Frequently Asked Questions
What is cost per use?
Cost per use is the total purchase price of an item divided by the number of times you use it. It helps evaluate the true value of a purchase beyond sticker price. A $200 winter coat worn 100 times costs $2.00 per use. A $50 fast-fashion coat worn 10 times costs $5.00 per use. The pricier coat is actually cheaper per use. This principle — often called 'cost per wear' in fashion — applies to any reusable item: kitchen appliances, gym equipment, tools, bags, shoes, and more.
How do I calculate break-even against an alternative?
Break-even occurs when the total cost of the alternative equals the purchase price of the item. Formula: Break-Even Uses = Item Cost ÷ Alternative Cost Per Use. Example: A $120 reusable water bottle vs. $1.50 disposable bottles. Break-even = $120 ÷ $1.50 = 80 uses. After 80 uses, the reusable bottle costs less total than buying disposable bottles. After 200 uses, the reusable bottle costs $0.60/use vs. $1.50 for disposables — a 60% savings.
What is a good cost per use?
There is no universal threshold — it depends on the category. Clothing: under $5/wear is generally good, under $2/wear is excellent. Coffee maker: $500 / 1,000 uses = $0.50/cup (vs. $4–$6 at a café — excellent value). Gym equipment: $500 treadmill / 200 uses = $2.50/session (vs. $30–$60 gym day pass — excellent). The key is to be realistic about estimated uses. Over-estimating uses is the most common mistake — be conservative, especially for aspirational purchases.
How does this apply to clothing (cost per wear)?
Cost per wear is a popular budgeting concept in sustainable fashion. High-quality, versatile pieces worn frequently often cost less per wear than cheap trendy items worn once or twice. Example: $400 leather boots worn 200 times = $2/wear. $40 fast-fashion boots worn 5 times = $8/wear. However, this only holds if you actually wear the item. The most expensive clothing is what hangs in your closet unworn — factor in real-world usage, not aspirational usage, when evaluating purchases.
