### C. Step-by-Step Instructions for Calculating Gross Profit Margin

Here are the step-by-step instructions on how to calculate the gross profit margin:

- Calculate the total revenue for the period.

### D. Examples of Calculating Gross Profit Margin

Let’s illustrate how to calculate gross profit margin with two examples:

- Example 1: Company A has total revenue of $100,000 and cost of goods sold of $60,000.
- Gross profit = Total revenue – Cost of goods sold
- Gross profit = $100,000 – $60,000
- Gross profit = $40,000
- Gross profit margin = Gross profit / Total revenue x 100%
- Gross profit margin = $40,000 / $100,000 x 100%
- Gross profit margin = 40%
- Example 2: Company B has total revenue of $200,000 and cost of goods sold of $120,000.
- Gross profit = Total revenue – Cost of goods sold
- Gross profit = $200,000 – $120,000
- Gross profit = $80,000
- Gross profit margin = Gross profit / Total revenue × 100%
- Gross profit margin = $80,000 / $200,000 × 100%
