About ShelfCalc

ShelfCalc is a small, independent site of free pricing calculators for people who run stores: owners, managers, buyers, and anyone who buys by the case and sells by the unit.

Each calculator does one job and shows its work. You'll find the formula, a worked example and the questions people usually ask next on every page, so you can trust the number or catch it if something looks off.

How the calculators handle your numbers

Everything is calculated in your browser. Nothing you type is sent to a server or stored. Close the page and it's gone.

How the site is paid for

ShelfCalc is free to use and supported by ads. Ads never change how a calculator works or what it tells you.
