What is ROI?

ROI stands for “Return on Investment” and is a metric businesses and individuals use to work out how much revenue they can generate when considering the costs of generating that revenue.

For example, if you spend $1000 on a sales promotion that generates $3000, your ROI is 200%, or $2000.

ROI doesn’t just have to refer to profits. It can also refer to other measures, like time.
