Choose the ply (3, 5, 7 or 9) and enter the box size. Set the GSM and rate for each paper layer, plus your conversion, printing and margin.
Tap Calculate Box Rate. You instantly see sheet size, sheet weight, paper cost, conversion cost and the final selling price per box.

The app is free and supported by ads. If you would rather work without them, a small monthly plan removes every ad from the app — on all your devices with the same login.
