How much does WhatsApp Business API cost?
Meta charges per template message delivered, priced by the template's category and the recipient's country. In Singapore that is S$0.0937 for marketing and S$0.0205 for utility and authentication. Meta bills your own WhatsApp Business account for these.
You will also pay your provider, the company that puts your number on the WhatsApp Business Platform and handles onboarding, templates and billing. That is a separate bill for the software, not for the messages. Voltade is one provider. SleekFlow, WATI and respond.io are others.
Replies you send inside a customer-initiated service window are free up to 1,000 a month for each business number. Since 1 October 2026, Meta charges for every one past that.
What changed for Singapore on 1 October 2026 is set out below in Singapore dollars. For every other market, read WhatsApp pricing from 1 October 2026, by market.
Rates below come from Meta's rate card effective 1 July 2026.
Here is the full breakdown, what is free, and how to keep the bill down.
WhatsApp Business API pricing structure
WhatsApp Business API costs have two components:
1. Meta's message fees – charged per message delivered
2. The software you run it with – billed by your provider
Pricing has been per message since July 2025
Meta changed WhatsApp Business API pricing in July 2025. The key shift:
| Before July 2025 | After July 2025 |
|---|---|
| Per-conversation pricing | Per-message pricing |
| 24-hour conversation window billing | Only template messages charged |
| Free-tier conversations included | Service messages free until 30 September 2026 |
This change benefits businesses with high customer engagement. From July 2025 you paid only for the template messages you sent. From 1 October 2026 Meta also charges for service messages past 1,000 a month on each business phone number.
WhatsApp message categories and Singapore pricing
Meta categorises messages into four types, each with different pricing:
| Category | Description | S$ per message |
|---|---|---|
| Marketing | Promotions, offers, product announcements, abandoned cart | S$0.0937 |
| Utility | Order confirmations, shipping updates, appointment reminders | S$0.0205 |
| Authentication | OTPs, verification codes, login confirmations | S$0.0205 |
| Service | Customer-initiated replies within 24-hour window | Free until 30 September 2026. From 1 October 2026, free up to 1,000 a month per number and S$0.0205 past that |
Rates from Meta's Singapore dollar rate card effective 1 July 2026, verified 24 September 2026.
Singapore moved off the regional Asia Pacific rate onto its own market-specific rate card on that
date. Utility and authentication are priced identically. Meta can change rates on the first day of each
quarter.
What changed in Singapore on 1 October 2026
Since 1 October 2026, Meta charges Singapore businesses for two kinds of message that cost nothing before. Both are priced at Singapore's utility rate, S$0.0205 per message delivered. Singapore's three headline rates did not move.
This reaches every business on the WhatsApp Business Platform that messages Singapore numbers, whether it connects to Meta directly or through a provider. Businesses on the free WhatsApp Business app are not affected.
Replies past 1,000 a month
Meta's pricing page, as it stood on 24 September 2026, states under its service rates effective 1 October 2026:
Each business phone number has one shared free tier of 1,000 delivered service messages per month. Both 1:1 and group service deliveries draw from this same free tier. A 1:1 delivery consumes one unit; a group send consumes one unit per delivered recipient. Meta charges for service messages after the free tier has been used.
Unused free messages do not roll over. The allowance is per business phone number, not per WhatsApp Business account: two numbers at 800 replies each pay nothing, while one number at 1,600 pays for 600. An inbox handling 5,000 replies a month on one number pays for 4,000 of them, S$82.00. Meta's notice on the change states that service messages have no volume tiers, so the rate does not fall with volume the way utility and authentication rates do.
Utility templates inside the window
A utility template sent inside an open window was free from 1 July 2025 to 30 September 2026. An order confirmation sent right after a customer asked about the order cost nothing. Since 1 October 2026 it is charged at S$0.0205. A business sending 500 of these a month goes from nothing to S$10.25.
An account with no payment method stops delivering replies
Meta's pricing page adds a condition to the free tier:
If you do not have a payment method for your WhatsApp Business account, Meta will deliver service messages within the shared free tier but not deliver them after the free tier has been used. To ensure continuity of your service messages, please ensure you have a payment method in Billing Hub.
Meta's notice on the change set 30 September 2026 as the date to have one on file. Without it, a busy number stops answering customers once its free 1,000 are used, until the next month.
Singapore dollar and US dollar accounts
The Singapore dollar has been one of Meta's billing currencies since 1 April 2026, and the S$ figures on this page come from Meta's Singapore dollar card. An older account that Meta still bills in US dollars pays the US dollar card instead, where the Singapore service and utility rate is US$0.0160.
What is free on WhatsApp Business API
Understanding what's free helps you optimise costs:
1. Replies inside a customer service window
When a customer messages you first, a 24-hour service window opens. The first 1,000 service messages you send inside that window each month are free on each business phone number, in any format, with no template approval needed. Meta charges for every reply past that.
2. Click-to-WhatsApp ads
When a customer messages you from a Click to WhatsApp ad and you reply within 24 hours, Meta opens a free entry point window that can stay open for up to 7 days. Every message you send in it is free.

