Useful life

The expected period of time during which a depreciating asset will be productive.

Useful Life

The amount of time, as determined by the IRS, that an asset is expected to be used. The useful life is important in determining taxes assessed on the depreciated value of the asset each year. Theoretically, an asset's useful life is equal to its absolute physical life, but, because the useful life is an estimation, this is not always the case.
