How Much Does the WhatsApp Business API Cost in 2026?

But first, what are you actually paying for?

A WhatsApp Business Platform setup has two separate bills.

• Meta's messaging charges. Meta bills per delivered message. Messages your customers send you are always free, whether it’s a first enquiry or a tenth follow-up. Meta only charges for what you send back, and only once it is delivered, so a busy inbox costs nothing on its own.
• Your provider. This covers the software, the API, templates, reporting and support you send with. On Kero, plans start at £49 a month and include SMS, RCS and WhatsApp on one platform. Meta’s messaging charges are billed separately from your Kero plan.

How does Meta price each message?

Every message you send falls into one of four categories (Meta calls these templates), and each category has its own rate in each country.

• Marketing: promotions, offers and re-engagement messages. Always charged, and usually the most expensive category.
• Utility: order confirmations, delivery updates and appointment reminders. Always charged, whether sent inside or outside the customer service window.
• Authentication: one-time passwords and login codes. Always charged.
• Service: free-form replies sent inside the 24-hour customer service window. The first 1,000 each month are free on every phone number; after that, each message is charged at the utility rate for the recipient’s country.

Only delivered messages are billed. Rates depend on the recipient’s country, not where you are sending from. Higher monthly volumes can qualify for discounted rates on marketing, utility and authentication messages, but not on service messages.

What changed on 1 October 2026?

Until 30 September, service messages (free-form replies inside the 24-hour window) were free and uncapped, and so were utility messages sent inside that window. From 1 October, Meta charges for both. The free 1,000 allowance covers service messages only, so a utility message is billable from the first one, even when the customer messaged you first.

The result is that the cost of WhatsApp now depends mostly on how many messages you send, not on who started the conversation. We covered the change in detail in New WhatsApp Business Platform price changes: charging user-initiated conversations.

What does a service message cost?

A service message costs the same as a utility message in the recipient's country. At the time of writing:

• South Africa: R0.16 ($0.0095, £0.0069) per message
• United Kingdom: $0.0220 (£0.0159) per message
• North America: $0.0034 (£0.0025) per message

Meta reviews its rates from time to time, so check the WhatsApp pricing calculator for today's figures before you budget.

A worked example

Say a South African business receives 400 customer enquiries a month and sends three replies to each.

1. That is 1,200 service messages. The first 1,000 are free, and 200 are billable. At R0.16 each, the replies cost R32.
2. The business also sends an order confirmation to each customer as a utility message. The free allowance does not cover these, so all 400 are billable, which comes to R64.
3. Meta's charges for the month come to R96, before any marketing messages and before your provider's subscription.

A team running a chatbot, or replying many times per conversation, uses up the free 1,000 much faster, so count messages per phone number, not conversations.

How do you estimate your own costs?

Open the WhatsApp pricing calculator, choose the countries you send to and enter your expected monthly volume for each message type. Add your provider's plan from the pricing page, and you have a monthly figure you can budget against.

Five ways to keep WhatsApp costs down

1. Track service messages per phone number. The free 1,000 applies to each number separately and does not roll over to the next month.
2. Combine updates where you can. One message that confirms an order and gives the delivery date costs less than two.
3. Categorise each message correctly. Meta reviews how messages are categorised and can reclassify a utility message whose content is promotional, which moves it to the marketing rate.
4. Keep a payment method on file. Without one, Meta delivers your first 1,000 service messages per number each month and then stops delivering service messages.
5. Send each message on the channel that suits it. Not every message needs WhatsApp. With Kero, you can send the same message by RCS, WhatsApp or SMS from one platform, and choose the order the channels are tried in.

Frequently asked questions

Is the WhatsApp Business Platform free?

No. Messages from your customers are free, and each phone number gets 1,000 free service messages a month. Marketing, utility and authentication messages (and service messages beyond the first 1,000) are charged per delivered message.

Do I pay for messages customers send me?

No. Incoming messages are always free.

Is the WhatsApp Business App the same as the Platform?

No. The WhatsApp Business App is a free app for small businesses that reply from a phone. The Platform, which includes the API, is built for sending at scale through software, and it is charged per message. Read What is the difference between WhatsApp Business App and WhatsApp Business Platform? for the full comparison.

Are Meta's charges included in a Kero plan?

No. Your Kero plan covers the platform and the Messaging API. Meta's messaging charges depend on destination and message type and are billed separately. The WhatsApp pricing calculator shows them.

Will WhatsApp prices change again?

Possibly. This is the second big change in under two years, after the move from conversation-based to per-message pricing in July 2025. We update this article and the calculator when Meta publishes new rates.
