1. What is Material Yield vs Scrap?

Material yield measures the percentage of good units produced compared to the total units started, while scrap represents the percentage of units that didn't meet quality standards. These metrics are crucial for manufacturing efficiency and cost control.

2. How Does the Calculator Work?

The calculator uses these simple formulas:

Where:

• \( Good \) — Number of acceptable units produced
• \( Total \) — Total number of units started

Explanation: The yield percentage shows production efficiency, while scrap percentage shows waste. Higher yield means better utilization of materials and resources.

3. Importance of Yield Calculation

Details: Tracking yield helps identify production issues, reduce waste, improve quality control, and optimize manufacturing processes for better profitability.

4. Using the Calculator

Tips: Enter the count of good units and total units produced. Both values must be positive numbers, and good units cannot exceed total units.

5. Frequently Asked Questions (FAQ)

Q1: What's considered a good yield percentage?
A: This varies by industry, but generally >90% is good, >95% is excellent, and <85% may indicate production issues.

Q2: How can I improve my yield?
A: Common strategies include better quality raw materials, improved process control, operator training, and preventive maintenance.

Q3: Should I track yield by production run?
A: Yes, tracking yield by run, shift, or batch helps identify specific problems and measure improvement efforts.

Q4: What's the difference between scrap and rework?
A: Scrap is unusable material that must be discarded, while rework can be repaired or reprocessed to meet standards.

Q5: How does yield affect costs?
A: Lower yield means higher per-unit costs as fixed costs are spread over fewer good units and material waste increases.
