X (Twitter) Thread Performance Calculator

The calculator needs one number per post: its view count. X shows a view count on most posts, next to the analytics icon.

1. Open your thread on X and note the view count of each post, from the first post to the last.
2. Type the counts into the box in thread order. Use spaces or new lines between them.
3. Read the completion rate, the drop after post 1 and the per-post table under the result.
4. Add the completion rate of an earlier thread to see the gap in percentage points.

Thread performance on X is how well a thread holds its views from the first post to the last post. X Help defines a thread as a series of connected posts from one person. Each post in the series has its own view count.

Three measures describe a thread:

• Completion rate: last post views divided by first post views.
• Drop-off: the percent change in views from one post to the next.
• Total thread views: the sum of every post's view count.

X Help states that view counts show the total number of times a post has been viewed, and that not all views are unique. A completion rate is a ratio of two view counts. It is not a count of people who read every post.

This page measures a thread you have already posted. It gives no score and no forecast. To compare posts that carry a tag with posts that do not, use the hashtag reach calculator.

1. The tool reads the view counts in the order you typed them.
2. It divides each count by the first count. That gives the share of first-post views at each position.
3. It divides each count by the count before it. That gives the change from post to post.
4. It marks the most negative change as the largest drop.
5. It takes the root of the completion ratio to find the average kept per step.
6. It adds every count for total thread views.

The average kept per step is a geometric mean. A thread that keeps 85% at every step for 6 steps ends at 37.7% of its first-post views.

Example values only. A 7 post thread shows these view counts: 8,400, 5,100, 4,300, 3,900, 3,600, 3,300 and 3,150.

• Completion rate = 3,150 / 8,400 x 100 = 37.5%.
• Post 1 to post 2 = 5,100 / 8,400 = 60.7% kept, a change of -39.3%.
• Post 2 to post 3 = 4,300 / 5,100 - 1 = -15.7%.
• Post 6 to post 7 = 3,150 / 3,300 - 1 = -4.5%.
• Largest drop = post 1 to post 2.
• Average kept per step = 0.375 ^ (1 / 6) = 84.9%.
• Thread views = 31,750, or 4,536 per post.

The thread loses most of its views at the first step. After post 2 the drops shrink to single digits. Against an earlier thread at 45%, this thread sits 7.5 points lower.

How X Displays Threads

X Help says a thread with 2 or 3 posts generally appears on the timeline joined by a line. A thread with 4 or more posts is truncated, with a Show this thread option. Later posts then need a tap, which is one reason they collect fewer views.

Posts Seen on Their Own

Every post in a thread is a separate post. X Help notes that a Repost or Quote of one post from a thread carries a Show this thread prompt. A post shared this way gains views that the first post never had.

Thread Length

The same step rate gives a lower completion on a longer thread. At 85% per step, a 4 post thread completes at 61.4% and a 10 post thread at 23.2%.

Posts Added Later

X Help says the author can add posts from the thread detail page after posting. A post added a day later has had less time to collect views.

Time Since Posting

View counts keep moving. Read every count in one sitting so each post has the same age.

Completion rate describes the whole thread, and the average kept per step describes one hop. The step rate lets you compare threads of different lengths. The table shows the completion that each step rate produces.

A 7 post thread at 37.5% and a 4 post thread at 61.4% both hold about 85% per step. Judge them as equal on a per-step basis. For other percent sums, the percentage calculator covers them.

After Posting a Thread

Wait until views slow down, then read every count once. The table shows where readers left.

Comparing Two Threads

Enter the completion rate of the earlier thread in the optional field. The tool reports the gap in points. For the relative gap between two rates, use the percentage difference calculator.

Finding a Weak Post

The largest drop names the post where the biggest share of views fell away. Read that post and the one before it.

Reporting to a Client

Total thread views and views per post give two plain numbers for a report. Copy report adds the method line.

1. Calling Views People

X Help says multiple views are counted when one person views a post more than once. A view count is not a reader count.

2. Adding Thread Views as Reach

Total thread views count the same reader once per post. A reader who finishes a 7 post thread adds 7 views.

3. Reading Counts at Different Times

A first post read on Monday and a last post read on Friday mix two ages. Read all counts together.

4. Typing Posts Out of Order

The tool treats the first number as post 1. A wrong order changes every result.

5. Comparing Threads of Different Lengths by Completion

A longer thread completes lower at the same step rate. Compare the average kept per step.

6. Treating One Thread as a Rule

One thread reflects one topic on one day. Measure several threads before changing how you write.

The arithmetic is exact for the counts you enter. The limits come from what a view count is.

X Help also states that embedded posts do not add to view counts and that the author's own views do count. No benchmark is built in, because X publishes no typical completion rate.

X publishes no typical completion rate, so no official benchmark exists. Compare a thread with your own earlier threads. The optional field reports the gap in percentage points.

Open the thread and read the number next to the analytics icon on each post. X Help says view counts appear on posts in the timeline and on the post details page.

The first post appears alone in many timelines. X Help says threads with 4 or more posts are truncated with a Show this thread option, so later posts often need a tap.

Yes. Each post in a thread is a separate post. A later post gains extra views when someone Reposts, Quotes or links to it directly. The tool flags a completion above 100%.

No. X Help states that not all views are unique. One person who views a post on web and then on a phone adds two views.

The X Help page on threads, read on 2026-10-03, states no maximum number of posts. It notes that text over the character limit is highlighted in each post. The How to Post page gives that limit as 280 characters.

It is the steady per-post rate that links the first count to the last count. A 7 post thread at 37.5% completion keeps an average of 84.9% per step.

Use one metric for every post. X Help calls the public number a view count. The X developer documentation defines impressions as the count of times a post appeared on a screen, also not unique.

No. It measures a thread that already has view counts. It contains no forecast, score or algorithm weight.

No. The maths runs in your browser and nothing is sent to us. Save keeps a result only in this browser.
