What It Measures
Net margin is a metric that shows what proportion of revenue is accounted for by the final profit figure (net income), which includes taxes and extraordinary gains and losses. It expresses how much profit ultimately accrues to shareholders across a company's overall activities.
How to Interpret It, and Points of Caution
Because net income is prone to being affected by extraordinary gains and losses, such as gains or losses on the sale of fixed assets or losses from disasters, net margin can fluctuate significantly from year to year. It is common to check it together with operating margin and ordinary income margin, and to assess whether any fluctuation reflects a one-off factor or a structural change.
