Score your stream quality by comparing your actual bitrate to the minimum recommended. See if your bitrate delivers acceptable, good, or excellent quality.
Not every bitrate delivers the same quality at every resolution. A bitrate that looks stunning at 720p might look terrible at 1080p because the same data is spread across four times as many pixels. This calculator scores your stream quality by comparing your actual bitrate to the minimum recommended for your resolution and frame rate.
The quality score ranges from 0 to 100+, where 100 means you're meeting the ideal bitrate for your settings. Scores below 60 indicate noticeable compression artifacts, especially during fast movement. Scores above 100 mean you have headroom — your stream likely looks great.
Use this tool to quickly assess whether your current OBS settings are appropriate or if you need to adjust your bitrate or resolution for better quality.
Gamers, streamers, and content creators benefit from precise stream quality vs bitrate data when optimizing their setup, planning purchases, or maximizing performance and value. Bookmark this tool and return whenever your hardware, games, or streaming requirements change.
Many streamers set their bitrate once and never revisit it, even after changing resolution or game genre. This calculator provides an instant quality assessment so you know if your current setup is delivering the experience your viewers deserve. It also helps when troubleshooting viewer complaints about stream quality. Instant results let you compare different configurations and scenarios quickly, helping you get the best performance and value from your gaming budget.
quality_score = (actual_bitrate / min_recommended_bitrate) × 100 Where: actual_bitrate = your current streaming bitrate in kbps min_recommended_bitrate = minimum bitrate for acceptable quality at your resolution/fps
Result: 75.00% quality score
At 4,500 kbps with a minimum recommendation of 6,000 kbps, your quality score is 75%. This means you're somewhat below optimal — the stream will look decent in slow scenes but show compression artifacts during fast action. Increasing to 6,000 kbps or dropping to 900p would improve quality.
Stream quality is a combination of resolution, bitrate, encoder efficiency, and content complexity. Higher resolution needs proportionally more bitrate. Faster action needs more bitrate than static scenes. More efficient encoders (H.265, AV1) need less bitrate for the same quality level.
Quality improvement from additional bitrate follows a logarithmic curve. Going from 2,000 to 4,000 kbps is a dramatic improvement. Going from 6,000 to 8,000 kbps is noticeable. Going from 10,000 to 12,000 kbps is barely perceptible. There's an optimal range for every resolution where you get the most quality per kbps spent.
Consider your average viewer's internet speed. If most viewers are on mobile or in regions with slower internet, a lower bitrate at lower resolution actually provides a better experience than a high bitrate that causes buffering. Platform transcoding (quality options) helps, but not all streamers get transcoding.
Above 80% is acceptable for most content. Above 100% is good. Above 120% is excellent. Below 60% will have noticeable artifacts during movement. Card games and desktop streams can look fine at 60%, while shooters need 100%+.
Use the Stream Bitrate Calculator on this site. Enter your resolution, fps, and motion factor. The result is your minimum recommended bitrate. Common values: 720p30 = ~2,500 kbps, 720p60 = ~4,500 kbps, 1080p30 = ~4,500 kbps, 1080p60 = ~6,000+ kbps.
Yes, and that's a good thing. It means you have more bitrate than the minimum needed. Scores up to about 150% show diminishing returns — beyond that, extra bitrate doesn't visibly improve quality but does use more bandwidth.
Bitrate isn't the only factor. Encoder preset, resolution scaling, and network stability all affect quality. A high bitrate with a "ultrafast" x264 preset looks worse than a moderate bitrate with a "faster" preset. Check all your encoding settings.
This calculator uses a bitrate-based score that assumes H.264. If you're using H.265 or AV1, the same bitrate produces higher effective quality because these codecs are more efficient. Your actual quality would be better than the score suggests.
For fast-paced games (FPS, racing), prioritize frame rate — 720p60 looks better than 1080p30. For slow content (strategy, desktop), prioritize resolution — 1080p30 looks sharper than 720p60. Match your settings to your content type.
