ROI stands for Return on Investment. It is expressed as a percentage and answers a simple question: Was my investment worth it? It can be calculated for a campaign, a channel, a tool, or any business initiative.

Why does it matter?

ROI allows you to compare different investments using the same standard. It helps you prioritize, justify your budget, and stop investing in what doesn't pay off.

Don't confuse it with ROAS, which measures sales relative to advertising spend. ROI takes profit into account—that is, it subtracts costs. And for it to be reliable, it's best to measure incremental profit, not all sales that occurred after the campaign.

How is it calculated?

Formula: ROI = (profit earned − investment) ÷ investment × 100.

For example: You invest $1,000 in a campaign and earn an incremental profit of $4,000. The ROI is ($4,000 − $1,000) ÷ $1,000 × 100 = 300%. For every peso you invested, you recouped that peso and earned three more.

Story mode

An online sports retailer invests in a WhatsApp campaign targeting at-risk customers. By comparing results with a control group, it finds that the campaign generated additional sales that would not have occurred without it. It calculates the profit from those sales, subtracts the cost of the campaign, and arrives at a positive ROI. It decides to repeat the campaign every quarter.
