WhatsApp Business API Pricing Guide: What Does It Really Cost?

What is the cost of WhatsApp Business API?

There is no fixed per-message price. Meta bills the WhatsApp Business API per 24-hour conversation, and your effective cost depends on three things: the conversation category, the recipient's country, and any markup your provider charges.

Meta's conversation-based pricing

When you send the first message in a thread (or a user messages you), a 24-hour conversation window opens. Every message inside that window counts as one billable conversation, regardless of how many messages are exchanged. Conversations fall into four categories:

• Marketing — promotions, offers, newsletters. Highest rate.
• Utility — order updates, receipts, account alerts.
• Authentication — one-time passwords and verification codes.
• Service — user-initiated support replies. First 1,000 per month are free.

Rates vary by country. As of 2026, marketing conversations in India cost roughly $0.0099, in Brazil around $0.0625, and in the US around $0.025. Meta publishes the current rate card in their Business Platform documentation.

Provider markups and platform fees

Most teams don't talk to Meta directly — they go through a Business Solution Provider (BSP) or a self-hosted gateway. BSPs typically add one or more of:

• A flat monthly platform fee (often $25–$500 depending on tier).
• A per-conversation markup on top of Meta's price.
• Per-seat fees for inbox / agent licenses.
• Charges for extras like template approvals, analytics, or media storage.

A self-hosted gateway (like the one WA Linked SMS connects to) removes the per-conversation markup — you still pay Meta's underlying rate, but the platform layer is yours.

How to estimate your monthly bill

1. Forecast conversations per month, split by category and country.
2. Multiply by Meta's published rate for each row.
3. Subtract the 1,000 free service conversations.
4. Add your provider's platform fee and any per-message markup.

Example: 5,000 utility conversations in the US at ~$0.0140 ≈ $70 from Meta, plus a $99 platform fee, comes to roughly $169 per month — before marketing volume.

WhatsApp API vs SMS pricing

SMS is billed per segment (160 GSM characters). WhatsApp is billed per 24-hour conversation, so a long support thread that would cost 10+ SMS segments still counts as one WhatsApp conversation. For richer, longer interactions WhatsApp is usually cheaper; for one-off transactional pings to many recipients, SMS can win on simple math.
