Linear Depreciation Calculator
When you buy assets—whether it’s a car, business equipment, or furniture—they lose value over time. This decline in value is called depreciation, and one of the simplest methods to calculate it is linear depreciation.
The Linear Depreciation Calculator is designed to help you quickly estimate how much an asset decreases in value each year. By entering just a few details, you’ll know the annual depreciation expense and the remaining value of the asset.
This tool is especially helpful for businesses, accountants, and individuals who need an easy and reliable way to plan for asset replacement or calculate expenses for tax and financial reporting.
What Is Linear Depreciation?
Linear depreciation, also called the straight-line depreciation method, spreads the cost of an asset evenly across its useful life.
For example, if you purchase a machine for $10,000 and expect it to last 10 years, the depreciation expense each year is: Depreciation Expense=Cost – Salvage ValueUseful Life\text{Depreciation Expense} = \frac{\text{Cost – Salvage Value}}{\text{Useful Life}}Depreciation Expense=Useful LifeCost – Salvage Value
So, if the machine has no salvage value: 10,000−010=1,000\frac{10,000 – 0}{10} = 1,0001010,000−0=1,000
That means the machine loses $1,000 in value every year.
How the Linear Depreciation Calculator Works
The calculator applies the straight-line formula automatically. You just provide:
- Initial Cost (Purchase Price) – How much you paid for the asset.
- Salvage Value – The estimated value at the end of its life (can be $0).
- Useful Life (Years) – The number of years the asset will be in use.
The result shows:
- Annual Depreciation Expense – How much value decreases each year.
- Accumulated Depreciation – Total depreciation at a given year.
- Book Value – The asset’s remaining value after depreciation.
Step-by-Step Instructions
Here’s how to use the Linear Depreciation Calculator:
- Enter Initial Cost
Input the purchase price of the asset (e.g., $10,000). - Enter Salvage Value
Enter the residual value you expect after its useful life (e.g., $1,000). - Enter Useful Life (Years)
Input the number of years the asset will be in service. - Click “Calculate”
The tool will instantly give you the annual depreciation and the value breakdown. - Optional Tools
- Use Reset to clear fields.
- Use Copy to save results.
Practical Example
Imagine you bought a laptop for $2,000, and you expect it to last 5 years with no salvage value. 2,000−05=400\frac{2,000 – 0}{5} = 40052,000−0=400
The laptop depreciates $400 per year. After 3 years, its book value will be: 2,000−(400×3)=8002,000 – (400 \times 3) = 8002,000−(400×3)=800
This shows your laptop is worth $800 after 3 years.
