How This Calculator Works
Scrap % per Line = Scrap Units ÷ Total Units × 100
Line Monthly Cost = Scrap/Day × Cost/Unit × Working Days
Overall Scrap % = Total Scrap ÷ Total Units × 100
Focus improvement on the worst-performing line first — it gives the biggest absolute saving.

Using Multi-Line Waste in Daily Production Meetings
Enter the previous day's data for each line in your morning stand-up. The worst line is immediately visible — assign a corrective action owner and a target for the next day. Tracking this daily creates accountability and makes quality improvement a team habit rather than a monthly report.
