Operating profit margin ratio (OPMR) is a profitability ratio. It measures how much of each sales dollar remains after all costs, after interest, tax and preferred stock dividends are deducted. In other words it measures how efficiently a business manages its operations or how efficiently the firm manages its income statement (keeping a healthy balance between sales and costs).

Operating profit margin ratio (OPMR) = Operating Profit/Sales

Example

For example, if ABC Company has operating profit of $500,000 and sales of $3,000,000 then Operating profit margin ratio (OPMR) is calculated as follows:

= 500,000/3,000,000

= 0.167 or 16.7%
