Track your 4,000 hour monetization goal
To join the YouTube Partner Program, you need: 1,000 subscribers AND 4,000 watch hours in the past 12 months (or 10M Shorts views in 90 days). Watch hours accumulate from public videos only. Use this calculator to project when you'll hit the threshold.
YouTube counts watch time from public videos viewed on and off the platform, but there are important exclusions. Deleted and private videos contribute nothing, unlisted videos do count toward watch hours, and Shorts views are tracked separately under the Shorts threshold rather than converting into watch hours. The 4,000-hour figure is a rolling 12-month window, which means the number can go down as well as up — hours earned thirteen months ago fall out of the window even as new hours accrue. Channels near the threshold should therefore watch the trend line in YouTube Studio's monetization tab, not just the current total.
Estimated views from Premieres, livestream replays, and embedded players all count toward watch time as long as the content is public. What the metric rewards is total minutes watched, so a channel with modest view counts but strong retention — long videos that people actually finish — can out-accumulate a channel with more views and worse retention.
The calculator works from four numbers you can read directly out of YouTube Studio: your current watch hours, average views per video, average view duration in minutes, and publishing cadence. Hours per video is views × duration ÷ 60; weekly watch hours is that product times videos per week; and weeks to monetization is hours remaining ÷ weekly rate. For example, a channel with 1,200 hours banked, 500 average views, 5-minute average duration, and 2 videos per week earns about 83 hours per week and crosses 4,000 hours in roughly 34 weeks.
The projection assumes a steady state, which real channels rarely have. A video that the algorithm picks up can add more hours in a weekend than a quarter of regular publishing produces, and older videos keep generating residual watch time that the simple model does not credit. Treat the calculator's date as the conservative, no-viral-hit estimate — the realistic floor for your timeline, not a prediction.
The full Partner Program gate has two subscriber paths, each with its own watch metric. The table below summarizes the standard thresholds. Note that fan-funding features have a lower bar than ad revenue in some regions, and the exact requirements YouTube enforces can vary slightly by country — check the monetization tab in YouTube Studio for the version that applies to your channel.
| Requirement path | Subscribers | Watch metric (rolling) |
|---|---|---|
| Long-form path | 1,000 | 4,000 public watch hours in 12 months |
| Shorts path | 1,000 | 10 million Shorts views in 90 days |
| Fan funding (where available) | 500 | 3 public uploads in 90 days + 3,000 watch hours or 3M Shorts views |
Because watch time is views × retention, you can grow it along either axis. Longer videos multiply every view: at the same retention percentage, a 15-minute video earns three times the watch time of a 5-minute one, and longer videos also carry more ad slots once monetized. Series and playlists encourage binge sessions, where one discovery cascades into several videos of watch time. Search-oriented evergreen content keeps accumulating views months after upload, unlike trend-chasing videos whose views decay in weeks — a portfolio of evergreen titles is the most reliable engine for a 12-month rolling window.
Cadence matters as a multiplier on everything else: two solid videos a week doubles the accumulation rate of one. But do not trade quality for quantity — a weak video that tanks average view duration drags the whole channel's suggested traffic, indirectly slowing watch-hour growth more than the extra upload helped it.
How do I check my YouTube watch hours?
Open YouTube Studio, go to the Earn/Monetization tab, and the eligibility card shows your public watch hours in the trailing 12 months alongside subscriber count. The Analytics tab breaks the same data down by video and date range.
Do Shorts views count toward the 4,000 hours?
No. Shorts views count only toward the separate Shorts path of 10 million views in 90 days. Long-form watch hours come from your regular public videos; the calculator on this page projects that long-form path.
Do deleted videos remove watch hours?
Yes. Watch time from deleted or private videos drops out of your rolling total, which can push a channel back under 4,000 hours. Unlisted videos continue to count.
Can watch hours go down over time?
Yes. The 4,000 hours are measured over a rolling 12-month window, so hours earned more than a year ago expire out of the total even if you keep publishing. Consistent output keeps the window full.
How long does it take to reach 4,000 watch hours?
It depends entirely on views, duration, and cadence — anywhere from weeks for a breakout video to over a year at two modest videos a week. Enter your channel's real numbers above and the calculator gives you a date estimate based on your current pace.
