Pay-As-You-Go

This document describes how audio call, video call, and interactive live audio/video streaming are billed on a monthly basis.
If you have a contract with TRTC, the billing details in the contract will apply.
Note:
Aggregate video resolution applies to accounts whose first TRTC application is created on or after October 27, 2021.

Billing Details

TRTC adds up the audio and video durations of all projects under your account at the end of each month. Note that video durations are classified into four categories based on "aggregate video resolution" and are priced differently. TRTC offers each account a 10,000-minute free package per month. The system will first deduct your usage using the free minutes and the bonus minutes of packages you purchase. The remaining durations multiplied by their unit prices are your total pay-as-you-go cost for the month.

Formula

Monthly cost = Audio duration x Unit price of audio duration + Video durations of different categories x Unit price of the corresponding category

Audio and video durations

The audio/video duration of a call is the sum of the durations of all users.
Video duration: If a user subscribes to video streams, regardless of whether they also receive audio streams, their duration will only be billed as video duration.
Audio duration: If a user does not subscribe to video streams, their duration will be counted as audio duration, regardless of whether they subscribe to audio streams. In other words, if a user subscribes to video streams, their duration will be billed as video duration; if a user does not subscribe to any stream, their duration will still be billed as audio duration.

For example, if a user subscribes to two 960 x 720 video streams, the user's aggregate video resolution is 960 x 720 + 960 x 720 = 1,382,400, which falls in the category of FHD.

Billing Example 1

This section uses an example to show you how TRTC calculates pay-as-you-go fees.
Assume that six users entered a room at the same time and communicated over video for 60 minutes.
There were three anchors (A, B, and C) in the room. The video resolution of A was 960 x 720, and that of B and C were both 640 x 480. Two of the audience members subscribed to the video streams of all anchors, while the other subscribed to audio only. Anchor A also shared the screen at a resolution of 1920 x 1080.

There were four anchors (A, B, C, and D) in the room. The video resolution of A, B, and C was 480 x 480, while D published only audio. One of the audience members subscribed to the video streams of all anchors, and the other subscribed to audio only.

Must-Knows

There are some other matters that merit your attention.

Price calculator

You can use the TRTC Price Calculator to estimate your cost.

Accuracy of durations

TRTC calculates durations in seconds and converts monthly cumulative seconds to minutes for billing. Specifically, it adds up the audio and video durations (in seconds) for a month and divides them by 60. The results are rounded up to the nearest whole number. For example, if your account consumed 59 seconds of audio duration and 61 seconds of video duration in a month, you would be billed for 1 minute of audio duration and 2 minutes of video duration. The margin of error for monthly durations is smaller than 1 minute.

Dual-stream resolution

In the dual-stream mode, a user's resolution is calculated as follows:
If the user subscribes to the high-quality stream, the resolution of the high-quality stream set by the sender will be used for the calculation of the aggregate resolution.
If the user subscribes to the low-quality stream, the actual resolution of the video received will be used for the calculation of the aggregate resolution.

Resolution of screen sharing

The resolution set in TRTCVideoEncParam is used for the billing of screen sharing duration. For how to set the resolution, see the documents below:
All platforms (C++): startScreenCapture
Android: startScreenCapture
On web, a target resolution may be unattainable due to device and browser restrictions, in which case the browser will adjust the resolution automatically to make it as close as possible to the target, and the actual resolution will be used for billing. For details, see setScreenProfile.

Robot duration

If a media processing task (recording, moderation, relay, etc.) is initiated for a room, the system will assign a robot to the room (if multiple tasks are initiated, there will be multiple robots). The robot will enter the room as a user and will subscribe to streams of the room. This will incur audio/video duration fees.
The duration of subscription generated by the robot pulling and relaying the stream to the RTC room is billed normally. Since it does not pull the stream in the room, only the duration of audio received in the room is charged.
In other cases (for example, if you relay to another TRTC room or a third-party platform), the robot's audio/video duration will be billed.

Cost of using other products/services

If you use other Tencent Cloud products or TRTC services that are not audio/video call or interactive live streaming, for example, on-cloud recording, additional fees will be incurred. For details, see the billing documents of the corresponding products or TRTC services.
