Legal Definition
Depreciation is the accounting concept used to allocate the cost of a tangible asset over its useful life, reflecting the systematic expense of an asset's value over time. In legal contexts, it dictates how the capitalized cost of an asset (like machinery or real estate) is spread across fiscal periods for tax purposes.
Plain-English Translation
Imagine you bought a big machine for your business. Depreciation is like figuring out that machine costs money over many years, so the business doesn't just see the whole cost in one year; instead, it spreads the cost of the machine over time, which helps the business plan its taxes.