Meta bills on these rates from 1 October 2026. Replies inside a customer's open 24-hour window are free for the first 1,000 per business phone number each month, then charged at the market's service rate. Utility templates sent inside that window are charged too, having been free until 30 September 2026. Read what changes.

Cost examples: real scenarios
Three businesses at different volumes, priced on Meta's Singapore dollar card. Each has one business phone number.
Scenario 1: small F&B business
| Item | Calculation | Until 30 September 2026 | From 1 October 2026 |
|---|---|---|---|
| Marketing messages | 500 × S$0.0937 | S$46.85 | S$46.85 |
| Utility messages | 200 × S$0.0205 | S$4.10 | S$4.10 |
| Service replies | 300, all inside the free 1,000 | S$0.00 | S$0.00 |
| Meta's bill | S$50.95 | S$50.95 |
Scenario 2: e-commerce store
| Item | Calculation | Until 30 September 2026 | From 1 October 2026 |
|---|---|---|---|
| Marketing messages | 2,000 × S$0.0937 | S$187.40 | S$187.40 |
| Utility messages | 1,500 × S$0.0205 | S$30.75 | S$30.75 |
| Service replies | 1,500, of which 500 past the free 1,000 × S$0.0205 | S$0.00 | S$10.25 |
| Meta's bill | S$218.15 | S$228.40 |
Scenario 3: high-volume business
| Item | Calculation | Until 30 September 2026 | From 1 October 2026 |
|---|---|---|---|
| Marketing messages | 10,000 × S$0.0937 | S$937.00 | S$937.00 |
| Utility messages | 5,000 × S$0.0205 | S$102.50 | S$102.50 |
| Service replies | 3,000, of which 2,000 past the free 1,000 × S$0.0205 | S$0.00 | S$41.00 |
| Meta's bill | S$1,039.50 | S$1,080.50 |
Scenario 1 stays inside the free 1,000, so nothing changes for it.
What the in-window utility charge adds
The three scenarios above count every utility template as sent outside a window, where it was always charged. Utility templates sent inside an open window are the second new charge. Two examples, covering only what changed on 1 October.
A business sending 2,000 marketing templates and handling 5,000 replies, on one number, with 500 utility templates sent inside open windows:
| Item | Calculation | From 1 October 2026 |
|---|---|---|
| Marketing templates | 2,000 × S$0.0937 | S$187.40 |
| In-window utility templates | 500 × S$0.0205 | S$10.25 |
| Replies past the free 1,000 | 4,000 × S$0.0205 | S$82.00 |
| Total | S$279.65 |
Of that, S$92.25 is new on 1 October. The same business paid S$187.40 in September for the identical volume. The marketing line is still two thirds of the bill, which is why template category matters more than either new charge.
A clinic under the allowance, with one number, handles 700 replies a month, sends 100 appointment confirmations inside open windows and 300 marketing templates for a seasonal offer. Its replies stay inside the free 1,000 and cost nothing. The 100 in-window confirmations go from free to S$2.05, added to a marketing bill of S$28.11 that did not change.
What to do now
1. Check that Billing Hub has a payment method. If a provider bills you, confirm with the provider which account the payment method sits on.
2. Count replies per phone number, not per account. WhatsApp Manager's messaging insights give the count. Meta allocates the free 1,000 per number.
3. Count in-window utility templates as a separate number. Filter your status webhooks for pricing type free_customer_service with category utility, or ask your provider for that count.
4. Check your template categories. A transactional message belongs in utility, at S$0.0205 against S$0.0937 for marketing. A high-volume template in the wrong category is still the most expensive mistake on the platform.
5. Answer in fewer messages. Past the free 1,000, every reply is charged, so an enquiry settled in three messages instead of eight saves five charges.
Six ways to reduce WhatsApp API costs
1. Maximise the 24 hour service window
When a customer messages you, answer inside the 24 hour service window. The first 1,000 replies there each month on each number are free.
2. Use free entry points
Drive traffic through:
3. Categorise messages correctly
Utility messages (S$0.0205) cost about 78% less than marketing messages (S$0.0937). If your message is truly transactional (order update, appointment reminder), template it as utility, not marketing.
4. Segment your audience
Send marketing templates to the customers most likely to reply, rather than to your whole database. Every template you do not send is one Meta does not charge for.
Cost is not the only reason. Blasting an unsegmented list is also the behaviour most likely to get a number restricted, which is a more expensive problem than the messages themselves. If that has already happened, see how to restore a blocked WhatsApp account.
5. Use AI to handle service conversations
An AI agent answers common questions as they arrive, after hours included, inside the service window, where the first 1,000 service messages a month on each number are free.
6. Consolidate messages
Instead of sending three separate updates, combine them into one message where possible.
WhatsApp vs email vs SMS: cost comparison
| Channel | Cost per message |
|---|---|
| WhatsApp (marketing) | S$0.0937 |
| WhatsApp (utility) | S$0.0205 |
| Under S$0.01 | |
| SMS | About S$0.05 |
The WhatsApp rows are Meta's Singapore dollar rates. Email is Mailchimp's Standard plan at its full monthly send allowance, and SMS is Bulk SMS Singapore's published rate.
