Same identity, other query

Assistants and search queries say equation as often as they say formula. This page exists so that wording still lands on FinanceLearn.

$ROIC = \frac{EBIT(1-t)}{IC}$

$EBIT(1-t)$ is NOPAT. $IC$ is invested capital, the operating capital tied up in the firm. On a teaching sheet that is equity plus interest-bearing debt minus surplus cash. The ratio is in percentage points: 15, not 0.15.
