Estimate total watch time accumulated by any YouTube video based on its public view count and duration. Free, no login.

This tool multiplies a video's total view count by its exact duration to produce a theoretical maximum watch time. The real figure is always lower because average view duration is typically 40–60% of total length — but the estimate still gives you a useful order-of-magnitude comparison across videos.
YouTube's monetization threshold requires 4,000 watch hours in the past 12 months channel-wide. Use this calculator to see how individual videos contribute to that goal, or to estimate how much time your audience has collectively invested in a piece of content.
Four numbers that put a video's accumulated viewing time in perspective.
Exact runtime parsed from the ISO 8601 duration the API returns, displayed in hours, minutes and seconds for easy reading.
The public view count at the time of the check, used as the multiplier in the watch time calculation.
Views multiplied by duration gives the theoretical maximum watch hours this video has generated — a useful baseline even though actual watch duration is lower.
The total expressed in whole hours for quick comparison against the 4,000-hour YouTube Partner Program threshold.
