WhatsApp API pricing calculator
Pick your customers' country, the rate period and how many messages you send each month per category. We estimate Meta's cost using its official rates. From October 1, 2026, replies inside the 24-hour window are billed too, after 1,000 free service messages per month per number. With ChatSales you pay exactly this to Meta, with no markup.

Example: a typical month in Mexico
A business sending 1,000 marketing and 2,000 utility templates a month paid Meta US$47.50 until 30 September 2026 (1,000 × US$0.0305 + 2,000 × US$0.0085). From 1 October 2026 the Mexico marketing template costs US$0.0397 and replies inside the 24-hour window are billed at the utility rate after the first 1,000 free per number each month: with 3,000 replies you pay (3,000 − 1,000) × US$0.0085 = US$17.00, and the same month costs US$73.70. ChatSales adds nothing to that bill.
How to pay less per message
- Use utility templates for order and payment updates; they cost less than marketing ones.
- Segment your broadcasts: send each promotion only to people who want it.
- Bring in conversations with Click-to-WhatsApp ads: if the customer messages from the ad on the mobile app and you reply within 24 hours, a free window of up to 7 days opens.
- Put each reply in one complete message: from 1 October 2026 each number gets 1,000 free service messages a month, and after that every reply is billed at the utility rate.
0% markup on Meta's fees
You pay for messages directly to Meta with your own payment method. ChatSales doesn't resell messages or add a markup.
