Show the math
Watch time is views times how long each one lasts; retention compares that to the full length:
watch hours = views × avg view duration ÷ 3600
retention = avg view duration ÷ video length × 100
YouTube's Partner Program needs 4,000 public watch hours (plus 1,000 subscribers) in the past 12 months. Only public, long-form watch time counts toward that threshold. All math runs in your browser.
What this does
A watch time calculator turns views and average view duration into total watch hours, audience retention, and your progress toward YouTube’s 4,000-hour Partner Program threshold.
How to use it
- Enter your total views.
- Enter the average view duration.
- Enter the video length.
- Read the watch hours and retention.
How it works
Retention is the average view duration as a share of length. Only public long-form watch time over the last 12 months counts toward the 4,000-hour goal.
watch hours = views × avg duration (s) ÷ 3600
Understanding your result
Watch hours and retention together show whether you are climbing toward the 4,000-hour Partner Program bar and how engaging your content is. Only public long-form watch time from the last 12 months counts, so a backlog of older or private views will not move the figure.
Example
50,000 views at 4 minutes each is about 3,333 watch hours.

Frequently asked questions
How is watch time calculated?
Total views are multiplied by the average view duration in seconds, then divided by 3,600 to convert to hours.
What is audience retention?
It is the average view duration as a share of the full video length — a higher percentage means people watch more of each video before leaving.
What counts toward the 4,000-hour goal?
YouTube counts public watch time on long-form videos over the last 12 months. Private, unlisted and (historically) Shorts watch time do not count toward that specific threshold.
