Estimates from each platform's public pricing, checked 29 October 2026, with 18% GST included. GST is added to plan fees, to Meta's charges and to the other platforms' per-message rates, which are listed before GST (AiSensy's page and WATI's rate card do not say, so their rates are treated as before GST). PayPerWA's ₹0.20 fee already includes GST, so GST is added only to Meta's part of PayPerWA messages. Prices checked on 2026-10-18 for PayPerWA's fee. Plan fees are the cheapest plan that can send WhatsApp broadcasts, on the shortest billing cycle sold, shown per month (Interakt Starter and DoubleTick Starter are billed quarterly). Meta's per-message charges are identical across providers — the difference is the subscription plus each platform's per-message margin. AiSensy, Interakt and DoubleTick rates are their published India rates; WATI's come from the Growth-plan rate card linked from its pricing page (Pro and Business get an unstated discount). WATI Growth caps broadcasts at 15,000 a month, so above 15,000 marketing messages the WATI row uses Pro (₹6,499 a month) at those rates, an upper bound. PayPerWA's ₹0.20 fee is counted on every message, every service reply included. Messages inside a free entry point window (a chat from a Click to WhatsApp ad, open for up to 7 days) carry no Meta charge and are not deducted here.
Understanding the Real Cost of WhatsApp Marketing
Marketing · ₹0.86
Promotions, offers, sale announcements, abandoned-cart recovery, re-engagement broadcasts. Meta charges ₹0.86 per message regardless of which platform you use.
Utility · ₹0.115
Order confirmations, delivery updates, appointment reminders, payment receipts, account alerts. About seven and a half times cheaper than marketing — use this category wherever possible.
Authentication · ₹0.115
OTPs, 2FA codes, login verification. Cheaper than SMS OTP (typically ₹0.18–₹0.30) and has 98%+ delivery rate thanks to Meta's infrastructure.
Pro tip: conversations that start from a Click to WhatsApp ad, and get your reply within 24 hours, open a free entry point window that can stay open for up to 7 days. Marketing, utility, authentication and service messages inside it are FREE of Meta charges; PayPerWA's ₹0.20 fee, GST included, still applies to each one. Ordinary replies inside the 24-hour service window are charged by Meta since 1 October 2026, at its utility rate, once a business number has used its 1,000 free service messages for the month.

Pricing Questions Answered
WhatsApp Business API pricing has two parts: (1) Meta's per-message charges, which are identical across providers — about ₹0.86 per marketing message, ₹0.115 per utility message and ₹0.115 per authentication message; since 1 October 2026 Meta also charges ₹0.115 for each service reply, after the first 1,000 free service messages each business number gets per month. (2) Platform fees which each provider sets — this is where prices vary. PayPerWA charges a flat ₹0.20 per message, GST included, on top of Meta's charges, with zero monthly subscription, while the other four platforms in this calculator charge about ₹1,170 to ₹3,500 a month for their entry plans (before GST, checked 29 October 2026) plus their own per-message margins. Meta's charges and those plans attract 18% GST; the calculator adds it.
Meta categorises every template message: Marketing messages are promotional — broadcasts, offers, and campaigns. Utility messages are transactional — order confirmations, delivery updates, appointment reminders. Authentication messages are OTPs and login codes. Marketing is the most expensive at ₹0.86, while utility and authentication are ₹0.115 each. Choosing the right category for each template saves you a lot of money.
Mostly the subscription. AiSensy, Interakt, WATI and DoubleTick charge about ₹1,170 to ₹3,500 a month for their entry plans before GST (checked 29 October 2026), whatever you send. PayPerWA charges ₹0 a month. Per message the gap is smaller and runs the other way: PayPerWA adds ₹0.20, GST included, to Meta's charge on every message, while the India rates AiSensy, Interakt, WATI and DoubleTick publish add about ₹0.11 to ₹0.23 to a marketing message and ₹0.01 to ₹0.05 to a utility message before GST (about ₹0.13 to ₹0.27 and ₹0.01 to ₹0.06 with it). The calculator compares everything with 18% GST included, adding it to Meta's charges, the plans and the other platforms' rates but not to PayPerWA's fee, which already includes it. So PayPerWA tends to cost less when volumes are low or seasonal, and a subscription plan can cost less once you send enough messages each month. Move the sliders to see which is cheaper for your volume.
They were read from each provider's public pricing on 17 October 2026 and re-checked on 29 October 2026: the cheapest plan that can send WhatsApp broadcasts, on the shortest billing cycle it sells, before GST, plus its published India per-message rates. The calculator then adds 18% GST to them. PayPerWA's ₹0.20 fee was checked on 18 October 2026 and already includes GST. WATI's India rates come from the Growth-plan rate card linked from its pricing page (dated 1 October 2026); its Pro and Business plans get an unstated discount on them. Prices change, and some providers offer custom enterprise pricing that may be lower at very high volumes. Meta's per-message charges (₹0.8631, ₹0.115, ₹0.115) are identical across every provider because Meta bills them directly.
Since 1 October 2026, only up to a monthly allowance. When a customer messages your business, a 24-hour customer service window opens. Until 30 September 2026 Meta did not charge for service replies (free-form, non-template messages) or for utility templates delivered inside that window. From 1 October 2026 Meta charges utility templates there at the utility rate. Service replies are free for the first 1,000 delivered from each business number in a month (the allowance resets monthly and does not roll over); after that they cost the same as a utility message in that market. What stays free is the free entry point window, which opens when a customer messages you from a Click to WhatsApp ad and you reply within 24 hours: it can stay open for up to 7 days, and Meta does not charge for marketing, utility, authentication or service messages inside it. PayPerWA, like every official Cloud API provider, passes Meta's charges through, and its own ₹0.20 fee (GST included) applies to every message, inside that window and to every service reply too.
With PayPerWA, no. Zero setup fee, zero monthly subscription and zero charge for failed messages (auto-refund). You pay ₹0.20 per message, GST included, on every message you send, replies included, on top of Meta's own per-message charge, and remember that since 1 October 2026 Meta also charges for service replies beyond the 1,000 free each business number gets per month. With subscription platforms, watch out for: user seat fees, team member charges, integration add-ons, chatbot flow limits, and SMS fallback charges.
