How Is a Corrugated Box Price Calculated?
Dimensions are only the beginning. See how board area, paper GSM, printing and quantity shape the price of every box.
It starts with the flat sheet
A box is made from a single flat sheet of board, called a blank, that is cut, creased and folded. Manufacturers price the blank — not the volume of the box. For a regular slotted carton, the blank length is roughly twice the length plus twice the breadth plus a joint flap, and the blank width is roughly the height plus the breadth.
Board weight and paper grade
Multiplying the blank area by the board weight (GSM) gives the paper weight of each box. Higher-GSM kraft papers and more plies make a heavier, stronger box — and a more expensive one. Paper is the largest single cost in a corrugated box, typically well over half of the price.
A worked example
Take an 8 × 6 × 4 inch 3 ply box. The blank is about 30 inches long and 10.5 inches wide — roughly 0.2 square metres of board. At a board weight of 450 GSM, that is around 90 grams of paper per box. The paper cost per kilogram, plus a conversion charge for cutting, creasing and joining, gives the basic price per box.
Conversion and printing
Corrugating, cutting, creasing, stitching or gluing all add a conversion cost per box. Printing adds plate or setup charges plus a per-colour cost, which is why printed boxes are usually more economical at higher quantities, when the setup cost is spread across more boxes.
Why quantity matters
Machine setup time and wastage are spread across the whole order. That is why the price per box falls as quantity rises — a 1,000-box order costs noticeably less per box than a 100-box order of the same size. Our price list shows these quantity breaks for every stock size.
What else goes into a quotation
GST, freight to your location and any special requirements such as lamination, die-cutting, partitions or handles are added on top. A good quotation lists these clearly so you can compare suppliers like for like.
Getting an accurate price
Share the inner dimensions, ply, quantity, printing details and delivery pin code. Yamuna Packaging will quote a clear per-box price for your exact specification, usually with options at two or three quantity levels.
