How to use this calculator

  1. Choose one use: a wear, a trip, a session or a completed job. Keep that definition consistent.
  2. Enter the full purchase cost and total upkeep for the period you expect to own it.
  3. Enter a cautious resale estimate and the total number of uses; calculate, then test fewer uses and zero resale.

The formula

Cost per use = (purchase + lifetime upkeep − net resale proceeds) ÷ lifetime uses

Add costs over one ownership period, then subtract the amount you expect to recover on sale. Divide by uses over that same period. Upkeep is a lifetime total, not an annual figure. The no-resale result shows the effect of receiving nothing when you stop using the item.

PUTTING IT INTO PRACTICE

A worked example

A 300 purchase with 60 total upkeep and 40 net resale proceeds costs 320 over its life. At 160 uses, that is 2.00 per use. At only 80 uses, the same ownership cost becomes 4.00 per use.

How to interpret your result

Compare products that deliver a similar service. A lower number based on optimistic use can be less informative than a higher number supported by an actual usage record.

Assumptions and limitations

All amounts use one currency. Costs and uses cover the same period. Uses must be a positive whole number; resale cannot exceed purchase plus upkeep in this model.

No financing, discounting, inflation or guaranteed durability. Time, storage space and performance are not valued. A low cost per use does not establish affordability. Collectibles with gains above total costs are outside this cost-only model.

Common questions

Is this price per unit?

No. Price per unit compares package quantities at purchase. Cost per use spreads a durable item’s ownership cost across repeated uses.

Can I use cost per wear?

Yes. Count wears across the entire ownership period, include cleaning or repairs if material, and use the same definition for each item.

What if I never use it?

Cost per use is undefined at zero uses. The calculator rejects zero instead of suggesting a free or zero-cost purchase.

Should I include tax?

Include the tax and delivery amounts you actually expect to pay in purchase cost. No local tax rate is inferred.
