Cost Per Use Calculator

The sticker price doesn't tell you if something's worth it — the cost per use does. Enter the price, how often you'll use it, how long you'll keep it, and any resale value, and you'll see what each use really costs. Great for "buy cheap vs buy quality" decisions. Updates as you type.

How to use it

cost per use = (price − resale value) ÷ (uses per week × weeks kept)

• Compare two options by running each — the lower cost per use is usually the smarter buy, even if it costs more upfront.
• Be honest about uses. The number-one budgeting mistake is overestimating how often you'll use something.
• Count resale for things that hold value (phones, tools, quality goods); leave it at zero for consumables.

This is an educational estimate to help compare purchases. It ignores running costs, maintenance and the time value of money. Not financial advice.

FAQ

What is cost per use?

Cost per use is the price of an item divided by the number of times you actually use it over its life. A $200 coat worn 300 times costs about $0.67 per wear, while a $40 gadget used twice costs $20 each time. It is a far better way to judge value than the sticker price alone.

How do I calculate cost per use?

Take the price, subtract any resale or trade-in value you expect to recover, then divide by the total number of uses. Total uses = uses per week × weeks you keep it. The calculator does this instantly and lets you change any input.

Why is cost per use better than the sticker price?

Because a higher price can be the better deal if you use the item far more. Buy-it-for-life items often have a low cost per use despite a high upfront price, while cheap impulse buys you rarely touch can be expensive per use. Comparing cost per use stops you over-valuing the headline number.

Should I include resale value?

If you realistically expect to sell or trade the item later, subtract that amount — it lowers the true cost. Many things (phones, cars, quality tools, designer goods) hold meaningful resale value. Leave it at zero for items you will use up or throw away.
