A related idea is depreciation. You haven't lost $700 by buying a pair of skis. You have exchanged $700 in cash for at least $500 in a pair of skis that is now previously owned. So you might lose, say, $200 immediately for the privilege of buying something brand new. And then another $100 if we include up-front the effort to sell them to someone else. But the rest of the money is still there, in the shape of skis. As you use the skis they will depreciate in their second hand value -- this is when the money is actually lost, bit by bit. You can estimate how much the second-hand value of the skis are with 10 uses, 100 uses, 1000 uses, and so on. This is the real cost per use. |
