What is ROI?
Return on Investment or ROI is a common metric used to measure the profitability of an investment.
Investors usually use this to calculate the gain generated from an investment. This helps them understand how well a campaign or a model performed.
It is done by using a specific formula:
ROI = (Net Profit / Cost of Investment) x 100
Let's suppose you have invested $1,000 in an ad campaign and generated $3,000 in sales.
Considering the formula: ROI = (($3,000 - $1,000) / $1,000) x 100 ROI = 200%
Here the ROI is 200%. It shows that for every dollar invested, there was a return of $2. This indicates that the campaign had a positive ROI.
