Short answer: From 1 October 2026, Meta charges Indian businesses:
- ₹0.8631 per delivered marketing message,
- ₹0.115 per utility or authentication message,
- ₹0.115 per service reply after the first 1,000 free each month per phone number,
plus 18% GST. Your WhatsApp platform or Business Solution Provider (BSP) adds its own monthly fee on top.
The two layers of WhatsApp API cost
Every WhatsApp Business API bill in India has two parts:
- Meta's message charges. Paid per delivered message, by category, billed in INR.
- Your platform's fee. What your BSP or software charges for the inbox, chatbot, campaigns and analytics. It's usually a monthly subscription, sometimes with a per-message markup.
Getting access to the API itself costs nothing from Meta. There's no licence fee or per-seat fee from Meta.
Meta's WhatsApp rates in India from 1 October 2026
| Message category | What it's for | Rate per delivered message (excl. GST) | Approx. incl. 18% GST |
|---|---|---|---|
| Marketing | Offers, promotions, broadcasts, re-engagement | ₹0.8631 | ≈ ₹1.02 |
| Utility | Order updates, booking confirmations, payment reminders | ₹0.115 | ≈ ₹0.136 |
| Authentication | OTPs and login codes | ₹0.115 | ≈ ₹0.136 |
| Service (replies inside the 24-hour window) | Answering customer messages, by a human or an AI | First 1,000/month per number free, then ₹0.115 | ≈ ₹0.136 after the free 1,000 |
Rates checked against Meta's October 2026 rate-card reporting. Meta updates rate cards periodically, so check the official WhatsApp Business Platform pricing page before budgeting.
What changed on 1 October 2026
Until 30 September 2026, replies sent inside the 24-hour customer service window were free, however many you sent. From 1 October:
- Service messages are charged. Each business phone number gets 1,000 free service messages per month. From message 1,001, each reply costs ₹0.115.
- Utility messages inside the window are charged too. Utility templates sent inside an open window, previously free, now cost ₹0.115 each.
- Marketing and authentication rates haven't changed.
- You need a payment method on file. Businesses without one risk having service messages interrupted.
Why this matters more than it looks: the rate is small, but the volume isn't. A booking conversation where your bot sends five replies uses five service messages. Two hundred bookings a month at five replies each is 1,000 messages—your whole free allowance—before you've answered a single general enquiry. Chatty bots now cost money.
Worked examples
Example 1: A small clinic
- 300 marketing messages (recall offers)
- 600 utility messages (appointment confirmations and reminders)
- 2,500 service replies (patient questions and booking chats)
| Item | Calculation | Cost |
|---|---|---|
| Marketing | 300 × ₹0.8631 | ₹258.93 |
| Utility | 600 × ₹0.115 | ₹69.00 |
| Service | (2,500 − 1,000 free) × ₹0.115 | ₹172.50 |
| Meta total (excl. GST) | ₹500.43 | |
| With 18% GST | ≈ ₹590.51 |
Example 2: A growing D2C brand
- 10,000 marketing messages (two campaigns)
- 5,000 utility messages (order and shipping updates)
- 8,000 service replies (customer support)
| Item | Calculation | Cost |
|---|---|---|
| Marketing | 10,000 × ₹0.8631 | ₹8,631.00 |
| Utility | 5,000 × ₹0.115 | ₹575.00 |
| Service | (8,000 − 1,000 free) × ₹0.115 | ₹805.00 |
| Meta total (excl. GST) | ₹10,011.00 | |
| With 18% GST | ≈ ₹11,812.98 |
Add your platform's subscription to both examples to get the full monthly bill.
What WhatsApp platforms charge: the second layer
Platform fees vary widely. Here is how several popular BSPs structure their pricing as of October 2026:
| Platform | Entry pricing | Notes |
|---|---|---|
| AiSensy | Basic from ₹1,500/month | AI Agent Builder is a separate ₹1,350/month add-on with 1,000 AI messages |
| Wati | Varies by plan and billing cycle | Astra AI agents and some usage are priced separately; check the current pricing page |
| Interakt, Gallabox, Gupshup and others | Varies by plan | Check each vendor's current pricing page |
| NimbleBiz | Bundles include monthly allowances for AI replies, voice minutes or WhatsApp broadcasts; extra usage is billed from your wallet | See the pricing page |
When comparing, check:
- whether Meta's charges are passed through at cost or marked up per message,
- how many agent seats are included,
- whether AI replies, chatbots and integrations are add-ons,
- whether you can see cost per lead and cost per sale, not just messages sent.
