Pricing Scenarios


Azure Communication Services is currently in public preview. This preview version is provided without a service-level agreement, and it's not recommended for production workloads. Certain features might not be supported or might have constrained capabilities. For more information, see Supplemental Terms of Use for Microsoft Azure Previews.

Prices for Azure Communication Services are generally based on a pay-as-you-go model.

Voice/Video calling and screen sharing

Azure Communication Services allow for adding voice/video calling and screen sharing to your applications. You can embed the experience into your applications using JavaScript, Objective-C (Apple), Java (Android), or .NET client libraries. Refer to our full list of available client libraries.


Calling and screen-sharing services are charged on a per minute per participant basis at $0.004 per participant per minute for group calls. To understand the various call flows that are possible, refer to this page.

Each participant of the call will count in billing for each minute they're connected to the call. This holds true regardless of whether the user is video calling, voice calling, or screen-sharing.

Pricing example: Group audio/video call using JS and iOS client libraries

Alice made a group call with her colleagues, Bob and Charlie. Alice and Bob used the JS client libraries, Charlie iOS client libraries.

  • The call lasts a total of 60 minutes.
  • Alice and Bob participated for the entire call. Alice turned on her video for five minutes and shared her screen for 23 minutes. Bob had the video on for the whole call (60 minutes) and shared his screen for 12 minutes.
  • Charlie left the call after 43 minutes. Charlie used audio and video for the duration of time he participated (43 minutes).

Cost calculations

  • 2 participants x 60 minutes x $0.004 per participant per minute = $0.48 [both video and audio are charged at the same rate]
  • 1 participant x 43 minutes x $0.004 per participant per minute = $0.172 [both video and audio are charged at the same rate]

Total cost for the group call: $0.48 + $0.172 = $0.652


With Communication Services you can enhance your application with the ability to send and receive chat messages between 2 or more users. Chat client libraries are available for JavaScript, .NET, Python and Java. Refer to this page to learn about client libraries


You're charged $0.0008 for every chat message sent.

Pricing example: Chat between two users

Geeta starts a chat thread with Emily to share an update and sends 5 messages. The chat lasts 10 minutes wherein Geeta and Emily send another 15 messages each.

Cost calculations

  • Number of messages sent (5 + 15 + 15) x $0.0008 = $0.028

Pricing example: Group chat with multiple users

Charlie starts a chat thread with his friends Casey & Jasmine to plan a vacation. They chat for a while wherein Charlie, Casey & Jasmine send 20, 30 and 18 messages respectively. They realize that their friend Rose might be interested in joining the trip as well, so they add her to the chat thread and share all the message history with her.

Rose sees the messages and starts chatting. In the meanwhile Casey gets a call and he decides to catch up on the conversation later. Charlie, Jasmine & Rose decide on the travel dates and send another 30, 25, 35 messages respectively.

Cost calculations

  • Number of messages sent (20 + 30 + 18 + 30 + 25 + 35) x $0.0008 = $0.1264
