Cost per use & wear value calculator

The price of something tells you little about whether it is good value — a costly item used daily for years can be cheaper per use than a bargain that sits unused. This calculator computes the true cost per use (or per wear, or per day) by dividing the purchase price, plus any maintenance costs, across how often and how long you actually use the item.

Reframing a purchase this way cuts through both false economy and buyer’s remorse. A durable, frequently used item reveals itself as excellent value even at a high price, while an expensive impulse buy that is rarely used exposes its real cost. The tool turns “is this worth it?” into a concrete number.

It runs in your browser, so your figures stay private. Use it to justify (or reconsider) a purchase, compare a cheap-but-flimsy option against a durable one, or decide whether an upgrade earns its price through use.
