset, it loses value the moment you drive it off the lot and continues to decline with age and mileage. Understanding how much value your vehicle will lose helps you make smarter decisions about buying, selling, and holding onto a car. This Car Depreciation Calculator models four depreciation patterns: Standard, Aggressive, Conservative, and Custom. It uses your purchase price, current age, annual mileage, and projection period to generate a detailed schedule of value over time. You’ll see the current value, total loss, percentage retained, and the projected value at the end of your chosen period. The calculator supports 22 currencies and includes a year-by-year table and a visual depreciation curve. All calculations run in your browser, keeping your financial data private.

How the Car Depreciation Calculator Formula Works
The calculator builds a depreciation schedule from year 0 to the end of the projection period.
Year 1 Depreciation:
Year 1 Value = Purchase Price × (1 − First-Year Rate)
Subsequent Years:
Value(t) = Value(t−1) × (1 − Subsequent Rate)
Floor: The value never drops below 5% of the original purchase price.
Depreciation Method Rates:
Standard: 20% year 1, then 15% per year
Aggressive: 25% year 1, then 18% per year
Conservative: 15% year 1, then 10% per year
Custom: user-defined first-year rate, then 75% of that rate for subsequent years
Current Value:
If the car age is a whole number, the value is taken directly from the schedule. If fractional, the calculator interpolates linearly between the two nearest years.
Metrics:
Total Depreciation: Purchase Price − Current Value
Value Retained: (Current Value ÷ Purchase Price) × 100
End Value: Value at the end of the projection period
Worked Example
A buyer purchases a new car for $35,000 and wants to see its value after 5 years using the Standard depreciation method.
Step 1 – Build the depreciation schedule:
Year 0: $35,000
Year 1: $35,000 × (1 − 0.20) = $28,000
Year 2: $28,000 × (1 − 0.15) = $23,800
Year 3: $23,800 × (1 − 0.15) = $20,230
Year 4: $20,230 × (1 − 0.15) = $17,196
Year 5: $17,196 × (1 − 0.15) = $14,616
Step 2 – Current value after 5 years:
$14,616
Step 3 – Total depreciation:
$35,000 − $14,616 = $20,384
Step 4 – Value retained:
($14,616 ÷ $35,000) × 100 = 41.8%
Step 5 – Classification:
Standard depreciation, typical for mainstream sedans and SUVs. The biggest loss happens in year 1: $7,000 (20%).
Interpretation:
“Purchase price: $35,000. After 5 years (standard method), the car is worth $14,616, a total depreciation of $20,384 (58.2%). By year 10, the value will be approximately $6,257 (17.9% of original). Your car has retained 41.8% of its value.”
Frequently Asked Questions
What is the Car Depreciation Calculator and how does it work?
The Car Depreciation Calculator estimates how much a vehicle will be worth over time. It uses your purchase price, car age, and projection period to build a year-by-year depreciation schedule based on the method you select. It then reports current value, total depreciation, value retained, and projected end value.
How much does a car depreciate per year?
A typical new car depreciates about 20% in the first year and around 15% per year after that. By year 5, it usually retains 35–45% of its original value. Actual rates vary by brand, model, mileage, and market conditions.
What is the difference between Standard, Aggressive, and Conservative depreciation?
Standard uses 20% year 1 and 15% thereafter. Aggressive uses 25% year 1 and 18% thereafter. Conservative uses 15% year 1 and 10% thereafter. Choose the method that best matches your vehicle’s expected value retention.
Can I use a custom depreciation rate?
Yes. Select the Custom method and enter your own first-year depreciation rate. The calculator uses 75% of that rate for subsequent years.
What is the 5% floor in the calculator?
The calculator prevents the car’s value from dropping below 5% of the original purchase price. This reflects the reality that most vehicles retain a minimum scrap or residual value.
How does mileage affect depreciation?
Higher annual mileage accelerates depreciation because buyers pay less for high-mileage cars. While the calculator does not directly use mileage in its formula, you can account for it by choosing a more aggressive method or adjusting your custom rate.
Which cars hold their value best?
Reliable, high-demand models from brands like Toyota, Honda, and Subaru tend to hold value best. Trucks and some SUVs also retain value well. Luxury sedans and niche EVs often depreciate faster.
Is the Car Depreciation Calculator free?
Yes, it is completely free and runs in your browser. No registration or data submission is required.
Can I use this calculator for a lease decision?
Yes. By comparing the projected value at the end of the lease term with the residual value in the lease contract, you can judge whether the lease is fairly priced.
Does the calculator account for inflation?
No. The calculator shows nominal values — the actual dollar amounts at each future year. Inflation would reduce purchasing power but is not directly modeled here.
