Each message type has a different winner
India auth costs about ₹0.09 on WhatsApp's entry tier against ₹0.12–0.35 for SMS — cheaper and far better delivered into the right app.
Order updates at ~₹0.12 versus SMS at ₹0.25+ — and the WhatsApp copy with a button gets the reply, not the spam folder.
WhatsApp marketing (~₹0.89) costs more than SMS (~₹0.30) and email (~₹0.05). Use WhatsApp for opted-in, high-value offers; email for volume; SMS for reach.

WhatsApp vs SMS cost questions
Is WhatsApp really cheaper than SMS in India?
For most volumes, yes on the Meta platform fee: an authentication message costs about ₹0.09 on WhatsApp's entry tier versus roughly ₹0.12–0.35 for a transactional SMS, and utility messages are a fraction of SMS prices too. Marketing messages cost more on WhatsApp than SMS — so the honest answer depends on your mix, which is exactly what this calculator shows per message type.
What costs are compared here?
WhatsApp: Meta's entry-tier platform fee per delivered template message for India (marketing, utility, authentication), converted to rupees. SMS: your per-message bulk SMS rate, editable (typical transactional rates run ₹0.12–0.35). Email: your per-email rate, editable (bulk providers run a few paise per email). Platform or gateway markups are separate and not included.
Why is the comparison not apples-to-apples?
Cost per delivered message is only half the story. WhatsApp messages open at roughly a 98% rate versus about 20% for email, and they require opt-in customers and Meta-approved templates. SMS reaches any phone without an app but is billed per segment both ways. Email is cheapest but weakest for time-sensitive messages. Use the calculator for the bill, and judge engagement separately.
Can I really send WhatsApp at Meta's rates?
Yes — the WhatsApp Business API bills the Meta platform fee to you directly. Providers add their own markup on top; The Tech Pad connects numbers through Meta's official Cloud API and passes Meta fees through at cost, so the WhatsApp columns here match what Tech Pad customers pay at the platform level.
Where do the WhatsApp rates come from?
India entry-tier per-message fees on Meta's card as compiled on 8 September 2026 — about $0.0107 marketing, $0.0014 utility and $0.0011 authentication. Every rate is editable, and Meta changes its card periodically, so confirm the current numbers on Meta's official pricing documentation.
