Amortization

Amortization is allocating the cost of an intangible asset, or a loan principal, over time as a periodic charge. For amortization, the important details are the accounting period, source evidence, reviewer, materiality threshold, and control purpose that make the treatment auditable during close, reporting, and later review.

Also known as amortisation, intangible amortization

Why it matters

Understanding amortization matters because close, reconciliation, and audit work depend on consistent timing, source evidence, review thresholds, and ownership. A loose definition creates avoidable rework. When the term is tied to a source system, owner, and review cadence, it becomes easier to audit assumptions, catch changes early, and keep operators aligned.

In practice

  • Close example

    Teams use amortization during close, review, or audit support when a balance or transaction needs evidence. The controller should be able to trace the number to source records, timing, reviewer, and control threshold.

  • Review example

    Amortization should be reviewed whenever the source system, calculation logic, time period, or decision owner changes. That keeps the definition useful instead of letting it drift into a label.

In practice, teams should define amortization with a clear source, owner, time period, and decision before they use it in reporting, planning, or operating reviews.

When the term is tied to a source system, owner, and review cadence, it becomes easier to audit assumptions, catch changes early, and keep operators aligned.

A strong workflow for amortization separates the definition from the action: first agree what the term means, then decide how it is measured, when it changes, and who is accountable for the next step.

FAQ

What is amortization in accounting?

Amortization is allocating the cost of an intangible asset, or a loan principal, over time as a periodic charge. For amortization, the important details are the accounting period, source evidence, reviewer, materiality threshold, and control purpose that make the treatment auditable during close, reporting, and later review.

How is amortization different from depreciation?

The boundary for amortization differs from related terms by scope, source data, time period, and decision use. In this glossary, it covers allocating the cost of an intangible asset, or a loan principal, over time as a periodic charge, so teams should compare those boundaries before using it in reporting or planning.
