Enter what a garment costs, how many times you realistically expect to wear it, and anything it will cost to maintain. The calculator returns the cost per wear, and the wear counts at which it crosses common value thresholds.
Use an honest wear count
The arithmetic is trivial. The estimate is not, and it is the only input that matters.
Almost everyone overestimates. The fix is to stop imagining and start anchoring: find the piece in your wardrobe this would replace, and work out how often you actually wore that one over the last twelve months. If you cannot say, that is worth knowing — it usually means the honest number is lower than the one you were about to type.
What counts as upkeep
Anything you will spend to keep the garment wearable across its life: dry cleaning, resoling, alterations, replacement buttons. For most everyday clothes this is zero. For tailoring, outerwear and good shoes it is often substantial enough to change the answer.
Reading the result
The headline number is only meaningful next to an alternative. Cost per wear works as a comparison between two specific options you are actually choosing between, not as a pass/fail test on a single purchase. Run it twice — once for each option — and compare.
The threshold rows underneath answer the more useful question: how many times would you have to wear this before it became good value? If that number is higher than the realistic wear count for its category, the piece has answered you.
