About Watch Time Estimate Calculator

Watch hours drive algorithmic distribution and monetisation eligibility on most video platforms, while retention percentage indicates whether the content holds attention. Long videos can win on hours while losing on retention.

Formula

Watch time

Watch hours = views × average duration / 3600; retention = average duration / video length

Worked example

With the default values below, Watch Time Estimate Calculator returns Total Watch Time of 10,069.44. Change any input above and every figure here is recalculated in your browser.

  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Figures are estimates based on the inputs given. Marketing performance, platform fees and conversion behaviour vary by audience, channel and season. Use this as a planning guide, not a forecast.

Frequently Asked Questions

Which matters more, hours or retention?

Retention drives recommendation; hours drive monetisation thresholds. Both need watching.

Does making videos longer help?

Only if retention holds. Padding raises length but drops retention, which usually harms distribution.
