The term ROI is the acronym of the English expression Return On Investment<\/em>, which is translated in Spanish as retorno de la inversi\u00f3n. ROI<\/a> is an economic KPI that lets us know the profitability obtained from a project, investment, marketing campaign, etc.<\/p>\n

Put more simply, ROI tells us how much has been generated for every euro invested in, for example, an email marketing campaign<\/a>. The relationship between the money invested and the money generated by that investment.<\/p>\n

1. How to calculate or measure ROI?<\/h2>\n

Calculating ROI is not difficult, you can use this simple formula:<\/p>\n

ROI = ((Ingresos - Gastos) \/ Gastos) x 100<\/code><\/p>\n

Let’s take an example, where we have made an Ads campaign worth 1,650 euros (total cost of time invested, cost of the campaign in Ads, payment to the graphic designer who creates the design and the copywriter who creates the texts), and thanks to it we have achieved sales of 9,500 euros.<\/p>\n

ROI = (9.500 - 1.650 \/ 1.650) x 100<\/code><\/p>\n

Therefore, for every euro spent, we have made 4.75 euros (4.75:1 ratio). And in percentage terms, a 475.75% return on investment.<\/p>\n

It is estimated that, in digital marketing campaigns, an acceptable ROI is between 4:1 and 6:1, i.e. for every euro invested, between 4 and 6 euros are earned. Achieving a ratio of 10:1 is considered a great result. If the result is lower than this data (less than 4:1), we can say that the digital marketing action has much room for improvement.<\/p>\n
