What India businesses actually pay in 2026

Meta moved to fully per-conversation billing on the WhatsApp Business Platform in mid-2025, and the India rate card is one of the most aggressive globally. Marketing conversations sit around ₹0.78 each; utility and authentication conversations have been consolidated into a low ₹0.115 band; and service conversations (where the user messages you first) are free for the duration of the 24-hour window.

The most common misunderstanding for Indian buyers is the difference between Meta's wholesale conversation rate and the markup that BSPs (Business Solution Providers like Wati, Interakt, AiSensy, Gupshup) charge on top. BSP markups range from a flat platform fee with at-cost messaging through to a 30–60% markup on Meta's per-conversation rate. The calculator above shows the Meta wholesale number — your invoiced amount will be that plus your BSP's margin.

Regulatory note (DPDP): India's Digital Personal Data Protection Act, 2023 is in force in 2026. If you store or process WhatsApp message data, you are a Data Fiduciary under DPDP. Practical implications: maintain a notice + consent record for every opted-in number, honour erasure requests inside 30 days, and sign a data-processing agreement with your BSP. None of this changes Meta's pricing — but it does change which BSPs are safe to use.

Authentication conversations (the OTP/login use case) are the biggest unlock for Indian fintech and e-commerce: at ₹0.115 per conversation, WhatsApp OTP is now decisively cheaper than SMS DLT traffic, even before you count higher delivery rates and the read receipt.

Frequently asked questions

How much does WhatsApp Business API cost per message in India in 2026?

Meta does not bill per message — it bills per 24-hour conversation. India rates in 2026 are approximately ₹0.78 for marketing conversations, ₹0.115 for utility, ₹0.115 for authentication, and ₹0 for service conversations. Inside a single 24-hour conversation window you can send unlimited messages at no extra Meta cost.

Are the first 1,000 conversations per month still free in India?

No. Meta retired the universal 1,000 free conversations / month allowance for marketing, utility, and authentication conversations in mid-2025. Service (user-initiated) conversations remain free. Some BSPs may bundle a small free tier for testing.

Do I have to pay GST on WhatsApp Business API in India?

Yes. WhatsApp Business API charges from Meta and your BSP are subject to 18% GST in India. Most BSPs invoice in INR with GST applied; if Meta bills you directly in USD, you self-account for GST under reverse charge.

What is the difference between Meta's rate and what Wati / Interakt / AiSensy charge?

Meta's per-conversation rate is wholesale. Indian BSPs add either (a) a fixed monthly platform fee with conversations billed at-cost, or (b) a marked-up per-conversation rate (typically 25–60% above Meta's number) and no platform fee. The calculator above shows Meta wholesale — add your BSP's structure on top.

Is WhatsApp Business API DPDP-compliant in India?

WhatsApp itself is end-to-end encrypted and Meta is a processor for your messages. To stay DPDP-compliant you need: explicit opt-in records for every number, a published privacy notice, a documented retention period, an erasure workflow, and a signed DPA with your BSP. Several Indian BSPs publish DPDP addendums on request.

Why are authentication conversations cheaper than marketing in India?

Meta deliberately priced authentication conversations to undercut DLT-routed SMS in the OTP market — a high-volume use case where SMS still dominates. At ₹0.115 per authentication conversation, WhatsApp is competitive with SMS DLT pricing while delivering higher open and read rates.
