An Accumulated Depreciation Calculator helps businesses and accountants quickly determine the total depreciation of an asset over time. By entering factors like asset cost, useful life, and depreciation method, you can accurately track value reduction.

What Is Accumulated Depreciation?
Accumulated depreciation is the total depreciation expense recorded against a fixed asset from acquisition up to a specific date. It is a contra-asset account on the balance sheet, carrying a credit balance and subtracted from gross asset cost to reveal the asset’s net book value.
Each period a company records depreciation, that amount is simultaneously added to this account. Over the asset’s useful life, accumulated depreciation grows until it equals the depreciable cost (original cost minus salvage value), at which point the asset is fully depreciated.
Understanding accumulated depreciation is essential for:
- Accurately reporting asset values on financial statements
- Tax planning and deduction optimization
- Making informed asset replacement decisions
- Calculating return on assets and other financial ratios
- Compliance with GAAP and IFRS accounting standards
Accumulated Depreciation = Σ (Annual Depreciation Expenses recorded to date)
Depreciation Methods Comparison Explained
1. Straight-Line Depreciation (SL)
The most widely used method, it spreads the depreciable cost evenly across all years of useful life, resulting in an identical expense each period.
Accumulated Depreciation (Year n) = Annual Depreciation × n
2. Declining Balance (DB) / Double Declining Balance (DDB)
An accelerated method applying a fixed rate to the remaining book value each year. Depreciation is highest in early years and tapers over time. The DDB variant uses twice the straight-line rate.
Annual Depreciationn = Book Valuestart of year × Rate
Accumulated Depreciation (Year n) = Cost − Book Valueend of year n
3. Sum-of-Years-Digits (SYD)
Another accelerated method. A decreasing fraction is applied to depreciable cost each year, the numerator decreases by one annually; the denominator is the sum of all year-digits.
Annual Depreciation (Year k) = (Remaining life at start of year ÷ SYD) × Depreciable Cost
Accumulated Depreciation (Year n) = Σ Annual Depreciation from Year 1 to Year n

Accumulated Depreciation Examples
Example 1 – Manufacturing Equipment (Straight-Line)
A factory purchases machinery for $80,000 with a salvage value of $8,000 and useful life of 8 years. Annual depreciation = ($80,000 − $8,000) ÷ 8 = $9,000/year. After 5 years, accumulated depreciation = $9,000 × 5 = $45,000; book value = $80,000 − $45,000 = $35,000.
Example 2 – Company Vehicle (Double Declining Balance)
A delivery van costs $40,000 with a $4,000 salvage value and 5-year life. DDB rate = (2 ÷ 5) × 100% = 40%. Year 1 depreciation = $40,000 × 40% = $16,000. Year 2 = $24,000 × 40% = $9,600. Accumulated after Year 2 = $25,600.
Example 3 – Office Furniture (Sum-of-Years Digits)
Office furniture costs $12,000 with a $2,000 salvage value and 5-year life. SYD = 5+4+3+2+1 = 15. Year 1 = (5/15) × $10,000 = $3,333. Year 2 = (4/15) × $10,000 = $2,667. Accumulated after Year 2 = $6,000.
