What is cost per use?

Cost per use is the purchase price divided by the number of times you actually use an item. A 200 coat worn 100 times costs 2 per wear; the same coat worn twice costs 100 per wear. It reframes a sticker price around real-world value.

How do I calculate cost per use?

Divide the price by the total number of uses. If you expect to resell the item, subtract the resale value first: cost per use = (price − resale value) ÷ total uses. You can give total uses directly or as uses per week times the number of weeks you keep it.

What is the cost-per-wear rule?

Cost per wear is the same idea applied to clothing: a more expensive item you wear constantly can be better value than a cheap one you wear once. Comparing cost per wear, rather than price alone, often favours durable items you use a lot.

Should I always buy the lowest cost per use?

It is a strong value signal but not the only factor. Quality, how long the item lasts, storage, and whether you will genuinely use it all matter. A low projected cost per use only holds if you actually use the item as often as you assumed.

The Cost Per Use Calculator reframes a price tag around how much you will actually use something — the simple test that often reveals whether an expensive, durable item is better value than a cheap one you barely touch.

The formula

cost per use = (price − resale value) ÷ total uses

A 200 coat worn 100 times costs 200 ÷ 100 = 2 per wear. Worn just twice, it costs 100 per wear. If you expect to sell it later, subtract the resale value first so you only count what the item really cost you.

Two ways to count uses

Total uses — enter the number directly if you know it.
Per week × weeks kept — for example 3 times a week for 104 weeks (two years) is 312 uses.

Worked examples

Item	Price	Uses	Cost per use
Running shoes	120	300	0.40
Winter coat	200	100	2.00
Party dress	90	2	45.00
Espresso machine	500	1,000	0.50

The cheapest sticker price is not always the best value: a durable item you use constantly can cost far less per use than a bargain you use once. The projection only holds if you really use the item as often as you assume.
