Packaging first-pass yield calculator

Calculate first-pass yield, rework rate and scrap rate for a packaging or production process.

Production environment relevant to packaging first-pass yield calculator

What this calculator does

First-pass yield measures the proportion that meets the agreed finished-pack standard without rework. Enter total units, first-pass good units, reworked units and scrapped units to expose hidden quality loss.

Checks before using the result

  • Define the process boundary
  • Define “good without rework” objectively
  • Count rework even when it later becomes saleable
  • Reconcile good, rework and scrap quantities
  • Separate failure modes by reason
  • Review FPY by product and format
  • Confirm data capture at the point of loss

Calculator questions

Questions customers also ask

What is first-pass yield?

It is the number of units accepted without rework divided by the total entering the defined process.

Should reworked units count as good?

Not for first-pass yield. They can count in final yield after rework, but FPY exposes the original process loss.

Can FPY exceed final yield?

Normally no. Final yield may be higher after successful rework, while FPY remains the original first-pass result.

Why track scrap separately?

Rework and scrap have different causes and costs. Separating them makes corrective action and cost analysis more useful.
