Frequently Asked Questions
At 128 Kbps MP3, each minute of music uses approximately 1MB. A 3-minute song = ~3MB. At 320 Kbps, a 3-minute song = ~7.5MB. FLAC (lossless) files can be 20–50MB per song. Our calculator handles all bitrates.
At 128 Kbps: approximately 333 songs (3-minute average). At 256 Kbps: approximately 166 songs. At 320 Kbps: approximately 133 songs. FLAC at ~1000 Kbps: approximately 40–50 songs per GB.
Storage (MB) = Number of Songs × Average Duration (minutes) × Bitrate (Kbps) ÷ 8 ÷ 1000. Our MP3 storage calculator simplifies this with instant results for any combination.
256 Kbps AAC or 320 Kbps MP3 provides excellent quality indistinguishable from lossless for most listeners. FLAC offers true lossless quality but at 3–5× larger file sizes.
Streamed music doesn’t use permanent storage, but temporary cache may accumulate (typically cleared automatically). Downloaded offline songs for apps like Spotify or Apple Music do use permanent storage.
Spotify’s “High” quality downloads are ~160 Kbps Ogg Vorbis. At this rate, 1000 songs × 3.5 minutes average ≈ 3.5GB. “Very High” quality (320 Kbps) doubles this to approximately 7GB.
AAC (Advanced Audio Coding) at 256 Kbps offers the best balance of quality and storage efficiency. Opus format is even more efficient at lower bitrates while maintaining good perceptual quality.
