FormalTechnical

The value of the next best alternative that must be foregone when a choice is made.

Opportunity cost is not necessarily a monetary cost; it's about the value of what you give up. Every decision has an opportunity cost, even if it's just your time.

The story behind the word. This term is a compound of 'opportunity' (from Latin opportunitas, meaning 'fitness, advantage') and 'cost' (from Old French coste, related to Latin constare, 'to stand at a price'). It was coined by economists to highlight that every choice made comes with the 'cost' of the 'opportunity' to have pursued the next best alternative. It's a powerful reminder that resources are limited and choices have consequences.
