What is cost per use?

Cost per use is the price of an item divided by the number of times you expect to use it over its life. It shows the real value of a purchase better than the sticker price alone.

Why does cost per use matter?

A more expensive item used often can be far better value than a cheap one barely touched. Cost per use helps you decide between buying cheap and buying well.

What can I use this for?

Anything from appliances and tools to clothing and a gym membership. Compare two options on cost per use to see which genuinely gives better value for how you will use it.

Cost Per Use Calculator

This New Zealand calculator helps you judge whether a purchase is good value by working out what it really costs each time you use it, a simple but powerful way to think about spending. You enter the price of an item and how often you expect to use it over its life, and the tool calculates the cost per use, revealing that an expensive item used constantly can be better value than a cheap one barely touched. The breakdown shows the total cost, the expected uses, and the cost per use, helping you decide between buying cheap and buying well, and bring a clear-eyed perspective to purchases from appliances to clothing to gym memberships.

Be honest about how often you will really use something, since that is what drives the value. A higher price spread over many uses can easily beat a cheap item used a handful of times. General information to support a buying decision.

How it works

The calculator divides the price by the number of times you expect to use the item over its life to give the cost per use. Comparing two options on this basis shows which genuinely offers better value for how you will actually use it. The lower cost per use wins, which often means a well-made item used regularly beats a cheap one that sits unused.

Worked example

A $300 item you will use 200 times costs $1.50 per use. An $80 alternative used only 20 times costs $4 per use. Despite the much lower price, the cheaper item is worse value here, because it will be used so little. The cost per use makes that clear.
