You must subtract the initial money invested from your current revenue to get your net return. Then you divide by your initial digital marketing spend before multiplying by 100.

So, if you invest $4 and make a revenue of $20, your net return is $16.

Then, you divide $16 by your initial marketing spend, which was $4. This gives a total of 4, which you will multiply by 100 to give you 400 – meaning your ROI is 400% (4:1).

In digital marketing, an ROI of 5:1 is a success, but most marketers usually aim for higher. Also, remember that each marketing channel has a different ROI ratio that you can use as a scale –email marketing (36:1), PPC (2:1), and SEO (22:1).
