How it works

The Profit Margin Calculator helps you determine the financial health of your business by calculating three key profit margins: gross, operating, and net. The gross margin is calculated by subtracting the cost of goods sold (COGS) from total revenue and dividing by revenue. For instance, if your revenue is $500,000 and COGS is $250,000, the gross margin would be ($500,000 - $250,000) ÷ $500,000 = 0.5, or 50%. The operating margin further refines this by accounting for operating expenses. Here, you subtract both COGS and operating expenses from revenue. With operating expenses at $150,000, the operating income is $500,000 - $250,000 - $150,000 = $100,000, leading to an operating margin of $100,000 ÷ $500,000 = 0.2, or 20%. Finally, the net margin accounts for all expenses, including interest and taxes. After subtracting an interest expense of $10,000 and taxes of $15,000 from the operating income, the net income is $100,000 - $10,000 - $15,000 = $75,000, giving a net margin of $75,000 ÷ $500,000 = 0.15, or 15%.

Formula


                Gross margin = (Revenue − COGS) ÷ Revenue | Operating margin = Operating income ÷ Revenue | Net margin = Net income ÷ Revenue | Operating income = Revenue − COGS − OpEx
