Gross operating surplus

Gross operating surplus is the money left after a business has paid for all of the things it needs to run, like the cost of the supplies, equipment, and labor it uses to make its products. It is like the money a business makes when it subtracts what it spent to make its products from what it earned selling them. That money is the gross operating surplus, and it is the money a business can use to do things like pay its bills and save for the future.
