Cost per wear measures how much use you got from an item; resale value estimates what it might sell for. A garment can be excellent value to wear and still have little resale demand. Keep the two measures separate.
Calculate use without guessing a sale price
The simple formula is purchase cost divided by recorded wears. State whether you include alterations or cleaning, and apply that choice consistently. If your wear history is incomplete, label the result approximate rather than presenting an exact lifetime figure.
Stylebook publishes cost-per-wear guidance and offers wear-related tools. Pieces focuses on ownership, purchase costs and market evidence; this guide does not imply that Pieces automatically logs your daily wears.
Compare the questions each number answers
| Measure | Useful question |
|---|---|
| Cost per wear | How much has each recorded use cost me? |
| Purchase cost | What did I spend acquiring this item? |
| Market estimate | What range does available comparable evidence suggest? |
| Net sale proceeds | What remains after the sale's actual expenses? |
Work through a simple example
Illustrative arithmetic: a coat cost $300 and has 60 recorded wears. Its simple cost per wear is $5. If comparable used sales suggest a $100 gross sale, that does not retroactively change what you paid or the number of wears. If selling expenses are $20, net proceeds would be $80 and the purchase-to-sale difference would be a $220 loss.
That loss does not mean the coat failed as clothing. Conversely, a rarely worn jacket with a high listing ask has not paid for itself. Usage satisfaction and resale returns are different decisions.
Decide whether to keep or sell
- Check whether you still use the piece and whether it fits its purpose.
- Separate known wears from guesses.
- Research the actual version and condition if a sale is realistic.
- Compare likely net proceeds with the value of continuing to use it.
- Keep your original purchase record regardless of the decision.
There is no universal cost-per-wear target that makes every purchase sensible. Frequency, occasion and durability differ. Avoid importing another collector's threshold as a rule for your wardrobe.
Use Pieces for collection records and available market estimates, and a separate wear log if you need that measurement. Read collection P&L for the distinction between a paper gain and an actual sale.
