Car Depreciation Calculator
Calculate annual depreciation, total cost of ownership, and resale value projections
Standard: 12,000/year. High: 20,000+
Supply/demand: +10% shortage, -10% surplus
What Is Car Depreciation?
Car depreciation is the difference between what you paid for your car and what it is worth today.
For example:
- You buy a car for $35,000.
- After 5 years, it is worth $18,000.
- You lost $17,000 in value.
That $17,000 is depreciation.
Most cars lose value every year. The biggest drop usually happens in the first year.
How a Car Depreciation Calculator Per Year Works
A yearly car depreciation calculator estimates how much your vehicle’s value decreases each year based on several factors.
Your calculator uses these inputs:
- Purchase Price
- Current Vehicle Age
- Vehicle Type
- Annual Mileage
- Years of Ownership
- Vehicle Condition
- Market Adjustment
Let’s break these down.
1. Purchase Price
This is your starting value.
If you enter $40,000, the calculator uses that as the base value and applies depreciation year by year.
Higher starting prices usually mean higher dollar losses, even if the percentage rate is the same.
2. Vehicle Type and Depreciation Rates
Different types of vehicles lose value at different speeds.
Here are the typical base depreciation rates used in the calculator:
| Vehicle Type | Base Depreciation Rate |
|---|---|
| Luxury | 25% per year |
| Truck/Pickup | 12% per year |
| SUV/Crossover | 15% per year |
| Sedan | 18% per year |
| Sports Car | 20% per year |
| Electric | 22% per year |
Luxury Vehicles
Luxury cars often depreciate quickly. They have high initial prices and expensive repair costs, which lowers resale demand.
Trucks and Pickups
Trucks usually hold value well. Strong demand and durability help reduce yearly depreciation.
Electric Vehicles
Electric vehicles can depreciate faster due to rapid technology changes and battery concerns.
3. First-Year Depreciation Is the Highest
Most vehicles lose the most value in year one.
The calculator increases depreciation in:
- Year 1 (up to 35%)
- Year 2 (higher than average)
- Then gradually lowers the rate after year 3
This reflects real-world patterns where a new car drops significantly once it becomes “used.”
Example:
- $35,000 new car
- May lose $7,000 to $10,000 in the first year alone
That is why many buyers prefer 1–2 year old vehicles.
4. Annual Mileage Impact
Mileage strongly affects car value.
Standard driving: 12,000 miles per year
If you drive more than 15,000 miles annually, depreciation increases.
The calculator adjusts value based on mileage factor:
- Higher mileage = higher yearly loss
- Lower mileage = slower depreciation
For example:
- 20,000 miles per year will reduce resale value significantly compared to 12,000 miles per year.
- Over 5 years, that difference can reach several thousand dollars.
5. Vehicle Condition Factor
Condition multiplies depreciation.
Options include:
- Excellent (1.0)
- Good (1.1)
- Fair (1.2)
- Poor (1.35)
A vehicle with accident history or mechanical problems loses value faster.
Example:
A $30,000 sedan in poor condition could lose thousands more over five years compared to the same car in excellent condition.
6. Market Adjustment
Car prices depend on supply and demand.
You can adjust for market conditions:
- +10% in a vehicle shortage
- -10% in a surplus market
For example, during supply chain shortages, used cars may hold value better.
What Results the Calculator Shows
After entering your data, the calculator provides:
1. Projected Future Value
Estimated resale value after selected years.
2. Total Depreciation
Total dollar amount lost.
3. Total Percentage Lost
Example: 52% over 5 years.
4. Average Annual Loss
Helps you understand yearly ownership cost.
5. Depreciation Per Mile
Useful for comparing vehicles.
6. Detailed Year-by-Year Table
Shows:
- Start value
- Annual depreciation
- Rate
- End value
- Cumulative loss
This helps you spot the “sweet spot” where depreciation slows down.
Example Calculation
Let’s say:
- Purchase price: $35,000
- Type: Sedan
- 12,000 miles per year
- 5 years ownership
- Excellent condition
Possible outcome:
- Year 1 value: ~$27,000
- Year 5 value: ~$16,000–$18,000
- Total loss: ~$17,000–$19,000
- Average annual depreciation: ~$3,500
This gives you a realistic expectation before buying.
Why a Yearly Depreciation Calculator Matters
Most buyers focus only on:
- Monthly payment
- Interest rate
- Insurance
But depreciation is often the largest cost.
Example:
- Fuel over 5 years: $8,000
- Insurance: $7,500
- Depreciation: $18,000
Ignoring depreciation can lead to expensive mistakes.
Best Strategies to Reduce Depreciation Loss
Here are simple ways to reduce yearly value loss:
1. Buy Slightly Used
Avoid the first-year depreciation hit.
2. Choose Low-Depreciation Types
Trucks and certain SUVs tend to hold value better.
3. Keep Mileage Reasonable
High mileage lowers resale price quickly.
4. Maintain the Vehicle
Full service history increases resale value.
5. Sell at the Right Time
Depreciation slows after 5–8 years for many vehicles.
When Should You Sell Your Car?
The calculator often shows:
- Sharp drop in years 1–3
- Slower depreciation after year 5
- Very slow loss after year 8–10
The ideal resale window is often between years 4–6.
At this point:
- You avoided steep early losses.
- The vehicle still holds solid market value.
