How the rates work
Meta charges per conversation — a 24-hour window between your business and one customer phone number — not per message. Rates are set per country and per category. India rates as of 2026:
| Category | India rate (INR) | Typical use |
|---|---|---|
| Marketing | ₹0.78 | Broadcasts, promotions, abandoned cart |
| Utility | ₹0.114 | Order updates, payment receipts, reminders |
| Authentication | ₹0.114 | OTPs, login codes |
| Service | Free | Replies inside the 24h customer-reply window |
Rates shown are Meta's wholesale conversation rates for India. BSPs may add a markup on top. The WatEase Free Forever plan passes Meta rates through at cost; the Professional plan (₹999/month) bundles unlimited platform usage on top of Meta's pass-through rates.
How to use the calculator
- Estimate the number of Marketing conversations you send per month — broadcasts, promotional flows, abandoned cart.
- Estimate Utility — transactional messages tied to an existing relationship.
- Estimate Authentication — OTPs and login codes.
- Service replies are free; the field is optional and does not affect the total.
- The calculator multiplies each by the India rate and sums to a monthly total in INR.
Tips to lower your bill
- Route every transactional alert as Utility, never Marketing — order confirmations, payment receipts, shipping updates all qualify.
- Design support flows so replies happen inside the free 24-hour Service window after a customer message.
- Segment broadcasts so you don't blast the entire list — that protects quality rating and avoids tier downgrades that compress messaging volume.
- For OTPs above 100,000/month, consider Meta's Authentication International rates which can be cheaper for some international destinations.
