Enter the video's duration and the average view duration (in minutes and seconds) to get the average percentage viewed: (average view duration ÷ video duration) × 100. It's a single estimated average percentage from two aggregate values — it does not reproduce YouTube's full Audience Retention curve/report, which shows per-segment data across the video. If the entered average view duration exceeds the video's duration (for example, from rewatches), the result can exceed 100% and is shown as-is, without an artificial cap. It never queries YouTube and never classifies the result as "good" or "bad".
This calculation is a single estimated average percentage from two aggregate durations — it does not reproduce YouTube's full Audience Retention curve/report, which shows per-segment data across the video.
YouTube is never queried: the calculation depends solely on the two durations you enter. This percentage is never classified as "good" or "bad".
