YouTube Shorts Retention Calculator

The calculator needs two numbers from one Short: its length and its average view duration. Every other field adds one more result.

1. Open the Short in YouTube Studio, select Analytics, and copy the length and the average view duration in seconds.
2. Add the viewed percentage and the shown in feed count to split viewers from swipes. Add engaged views for watch time.
3. Add your own typical retention or a target, then read the result and the coloured verdict.

YouTube Shorts retention is how much of a Short viewers watch before they leave. This page measures it two ways, and both come from your own YouTube Studio data.

Share of the Short Watched

The first measure is average view duration divided by the length of the Short. YouTube Help, read on October 3, 2026, defines average view duration as the average minutes watched among those who stayed to watch. It is calculated from engaged views and their watch time.

Viewed Versus Swiped Away

The second measure belongs to the Shorts Feed. YouTube Help lists two Shorts metrics on the Content tab:

• Shown in feed: the number of times your Shorts showed in the Shorts Feed.
• How many chose to view: the percentage of times viewers viewed your Shorts versus swiped away.

The two measures answer different questions. The viewed share tells you whether the opening stopped the swipe. The share watched tells you whether the rest of the Short kept people. Retention is not a revenue figure. For earnings per 1,000 views, see the Shorts RPM calculator.

1. The tool divides average view duration by the Short length and multiplies by 100.
2. It subtracts the viewed percentage from 100 to get the swiped away share.
3. It multiplies shown in feed by each share to turn the percentages into counts.
4. It multiplies engaged views by average view duration and divides by 3,600 for hours.
5. It subtracts your typical figure from the result to show the gap in percentage points.
6. It multiplies your target by the Short length to find the average view duration you would need.

Every step is plain division or multiplication on your inputs. The page holds no hidden weights and no benchmark table. You can check any line with a percentage calculator.

Example values only. A Short is 34 seconds long. Studio shows an average view duration of 26 seconds, 24,000 engaged views, 42,000 feed showings and a viewed share of 68%. The channel usually sees 70% and aims for 85%.

• Average percentage watched = 26 / 34 x 100 = 76.5%.
• Average seconds not watched = 34 - 26 = 8 seconds.
• Swiped away = 100 - 68 = 32%.
• Viewed = 42,000 x 68% = 28,560. Swiped away = 42,000 - 28,560 = 13,440.
• Views per swipe = 68 / 32 = 2.13.
• Watch time = 24,000 x 26 / 3,600 = 173.3 hours.
• Vs typical = 76.5 - 70 = +6.5 points.
• Average view needed for 85% = 85% x 34 = 28.9 seconds, or 2.9 seconds more.

This Short beat the channel's usual figure. To reach the 85% target it needs viewers to stay about 3 seconds longer. The second preset shows a 2 minute Short: 51 / 120 x 100 = 42.5%, which is 5.5 points below that channel's typical 48%.

Length of the Short

The same seconds watched give a lower percentage on a longer Short. 21 seconds is 70.0% of a 30 second Short and 35.0% of a 60 second one. Compare Shorts of similar length. YouTube Help gives the same advice for its own retention report.

Which Views Are Counted

YouTube Help says that since March 31, 2025 a Shorts view counts each time a Short starts to play or replay, with no minimum watch time. The older metric stays in Analytics under the name Engaged views. Average view duration is based on engaged views, so use engaged views for watch time.

The Opening Seconds

The viewed versus swiped away share is decided at the start of the Short. A low viewed share with a high percentage watched means the opening loses people, but those who stay like the rest.

Data Delay and Small Samples

YouTube Help notes that audience retention data typically takes 1 to 2 days to process. A Short with few views can also swing a lot from one day to the next. Wait for the numbers to settle before you judge it.

The two retention measures use different data and point to different fixes.

Long-form videos use a different report with key moments such as intros and dips. YouTube Help says a video should be at least 60 seconds long and have at least 100 views for those moments to show.

• After a Short settles. Check one Short against your typical figure to see whether a new hook or format worked.
• Before you change length. Run two Shorts of different lengths to see how the same seconds watched change the percentage.
• When you plan output. Feed the watch time and views into the Shorts to long-form funnel calculator to see what your Shorts send onward.
• When a brand asks for numbers. A retention figure from your own Studio data supports a quote from the Shorts sponsorship calculator.

• Mixing units. Enter both length and average view duration in seconds. A 1:10 Short is 70 seconds.
• Comparing Shorts of very different length. A 15 second Short and a 150 second Short do not share a fair percentage scale.
• Using views where engaged views belong. Views now count every start and replay, so watch time built on them is too high.
• Chasing a published pass mark. YouTube Help gives no target percentage for Shorts. Lists of "good" retention tiers on other sites are not from YouTube.
• Judging one Short alone. One result says little. Your typical figure across recent Shorts is the useful yardstick.
• Reading the feed split as retention. A high viewed share does not mean people watched to the end.

The calculator is exact for the numbers you enter. Its limits come from what those numbers leave out.

YouTube does not publish a good or bad retention rate for Shorts. The honest yardstick is your own channel. Work out the figure for your recent Shorts of similar length, take the average, and compare each new Short with it.

It is in YouTube Studio. Go to Content, pick the Short and select Analytics. Average view duration appears with the key metrics on the Overview or Engagement tab. Convert it to seconds before you enter it.

It is the share of feed showings where a viewer watched the Short instead of swiping past it. YouTube Help calls the metric "How many chose to view" and places it with the Shorts metrics on the Content tab.

A Short can be up to three minutes long. YouTube Help says square or vertical videos up to three minutes uploaded on or after October 15, 2024 are classed as Shorts. That is why this tool accepts lengths up to 180 seconds.

The viewed share cannot. The share watched goes above 100% only when the average view duration you enter is longer than the Short itself. The tool shows that result as it is and asks you to recheck both numbers.

Views count every time a Short starts to play or replay. Engaged views are the older Shorts view metric, kept in Analytics to show how many viewers chose to keep watching. YouTube Help says average view duration is calculated from engaged views.

Not directly. YouTube Help says Shorts ad revenue is shared from a Creator Pool based on each creator's share of engaged views. Retention is not part of that published formula, so this tool does not turn it into money.

Use enough Shorts that one outlier does not move the average much. Ten recent Shorts of similar length is a reasonable working set. That number is a practical suggestion, not a YouTube rule.

Studio keeps updating as more views arrive and as data finishes processing. YouTube Help notes that audience retention data typically takes 1 to 2 days to process. Recalculate once the Short has settled.
