How the cost per use calculator works

The idea is simple. A high price is easier to justify when you use something often and for a long time. This tool spreads the purchase price, plus any weekly running costs, across the total number of times you expect to use the item. The result is a clear per use figure you can compare against cheaper alternatives.

Total uses is your uses per week multiplied by the weeks you plan to keep it. Total cost is the price plus running costs over that same period. Divide one by the other and you have your cost per use.

A quick example

Buy a $120 pair of boots, wear them 3 times a week and keep them for 2 years, which is 104 weeks. That is 312 wears for $120, or about $0.38 a wear. A $40 pair worn only a handful of times before falling apart can easily cost more per wear.

Things to keep in mind

Be honest about how often you will really use something, since optimistic estimates make every purchase look like a bargain. For broader budgeting help, browse our other free calculators.

Frequently asked questions

What is cost per use?

Cost per use is the total cost of owning something divided by how many times you use it. A $120 jacket worn 100 times costs $1.20 per wear, while the same jacket worn twice costs $60 per wear. It is a simple way to judge whether a purchase is good value.

How is cost per use calculated?

Add the purchase price to any running costs over the time you keep the item, then divide by the total number of uses. Total uses is your uses per week multiplied by the number of weeks you expect to own it.

Why include running costs?

Some items have ongoing costs such as maintenance, subscriptions or consumables. Including a weekly running cost gives a more honest picture of what each use truly costs, not just the sticker price.

How can I lower my cost per use?

Use the item more often or keep it longer, since both raise the number of uses you spread the price across. Buying durable items you will actually use frequently is usually better value than rarely used bargains.
