WhatsApp Conversation Fees: The Complete Billing Breakdown

The billing unit is the conversation

Since November 2024, Meta charges per conversation: a 24-hour session between your business and one customer. The price of the session depends on which category opened it — not on how many messages you send inside it.

• One customer, one 24-hour session = one conversation
• The opening message decides the category
• Messages inside the session do not multiply the bill
• A customer message resets the 24-hour window

The four categories and US rates

US rates give a clean picture of the relative costs. Rates differ by destination country, but the hierarchy holds everywhere.

• Marketing: $0.025 per conversation in the US — offers, launches, announcements
• Utility: $0.004 per conversation — order updates, reminders, account changes
• Authentication: $0.004 per conversation — one-time passwords and login codes
• Service: free — customer-initiated conversations inside the 24-hour window

What makes a conversation marketing

Category follows purpose, not effort. A reminder with a promotional line is a marketing conversation — and bills at the marketing rate.

• Promotional content of any kind moves the conversation to marketing
• Entry-point ads bill as marketing by default
• Keep reminders and updates purely factual to stay in utility
• Category mistakes are the most common billing error

The 24-hour window and the free path

When a customer messages you, a service conversation opens and replies are free for 24 hours. Answer promptly, do the transactional work in the window, and only use templates when the window closes.

• Every customer message resets the window
• Free-form replies are free inside the window
• A template inside the window re-bills the conversation by its category
• The window is the cheapest customer service tool you own

Country tiers change everything

The same message costs different amounts by destination. The US sits in a higher tier; India is among the lowest-cost destinations. Segment campaigns by country and check current rates before large sends.
