Cost per use (Kosten pro Nutzung)
Cost per use divides an item's total cost by the number of times you actually use it, turning a one-time price into a recurring rate. A €120 pair of boots worn 300 times costs €0.40 per wear; a €40 pair worn 10 times before falling apart costs €4 per wear. The cheaper sticker price is not always the cheaper choice.
Why it matters
For someone rebuilding a household budget after a move, cost per use reframes "expensive" versus "cheap" from sticker price to value actually delivered. It counters both impulse buying toward the lowest upfront number and reflexive frugality that skips durable goods entirely. The concept applies across clothing, tools, kitchen equipment, and subscriptions — anywhere a purchase gets used more than once. It does not override cash-flow reality: a lower cost-per-use item can still be the wrong choice this month if the upfront price exceeds what is available to spend right now.
Worked examples
1. Two winter coats. Coat A costs €40 and lasts roughly 8 wears before the seams give out. Coat B costs €150 and lasts roughly 300 wears. The lower price tag does not mean the lower cost per wear.
| Item | Price | Expected uses | Cost per use |
|---|---|---|---|
| Coat A | €40 | 8 wears | €5.00 |
| Coat B | €150 | 300 wears | €0.50 |
Coat B costs almost four times as much upfront but ten times less per wear — as long as 300 wears actually happen, which depends on climate, wardrobe rotation, and how long the coat survives.
2. A gym membership used unevenly. A membership costs €40 per month, or €480 per year. Visiting twice a week — about 100 visits a year — puts cost per use at €480 / 100 = €4.80. Visiting twice a month — 24 visits a year — puts it at €480 / 24 = €20.00 per visit. The subscription price never changes; the cost per use does, entirely as a function of how often it gets used.
Cost per use also flags the point where paying per session (a drop-in class, a day pass) beats a subscription: if a drop-in costs €8 and expected use is under 5 sessions a month, the drop-in path has a lower cost per use than the €40 membership, even though the membership looks like the "better deal" per unit of access.
