About Accumulated Depreciation
Accumulated depreciation is the total amount of depreciation expense that has been recorded against an asset since it was put into service. It’s a contra-asset account that reduces the original cost of the asset to arrive at its book value. Our depreciation calculator helps businesses and individuals accurately track this important financial metric.
Understanding accumulated depreciation is crucial for proper asset management, tax reporting, and financial statement preparation. Whether you’re using straight-line depreciation, declining balance, or other methods, our tool simplifies the calculation process.

Multiple Methods

Accumulated Depreciation Formula
The straight-line depreciation method uses this simple formula:
Annual Depreciation = (Asset Cost – Salvage Value) / Useful Life
Accumulated Depreciation = Annual Depreciation × Years Used
Book Value = Asset Cost – Accumulated Depreciation
Our calculator automates these calculations to provide instant, accurate results for your financial planning and reporting needs.
Example Depreciation Calculation
Let’s walk through a practical example to demonstrate how accumulated depreciation works:
Office Equipment Purchase
- Asset Cost: $15,000
- Salvage Value: $3,000
- Useful Life: 5 years
- Years Used: 3 years
1. Annual Depreciation = ($15,000 – $3,000) / 5 = $2,400 per year
2. Accumulated Depreciation = $2,400 × 3 = $7,200
3. Book Value = $15,000 – $7,200 = $7,800
After 3 years, the office equipment has $7,200 in accumulated depreciation and a remaining book value of $7,800.

Frequently Asked Questions
Depreciation expense is the amount recognized each accounting period, while accumulated depreciation is the cumulative total of all depreciation expenses recorded against an asset since its acquisition.
Method changes are generally allowed but may require justification and disclosure in financial statements. Consult an accountant for specific guidance.
Salvage value reduces the depreciable base (cost – salvage value). A higher salvage value results in lower annual depreciation expenses.
The asset’s book value equals its salvage value. No further depreciation is recorded unless the useful life or salvage value is reassessed.
Most businesses use either the half-year convention (6 months depreciation in first year) or prorate based on actual months in service.
