1. What is Operating Income Percent?

Operating Income Percent (OI%), also known as Operating Margin, measures a company's operating efficiency by showing what percentage of revenue remains after covering operating expenses. It indicates how well a company generates profit from its core business operations.

2. How Does the Calculator Work?

The calculator uses the Operating Income Percent formula:

Where:

• \( Operating\ Income \) — Revenue minus operating expenses (USD)
• \( Revenue \) — Total sales or gross income (USD)
• \( 100 \) — Conversion to percentage

Explanation: This ratio shows the proportion of revenue that translates into operating profit, excluding non-operating items like interest and taxes.

3. Importance of Operating Income Margin

Details: Operating Income Margin is crucial for assessing a company's operational efficiency, comparing performance across companies and industries, and identifying trends in profitability over time.
