How to Use the Depreciation Calculator
Enter your asset details, choose a depreciation method, and get a depreciation schedule based on your numbers.
1
Enter Your Asset Cost
Add the original cost of the asset you want to depreciate. This is the starting value used in the depreciation calculation.
2
Add the Salvage Value
Enter the expected salvage value of the asset at the end of its useful life. This field is optional.
3
Enter the Useful Life
Add how many years you expect the asset to be in use. The calculator uses this to determine the depreciation period.
4
Choose a Depreciation Method
Select the method you want to use, such as straight line depreciation or the diminishing balance method.
5
Select the In-Service Starting Month
Choose the month the asset was placed into service. This helps determine when depreciation begins.

Understanding Depreciation Calculations
Depreciation spreads the cost of an asset over its useful life. The method you choose determines how much depreciation is recorded each year and how quickly the asset’s book value decreases.
Straight Line Depreciation Formula
The straight line depreciation method spreads the depreciable cost evenly across the asset’s useful life.
Depreciation per Year = (Asset Cost − Salvage Value) ÷ Useful Life
Depreciation Calculation Example
For a $10,000 asset with a $1,000 salvage value and a 5-year useful life, the annual depreciation is $1,800. The same amount is recorded each year using the straight line method.
Diminishing Balance Method
The diminishing balance method applies depreciation to the asset’s remaining book value, so the depreciation expense is higher in earlier years and decreases over time.
Avoid Common Depreciation Errors
Use the correct asset cost, salvage value, useful life, and in-service date. Choosing the wrong depreciation method or entering incorrect figures can affect your depreciation schedule and accounting records.

Depreciation Calculator FAQs
The calculation depends on the method you use. With straight line depreciation, subtract the salvage value from the asset cost and divide the result by its useful life.
The depreciation formula depends on the method. For the straight line method, the formula is: (Asset Cost − Salvage Value) ÷ Useful Life.
A 20% depreciation rate means an asset depreciates by 20% of its applicable value during the period. The actual amount depends on the depreciation method and the asset’s current book value.
A 40% depreciation rate means 40% of the applicable asset value is recorded as depreciation for the period. With an accelerated method such as double declining balance, the depreciation amount can be higher in the earlier years.
Straight line depreciation spreads an asset’s depreciable cost evenly across its useful life. It is one of the simplest methods used for accounting and fixed asset records.
The diminishing balance method calculates depreciation based on the asset’s remaining book value. This results in higher depreciation earlier in the asset’s life and lower depreciation as the asset becomes older.
Double declining balance is an accelerated depreciation method that records more depreciation in the earlier years of an asset’s useful life. It uses twice the straight line depreciation rate.
Salvage value is the estimated value of an asset at the end of its useful life. For straight line depreciation, it is subtracted from the asset cost before calculating the annual depreciation expense.
Yes. You can use an Excel formula to calculate depreciation, with the formula depending on the method you choose. A depreciation calculator is a quicker way to calculate the amount and generate a depreciation schedule.
The straight line method records the same depreciation amount each year. Accelerated depreciation methods, such as diminishing balance and double declining balance, record more depreciation in the earlier years and less later.
