Cost per use

Cost Per Wear, Applied to Everything You Own

Fashion worked this out decades ago. The idea is far more useful outside the wardrobe than in it.

Cost per wear is usually presented as a fashion trick: divide the price of a jacket by the number of times you wear it. It is useful, but the idea is bigger than clothing.

The same calculation works for almost anything. A tool, kitchen appliance, piece of furniture, subscription or pair of headphones can all be understood by asking one plain question: how much use did I get for what I paid?

The answer will not make every decision obvious. It will make the difference between cheap and good value much easier to see.

The calculation is simple

Take the amount you paid and divide it by the number of meaningful uses.

A $180 coat worn 60 times costs $3 per wear. A $30 shirt worn once costs $30 per wear. For a sofa used daily over five years, the useful unit may be days, months or years instead.

The unit does not need to be perfect. It needs to be consistent enough to compare two options. If counting every use would be annoying, choose cost per month, year or project.

Choose the unit that matches the object

Clothing is easy to count by wear. For a drill, cost per project may be more useful. For a desk, cost per year makes sense. For a slow cooker, you might count meals made. For a subscription, you could count months used.

Some objects have several kinds of use. A dining table might be where you eat, work and have conversations. You do not need to split the value into exact categories. If it is doing useful work regularly, note that. If it is mainly taking up space, note that too.

The first use can be misleading

A new purchase often feels valuable before it has earned that feeling. It is clean, available and full of possibility. You imagine the meals it will make, the jobs it will finish or the occasions you will wear it for.

Cost per use becomes meaningful over time. A cheap item that does not fit your routine can still be expensive per use. A more expensive item may become inexpensive if it solves a regular problem without needing replacement.

This is also why an "investment piece" is not automatically a good investment. It has to be used, and it has to remain useful to you.

Use the number before you buy

You can estimate cost per use before buying, but keep the estimate modest.

Ask how often you will use the thing in an ordinary week or month, not during the ideal version of your life. For camping equipment, think about trips you actually take. For formal clothes, count occasions already in your calendar.

Then ask what would need to be true for the purchase to earn its place. Would it need to last three years, be used every weekend or replace something you own? If those conditions sound unlikely, the price tells you less than you think.

Record what really happened

The most useful calculation happens after the purchase, when you know what it actually did.

When something leaves, write down roughly what it cost, how long you had it and how often you used it. "Most weekends for two years" is enough. If you would not buy it again, add the reason.

Cost per use is not a demand that everything be maximised. It is a way to notice when the story at checkout did not match what happened afterwards.
