Official Meta rates in USD and COP effective July 1, 2026, verified July 31, 2026. Includes 38 markets and regions. Meta may update its rate card at the beginning of each quarter.

Meta charges for each delivered template. Marketing uses the list rate; utility and authentication can decrease through monthly tiers aggregated at business-portfolio level. Service messages, non-template messages and certain utility templates inside an open customer-service window do not incur a Meta charge. Free entry points may open a 72-hour no-charge window.

This estimate excludes your OneChat plan, taxes and third-party charges. Meta determines international-authentication eligibility and the final applicable tier.
