What is revenue?

Is there a way the business figures how much they made?
user
Yes, a business can use the revenue formula: Revenues = Gross Profit + Total Costs.  This formula assumes that all of the costs are fixed, which is sometimes true.
assistant
So all businesses basically work the same?
user
To an extent, yes.  A retail business sells things, for example, which is the same as a drug company, which sells prescription drugs, which is the same as an information technology company, which sells online services.  But a business may have different products, services, costs, and revenue goals.
