Bitrate & bandwidth calculator
Convert stream bitrate and concurrent listeners into peak Mbps and monthly transfer estimates.
Quick presets
Typical use
Peak stream bandwidth
19.2Mbps
192 kbps × 100 listeners
Estimated monthly transfer
6221GB
≈ 207 GB/day at your hours setting
Peak Mbps assumes every concurrent listener is connected at the selected bitrate. Monthly GB assumes that peak stays online for the hours/day you set across a 30-day month—real usage is usually lower.
Bitrate calculator FAQ
Bitrate & bandwidth FAQ
Stream quality vs capacity
What bitrate should I use for internet radio?
128 kbps AAC is fine for talk and mobile listening. 192 kbps is a strong everyday music default. 256–320 kbps suits hi-fi or desktop listeners. Higher bitrate multiplies bandwidth for every concurrent listener.
How do I calculate radio stream bandwidth?
Multiply stream bitrate (kbps) by peak concurrent listeners, then divide by 1,000 for Mbps. Example: 192 kbps × 100 listeners ≈ 19.2 Mbps of aggregate stream capacity at peak.
Does Radiocast bill by monthly transfer?
Radiocast plans are based on concurrent listener caps, storage, and bitrate—not opaque transfer overages like some CDNs. Use this calculator to size peak listeners and stream quality, then pick a matching plan.
