Cost Per Use Calculator
Calculate the true cost per use of any purchase — clothes, gadgets, gym equipment. Justify a splurge or spot a bad deal.
How to use this tool
- Enter the total purchase price.
- Estimate how many times you will use the item.
- See the cost per use — the lower, the better value.
Calculate the real cost per use to decide whether a purchase is genuinely good value.
Formula
Cost per use = purchase_price ÷ number_of_uses
How it works
This calculator divides the total purchase price of an item by the number of times it will be (or has been) used, yielding the effective cost of each individual use. The result helps compare the value of different purchases on a like-for-like basis — a higher-priced item used frequently can be cheaper per use than a low-priced item rarely used. Accuracy depends on an honest estimate of actual usage; sunk costs and resale value are not included.
Worked example
Worked example
- Purchase price = $200 (e.g. a piece of gym equipment)
- Number of uses = 100
- Cost per use = $200 ÷ 100 = $2.00
Cost per use: $2.00
Key terms
- Cost per use (CPU)
- The effective price of each individual use of a purchased item, calculated by dividing the purchase price by the number of uses.
- Cost-per-use analysis
- A method for evaluating whether an item provides good value by measuring its real-world cost relative to how often it is actually used.
- Sunk cost
- Money already spent that cannot be recovered; not factored into cost-per-use but relevant when deciding whether to continue using or discard an item.
- Amortisation
- The spreading of a cost over a period or number of events; cost per use is a simple form of amortisation applied to individual items.
Frequently asked questions
- What is cost per use?
- Cost per use = price ÷ number of uses. A $200 coat worn 100 times costs $2 per wear — better value than a $50 coat worn 5 times ($10 per wear).
- How do I estimate number of uses?
- Think about frequency (weekly, monthly) and expected lifespan. A daily-use item lasting 2 years = ~730 uses; a gym bag used 3× a week for 3 years = ~468 uses.
