WhatsApp API pricing is conversation-based, not per-message. Understanding this model is essential before estimating your monthly costs. This guide explains every component with real Indian business examples.
The most important thing to understand: since July 2025, WhatsApp charges per message delivered, not per conversation window. Each template message sent is billed individually.
Example: You send a customer an order confirmation, shipping update, and delivery notification as three separate templates. That's 3 messages, 3 charges — unless they land inside an open service window, where utility templates are free.
Three windows stay free regardless: free-form replies inside the 24-hour window after a customer messages you, utility templates sent inside that same window, and any message sent inside a 72-hour window after a customer arrives via a click-to-WhatsApp ad. Marketing templates are always charged.
Change coming 1 October 2026: Meta announced on 1 July 2026 that the free 24-hour service window and free in-window utility templates end on that date and become billed per message at the standard rate for your market. Only the 72-hour click-to-WhatsApp entry window stays free after that. Meta is due to publish exact per-country rates by 1 September 2026.
Free-form replies cost nothing. When a customer messages your WhatsApp number first, you can reply freely for the next 24 hours with no template required and no charge. Customer support and inbound enquiries typically cost very little.
| Message type | Who initiates | India rate | Free window |
|---|---|---|---|
| Free-form reply | Customer messages first | Free | Inside 24hr service window |
| Utility | Business initiates (transactional) | ₹0.115 | Free inside service window |
| Authentication | Business initiates (OTP) | ₹0.115 | Free inside service window |
| Marketing | Business initiates (promotional) | ₹0.86 | Never free |
Rates may change: Meta adjusts WhatsApp message rates periodically. The rates above are current for India as of 2026. Always check the current rates in your Meta Business Manager → Billing for the most accurate figures. Also note: the "Free" and "Free inside service window" entries above apply as of mid-2026 only. Meta announced on 1 July 2026 that the free 24-hour service window and free in-window utility/authentication templates end on 1 October 2026, after which all three rows in this table are billed per message.
There's no ongoing monthly free-message tier under the current model. Instead, WA.Expert gives every new account a 3-day free trial with full platform access, no credit card required. Add your WhatsApp number and we credit ₹5 to your wallet automatically so you can test sending real messages at Meta's standard rates.
| Monthly messages | Meta fee | WA.Expert fee | Total monthly cost |
|---|---|---|---|
| 2,000 (1,000 utility, half free) | ~₹60 | ₹599 | ₹659 |
| 5,000 (3,000 utility + 1,000 mktg) | ~₹900 | ₹599 | ₹1,499 |
| 20,000 (15,000 utility + 5,000 mktg) | ~₹4,400 | ₹599 | ₹4,999 |
| 1,00,000 (80K utility + 20K mktg) | ~₹23,000 | ₹599 | ~₹23,600 |
ROI perspective: A D2C brand at 1,000 orders/month spending ₹3,000–5,000/month on WhatsApp API and BSP fees typically recovers ₹80,000–1,50,000/month in RTO reduction, cart recovery, and support savings. The ROI is typically 15–40× at this scale.
If a customer messaged you in the last 24 hours, a utility template sent to them right now is free. Time order updates and reminders to land while the window is still open where possible.
When a customer replies to your campaign, you're back inside a free service window for follow-ups. Route customer support, inbound leads, and replies through free-form messaging instead of templates.
Order updates, appointment reminders, payment receipts, if they're genuinely transactional, classify as Utility (₹0.115) not Marketing (₹0.86). The difference is 7× in cost per message, and Utility also qualifies for the free service window.
Sending marketing broadcasts to contacts who haven't bought in 12+ months and never engage wastes budget and degrades quality score. Regularly prune your broadcast list to active, high-intent customers.
Customers arriving via a Facebook or Instagram click-to-WhatsApp ad open a free 72-hour window, including templates — making ad-driven acquisition genuinely cheaper to message than cold outbound.
WA.Expert's trial gives you full platform access, no credit card required. Test sending real messages with ₹5 wallet credit added automatically.
