Accumulated Depreciation

Definition

Accumulated Depreciation refers to the total decrease in value that an asset has undergone since it was acquired. It is the aggregate of periodic depreciation expenses recorded on the asset since its purchase and represents the estimated usage or wear and tear on an asset.

Depreciation is typically calculated on a straight-line basis, where the same amount is deducted every year. This accumulated amount helps companies understand how much of the asset’s cost has been written off.

Examples

Example 1: Straight-Line Depreciation
- Asset Purchase: A building is purchased for $1,000,000.
- Depreciation Method: Straight-Line Depreciation
- Annual Depreciation Expense: $25,000
- Accumulated Depreciation after 3 years: $25,000 per year * 3 years = $75,000
Example 2: Double-Declining Balance Method
- Asset Purchase: Machinery is purchased for $200,000.
- Depreciation Method: Double-Declining Balance
- Annual Depreciation Expense (Year 1): $40,000 (20% of $200,000)
- Annual Depreciation Expense (Year 2): $32,000 (20% of $160,000)
- Accumulated Depreciation after 2 years: $40,000 (Year 1) + $32,000 (Year 2) = $72,000

Frequently Asked Questions

Q1: How is accumulated depreciation calculated?

Accumulated depreciation is calculated by summing all the periodic depreciation expenses recorded for an asset from the time it was acquired until the current period.

Q2: Does accumulated depreciation affect an asset’s book value?

Yes, accumulated depreciation reduces an asset’s book value on the balance sheet. The book value is calculated as the original cost of the asset minus the accumulated depreciation.

Q3: Can accumulated depreciation be reversed?

Accumulated depreciation itself generally isn’t reversed. However, early retirement, sales, improvements to the asset, or a change in depreciation method may require adjustments.

Q4: What’s the difference between depreciation expense and accumulated depreciation?

Depreciation expense refers to the amount of depreciation allocated for a specific period, typically annually. Accumulated depreciation is the total amount of depreciation that has been recorded against the asset up to a certain date.

Depreciation Expense: The amount of depreciation allocated for an asset for a specific period.
Straight-Line Depreciation: A depreciation method where an equal amount of depreciation is expensed each year over the asset’s useful life.
Adjusted Tax Basis: The asset’s original cost basis minus accumulated depreciation, adjusted for any improvements or changes in value.
Useful Life: The estimated time period an asset is expected to be useful for the purpose for which it was acquired.
Book Value: The net value of an asset in the accounting records, calculated as cost minus accumulated depreciation.
