Opportunity cost

Opportunity cost: The real cost of a choice is the best thing you did not do with the same time or money.

Free — no account needed to read

The real cost of a choice is the best thing you did not do with the same time or money.

Try it now

Take something you are about to commit to. Write what else you would do with those exact hours and that exact money.

What to do with the answer

Compare against that alternative, not against doing nothing. "Is it good?" is the wrong question.

Where it misleads

Applied to every small decision it is paralysing. Save it for commitments large enough to matter.

The module it belongs to

  • Decision Thinking — Make better decisions under uncertainty

Previous: Second-order thinking

Next: Reversible and irreversible
