Opportunity Cost
What is the best alternative you give up? Start there, then choose the calculation or comparison that fits your decision.
Opportunity cost connects a choice to the next-best alternative that is actually available. That sounds simple until the options involve different units, limited time or benefits that cannot be reduced to money. This collection separates the basic concept from the calculations and comparisons that often get mixed together. You can enter through the definition, a complete decision example, or a particular source of confusion.
Read the concept article first if you need to identify the alternative. Choose the calculation guide to work through a specific choice; use the formula article when units or a production graph are the main question. The comparison articles distinguish opportunity cost from money already spent and from the broader idea of a trade-off. Increasing opportunity cost addresses a further question: how the sacrifice can change as production shifts. Pick the route that resolves your question rather than combining unlike quantities into a single number.

Before you read
Should I read the formula or the calculation guide first?
Use the calculation guide for a complete choice between alternatives. Use the formula article when you need to understand the units or a graph-based calculation. They address related but different tasks.
Is every trade-off an opportunity cost calculation?
A trade-off describes a sacrifice between competing aims. An opportunity cost comparison focuses on the best alternative forgone. The dedicated comparison article explains why keeping that distinction can make a decision clearer.
What if the alternatives cannot all be measured in money?
State the nonfinancial benefits and constraints separately rather than inventing precise values. The calculation guide includes choices involving time and other benefits, where a single monetary total may not settle the decision.
