Opportunity Cost

02What People Think

If the receipt says one hundred dollars, that is what the purchase cost. Anything you did not buy belongs to a different conversation.

03What’s Underneath

A limited budget connects those conversations. Suppose the same hundred dollars could buy either a pair of shoes or the dinner you most wanted this month. Choosing the shoes gives up that dinner. The relevant alternative is the best available one you would actually have chosen, rather than a list of every imaginable use of the money.

Time makes the idea visible even when no cash changes hands. A free event can occupy the evening you would otherwise spend with a friend. The event may still be a wonderful choice. Opportunity cost describes the exchange involved; it does not supply a verdict that the cheapest, highest-paying, or most productive option must win.

The missing alternative rarely appears on a receipt. That makes the selected purchase easier to picture than what it displaced. A bargain can feel complete until someone remembers the other thing the same resources were meant to make possible.

04The Game

What was the strongest available alternative, and what happened to it when this choice became final? The revealing comparison is between two feasible uses of the same limited resources.
