The three components of WhatsApp ROI
WhatsApp Business API ROI consists of three elements: operational support cost savings (deflection), incremental revenue generated (conversions from campaigns, upsell), and loyalty value (churn reduction from better communications). Most companies measure only the first, missing a significant portion of total value.
To calculate support deflection savings, multiply the number of tickets avoided thanks to proactive WhatsApp notifications by the average ticket cost. If you avoid 500 tickets per month and each ticket costs 8 euros to handle, the monthly saving is 4,000 euros.
Key KPIs to monitor
Fundamental KPIs for measuring WhatsApp Business API effectiveness: delivery rate, read rate, response rate, conversion rate, and cost per conversation.
For marketing WhatsApp campaigns, track click rates on links in messages, conversions attributed via UTM and revenue generated per campaign. These data allow calculating the ROAS specific to the WhatsApp channel.
Industry benchmarks
Typical benchmarks for WhatsApp Business API: delivery rate 97-99%, read rate 85-95%, response rate 15-35% for Utility templates, 5-15% for Marketing templates. If your metrics are significantly lower, review the quality and relevance of your templates.
How to build a monthly ROI report
A monthly ROI report for WhatsApp must include: total channel cost (Meta conversation cost + BSP fee), number of messages sent and received by category, estimated tickets avoided, attributed conversions, revenue generated, and ROI calculated as (Revenue + Savings - Costs) / Costs.
