Earnings before interest & tax (EBIT). The Operating Profit Calculator takes revenue, cost of goods sold, operating expenses and returns operating profit (ebit) plus operating margin, gross profit. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Margins tell you where the money goes between revenue and profit. Track each margin over time and against similar businesses; a falling margin while revenue grows is the signal to investigate. Use the worked example below to check the maths against your own figures.
