WhatsApp Conversation Charges Explained: 2026 Rates, Categories, Windows
WhatsApp moved from per-conversation to per-message billing in India. Here are the 2026 rates for every category, the 24-hour window rules, and four cases where messages are free.
WhatsApp conversation charges were rewritten from the ground up when Meta retired per-conversation billing and moved to per-message pricing for template messages. If you last modelled WhatsApp per message pricing in 2024, your spreadsheet is out of date. This guide explains the 2026 rate card for India, how the 24-hour customer service window decides what costs nothing, the shift to delivered-only billing, and every case where your messages are free.
What Changed: From Per-Conversation to Per-Message
Under the old model, Meta opened a "conversation" for each user and charged a flat fee for a 24-hour session, regardless of message count. Now Meta bills per delivered template message. The consequences are worth internalising:
- Every template message is its own line item — no free extra sends inside a paid conversation.
- Category determines price — marketing, utility and authentication each carry their own rate.
- Free-form conversation stays free — the 24-hour window still waives charges for genuine service dialogue.
- INR billing for Indian accounts since January 2026 — no more mental currency conversion.
The 2026 WhatsApp Rate Card for India
| Category | Rate per delivered message | What it covers |
|---|---|---|
| Marketing | ₹1.09 | Promotions, offers, newsletters, re-engagement |
| Utility | ₹0.145 | Order confirmations, shipping updates, OTPs, receipts |
| Authentication | ₹0.145 | Login codes and verification PINs |
| Service (free-form replies) | Free | Any reply inside an open 24-hour window |
On Whaterakt, the prepaid wallet bills these at Meta cost + 20% — ₹1.308 for marketing, ₹0.174 for utility and authentication — with no per-conversation charges on top. Full details are in our guide to WhatsApp API pricing in India.
The Three Template Categories and Their Use Cases
Marketing — ₹1.09 per delivered message
Any message whose primary purpose is promotion or engagement: festive sales, abandoned cart nudges, launches, re-engagement. The most expensive category, because Meta prices commercial reach at a premium — expect it to dominate your bill if you campaign frequently.
Utility — ₹0.145 per delivered message
Messages tied to a transaction the customer already initiated: order confirmed, out for delivery, appointment reminder, payment received. At roughly one-seventh of the marketing rate, classifying every eligible message correctly compounds into serious monthly savings.
Authentication — ₹0.145 per delivered message
One-time passwords and verification codes. Most Indian businesses send these from OTP infrastructure; through the Cloud API they cost ₹0.145 per delivered message.
The 24-Hour Customer Service Window
The window is the hinge of the whole pricing system. When a customer messages you first, a 24-hour customer service window opens. Inside it, free-form messages are completely free; when it closes, you can only re-open contact with an approved template, billed by category. Practical implications:
- Speed pays twice — a fast reply converts better and is free; a reply 25 hours later needs a paid template.
- Route conversations, not tickets — Whaterakt's shared team inbox keeps windows alive across agents, so anyone can jump in while it is still free.
- Design flows around windows — the no-code flow builder supports multi-day delays and stop-on-reply, so follow-ups land as free in-window replies when customers respond.
When WhatsApp Messages Are Free
- Service replies: free-form replies inside an open 24-hour window have been free since November 2024 — no conversation fee at all.
- Utility templates inside an open window: free; you only pay for utility templates sent cold, outside a window.
- Click-to-WhatsApp ad conversations: marketing templates delivered within 72 hours of a user tapping your Facebook or Instagram ad are free — you already paid for the click.
- Undelivered messages: Meta bills per delivered message, so anything that fails delivery is not charged.
Delivered-Only Billing, With Numbers
Meta bills only when a message is delivered, not when you hit send. Suppose you broadcast to 10,000 contacts with a 92% delivery rate:
| Scenario | Calculation | Cost |
|---|---|---|
| Billed on sends (old assumption) | 10,000 × ₹1.09 | ₹10,900.00 |
| Actual delivered-only billing | 9,200 × ₹1.09 | ₹10,028.00 |
| Saved by delivered-only billing | 800 × ₹1.09 | ₹872.00 |
The same broadcast at utility rates would cost 9,200 × ₹0.145 = ₹1,334.00 — a ₹8,694 difference from category choice alone. The full category and window rules live here.
INR Billing Localisation Since January 2026
Since January 2026 Meta bills Indian business accounts directly in INR at the published rupee rates. Budgeting is now arithmetic, not estimation: multiply delivered volume by the category rate. Whaterakt's wallet mirrors this — top up in rupees, every deduction is Meta cost + 20%, and the ledger shows exactly which template consumed what.
Frequently Asked Questions
Does WhatsApp still charge per conversation in 2026?
No. Meta replaced per-conversation billing with per-message billing for template messages. You pay per delivered template message at your category's rate, while free-form service replies inside the 24-hour window cost nothing.
What is the 24-hour rule in simple terms?
When a customer messages you, you have 24 hours to reply with free-form messages for free. After that, you must use approved templates and pay the per-message rate for the template's category.
Are utility templates always ₹0.145?
They cost ₹0.145 per delivered message when sent outside an open customer service window. Utility templates delivered inside an open 24-hour window are free.
Is authentication ever free?
No. Authentication templates are billed at ₹0.145 per delivered message regardless of window status. Only service replies, in-window utility templates, and marketing templates within 72 hours of a click-to-WhatsApp ad are free.
