Calculate annual depreciation, accumulated depreciation, and book value using straight-line depreciation.
Accumulated Depreciation Calculator
Free online accumulated depreciation calculator to estimate annual depreciation, total accumulated depreciation, and the remaining book value of an asset. This calculator is useful for business owners, accountants, finance teams, students, and anyone who needs a quick straight-line depreciation estimate. It helps you understand how much of an asset’s cost has already been expensed over time and how much value is still left on the books.
Accumulated depreciation is the total depreciation recorded on an asset from the date it is placed into service up to a selected point in time. Under the straight-line method, the same amount of depreciation is charged every year over the useful life of the asset. To use this method, you need the original asset cost, the salvage value, the useful life in years, and the number of years already used. Once those values are entered, the calculator shows the annual depreciation amount, the accumulated depreciation to date, and the remaining book value.
The formula of accumulated depreciation
Annual depreciation = (Asset cost – Salvage value) / Useful life
Accumulated depreciation = Annual depreciation x Elapsed years
Book value = Asset cost – Accumulated depreciation
Here asset cost means the original purchase price of the asset, salvage value means the expected value at the end of its useful life, useful life means the number of years the asset will be used for accounting purposes, and elapsed years means how many years of depreciation have already passed. In practice, accumulated depreciation should not exceed the total depreciable base, which is asset cost minus salvage value.
Solved Example
Example 1: Find the annual depreciation, accumulated depreciation, and book value if an asset costs $50,000, has a salvage value of $5,000, a useful life of 10 years, and has been used for 4 years.
Solve: Depreciable base = 50000 – 5000 = $45,000
Annual depreciation = 45000 / 10 = $4,500
Accumulated depreciation = 4500 x 4 = $18,000
Book value = 50000 – 18000 = $32,000
Example 2: Find the result if equipment costs $24,000, salvage value is $4,000, useful life is 5 years, and elapsed years are 3.
Solve: Depreciable base = 24000 – 4000 = $20,000
Annual depreciation = 20000 / 5 = $4,000
Accumulated depreciation = 4000 x 3 = $12,000
Book value = 24000 – 12000 = $12,000
Example 3: Find the result if a machine costs $80,000, salvage value is $8,000, useful life is 12 years, and elapsed years are 6.
Solve: Depreciable base = 80000 – 8000 = $72,000
Annual depreciation = 72000 / 12 = $6,000
Accumulated depreciation = 6000 x 6 = $36,000
Book value = 80000 – 36000 = $44,000

How to use this accumulated depreciation calculator
Enter the original asset cost in the proper input field. After that, enter the estimated salvage value, which is the amount you expect the asset to be worth at the end of its useful life. Next, enter the useful life in years and then the elapsed years for which you want to measure depreciation. Finally, click the calculate button. The calculator will show annual depreciation, total accumulated depreciation, and current book value in the result box.
This tool is helpful when preparing financial statements, reviewing asset schedules, checking depreciation for internal reporting, or studying basic accounting formulas. Because the calculator uses the straight-line method, the depreciation expense stays constant each year. That makes it easy to estimate how much value has been consumed and what balance remains. If the elapsed years approach the full useful life, accumulated depreciation will move closer to the total depreciable base.
When using the result, remember that accounting rules may differ by jurisdiction, company policy, and asset class. Some businesses use declining balance or units of production instead of straight-line depreciation. This page is designed for quick straight-line depreciation estimates, so it is best used for planning, education, and simple reporting checks. It gives you a fast way to understand asset cost allocation and how depreciation affects the carrying value of an asset over time.
