Frequently Asked Questions
What is straight-line depreciation?
Straight-line depreciation spreads the cost of an asset evenly across its useful life. Annual Depreciation = (Cost − Salvage Value) ÷ Useful Life in Years.
What is book value of an asset?
Book value is the original cost of an asset minus accumulated depreciation. It represents the asset's net value on the balance sheet at a given point in time.
When should I use declining balance instead of straight-line?
Declining balance is better when an asset loses value more quickly early in its life (e.g., vehicles, technology). Straight-line suits assets that provide consistent value over time.