What the higher price buys
A WhatsApp template costs more than an email. What the price buys:
What you pay a provider
Beyond Meta's message fees you pay your Business Solution Provider for the software. What that buys, at any provider:
Typical BSP pricing
| Provider | Plans, billed yearly |
|---|---|
| Wati | Growth S$119 a month, Pro S$329 a month, Business custom |
| SleekFlow | Pro S$199 a month, Premium S$479 a month |
| respond.io | Starter US$79 a month, Growth US$159 a month, Advanced US$279 a month |
| Volty | Seats included on every plan, priced on the Volty pricing page |
Each provider's prices are in the currency it publishes: Wati and SleekFlow in Singapore dollars, respond.io in US dollars.
WhatsApp Business app or Volty
Meta offers two ways to run WhatsApp for a business. The WhatsApp Business app runs on your phone, and messages sent from it are free. Volty runs on the WhatsApp Business Platform, Meta's API, and one number can use the app and the Platform at the same time.
| Feature | WhatsApp Business app | Volty on the WhatsApp Business Platform |
|---|---|---|
| Integrations with your systems | The app's own business tools: catalogue, labels, quick replies, greeting and away messages | Google Drive, Docs and Sheets, Shopify, Plato Medical and Microsoft Outlook, plus any system with an MCP server or an API key |
| Email as a second channel | WhatsApp only | A Microsoft 365 or Outlook mailbox, which Volty reads and replies from. Gmail is not supported |
| What it costs | Messages sent from the app are free | A monthly Volty plan (see pricing), plus Meta's per-message charges |
| Who replies | You and your team, on your phone and linked devices | Volty replies, or drafts replies for your team to send. A teammate can take over any conversation |
| Numbers and devices | Your phone, plus up to four linked devices | Several numbers in one workspace, a web inbox on any device, and the WhatsApp Business app still working on the same number |
| Templates and broadcasts | Broadcast lists and marketing messages from the app's messaging tools | Volty submits your message templates to Meta for approval. A Volty broadcast sends one approved template once to one audience (chosen contacts, segments, everyone, or a spreadsheet), leaving out contacts who opted out. When a customer's 24 hour window has closed, Volty follows up one to one with an approved template |
| The free 1,000 service messages | Does not apply: messages sent from the app sit outside the service window | 1,000 free a month per number, then S$0.0205 each in Singapore. |
The app suits an owner answering every chat from one phone, and Volty suits a team that wants WhatsApp tied to its mailbox and systems.
Every Volty plan carries every feature and includes seats, monthly active contacts, AI credits and Volty requests, so the plan you pick reflects how much of each you need rather than which features you get. See full pricing.

Frequently asked questions
Is WhatsApp Business API free to use?
No. You pay Meta's per-message fees plus your BSP's platform charges. The first 1,000 service messages delivered a month on each business phone number are free, and Meta charges for every one past that.
What is the cheapest type of WhatsApp message?
Service messages (replies inside a customer-initiated service window) are free up to 1,000 delivered a month on each business phone number, and Meta charges for every one past that. For template messages, utility and authentication are cheapest, at S$0.0205 each in Singapore.
Do I pay for messages that fail to deliver?
No. You only pay for messages that are successfully delivered to the recipient's device.
Does Meta bill WhatsApp in Singapore dollars?
Yes. The Singapore dollar has been one of Meta's billing currencies since 1 April 2026, and Meta publishes Singapore rates in it: S$0.0937 for marketing and S$0.0205 for utility and authentication. An older account that Meta still bills in US dollars pays Meta's US dollar rates instead.
What happens if my WhatsApp Business account has no payment method?
Meta delivers service messages within each number's free 1,000 a month and stops delivering them after that. Meta's notice set 30 September 2026 as the date to have a payment method on file. Add one in Billing Hub, or ask your provider which account the charge lands on.
Are authentication messages cheaper than utility messages in Singapore?
No. Meta prices authentication and utility identically in every market on its rate cards. In Singapore both are S$0.0205 per message delivered.
Why did Singapore's WhatsApp rates change on 1 July 2026?
Until then Singapore shared a price with the rest of Asia Pacific. On 1 July 2026 Meta gave Singapore its own rate card, and utility and authentication rose from S$0.0145 to S$0.0205. Marketing did not change. Singapore's rates now move independently of Australia, Japan, Thailand and the rest of the region, and Singapore was not one of the nine markets that got their own rates on 1 October 2026.
Are there volume discounts?
Yes, for utility and authentication templates. Meta lowers those rates in tiers as a business portfolio sends more of them in a month, and the tiers reset monthly.
Can I switch BSPs if I find cheaper pricing?
Yes. Your WhatsApp Business Account can be migrated between BSPs. Switching platforms means retraining staff and rebuilding automation workflows.
Is WhatsApp cheaper than traditional CRM?
For customer communication, yes. HubSpot Sales Hub Professional starts at S$126 a seat a month and Salesforce Pro Suite at US$100 a user a month, and you still pay for email and SMS sending on top. Volty includes seats on every plan, and one plan price carries the CRM, the WhatsApp channel, the AI agent and the integrations. See pricing.
