How do I calculate cost per wear?

Cost per wear = what you paid ÷ the number of times you've worn it: a 200 coat worn 40 times costs 5 a wear, and the more you wear it, the better value it gets. In Coday: log the piece as "One-off · Per use" and tap "Use once" on its page each time you wear it, and the cost per wear is worked out for you (Coday calls it cost per use). You can also set a Target avg and get reminded the day it gets there. Free, no sign-in needed.

How it's worked out

Cost per use = (price + additional costs − what you sold it for) ÷ times worn

Dry cleaning, alterations and anything else you spend on it count as additional costs and are spread in too.

How to log it in Coday

1. Add an item with its name, price and purchase date.
2. Set Pricing to "One-off · Per use", and if you've already worn it, enter how many times.
3. Save. After that, tap "Use once" on the item's page each time you wear it, or "Remove 1 use" if you tapped by mistake.

The item's page tells you how much one more wear will bring the cost down.

Set a target

Tap the Target avg chip at the end of the form and enter what you'd consider good value per wear, like 2. You're reminded on the day it pays off.

Per wear or per day?

For things you wear almost every day (work shoes, a winter coat), per day is easier to read, so choose "One-off · Per day". For things you wear on occasion (a suit, a formal dress, hiking boots), count by wear. The same goes for bags, rackets and camera lenses; see how cost per day, per use and per unit are calculated.
