Opportunity Cost
What is Opportunity Cost?
The next best alternative forgone when a choice is made. Because resources are scarce, choosing one option always means giving up others; the opportunity cost is the value of the single best option that was rejected, not the money spent and not the sum of every rejected option.
This definition is part of the Understanding Business Activity chapter in Cambridge O Level Business Studies.
Opportunity Cost in context
Business activity is the combining of scarce resources — land, labour, capital and enterprise — to produce goods or services that satisfy human needs and wants. Because resources are scarce and wants are not, every choice carries an opportunity cost: the next best alternative forgone. Cambridge O Level Business Studies (7115) Chapter 1 covers why business activity exists, how a business is classified by economic sector and by ownership sector, how size and growth are measured, the forms of business organisation from sole trader to public corporation and what each means for ownership, control, finance and risk, and the objectives that businesses set and that their stakeholders judge them by.
Common mistakes with Opportunity Cost
- “Opportunity cost is the money you spend.” Correct Opportunity cost is the next best alternative forgone — the single best option you gave up, not the price paid and not the full list of rejected options.
- “Public-sector organisations do not have to worry about cost.” Correct Public money is scarce too, so every public-sector decision has an opportunity cost. Efficiency matters in both sectors; what differs is the objective the efficiency serves.
Examiner tips on Opportunity Cost
- Applying it in a case. Opportunity cost is not only about money. A sole trader who works Saturdays gives up leisure; a factory that switches a production line to product X gives up the output of product Y. Name the specific alternative from the case, not “something else”.
Questions students ask about Opportunity Cost
What is opportunity cost?
Opportunity cost is the next best alternative forgone when a choice is made. Because resources are scarce, choosing one option always means giving up others, and the opportunity cost is the value of the single best option that was rejected — not the money spent, and not the sum of every rejected option. If a business spends its capital on a new machine, the opportunity cost is the best use it gave up, such as the marketing campaign it could have funded instead.
