Cost Per Use Calculator
Price tells you what leaves your account today. Cost per use tells you what the thing is worth having. A $400 coat worn twice a week for five years costs less per wearing than an $80 one replaced every winter.
Be honest — this is where the maths usually turns.

How this calculator works
Total uses = uses per year × years kept. Net cost = price − resale value, floored at zero. Cost per use divides one by the other; cost per year divides the net cost by the years.
Purchase price only — maintenance, consumables, insurance, and storage are excluded. Nothing is discounted for the time value of money, which is immaterial at these amounts and horizons.

Frequently asked questions
How is cost per use calculated?
Subtract anything you will recover by reselling, then divide by the total number of uses — uses per year multiplied by the years you keep it. A $400 coat worn 60 times a year for five years and resold for $50 works out to about $1.17 per wearing.
Does this justify buying expensive things?
Only when the expensive version genuinely lasts or gets used more. The maths cuts both ways: it is just as good at exposing the premium item worn twice, and the equipment bought for a hobby abandoned in March. The honest input is uses per year, not price.
What about maintenance and running costs?
Not included — this covers purchase price against uses. For things that cost money to run (a car, a printer, a boat), add the annual running cost to the price before entering it, or the comparison flatters the expensive option.
Should I use this for subscriptions?
Yes, and it is unusually revealing there. Enter the annual price, the number of times you actually used it, and one year: a $180 streaming service watched eight times costs $22.50 an evening, which is a different decision from '$15 a month'.
