How This Calculator Works
Scrap Cost = Scrapped Units × (Material + Labour + Overhead)
Rework Cost = Reworked Units × Rework Cost/unit
Total COPQ = Scrap Cost + Rework Cost
COPQ (Cost of Poor Quality) typically runs at 5–20% of total revenue in manufacturing. Even a 1% reduction in rejection can save lakhs per year.

The Hidden Costs of Poor Quality
The visible cost of scrap — the material you throw away — is just the tip of the iceberg. Hidden costs include: inspector and sorter time, machine time wasted on bad parts, rescheduling, expediting replacements, customer complaints, warranty claims, and reputational damage. Studies show that hidden quality costs are typically 3–10× the visible scrap material cost.
