Then check that text, clock digits, and any movement remain clear, and that the stream stays stable. For a continuous stream, each 1 Mbps sustained uses about 10.8 GB per day or 324 GB in a 30-day month, before overhead and other VPS traffic.
How much bandwidth will a 24/7 stream use?
For a constant bitrate, estimate decimal gigabytes of outbound traffic with these calculations:
- GB per day ≈ bitrate in Mbps × 10.8
- GB per 30-day month ≈ bitrate in Mbps × 324
| Constant stream bitrate | Approximate traffic per day | Approximate traffic per 30-day month |
|---|---|---|
| 1 Mbps | 10.8 GB | 324 GB |
| 2 Mbps | 21.6 GB | 648 GB |
| 4 Mbps | 43.2 GB | 1,296 GB |
These are arithmetic estimates for a stream running continuously, not measurements or allowances published by a VPS provider. Actual metering can vary with protocol overhead, reconnects, unrelated VPS traffic, and the provider’s accounting method. Check your plan’s included outbound transfer, overage charges, and what happens when you reach its limit.
Viewer count and the VPS-to-platform upload
If your VPS sends one outbound feed to a platform’s ingest endpoint, the VPS’s upload traffic is broadly determined by that feed’s bitrate and running time, not by how many viewers watch. Viewer delivery is a separate traffic flow, generally handled by the platform; self-hosted distribution is different and can add traffic from viewers to your server.

Which settings reduce bandwidth?
1. Lower the video bitrate in measured steps
Reducing the encoded video bitrate reduces the stream’s outbound data, but can make details harder to see. For a study scene, inspect small on-screen text, clock digits, and motion rather than judging only a full-screen image. Lower one setting at a time and watch the platform’s stream-health indicators.
OBS’s connection troubleshooting guidance says a configured bitrate that the connection cannot sustain can cause dropped frames; it also cautions that a lower bitrate reduces video quality. Its suggested starting point of 75% of total upload speed is generic troubleshooting guidance, not a guaranteed VPS sizing rule. See the OBS connection troubleshooting guide.
2. Choose resolution and frame rate for the scene
A static or slowly changing study setup may not need the same temporal detail as fast-moving gameplay, but there is no established universal bitrate for a study stream. Test the actual image and choose the lowest resolution and frame rate that preserve the detail your viewers need.
YouTube’s current live-encoder table recommends these H.264 bitrates: 4 Mbps for 240p–720p at 30 fps, 6 Mbps for 720p at 60 fps, 10 Mbps for 1080p at 30 fps, and 12 Mbps for 1080p at 60 fps. These are platform recommendations for live ingestion, not minimums or study-stream-specific targets. Consult YouTube’s live encoder settings for the applicable settings and guidance.

Higher resolution and frame rate can require more bitrate; Twitch’s guidance also notes that higher frame rates require more encoding power. Those considerations matter if you stream to Twitch, but a stream’s destination determines which encoder recommendations and ingest requirements apply. See Twitch’s broadcasting guidelines.
3. Treat codec changes as a compatibility decision
Google for Developers’ current HLS ingestion documentation says HEVC generally provides 25% to 50% more data compression than H.264 at the same video quality. That is a documentation claim, not a guaranteed saving for every scene or encoder. The cited support is for HLS ingestion: confirm that your destination, ingest protocol, encoder, and playback workflow support the codec before switching. Read the YouTube HLS ingestion documentation.
Rank #4
4. Include audio in the total bitrate
Audio contributes to the stream’s total rate. YouTube’s guidance lists 128 Kbps for stereo audio; Twitch recommends AAC-LC at 96 Kbps for maximum compatibility. If your study stream needs only quiet ambience—or no audio—consider whether its audio track is necessary and use a setting compatible with the destination. There is no single best audio bitrate for every stream. Sources: YouTube live encoder settings and Twitch broadcasting guidelines.
5. Use a stable rate and verify the destination’s requirements
YouTube specifies constant bitrate (CBR) for RTMP/RTMPS live encoding, and Twitch also recommends CBR. A lower target does not guarantee a stable stream on every VPS route; check stream health and dropped frames after changing settings. Use the destination’s current encoder guidance rather than assuming one platform’s settings apply to another.

A practical test-and-adjust workflow
- Record the baseline. Note video and audio bitrate, resolution, frame rate, codec, observed outbound transfer, encoder load, and any dropped frames or reconnects.
- Estimate monthly transfer. Multiply the continuous stream bitrate in Mbps by 324 for an approximate 30-day total in GB. Account separately for other VPS traffic and leave room for metering differences.
- Change one setting at a time. Start with video bitrate. If the result is still more bandwidth than you want, test resolution or frame rate next. Change codec only after confirming compatibility.
- Run a representative stream. Include typical scene changes and audio, if used. YouTube recommends testing with audio and movement similar to the actual stream and monitoring stream health in its encoder guidance.
- Compare the results. Check image legibility, dropped frames or reconnects, encoder load, and observed outbound transfer. Restore a setting if the picture becomes hard to read or the stream becomes unstable.
- Confirm the VPS billing rules. Check your provider’s plan for transfer allowance, metering, and overage policy; those terms are plan-specific.
What bitrate does—and does not—control for viewers
The bitrate sent from the VPS is not necessarily the bitrate every viewer receives. YouTube says it transcodes a live stream into multiple output formats so viewers on different devices and networks can watch. OBS explains that Twitch transcoding is tiered and availability-dependent. Do not assume viewers can select a particular quality option without checking the destination and account availability.

Or let it run in the cloud
If your stream is a pre-recorded study video for YouTube, StreamNeo can loop an uploaded video or playlist from the cloud. The setup is: upload your recording or build a playlist, add your YouTube stream key, and go live. Your computer and home connection do not need to stay on. Each slot streams the upload as made, up to 4K 60fps, at one flat price per slot; StreamNeo automatically recovers if YouTube drops the stream. The first day is free with no card, one free day per account. The monthly option is $9.99 per month. StreamNeo is for YouTube and uploaded videos, not live camera input. See StreamNeo, or start your free day.
