Calculate how much your 2018 vehicle will depreciate over time using this free online calculator. Depreciation estimates help you understand the value of your car, truck, or SUV as it ages.
How to Use This Calculator
Using the 2018 auto depreciation calculator is simple:
- Enter your vehicle's original purchase price
- Select the expected annual depreciation rate (typically 15-25%)
- Choose how many years you want to track depreciation
- Click "Calculate" to see your results
The calculator will show you the depreciated value of your vehicle each year, along with a chart showing the depreciation trend over time.
Depreciation Formula
The calculator uses the straight-line depreciation method to estimate your vehicle's value over time. The formula for calculating depreciated value is:
Depreciated Value = Original Price × (1 - (Depreciation Rate × Years))
Where:
- Original Price - The purchase price of your vehicle
- Depreciation Rate - The annual rate at which your vehicle loses value (expressed as a decimal)
- Years - The number of years you want to track depreciation
For example, if you buy a $30,000 vehicle with a 20% annual depreciation rate, after 3 years its value would be:
$30,000 × (1 - (0.20 × 3)) = $30,000 × 0.40 = $12,000
Worked Examples
Example 1: Moderate Depreciation
Let's calculate the depreciation of a $25,000 car with a 15% annual depreciation rate over 5 years.
| Year | Depreciated Value |
|---|---|
| 1 | $21,250 |
| 2 | $18,750 |
| 3 | $16,500 |
| 4 | $14,475 |
| 5 | $12,700 |
Example 2: Faster Depreciation
Now let's look at a $40,000 truck with a 25% annual depreciation rate over 4 years.
| Year | Depreciated Value |
|---|---|
| 1 | $30,000 |
| 2 | $22,500 |
| 3 | $16,875 |
| 4 | $12,656 |
