Calculator FAQ
How does this calculator estimate WhatsApp API cost?
It applies per-message rates for your selected market across marketing, utility, authentication, and auth-international categories, then totals the cost monthly and annually.
Are free messages inside the 24-hour customer service window included?
Non-template messages are free and not billed here. Utility templates can also be modeled as free using the Utility inside CSW percentage input.
Why does Auth-International sometimes match Auth?
Meta does not publish Auth-Intl for every market. In those cases, this tool falls back to that market's Auth rate and shows that note explicitly.
