How do you calculate palletizing rate?

Divide boards palletized by total boards presented. With 8 boards palletized out of 250 presented, the rate is 3.2%, which signals the station is rejecting nearly everything it sees.

What is the gap to target?

It is your yield target minus the actual rate. Against a 95% target, a 3.2% rate leaves a 91.8-point gap, telling you the palletizer is effectively down rather than just underperforming.

What is a good palletizing yield on a drywall line?

A healthy last-station yield usually sits above 98%, with most loss coming from genuine edge or corner damage. Anything in single digits means a mechanical fault or a counting error, not a quality problem.

Why is my palletizing rate so low?

A rate near 3% almost always points to a jam, a pattern fault, or a sensor miscount rather than real rejects. Confirm the presented count is right before chasing board quality.

Palletizing rate vs line yield?

Line yield covers the whole process from forming to dry end; palletizing rate isolates only the final stacking station, so you can tell whether losses happen upstream or at the load.

Does the presented count include damaged board?

Yes, total boards presented is everything that reaches the stacker, including damaged ones. That is intentional, so the rate reflects real shippable output, not just mechanical handling.

Palletizing Rate Calculator

At the end of a gypsum board line the bundles drop onto a stacker and the palletizer squares them into a load for the warehouse. Palletizing Rate measures the share of boards presented to that station that actually make it onto a clean, shippable pallet, as opposed to those rejected, hung up, or pulled for damage. Stacker operators and packaging engineers use it to catch a palletizer that is silently rejecting good board, and to size the gap between today's rate and the yield target the plant commits to. A low rate at the very last station wastes everything the line did upstream.

What this calculator does

Calculate palletizing success rate for a shift and compare it to your palletizing yield target.
Use it at a daily operations review to confirm the palletizer is meeting its yield target before the shipping dock window closes.
It divides boards successfully palletized by total boards presented to give a palletizing rate, then subtracts that from your yield target to show the gap in points.

Formula used

Palletizing rate = boards palletized / total boards presented
Gap to target = palletizing yield target - palletizing rate

Inputs explained

Boards palletized:
Total boards presented:
Palletizing yield target:

How to use the result

Use it during a stacker audit, after a palletizer changeover, or when finished-goods counts don't reconcile with line output.
It is a pure count ratio and says nothing about why boards fail to palletize, whether edge damage, a stacker jam, or a mis-set pattern.
