Net Profit Margin Ratio

Net profit margin ratio (NPMR) is one of the profitability ratios and measures how much of each sales dollar is remaining after all costs are deducted. In other words it measures how successful the firm is in terms of its earnings on sales.

Net profit margin ratio (NPMR) = Net Profit/Sales

For example, if ABC has a net profit of $300,000 and sales of $3,000,000. The NPMR is calculated as follows.

= 300,000/3,000,000

= 0.1 or 10%
