A Clear Guide to Twilio WhatsApp Pricing (2025)

Planning your budget for the WhatsApp Business API? This guide provides a clear breakdown of Twilio's pricing model, including the crucial per-message fee, so you can make an informed decision without any surprises.

Understanding Twilio's Model: The Crucial Per-Message Fee

While most WhatsApp Business API providers follow Meta's standard per-conversation pricing, Twilio's approach has a key difference. This is especially important to understand if your use case involves conversational interactions, like customer support or automated chatbots.

The Key Takeaway: Twilio applies a $0.005 fee for every message you send within a 24-hour conversation window. This is charged *in addition* to Meta's standard conversation fee. For chat-heavy applications, this model can significantly impact the total cost.

This means your total cost on Twilio isn't a single charge, but a combination of three distinct components.

The Twilio Pricing Formula

Total Cost=
1.(Twilio's Per-Message Fees × Number of Messages)($0.005/message)
+
2.Meta's Per-Conversation Fee(varies by country)
+
3.Your Monthly Number Fee(~$1-2/mo)

The cost scales with every message you send, making it unpredictable for chat-heavy use cases.

The 3 Components of Twilio WhatsApp Pricing

Let's break down exactly where your money goes.

Component 1: Twilio's Per-Message Usage Fee

This is Twilio's primary markup, based on message volume.

  • Session Message Fee: A flat $0.005 for every message your business sends in an active 24-hour window.
  • Template Message Fee: A flat $0.005 for every template message used to start a conversation (this is on top of Meta's fee for the conversation).

Component 2: Meta's Conversation Fees (Paid Through Twilio)

This is the standard base cost from Meta that all providers pass on. A single fee opens a 24-hour window, and the price varies by country and who initiates it.

Component 3: Twilio's Monthly Number Fee

A small, predictable charge for renting your WhatsApp-enabled virtual number, typically around $1-2 per month.


Cost Calculation: A Real-World Chatbot Example

Let's see how these components work together. Imagine a customer in India starts a chat with your support bot, and they exchange 10 total messages to resolve an issue (5 from the user, 5 from your bot).

Twilio

1. Meta's Fee

1 Service Conversation × ~$0.0036 = $0.0036

2. Twilio's Per-Message Fee

5 messages × $0.005/message = $0.025

Total Twilio Cost

$0.0286
SendZen

1. Meta's Fee

1 Service Conversation × ~$0.0036 = $0.0036

2. SendZen's Platform Fee

5 messages × $0.00/message = $0.00

Total SendZen Cost

$0.0036

The Result: For this one simple support chat, Twilio's total cost is almost 8 times higher than SendZen's. Now imagine this for hundreds or thousands of customer conversations per month.

Choosing the Right Model: Pay-Per-Message vs. Flat-Rate

Twilio's pay-per-message model can lead to unpredictable costs for businesses with high message volumes. Every helpful reply from your support team or automated response from your chatbot directly adds to the monthly bill.

In contrast, flat-rate models offered by providers like SendZen are designed for predictability. Our plans include a large volume of messages, allowing you to engage in conversations freely without worrying about fluctuating costs. This provides clear budget certainty and encourages deeper customer engagement.
