What this does

Enter views, average view duration, and video length, and we return total watch hours plus the average percentage of the video actually watched, the retention number that feeds recommendations.

A table shows how many views at this average duration, or how many videos like it, it would take to bank 4,000 watch hours.

Use cases
  1. 01Turn an average view duration figure into a total hours number you can compare to the monetization bar.
  2. 02See the percentage-watched figure that actually drives recommendations, not just raw views.
  3. 03Estimate how many similar videos it would take to reach a watch-hour goal.
FAQ

Questions, answered.

Is this the same as the Watch Hours Tracker?

No. This calculates watch time for one video from views and duration. The tracker projects a date to reach 4,000 hours from your current pace across the channel.

Do I need an account?

No.

What is percentage viewed actually used for?

It is one of the signals YouTube's recommendation system weighs. A higher percentage watched generally reads as a stronger match between video and viewer.
