This is an estimate for planning only. Since 1 July 2025 WhatsApp bills per delivered message, by template category. Your actual per-message rates vary by category and destination country and are always shown in your InfiQ in-dashboard rate card before you send. Since 1 October 2026, utility messages sent inside the open 24-hour customer-service window are charged too, and service messages are priced per market (both were free until 30 September 2026) — this estimate uses the India rate of ₹0.145 per service message.

The pricing model
How WhatsApp Business API pricing actually works
A WhatsApp Business API bill has two parts. The first is the platform subscription — what you pay your provider for the software: the shared team inbox, broadcast campaigns, CRM and analytics, with the chatbot and developer API on higher tiers. On InfiQ that is ₹999/month on Lite or ₹2,999/month on Growth (which adds API, webhooks and a chatbot), with plan details on the pricing page. The second part is messaging: your provider's per-message charge for each template message you send, priced by category.
Messaging charges are category-based. Marketing templates — promotions, offers, win-back campaigns — carry the highest rate. Utility templates for order confirmations and delivery updates, and authentication templates for one-time passcodes, are priced much lower — and since 1 October 2026 utility messages are charged inside the open 24-hour service window too. Since 1 July 2025 billing is per delivered message. Rates vary by category and the customer's country and are revised periodically, which is why this calculator lets you edit every rate instead of hard-coding numbers that would drift out of date. The defaults are indicative only — check your provider's rate card, or on InfiQ, the live rate card in your dashboard. And when a customer messages you first, a 24-hour service window opens for free-form service replies, which need no template but have cost ₹0.145 each in India since 1 October 2026 (they were ₹0 until 30 September 2026) — so support-heavy businesses, long the cheapest profile to run, should model their in-window volume too.
A few budgeting habits keep estimates honest. Build your projection from real numbers — last quarter's order volume for utility messages, your active login base for authentication, planned campaign reach for marketing — rather than a single blended figure. Model a realistic range, not one scenario: a festive-season month can carry several times the marketing volume of a quiet one. And revisit the numbers quarterly, because both your mix and the underlying rates shift over time.
Marketing pricing has one new variable in beta. Meta's max price is a ceiling on what Meta charges for each delivered marketing message sent through its Marketing Messages API. It caps the charge per delivery, not a campaign's total. It is available in beta through InfiQ, but InfiQ billing for max-price messages is to be announced, so this calculator keeps a single per-message rate for marketing sent without a max price. How max price works.
When you want to go deeper, two companion tools pick up where this one stops. The conversation cost estimator breaks down what a single message costs by template category and destination country, while the broadcast cost calculator prices an individual campaign against its expected returns. Used together, they turn a rough monthly guess into a budget you can defend.
FAQ
Frequently asked questions
Are the default rates in this calculator Meta's official prices?
No. The pre-filled rates are InfiQ's indicative India rates (ex-GST) so the calculator produces a number out of the box — edit them to match your own rate card. Since 1 July 2025 WhatsApp bills per delivered message, and actual per-message rates vary by template category, depend on your provider and the destination country, and are revised periodically. On InfiQ, your exact live rates are always visible in the in-dashboard rate card before you send.
What are marketing, utility, authentication and service messages?
WhatsApp bills business-initiated messages by template category. Marketing covers promotions, offers and win-back campaigns; utility covers transactional updates like order confirmations and delivery alerts; authentication covers one-time passcodes. Marketing is always charged and typically the most expensive category, while utility and authentication are priced significantly lower. Service messages are the free-form replies you send inside an open 24-hour customer window — they need no template, and they have been charged per message since 1 October 2026. Since the same date, utility messages are charged inside the open 24-hour service window too (they were free there until 30 September 2026).
Do replies inside the 24-hour window cost extra?
Yes, since 1 October 2026. When a customer messages you, a 24-hour customer-service window opens; the customer's own messages are never billed, but the free-form service replies you send inside that window are charged per message (₹0.145 each in India), and so are utility messages sent inside it. Both were free until 30 September 2026. Support-heavy messaging still costs far less than outbound campaigns at the same volume, so model your in-window volume alongside your campaigns.
Does the estimate include GST?
Yes. The calculator adds 18% GST on top of the platform and messaging subtotal, matching how invoices are raised for businesses in India. The subtotal and GST amount are shown separately so you can compare the numbers against your own projections.
How can I reduce my WhatsApp messaging bill?
Three levers matter most: use utility templates for transactional updates instead of marketing templates, segment your audience so campaigns only reach contacts likely to respond, and answer inbound chats within the 24-hour window, where replies need no template and cost far less than a marketing send. Good segmentation often cuts campaign spend more than any rate negotiation.
