Frequently Asked Questions
Common questions regarding asset depreciation accounting.
Q.What is the difference between Straight-Line and Declining Balance depreciation?
Straight-Line depreciation distributes the asset's depreciable cost evenly over its useful life, resulting in a constant annual expense. Declining Balance is an accelerated method that applies a constant percentage to the remaining book value, resulting in higher depreciation expenses in the early years of the asset's life.
Q.How does a partial first year affect depreciation?
If an asset is purchased mid-year, it cannot be depreciated for a full 12 months in the first year. The calculator applies a pro-rata monthly factor (e.g., 6/12 if purchased in July) to the annual rate, and pushes the remaining fraction to a new final year (Year L+1) so the asset is fully written down to its salvage value.
Q.Can an asset be depreciated below its salvage value?
No. Under both GAAP and IFRS rules, an asset's book value cannot fall below its estimated salvage value. The calculator automatically caps the final depreciation expense to prevent the book value from dropping below this threshold.
Q.Is my financial data safe from remote servers?
Yes. The depreciation schedule generator runs entirely in your local browser tab. No financial data is sent across the internet.
