The best way to explain cost per wear is with the story of the boxy, heavy duty cotton t-shirt.
Imagine you received an oversized, cheaply printed and boxy fitting t-shirt at your work’s annual barbeque. Wearing this shirt is like wearing a thin blanket that goes to your knees, and has a head hole the size of a basketball.
You might wear this shirt for the day, maybe use it for some lawn care, but after about 10 or so washes the logo is faded and the fabric is even more stretched out than before, so you throw it away.
Now, let’s assume that shirt cost your company $13 and you wore it 12 times. That would mean its cost per wear would be $1.08. Now imagine that same barbeque, but instead you receive a nice tri-blend shirt.
You like the way it fits, and like the people you work for, so you decide to wear it a lot. It slowly became your new favorite shirt. You laugh in it, you cry in it and share many good memories with this shirt.
After wearing it 90 times, the logo has begun to fade, and the fabric is worn. You decide it is time to retire your favorite shirt, and after a few tears, it ends up being thrown away.
The initial cost for that shirt was $25 and it was worn 90 times, so the cost per wear was about 27 cents, much lower than the boxy t-shirt, but it had far more utility than just the initial cost divided by the times it was worn.
