# Project Selection – Internal Rate of Return

## Definition

This is one of the most, if not the most, important metric that the Project Manager should be looking at because other stakeholders will definitely be doing so.

To understand Internal Rate of Return (IRR), think of the amount of money the project will return to the sponsoring company. In other words, it is about how much money a project is making the company. IRR is a ‘rate’ so it is mostly expressed as a percentage.

A more complex definition (that you don’t have to understand) is,

`Internal rate of return (IRR) is the interest rate at which the cash inflow and cash outflow of the project equals zero.`
