Meta moved template-message billing from per-conversation to per-message on 1 July 2025; the rates above are Meta's published per-message wholesale rates for India as of 2026-05. Rates may change; check Meta's pricing page for latest. Excludes BSP platform fees. WatEase passes Meta wholesale rates through at cost on the Free Forever plan.
How the rates work
Since 1 July 2025 Meta charges template messages (Marketing, Utility, Authentication) per message, not per conversation window. Service conversations — your replies within 24 hours of a customer message — remain free in India. Per-message India rates as of 2026 (template messages):
| 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.

What changed with WhatsApp conversation-based pricing?
Meta moved template-message billing from per-conversation (a 24-hour window) to per-message on 1 July 2025. Under the old model, any number of messages to one customer in 24 hours counted as a single charge. Under the current model, each Marketing, Utility, or Authentication template message sent is billed individually. Service conversations — replies within 24 hours after a customer messages you first — remain free regardless of how many messages are exchanged.
Are WhatsApp service replies free in India?
Yes. Service conversations — your replies inside the 24-hour window after a customer messages you first — are billed at ₹0 in India. Only business-initiated Marketing, Utility, and Authentication conversations carry a charge.
How can I lower my WhatsApp Business API bill?
Route every transactional alert (order confirmations, payment receipts, shipping updates) as Utility, not Marketing — Utility is far cheaper. Design support flows so replies land inside the free 24-hour Service window. Segment broadcasts instead of blasting the whole list, which also protects your quality rating and avoids tier downgrades.
