Principles of Macroeconomics / Unit 1   MAC 0020 short lesson, about 20 seconds

Sunk Costs

Captions available

The idea

A sunk cost is money or effort already spent that cannot be recovered, so it should not affect a current decision.

In practice

Walking out of a bad film does not waste the ticket; it is spent either way.

Where people slip

Opportunity cost looks forward at what a choice gives up; sunk cost looks back at what is already gone.
