The cost-per-use habit

A $200 jacket sounds expensive. But if you wear it 200 times, it costs a dollar a wear. A $30 gadget sounds cheap — until you use it twice and it lives in a drawer forever, at $15 a use. Sticker price lies. Cost per use tells the truth.

The cost-per-use habit is a tiny question you ask before any buy: how much will this cost me each time I actually use it?

The math is grade-school easy

Price divided by the number of times you'll really use it. $120 boots worn 100 times? About a dollar a wear. A $90 gadget used five times? $18 a use. Same dollars out the door, wildly different value.

Why it beats “is it cheap?”

Cheap things you never use are the most expensive things you own, per use. Expensive things you use daily can be a bargain. The habit stops you from chasing low prices and starts you chasing real value.

Be honest about “uses”

The trap is lying to yourself: “I'll totally use this every day.” Look at your real history, not your hopes. If the last three hobby gadgets died in a drawer, count this one the same way.

The bigger cost behind the buy

Cost per use compares the thing to itself. Opportunity cost compares it to your future. A $90 gadget isn't just $18 a use — it's also the growth that $90 won't earn. (See: what is opportunity cost.)

Where it shines

Use it hardest on gear, gadgets, and clothes — the stuff we overbuy on a fantasy of how often we'll use it. (See: needs vs wants, the honest line.)

The takeaway

Stop asking “is this cheap?” Start asking “what does this cost me each time I use it?” The answer kills a lot of cheap clutter and quietly approves the things worth keeping.
