Cost Per Use Calculator

Add purchase price plus maintenance, accessories, subscriptions, and repairs — minus resale — then divide by projected uses to get the true cost per wear, wash, ride, or read. Uses are a projection, so the page treats them as an estimate to test, not a promise.

What your result means

Cost per use is the headline: every dollar of ownership divided by every projected use. Gross shows the full stack; net subtracts what resale gives back.

Because uses are a guess, treat the figure as a range: recompute with the lowest plausible count before deciding something is “cheap per use”.

How the calculation works

Add purchase price, maintenance, accessories, subscriptions, and repairs for gross ownership cost.
Subtract resale value for net ownership cost.
Divide net cost by projected uses for cost per use.

Formula

gross = price + maintenance + accessories + subscription + repair; net = gross − resale; per use = net ÷ uses

Grossprice + maintenance + accessories + subscription + repair
Netgross − resale value
Per usenet ÷ projected uses

Worked examples

Example: $200 boots, 100 wears, $40 resoling, $50 resale
price: 200uses: 100maintenance: 0accessories: 0subscription: 0repair: 40resale: 50
Result: Gross ownership cost $240.00 · Net ownership cost $190.00 · Cost per use $1.90
Example: $1200 bike + $200 gear, 500 rides, $400 resale
price: 1200uses: 500accessories: 200resale: 400
Result: Gross ownership cost $1,400.00 · Net ownership cost $1,000.00 · Cost per use $2.00

Assumptions

What this calculation takes for granted — check these before relying on the result.

Assumptions:

Default values are an example $200 item used 100 times — replace with your figures.
Uses are projected, not promised — rerun with low and high counts to bracket reality.
All extras are lifetime totals in today’s money; inflation and financing are ignored.
Resale assumes a working item sold in reasonable condition.

Limitations

Why your real figure may differ:

Projected usage is the weakest input: an item used half as often costs twice per use.
Time value of money, warranties, and hassle are excluded.
Resale markets move — optimistic resale flatters expensive purchases.
Shared or rented alternatives are not compared here.

Frequently asked questions

What counts as a “use”?

One wearing, ride, wash, read, or session — whatever consumes the item’s life. Pick the unit you can estimate most honestly and keep it consistent when comparing options.

Gross vs net ownership cost?

Gross is everything you spend. Net subtracts resale — the fairer figure when comparing a quality item you can resell against a disposable one you cannot.

How do I handle uncertain usage?

Compute three figures: pessimistic, realistic, and optimistic uses. If the expensive option only wins on the optimistic count, it is a gamble, not a bargain.

Should subscriptions count?

Yes, as lifetime totals — a $10/month companion app over three years adds $360, which often flips the “cheap” option.
