Streaming Bitrate Calculator

Calculate the optimal streaming bitrate for your platform and content. Get recommendations for video and audio bitrate, required upload speed, and data usage estimates for Twitch, YouTube, and more.

Video Bitrate = Base Resolution Bitrate × FPS Multiplier × Content Multiplier Audio Bitrate = 160 kbps (standard) Total Bitrate = Video Bitrate + Audio Bitrate Data Usage (MB/hour) = (Total Bitrate ÷ 8) × 3600 ÷ 1024 Upload Speed Required = Total Bitrate × 1.3 (for stability)
Example: 1080p @ 60fps, Medium Motion gaming on Twitch Base: 6000 kbps × 1.5 (60fps) × 1.0 (medium) = 9000 kbps Audio: 160 kbps Total: 9160 kbps (capped at 6000 kbps by Twitch) Upload needed: 6 × 1.3 = 7.8 Mbps Data/hour: (6000 ÷ 8) × 3.6 ÷ 1024 = 2.64 GB/hour

What bitrate should I use for streaming?

For 1080p @ 60fps on Twitch, use 4500-6000 kbps. YouTube allows higher bitrates (up to 51 Mbps for 4K), while Facebook Gaming caps at 4000 kbps. Always stay below your platform's maximum and ensure your upload speed is at least 1.3x your bitrate.

How much upload speed do I need for streaming?

Your upload speed should be at least 1.3x your streaming bitrate for stability. For 1080p @ 60fps (6000 kbps), you need at least 7.8 Mbps upload. Add extra if you're gaming online simultaneously.

What's the difference between CBR and VBR?

CBR (Constant Bitrate) maintains the same bitrate throughout, recommended for streaming. VBR (Variable Bitrate) adjusts based on complexity, better for recording but can cause buffering in live streams.

How does FPS affect bitrate?

Higher FPS requires higher bitrate to maintain quality. 60 FPS needs about 1.5x the bitrate of 30 FPS for the same resolution. 120 FPS needs 2x the bitrate but is rarely supported by streaming platforms.

Why is my stream buffering?

Common causes: insufficient upload speed, bitrate too high for your connection, unstable internet, or exceeding platform limits. Reduce bitrate by 10-20% or lower resolution/FPS if buffering persists.
