About the Cost Per Use Calculator

Frequently asked questions
+What cost per use is good?
Under $1/use is excellent. $1–$5 is good. Over $20 suggests renting or borrowing may be smarter.
+Does this apply to clothes?
Yes — the cost-per-wear framework is popular in fashion. A $300 blazer worn 150 times = $2/wear. A $30 shirt worn once = $30/wear.
