TRTC calculates relay usage based on the peak bandwidth (Mbps) used to relay streams by all applications under your account during each billing cycle, which is monthly by default.

Billing Examples

Example

Suppose the bitrate of a stream you published to the CDN was 500 Kbps (the sum of the audio bitrate and video bitrate), and there were 300 relaying tasks at the peak on that day.
Daily peak bandwidth = 500 (Kbps) x 300 = 150,000 (Kbps) =150 Mbps.
The monthly peak bandwidth fee for relaying to CDN = 18.99 (USD/Mbps/month) × 150 (Mbps) = 2848.50 USD.
