A profit margin calculator shows what share of your revenue remains after costs. Enter revenue and costs for the same period to calculate gross, operating, or net margin. The result is a percentage you can use to check pricing and see where profit is being reduced.<\/p>\n

What does a profit margin calculator do?<\/h2>\n

It turns revenue and cost figures into margin percentages. Here\u2019s an illustrative monthly service-business example you can replicate with your own numbers.<\/p>\n

What you enter:<\/strong><\/p>\n\n\n\n\n\n\n\n
You enter<\/th>\nAmount<\/th>\n<\/tr>\n<\/thead>\n
Revenue<\/td>\n$50,000<\/td>\n<\/tr>\n
Direct delivery costs<\/td>\n$28,000<\/td>\n<\/tr>\n
Operating expenses<\/td>\n$12,000<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

What the calculator shows:<\/strong><\/p>\n\n\n\n\n\n\n\n\n\n
The calculator shows<\/th>\nCalculation<\/th>\nResult<\/th>\n<\/tr>\n<\/thead>\n
Gross profit<\/td>\n$50,000 \u2212 $28,000<\/td>\n$22,000<\/td>\n<\/tr>\n
Gross margin<\/strong><\/td>\n$22,000 \u00f7 $50,000<\/td>\n44%<\/strong><\/td>\n<\/tr>\n
Operating profit<\/td>\n$22,000 \u2212 $12,000<\/td>\n$10,000<\/td>\n<\/tr>\n
Operating margin<\/strong><\/td>\n$10,000 \u00f7 $50,000<\/td>\n20%<\/strong><\/td>\n<\/tr>\n
Net margin<\/strong><\/td>\n$10,000 \u00f7 $50,000<\/td>\n20%<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The net margin result assumes no interest, taxes, or other non-operating items. If any apply, net income, and net margin, will differ from operating profit.<\/p>\n

How do you use a profit margin calculator?<\/h2>\n
    \n
  1. Choose a period.<\/strong> Use a complete month, quarter, or year. Match every input to that period.<\/li>\n
  2. Enter revenue.<\/strong> Use consistent revenue figures, generally excluding sales taxes collected for a tax authority and adjusting for returns or discounts.<\/li>\n
  3. Add direct delivery costs.<\/strong> Include costs associated with providing the service, classified consistently in your records.<\/li>\n
  4. Enter operating expenses.<\/strong> Include business-running costs not counted as direct delivery costs.<\/li>\n
  5. Check the output.<\/strong> Compare gross and operating margin. Calculate net margin using net income after all relevant expenses.<\/li>\n<\/ol>\n

    For a service business, direct delivery costs may include labor tied to client work, subcontractors, and job-specific materials. Classification depends on your accounting and management reporting policies. The OpenStax overview of the income statement<\/a> explains how revenue, direct costs, operating expenses, and net income fit together.<\/p>\n

    What formulas does a profit margin calculator use?<\/h2>\n

    A margin is profit divided by revenue, expressed as a percentage. Use the same period and revenue basis throughout.<\/p>\n
