How does the straight-line method affect the depreciation rate?

The straight-line method of depreciation results in a consistent and equal annual expense throughout the useful life of an asset. This is achieved by calculating the total depreciable amount (the asset's cost minus its salvage value) and then dividing this figure by the number of years the asset is expected to be in use. As a result, the same dollar amount of depreciation is recorded each year, meaning that the rate remains constant.

This consistency is particularly useful for budgeting and financial reporting, as it simplifies the accounting process and allows for straightforward forecasting. It contrasts with other methods, such as declining balance or units of production, where the depreciation expense can fluctuate based on specific parameters or usage rates.
