Qué es ROI (Return on Investment)?
Definición Rápida
El ROI (Retorno sobre la Inversión) mide la rentabilidad de una inversión, calculando el beneficio o pérdida generado en relación con el coste de la inversión.
Return on Investment (ROI) is the most fundamental business metric for evaluating whether an investment is worthwhile. The formula is: ROI = ((Revenue from Investment - Cost of Investment) / Cost of Investment) x 100. If you invest $10,000 in a marketing campaign and generate $30,000 in revenue, your ROI is 200%.
In digital marketing, ROI can be calculated for individual campaigns, channels, or your overall marketing spend. Google Ads ROI, email marketing ROI, social media ROI, and website ROI are all important to track independently to understand where your money works hardest.
ROI calculation becomes more nuanced when you consider customer lifetime value (CLV). A campaign that acquires a customer at a $100 loss on their first purchase might have excellent ROI if that customer spends $5,000 over their lifetime. This is why subscription and SaaS businesses can justify high acquisition costs.
Measuring digital marketing ROI requires proper tracking infrastructure. This means correctly configured analytics (Google Analytics, conversion tracking), attribution modeling (understanding which touchpoints contributed to a conversion), and accurate revenue reporting. Without this foundation, ROI calculations are unreliable.
Por Qué es Importante
ROI is the ultimate answer to the question every business owner asks: "Is this worth the money?" Without measuring ROI, you might be pouring money into channels that aren't working while under-investing in channels that could drive significant growth.
ROI measurement also enables data-driven budget allocation. When you know that email marketing delivers a 42:1 ROI while social media delivers a 10:1 ROI, you can make informed decisions about where to invest your next dollar.
Ejemplos Reales

An e-commerce company calculated that their email marketing generated $42 for every $1 spent (4,200% ROI), making it their most profitable channel by far
A restaurant calculated that their $2,000/month Google Ads campaign generated $12,000 in attributable reservations, a 500% ROI
A SaaS startup initially showed negative ROI on paid acquisition, but when accounting for 24-month customer lifetime value, the true ROI was 300%
