Cost of Quality Formula
It can further be expressed as displayed below: –
Here,
- The cost of good quality is represented as CoGQ.
- The cost of poor quality is represented as CoPQ.
- The prevention cost is represented as PC.
- The appraisal costs are represented by AC;
- The internal failure costs are represented by IFC.
- The external failure costs are represented by EFC.
Example of Cost of Quality
Let us take the example of a business that generates $1,000,000 in sales. It incurs $10,200 in Quality checks and inspection. It pays $30,000 for appraising the purchased raw materials. Additionally, it pays $15,000 for repairs on finished items. It maintains a provision of $5,000 for warranty costs and product returns. Help the management determine the cost of quality as the percentage of sales.
Solution:
Step 1: Calculation of Total CoGQ
=$10200+$30000
=$40200
Step 2: Calculation of Total CoPQ
=$15000+$5000
=$20000
Step 3: Calculation of Total CoQ
=$20000+$40200
=$60200
Step 4: Calculation of cost of quality as the percentage of sales
=$60200/$1000000
=6.02%
Here, the inspection checks and appraisal costs on raw materials account for the CoGQ. The costs of repairs, warranty costs, and product returns account for the CoPQ.
Why Measure the Cost of Quality?

Difference Between Cost of Quality and Cost of Poor Quality
- The cost of poor quality (CoPQ) is a subset of the cost of quality.
- The CoPQ is the business cost incurred when the defective products are identified before and after shipping to customers.
- Therefore, the sum of internal and external failure costs can be termed as the CoPQ.
- The CoPQ usually consists of product return costs and warranty costs related to the products.
- The cost of quality, on the other hand, is determined as the CoGQ and CoPQ.
- It is determined as the sum of the cost of good quality and poor quality.
- The cost of quality takes into account prevention costs, appraisal costs, internal failure costs, and external failure costs.
- The prevention costs and appraisal costs do not constitute the CoPQ as such costs attempt to identify defective products at the beginning of the production process.
- The CoPQ arises after the end of the production process and on defective finished goods.
Benefits
