Cost Per Use: A Smarter Way to Compare Purchases

The aim is to offer a method you can adapt to your own situation, not a one-size-fits-all answer. Gather relevant information, check assumptions and revisit the plan when something changes.

Calculate a baseline

Divide purchase price by the number of times you expect to use the item. A $90 item used 90 times costs $1 per use before maintenance. This is not a guarantee that the item is worth buying; it makes assumptions visible.

Make usage estimates honest

Think about similar items you own and how often you used them. A product bought for an imagined project may sit unused, while a tool replacing frequent rentals might be used often. Consider storage, cleaning, setup and routine fit.

Compare alternatives

A low-cost item with a short life may have a higher cost per use than a durable item. A premium item may not be better value if extra features are rarely used. Compare like-for-like functions and check warranty, repairability and consumables.

Include ongoing costs

If an item needs subscriptions, batteries, filters, parts or maintenance, include these in the total before dividing by use. For a service, include fees and additional usage charges relevant to your expected use.

Consider renting or borrowing

Borrowing, renting or buying second-hand may be better for occasional use. Use cost per use alongside safety, convenience, quality and the cost of not having the item.

Quick checklist

• Write down the values and units you are using.
• Separate estimates from confirmed costs and requirements.
• Check official, current information for final decisions.
• Keep a record so you can update the estimate later.
