Definition
Operating income is the profit generated from core business operations before interest and taxes. 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 Operating income. Once they agree it means “Profit generated from core business operations before interest and taxes”, the argument becomes a decision.
Common mistake
Using Operating income 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.
