The formulas behind the calculator
Every result uses simple arithmetic you can check by hand.
Estimated watch hours
Views × average view duration ÷ 3,600
Average view duration is in seconds. 10,000 views at a 4:30 average is 750 hours.
Views needed for a goal
Goal hours × 3,600 ÷ average view duration
Rounded up to a whole view. 4,000 hours at a 5-minute average needs 48,000 views.
Time to watch a batch
Videos × average length ÷ playback speed
Faster playback shortens the total. 20 videos of 10 minutes take about 100 minutes at 2× speed.
Watch time vs. playlist length
This calculator estimates watch time from averages, so it needs no YouTube link. To add up the exact runtime of a real playlist, use the playlist length calculator.
