LUFS Streaming Loudness Penalty Calculator

Calculate how much gain reduction (loudness penalty) a streaming platform will apply to your master based on its measured integrated loudness and the platform target level.

Integrated LUFS reading from your DAW or loudness meter (e.g., Youlean, iZotope).
Target integrated loudness for the selected platform.

📖What is it?

Streaming platforms apply loudness normalization to level-match all tracks for consistent listening experience. LUFS (Loudness Units relative to Full Scale) is the measurement standard (ITU-R BS.1770). If your track is louder than the platform target, it gets turned down (penalized). If quieter, it plays at a lower level than competitors � no gain is added on most platforms.

🎯How to use

Measure your master's integrated loudness using a LUFS meter in your DAW. Enter the reading and select the target platform. If a penalty is shown, your track will be turned down by that amount � all that extra loudness squashing in mastering was wasted. If headroom is shown, your track may sound quieter than other tracks on that platform.

💡Example scenario

An EDM producer masters to -9 LUFS, targeting Spotify (-14 LUFS target). Penalty = -5 dB. All the dynamic range sacrificed during mastering is wasted � the track plays back at -14 LUFS just like a master at -14 LUFS. Moral: target platform LUFS during mastering for best dynamic range and true peak headroom.

🏆Pro tip

Master to -14 LUFS integrated (-1 dBTP true peak) for Spotify/YouTube/Amazon. For Apple Music (-16 LUFS), you can afford slightly more dynamics. Monitor with Youlean Loudness Meter 2 (free) or iZotope Insight. The "loudness war" is over on streaming � louder masters sound worse, not better, because of normalization.
