Opportunity Cost: Why You Can Never Have Both

Every “yes” is secretly a “no” to something else.

The big idea

The real cost of anything is the next best thing you gave up to get it.

Taylor Swift can play one stadium show tonight, or she can spend the night writing new songs. If the concert earns $5 million but a new hit could earn $10 million, the cost of performing isn’t zero. It’s the $10 million she gave up. Economists call that the opportunity cost.

Opportunity cost exists because of scarcity. Time, money, workers and land are all limited, so every choice uses up something that could have gone somewhere else. If resources were unlimited, you’d never have to choose and economics wouldn’t exist.

The trick is to always ask: “compared to what?” An hour of overtime costs you an hour with your kids. A company that builds one more SUV can’t use that steel, those workers and that factory time to build something else. The price tag is only part of the cost.

Spot it in the wild

BusinessesCompanies sometimes kill products people still buy, because the factory time is worth more making something else.
GovernmentsMoney spent on defense is money not spent on schools or hospitals. Every budget is a list of trade-offs.
