WhatsApp Business API cost calculator

How the bill is built

Since 1 July 2025 Meta charges the WhatsApp Business Platform per delivered message. The price depends on two things: the category of the message and the country code of the recipient.

• Marketing templates are the expensive ones and are always charged.
• Utility templates (order and booking updates) and authentication templates (passcodes) share a much lower rate.
• Replies inside the 24-hour window after a customer writes are "service messages".

The rates in the calculator are Meta's list rates in US dollars for a handful of markets, read from Meta's own rate calculator. The full table per market is in the API guide.

What changes on 1 October 2026

Until that date every reply inside the 24-hour window is free, however many you send. From 1 October 2026, each business phone number gets 1,000 free service messages a month, and replies beyond that cost the utility rate of the customer's market. Utility templates sent inside an open window, free until then, are charged from the same day.

For a small shop that answers a few hundred chats a month nothing changes. For a busy support team or a chatbot, which can send ten replies in one conversation, it is a new line on the bill, and one that older pricing guides and several vendor pages do not mention yet. Switch the pricing rule in the calculator to see the difference for your own numbers.

What the estimate does not include

• Your platform's subscription, and any per-conversation or per-contact charges it has.
• The free entry point: when a customer reaches you from the WhatsApp phone app through a click-to-WhatsApp ad or a Facebook Page button and you answer within 24 hours, your messages are free for 72 hours.
• Volume tiers for utility and authentication, which only start at very high volumes.
• Undelivered messages. Meta charges on delivery, so blocked numbers and messages stopped by per-user marketing limits cost nothing.
• Markets outside the list. Meta publishes a rate for every country or region; the calculator carries the ones most readers need.

Ways to pay less

• Check the markup. Some platforms add around 15% to every message, others pass Meta's fees on at cost. At volume that difference is larger than the subscription.
• Categorise honestly. A genuine order update is utility, at a fraction of the marketing rate. Dressing a promotion up as utility gets templates re-classified, and repeat offenders restricted.
• Send fewer, better marketing messages. Segment by what the customer bought or asked for; unread and blocked messages also lower your quality rating.
• Let customers start the chat with a click-to-chat link or a chat button: replies are free up to the allowance and cheap after it.
