WhatsApp ROI calculator

How to calculate the real ROI of your WhatsApp channel

ROI (Return on Investment) is the return on what you invested. Simple formula: ROI = (Receita atribuída − Custo total) ÷ Custo total × 100. For the WhatsApp channel, these three components are:

• Assigned revenue — closed sales that had at least one interaction on WhatsApp. Use tags per campaign in CRM to measure accurately.
• Total cost — advertisements (Click-to-WhatsApp), tool licenses (extension, BSP), service team hours, possible commissions.
• Period — calculate month by month, then quarter, then year. Trend matters more than absolute numbers.

To understand the complete reasoning behind these three components — and a step-by-step numerical example — see WhatsApp ROI for sales: how to calculate the real return.

ROI benchmarks on WhatsApp in Brazil

Scenario	Typical ROI
E-commerce with cart recovery	8x-15x
Services with qualifying bot + Click-to-WhatsApp	5x-10x
Pure service without active capture	2x-4x
sending bulk messages without segmentation	Negative (ban cost)

Why Many Calculate ROI Wrong

• Do not attribute revenue to the channel — sales on WhatsApp are credited to "direct sales" because there is no tag/UTM.
• Forget operational costs — team hours are worth money.
• Only use most recent month — revenue may be inflated due to seasonality.
• Compare with channels with a different model — ROI from WhatsApp does not compare directly with ROAS from Meta Ads.
