WhatsApp message cost calculator

A WhatsApp cost estimate is one multiplication: per-message rate × billable messages. You take Meta's published rate for your recipient market and category, and multiply by the monthly volume you send. Nothing is added on top — that's Meta's fee, not a bitbybit charge. Three things shape the real bill:

• Service messages are billable since October 1, 2026. When a customer messages you first, you get a 24-hour window for free-form replies. The first 1,000 of those per business phone number each month are free; after that each is billed at the market rate. Utility templates sent inside the window are billable too.
• The 72-hour free entry-point window. When a customer reaches you through a click-to-WhatsApp ad or a Facebook Page call-to-action button and you reply within 24 hours, Meta opens a 72-hour window in which template messages are free. See the WhatsApp integration page.
• Volume-tier discounts. Meta offers lower utility and authentication rates as monthly volume grows (marketing is excluded). Enter the standard rate and treat the result as an upper bound.

Meta charges per delivered template message; the price changes by recipient country and category. Marketing is the most expensive; utility, authentication, and service (after the monthly free allowance) are far cheaper. Because Meta revises per-market rates regularly, this tool doesn't hard-code prices — you supply the current rate from Meta so the estimate reflects today's number.

For the exact figure in your market and currency, use the always-current table onMeta's WhatsApp Business Platform pricing page(developer reference: Meta's pricing docs). Meta bills in your account's local currency. Some markets also carry a separateauthentication-international ratefor cross-border one-time-passcode messages.

No. bitbybit passes Meta's published per-message rates straight through, with no markup. You pay Meta's rate for the messages you send, plus a flat platform fee for bitbybit — theAI Studio agent engine, the bitChat conversation surface, and the bitCRM customer record — that doesn't change with your message volume. Plans start at $99/mo for bitChat Growth and $299/mo for the Pro Bundle; see the pricing page. bitbybit is an Official Meta Tech Partner running directly on the WhatsApp Cloud API, so the Meta rates you estimate here are the rates that apply — with no reseller markup.

Per message — on July 1, 2025, Meta retired the older 24-hour conversation-based model and now bills WhatsApp Business template messages per delivered message. Each message’s price is set by the recipient’s country and the message category — marketing, utility, authentication, or service. Since October 1, 2026, service messages (free-form replies inside the 24-hour service window) are billable after the first 1,000 per business phone number each month, and utility templates sent inside that window are billable too.

Since October 1, 2026, fewer than before. Incoming messages from customers are free. The first 1,000 service messages (free-form replies inside the 24-hour service window) per business phone number each month are free; after that, each one is billed at the market rate, and the allowance does not roll over. When a customer reaches you through a click-to-WhatsApp ad or a Facebook Page call-to-action button and you reply within 24 hours, Meta opens a 72-hour free entry-point window in which messages are free. Everything else — including utility templates sent inside the service window — is billed at Meta’s per-message rate for the recipient’s market.

Mostly for reasons in your favor. The calculator uses the flat rate you enter, but Meta applies volume-tier discounts to utility and authentication messages at higher monthly volumes, and the estimate excludes free-entry-point messages and assumes one business phone number for the 1,000 free service messages. Going the other way, your category mix may differ from what you entered, and Meta updates rates by market periodically. Treat this as a planning estimate, not an invoice, and confirm live rates on Meta’s official WhatsApp pricing page.
