What this metric means

Accumulated depreciation is the total depreciation expense recognised on an asset to date. It reduces the asset’s book value and reflects how much of its useful life has been consumed.

How to calculate it

Straight-line: annual depreciation = (Cost − Salvage) ÷ Useful life. Accumulated = annual × years in service. Book value = Cost − Accumulated. Double-declining balance applies a rate of 2 ÷ useful life to the remaining book value each year, never below salvage.

How to interpret your result

Use the schedule to see how depreciation and book value change each year. Current book value is what you’d show on the balance sheet. Compare with disposal value if you’re planning to sell or replace the asset.

FAQs

What is accumulated depreciation?▾
Accumulated depreciation is the total amount of depreciation expense recorded on an asset since it was put in service. It reduces the asset’s carrying (book) value on the balance sheet.
What’s the difference between straight-line and double-declining balance?▾
Straight-line spreads the depreciable amount evenly over useful life. Double-declining balance front-loads depreciation: each year you apply a fixed rate to the remaining book value, so early years have higher expense. DDB never goes below salvage value.
How do I interpret book value?▾
Book value = cost minus accumulated depreciation. It’s the amount still carried on the books, not necessarily what you could sell the asset for. Use it for balance sheet reporting and to see how much of the asset is “used up.”
Can I use fractional years in service?▾
Yes. Enter years in service as a decimal (e.g. 2.5). For straight-line, accumulated depreciation is annual depreciation × years in service. For DDB, the calculator applies the method year by year up to that point.
When should I use DDB?▾
DDB is common for assets that lose more value early (e.g. vehicles, tech). It matches higher expense to higher use. Many firms use straight-line for simplicity and consistency; check your accounting policy.
