Quality calculator
Scrap Cost Calculator
Convert rejected units into a clear dollar impact for the run and for every good part shipped.
What this calculator does
- Estimate the real dollar impact of scrap, rework, and yield loss.
- Use when quality losses need a number attached.
- Estimate the real dollar impact of scrap, rework, and yield loss.
Formula used
- Scrap rate = scrap units ÷ total units
- Total scrap cost = scrap units × loss per unit
- Cost per good part = scrap cost ÷ good units
Inputs explained
- Total units produced: undefined
- Scrap units: undefined
- Material cost per unit: undefined
- Labor cost per unit: undefined
- Rework / disposal per scrap: undefined
How to use the result
- Use when quality losses need a number attached.
- This is a planning calculator. Validate assumptions against your process data before using the result as a final quote, schedule, or engineering decision.
Common questions
- Which inputs usually drive the scrap cost result? total units produced, scrap units, material cost per unit, labor cost per unit, and rework / disposal per scrap usually have the biggest effect. When one of those assumptions changes, rerun the calculator and compare the new $ / run result before updating the plan.
- What does the scrap cost calculator do? Estimate the real dollar impact of scrap, rework, and yield loss.
- What inputs do I need for the scrap cost calculator? You need total units produced, scrap units, material cost per unit, labor cost per unit, and rework / disposal per scrap. Use measured values from your line, quote package, supplier data, or current production plan whenever possible.
- How should I interpret the scrap cost result? Treat the $ / run output as a planning estimate for quality work. Compare it against process history, quoted assumptions, and operating limits before making final decisions.