Five ways to keep your WhatsApp bill down after 1 October
- Cut reply count, not replies. Ask for date, time and name in one message instead of three. Fewer, smarter replies keep you inside the 1,000 free service messages.
- Use Click-to-WhatsApp ads deliberately. Meta's documentation describes a free entry-point window after you reply to someone who came from a Click-to-WhatsApp ad. Check current terms, then plan your follow-ups inside it.
- Send marketing only to people likely to act. At ₹0.8631 each, a 20,000-contact blast is ₹17,262 before GST. Segment by lead score and recent engagement instead of blasting everyone.
- Use utility templates for genuine updates. Confirmations and reminders cost far less than marketing messages, but only use them for real transactional updates, or Meta may recategorise them.
- Track cost per lead, not cost per message. The question isn't "how much did WhatsApp cost?" It's "how much did each booked customer cost?"
Is bulk WhatsApp messaging legal in India?
Yes, when you send through the official WhatsApp Business API using approved templates to contacts who have opted in, and you honour opt-outs. What gets businesses into trouble:
- Unofficial "bulk sender" tools, browser extensions or modified apps. They break WhatsApp's terms and can get numbers permanently banned.
- Bought or scraped number lists. There's no consent behind them.
- Ignoring opt-outs. It invites blocks and reports, and Meta can restrict your number quickly.
India's Digital Personal Data Protection Act, 2023 requires consent to be free, specific, informed, unconditional and unambiguous when consent is the basis for processing personal data such as phone numbers. Keep a record of how and when each contact opted in, and make withdrawal easy.
How NimbleBiz helps you see what WhatsApp actually costs per customer
- Attribution to the ad. Every WhatsApp conversation is traced back to the Meta campaign, ad set and ad that started it, so you see real CPL and CPS (cost per lead and cost per sale).
- Bulk campaigns with live tracking. Delivery, failure, reply and lead tracking on every send, through the official Meta Business API.
- NBScore segmentation. Send marketing to leads most likely to convert instead of the whole list.
- Fewer, smarter AI replies. The AI captures several details per message, which keeps you inside the free service allowance for longer.
You'll know exactly what each WhatsApp lead costs, and which campaigns earn their spend.
Frequently asked questions
How much does WhatsApp Business API cost in India in 2026?
From 1 October 2026, Meta charges ₹0.8631 per marketing message and ₹0.115 per utility or authentication message. Service replies inside the 24-hour window are free for the first 1,000 per phone number each month, then ₹0.115 each. Add 18% GST and your platform's subscription fee.
Are WhatsApp customer service replies still free?
Only the first 1,000 service messages per phone number per month. From 1 October 2026, each service message after that costs ₹0.115, excluding GST. Before October, all replies inside the 24-hour window were free.
Is there a monthly fee for WhatsApp Business API?
Meta doesn't charge a monthly or licence fee for API access; you pay per delivered message. Your platform or BSP usually charges a monthly subscription for the inbox, automation and analytics.
Is GST charged on WhatsApp Business API messages in India?
Yes. 18% GST applies on top of Meta's per-message charges, so a ₹0.8631 marketing message costs about ₹1.02 including GST.
Is bulk WhatsApp messaging legal in India?
Yes, through the official WhatsApp Business API, with approved templates, to contacts who opted in, and with opt-outs honoured. Unofficial bulk-sender tools and bought number lists break WhatsApp's terms, risk a permanent ban, and may breach India's DPDP Act consent requirements.
How can I reduce my WhatsApp API cost?
Send fewer, smarter service replies so you stay inside the 1,000 free messages, segment marketing to high-intent contacts instead of blasting everyone, use utility templates only for genuine updates, and measure cost per lead and per sale rather than cost per message.
