Annual percentage rate (APR)

Yearly interest rate charged on loans, including fees and other costs.

Definition

Annual percentage rate (APR) is the yearly interest rate charged on loans, including fees and other costs. Founders reach for it when a vague conversation needs a shared, specific meaning. Name it clearly, then let the next decision — a hire, a price, a test, or a pass — follow from that meaning.

In the room

How the word shows up in a real conversation.

Two cofounders disagree until they define Annual percentage rate (APR). Once they agree it means “Yearly interest rate charged on loans, including fees and other costs”, the argument becomes a decision.

Common mistake

Using Annual percentage rate (APR) as a label instead of a fact. If you cannot point to the evidence — a number, a customer, or a written assumption — you are using the word as jargon.
