The net profit margin is calculated by subtracting total expenses from total revenue, dividing the result by total revenue, and then multiplying by 100 to get a percentage. The formula is:
Net Profit Margin = ((Total Revenue – Total Expenses) / Total Revenue) * 100
This percentage represents how much profit you are making from each dollar of revenue after all expenses are accounted for. For example, if your total revenue is $20,000 and your total expenses are $15,000, the net profit margin would be 25%. This means that for every dollar you make, you retain 25 cents in profit after covering all costs.
