The “expensive” boots
$220 · 312 wears over six winters
per wear$0.71
A four-figure closet staple that costs less than a bus ride each time you pull it on.
The math of wearing
Cost per wear, calculated.
Cost per wear (CPW) divides what you paid for an item by how many times you actually wear it. One small number turns a closet full of receipts into a wardrobe that has to earn its keep. Here is the formula, the math on real-world examples, and how Armoiria runs it for every item you own — automatically.

The formula
cost per wear price ÷ times worn
That's the whole calculator. The hard part was never the division — it's knowing the “times worn” for 200 items. Pen-and-paper CPW dies at item three; the number is only honest if the wears are counted for you.
Two more modes for the pieces the basic formula treats unfairly: resale-adjusted cost per wear and cost per season. Bloggers: the calculator is also embeddable on your own site.
Frequently asked questions
What is cost per wear?
The price of an item divided by the number of times you actually wear it. It reframes every purchase around service rendered instead of sticker price: a $220 coat worn 312 times cost $0.71 per wear; an $18 top worn twice cost $9.
How do I calculate cost per wear?
Divide price by times worn. The hard part is the denominator — counting wears across a whole closet by hand dies at item three, which is why Armoiria counts them for you from your outfit logs.
What is a good cost per wear?
There is no universal target, but as a rule of thumb items under $1–2 per wear behave like wardrobe staples, and anything above $5 per wear is usually a purchase to learn from. Compare items against your own closet average, not a magazine list.
Does cost per wear work for seasonal items or resale?
Those have their own modes: cost per season divides the price by seasons of use for winter coats and other part-year gear, and resale-adjusted cost per wear subtracts expected resale value before dividing. Both calculators are linked from this page.
Run the math
Three illustrative items, same question: what did it really cost to wear this?
The “cheap” top
$18 · 2 wears before the seam went
per wear$9.00
The bargain that wasn’t. Nearly thirteen times more expensive per wear than the boots.
The workhorse coat
$260 · 140 wears and counting
per wear$1.86
Falling with every wear — the graph goes down while the compliments go up.
The cheapest clothes you own are the ones you never wear. Once you see that, “it was on sale” stops working on you.
Why people calculate it
- Before you buy.“Will this hit $2 a wear?” is a better filter than “is this $60?” — it forces a realistic picture of how often you'll actually reach for it.
- Before you re-buy.The duplicate detector catches it first: you already own four black tops, and their combined wear rate is 12%. The fifth one is not a wardrobe decision.
- While you cut back.No-buy challenges work when you can see the ledger. Watching a coat's CPW fall every week is the reward — shopping was just the more expensive hobby.
How Armoiria does it
Every item, every wear, no spreadsheets.
Armoiria counts the wears so the division takes care of itself.
Automatic wear tracking
Log an outfit once and every item in it gets credit. Your per-item wear count builds itself from your own mornings.
Cost per wear, per item
Enter a price when you add a piece (or import it) and CPW updates with every wear — plus closet value, utilization, and most-neglected rankings.
A monthly money dashboard
Spend versus wear, month by month: what came in, what actually got worn, and what's still wearing its price tag.
No-buy challenge streaks
Set a challenge, keep the streak alive, and watch cost-per-wear fall across the closet as existing clothes pick up the slack.
Know what your closet costs.
Catalog once, and the math runs for the rest of the year — per item, per month, per category.
