What does amortization mean?
Amortization refers to the process of gradually reducing a financial obligation or asset value through systematic, periodic payments or accounting charges. In lending, it describes how a loan — most commonly a mortgage — is repaid in fixed installments, with each payment divided between interest and principal so that the balance steadily declines to zero by the end of the term. In accounting, amortization is the parallel practice of expensing the cost of intangible assets such as patents, copyrights, or goodwill over their expected useful lives, much as depreciation does for physical assets. The word derives from Latin roots connected to mortality, evoking the idea of 'killing off' a debt bit by bit. Amortization is essential to personal finance, corporate accounting, and investment analysis, appearing everywhere from mortgage statements to audited financial reports, and understanding it helps borrowers grasp how much of each payment truly builds equity.
nounThe gradual reduction of a debt or the book value of an intangible asset through regular, scheduled payments or charges over a fixed period.
- The systematic repayment of a loan through regular payments of principal and interest over time.
- The accounting practice of spreading the cost of an intangible asset over its useful life.
"The company's amortization schedule showed how each monthly payment reduced both interest and principal on the loan."
"Her mortgage amortization schedule revealed that early payments went mostly toward interest rather than principal."
"The firm recorded annual amortization of its patent, spreading the acquisition cost across fifteen years."
Rarely used; amortization usually appears as an uncountable mass noun referring to the process or concept. A plural form may appear when discussing multiple distinct amortization schedules or entries.
"The audit reviewed several amortizations recorded across different subsidiaries."
The word 'amortization' literally means 'killing' — it comes from Latin roots meaning death, because each payment gradually 'kills off' your debt until it's dead.

Etymology of amortization
Amortization entered English from French in the late medieval and early modern period, ultimately deriving from the Latin root 'mors' (death) via words meaning mortal or subject to death. The underlying sense was that a debt would be 'killed off' — extinguished gradually through payments — hence the connection to terms like 'mortgage,' which shares the same Latin ancestry. The financial meaning of systematically extinguishing a debt became established in English commercial usage, and the accounting sense of writing down intangible asset values developed later as modern corporate accounting matured.
