What Is Useful Life?
The useful life of an asset is an accounting estimate of the duration it is expected to remain functional and generate revenue. This estimate is crucial for determining how long an asset can be depreciated. Multiple factors impact useful life estimates, such as usage patterns, the asset’s age at purchase, and technological advances.
Gaining a Clear View of Useful Life
Useful life pertains to the estimated duration, usually in years, for which various business assets remain valuable. This includes buildings, machinery, equipment, vehicles, electronics, and furniture. The useful life ends when assets become obsolete, require substantial repairs, or stop providing economic benefits. Correctly estimating useful life aids in creating accurate depreciation schedules, which are pivotal for financial planning and accounting.
Useful Life and Straight-Line Depreciation
In the straight-line depreciation model, the cost of an asset is divided by its estimated useful life to determine the annual depreciation amount. This value is then equally depreciated over the years. For example, if an asset costs $1 million and has an estimated useful life of 10 years, its annual depreciation would be $100,000.
Useful Life and Accelerated Depreciation
Alternatively, businesses might prefer higher depreciation at the start of the useful life period with the decreasing amount over time, employing the accelerated depreciation model. In this approach, depreciation write-offs reduce yearly at a fixed percentage until reaching zero. The sum-of-the-years-digits method further allows decreasing depreciation by a certain dollar amount annually throughout the useful life until full depreciation is achieved.
Making Adjustments to Useful Life
Useful life estimates can be modified under different conditions, such as early asset obsolescence due to new technologies. When making such adjustments, businesses must provide the IRS with detailed documentation and justification. For instance, if original estimates predicted a 10-year useful life for an asset, but technological advancements reduce this to 8 years, companies can modify their depreciation schedules accordingly. This results in higher yearly depreciation based on the new, shorter useful life estimate.
