Net income formula

The net income realized before deducting taxes is called NIBT (Net income before taxes). Inversely, the profit left over after paying tax on this amount is called NIAT (Net income after taxes).

Net income is used as a metric to measure the profitability of a company within a specific period. It is also important for calculating earnings per share (EPS). It is shown in the income statement of the company under profits at the bottom part of the income statement.
