How much does Twilio pay per call?

Let’s break down how much Twilio charges per call so you can get a clear picture without getting lost in the tech jargon.

Understanding Twilio’s Call Pricing

Twilio offers a variety of communication services, and when it comes to voice calls, the cost can vary based on several factors. Here's a simple overview to help you grasp the basics.

Types of Calls

• Inbound Calls: These are calls that come to your Twilio number.
• Outbound Calls: These are calls that your Twilio number makes out to other numbers.

Pricing Factors

1. Country and Region: The cost per call depends on where the call is being made to or from. For example, calls within the United States are generally cheaper than international calls.
2. Type of Number: Whether you're using a local number, toll-free number, or mobile number affects the pricing.
3. Call Duration: Charges are typically based on the length of the call, measured in minutes.
4. Additional Features: Features like call recording, transcription, or using Twilio's advanced APIs can add to the cost.

Example Pricing

To give you a ballpark idea, here are some typical costs for voice calls using Twilio in the United States:

• Inbound Calls: Approximately $0.0085 per minute.
• Outbound Calls to the US: Around $0.013 per minute.
• Outbound International Calls: Varies widely, e.g., $0.020 per minute to Canada, $0.040 per minute to the UK, and higher rates for other countries.

Note: These prices are subject to change and can vary based on specific needs and volumes. Always check Twilio’s Pricing Page for the most accurate and up-to-date information.

How to Calculate Your Costs

Let’s say you’re running a support center and expect 1,000 inbound calls per month, each lasting an average of 5 minutes. Here’s a quick calculation:

• Inbound Call Cost: 1,000 calls * 5 minutes * $0.0085 = $42.50
• Outbound Call Cost: If each inbound call leads to one outbound call of the same duration: 1,000 calls * 5 minutes * $0.013 = $65
• Total Monthly Cost: $42.50 + $65 = $107.50

Tips to Optimize Costs

• Choose the Right Number Type: Select the number type that best fits your needs to avoid unnecessary charges.
• Monitor Usage: Keep an eye on your call volumes and durations to manage expenses effectively.
• Leverage Twilio’s Features: Utilize features like call forwarding and routing to optimize call flows and reduce costs.
