net margin · noun

Net profit as % of revenue.

"A 5% net margin looked thin until you saw the volume behind it."

Definition in plain terms

Net margin (net profit margin) is net income divided by revenue, as a percentage. Net income is the true bottom line — what remains after every expense: cost of goods, operating costs, interest, taxes, and one-off items. Net margin says how many cents of each sales dollar the company actually keeps as profit.

The mechanics

Net margin = net income ÷ revenue × 100. It sits at the bottom of the income statement, below gross and operating margin, because it subtracts everything. That completeness is its strength and its weakness: it captures the full picture but is also swayed by financing choices, tax rates, and one-time gains or charges that don't reflect ongoing operations.

When it matters

Net margin matters as the ultimate profitability check and for comparing the bottom-line efficiency of companies. But it should be read alongside gross and operating margin: a healthy net margin built on a one-off tax benefit is not the same as one built on strong operations. Industry context is essential — high-volume, low-margin businesses can be excellent.

Worked example. A grocery chain runs a 2% net margin — it keeps two cents per sales dollar after everything. That sounds thin next to a software firm's 25%, but on enormous volume it's a strong, stable business. Reading net margin alone would dismiss the grocer; reading it with the business model and volume in mind shows why a "low" net margin can still be excellent.

Failure modes to watch. Comparing net margins across unlike industries; mistaking a one-off tax or gain for operating strength; reading net margin without gross and operating margin; and assuming low net margin means a weak business.
