Operating Profit Margin Formula

Formula
$$\text{Operating Profit Margin} = \left( \frac{\text{Operating Income}}{\text{Revenue}} \right) \times 100$$

Explanation:
Operating profit margin expresses operating income (revenue minus operating expenses) as a percentage of total revenue. It shows how efficiently a company turns revenue into profit before interest and taxes.

This metric is a vital tool for business owners, investors, and analysts to assess a company’s core profitability. It excludes non-operating items like interest and taxes, giving a clear view of operational performance.

Example Variables:

  • Operating Income: $250,000
  • Revenue: $1,000,000
  • Operating Profit Margin = (250,000 / 1,000,000) × 100 = 25%

Use Cases:

  • Comparing business units or competitors
  • Tracking performance trends over time
  • Preparing for investment or acquisition analysis
