A factory produces 1,200 widgets per day. If 2.5% are defective and the factory operates 22 days per month, how many non-defective widgets are produced monthly?

In today’s world of manufacturing and quality assurance, even small flaws can impact daily output and overall efficiency. A typical factory churns out 1,200 widgets each day, but with a 2.5% defect rate, understanding how many flawless units actually leave the line matters for both producers and consumers tracking quality trends. This routine calculation reveals the real impact of quality control in manufacturing—something increasingly discussed across supply chains and product safety circles in the U.S.

Why This Calculation Matters in Current Industry Conversations
With rising awareness about product reliability, inspection rates, and waste reduction, knowing how many non-defective widgets emerge daily offers valuable insight into factory performance. It reflects not only quality standards but also operational efficiency and resource management—factors closely watched by businesses aiming to improve sustainability and profitability. As quality-conscious consumers and corporate buyers seek greater transparency, precise math underpinning production metrics drives smarter decisions across manufacturing sectors.

Understanding the Context

How the Numbers Add Up
Each day, 1,200 widgets are produced, with 2.5% failing quality checks—equaling 30 defective units (2.5% of 1,200). Subtracting this from the daily output results in 1,170 non-defective widgets per day. Over 22 operating days in a month, the total non-defective output reaches 25,740 units (22 × 1,170)—a clear picture of actual market-ready production after accounting for quality loss.

Common Questions About Defect Rates and Monthly Output
Q: How are defective widgets accounted for in monthly totals?
A: By identifying the percentage defective (2.5%) and subtracting it from the daily production before multiplying by operating days. This formula ensures accurate, transparent reporting.
