Return on investment

(ROI)

A measure of how much return is received - or expected to be received - compared to the investment made.

ROI is usually expressed as a percentage.

Definitions of both return and investment may vary, depending on the use to which the measure is put.

For this reason - here as elsewhere - the basis of the calculation should be stated explicitly, for the avoidance of any doubt.
