1. What is Operating Profit Margin?

Operating Profit Margin (OPM) is a profitability ratio that measures what percentage of a company's revenue is left over after paying for variable costs of production. It shows how efficiently a company is managing its operations and generating profits from its core business activities.

2. How Does the Calculator Work?

The calculator uses the Operating Profit Margin formula:

Where:

• \( Operating\ Profit \) — Revenue minus operating expenses (also called EBIT)
• \( Net\ Sales \) — Total revenue minus returns, allowances, and discounts

Explanation: The formula calculates the percentage of revenue that remains as operating profit after accounting for all operating expenses.

3. Importance of OPM Calculation

Details: Operating Profit Margin is crucial for assessing a company's operational efficiency, comparing performance across companies and industries, and identifying trends in profitability over time. A higher OPM indicates better cost control and operational effectiveness.

4. Using the Calculator

Tips: Enter operating profit and net sales in the same currency units. Both values must be positive, and net sales cannot be zero. The result shows the operating profit margin as a percentage.

5. Frequently Asked Questions (FAQ)

Q1: What is a good Operating Profit Margin?

Q4: Can OPM be negative?
