Amortize

Amortization

1. A tax deduction for the gradual consumption of the value of an asset, especially an intangible asset. For example, if a company spends $1 million on a patent that expires in 10 years, it amortizes the expense by deducting $100,000 from its taxable income over the course of 10 years. It is often used interchangeably with depreciation, which technically refers to the same thing for tangible assets.

2. The act of repaying a loan in regular payments over a given period of time.

amortize

To write off gradually and systematically a given amount of money within a specific number of time periods. For example, an accountant amortizes the cost of a long-term asset by deducting a portion of that cost against income in each period. Likewise, an investor will usually amortize the premium each year on a bond purchased at a price above its principal.
