Return on invested capital

Also called ROIC

Operating profit after tax as a percentage of all the capital invested in the business, debt and equity alike.

How it works

ROIC is the cleanest measure of business quality because it is not distorted by financing structure. It asks what return the operations earn on every pound put into them.

The number that matters is ROIC compared with the cost of that capital. A company earning above its WACC creates value as it grows; one earning below it destroys value the faster it grows.

Formula

ROIC = net operating profit after tax ÷ (total debt + equity − cash)

Worked example

A company earning 18% ROIC against a 9% WACC is creating roughly 9 points of value on every unit of capital it deploys.
