The 4 inputs that define your ROI
1) Current agent cost
How much does your team spend handling WhatsApp conversations today?
- Number of agents dedicated to WhatsApp
- Their average hourly cost (salary + overhead)
- Hours per day spent on WhatsApp
Example: 3 agents × $15/h × 8h = $360/day = ~$7,200/month in labor on WhatsApp alone.
2) Conversations handled (volume)
How many WhatsApp conversations does your business handle per month?
- Look at your WhatsApp Business app stats or meta dashboard
- Estimate if you don't track: (daily active customers × avg messages per customer)
3) Automated conversation rate
What % of those conversations can realistically be automated?
Industry benchmarks:
- eCommerce: 60–75% (order status, catalog, FAQs, returns)
- Healthcare: 50–65% (appointments, basic FAQs, reminders)
- Financial services: 40–55% (rates, basic account queries)
- Service businesses: 45–60% (quotes, scheduling)
Start conservative: use 50%.
4) Conversion rate lift
What % improvement do you expect on conversation-to-sale/booking conversion?
- Faster response → more conversions (benchmark: 3x faster response = +25–40% conversion)
- 24/7 availability → capture after-hours leads (benchmark: +30–40% lead capture)
- Better qualification → fewer non-buyer conversations → higher close rate
The formula
Monthly labor savings = (Automated conversation % × conversations/month) × (avg handle time × agent hourly cost)
Monthly revenue lift = (Monthly conversations × current conversion rate × conversion lift %) × average deal value
Monthly ROI = (Labor savings + Revenue lift − Tool cost) / Tool cost × 100
Example calculation
| Variable | Value |
|---|---|
| Conversations/month | 1,200 |
| Automated % | 55% |
| Avg handle time | 8 min |
| Agent hourly cost | $15 |
| Current conversion rate | 8% |
| Conversion lift | 30% |
| Avg deal value | $120 |
| Tool cost | $79/month |
Labor savings: 1,200 × 55% × (8/60) × $15 = $1,320/month
Revenue lift: 1,200 × 8% × 30% × $120 = $3,456/month
Total return: $4,776 ROI (example): ($4,776 − $79) / $79 = ~5,950% monthly
In this example, the payback period is under 1 week. Your own numbers may be different.

Is the ROI calculator accurate for my industry?
The calculator gives directional estimates. Actual results vary by team, volume, and use case. Use it to build the business case, then validate with a 30-day pilot.
What if I don't know my current conversion rate?
Start with a conservative estimate (5% for most eCommerce stores, 10–15% for services with direct inquiry). Track actual rates after deployment to refine.
Does automation replace all my agents?
No. The ROI comes from handling routine conversations automatically — freeing agents for complex, high-value conversations where humans are better. Most businesses reduce WhatsApp headcount needs by 40–60%, not 100%.
How long to see results?
Most businesses see ROI within the first 2–4 weeks: agents spend less time on repetitive queries within days of deployment.
