Count full cartons and the remainder

Divide the total pieces by the pieces in one carton. The whole-number result gives full cartons; the remainder is the loose-piece count.

250 ÷ 24 = 10 cartons + 10 pieces

If all pieces must be packed in cartons, round up: this example needs 11 cartons, with the last carton partly filled.

Working with pack sizes

Can products have different pack sizes?

Yes. Calculate each SKU and pack size separately. This tool does not combine unlike pack sizes or change actual stock records.

What about opened cartons?

Use Cartons → pieces, enter the full cartons, then enter the additional loose pieces. Total = cartons × pack size + loose pieces.

Worked example

Illustrative inputs and outputs to help you check your own task.

Pick a quantity from 12-piece cartons

Inputs
Choose Pieces → cartons, with 12 pieces per carton and 157 total pieces.
Output
13 full cartons and 1 loose piece. Packing all 157 pieces requires 14 cartons, with the last partly filled.

A partly filled carton is different from a full carton in the stock count.

Count full cartons plus an opened carton

Inputs
Choose Cartons → pieces. Enter 24 pieces per carton, 7 full cartons and 9 additional loose pieces.
Output
7 × 24 + 9 = 177 total pieces.

Repeat the calculation separately if another SKU uses a different pack size.
