Understanding Your Margins

Gross margin measures profitability after direct costs. Net margin measures what remains after operating costs, interest, and taxes.

  • Operating margin shows how much of each revenue dollar remains after direct costs and day-to-day operating expenses, before financing and taxes.
  • Markup compares gross profit to direct costs, which is different from gross margin, which compares gross profit to revenue.
  • Return on assets and equity compare net income to the resources invested in the business.
Where Do I Find These Numbers?(show)
  • Revenue, direct costs, operating expenses, interest, and taxes: Generally shown on the profit and loss (income statement) report in your accounting software.
  • Total assets and owner equity: Generally shown on the balance sheet report.
