Engagement rate is (reactions plus comments plus shares) divided by impressions, multiplied by 100, which mirrors how LinkedIn's own analytics measure a post.

A LinkedIn engagement rate calculator turns your reactions, comments and shares into a percentage measured against impressions, the same base LinkedIn itself uses to judge how a post performed.
LinkedIn's algorithm can push a post well beyond your direct connections if early engagement looks strong, so measuring against impressions captures that extended reach in a way that follower count never could. Two posts with identical follower counts can have wildly different impressions depending on how the algorithm chose to distribute each one.
LinkedIn tests new posts with a small initial audience before deciding how far to push them, and comments in roughly the first sixty to ninety minutes carry unusual weight in that decision. Replying quickly to early commenters, and prompting a genuine question in the post itself, both tend to extend that early engagement window and lift total impressions.
Text-first posts with a clear personal angle, a specific lesson, or a mildly contrarian take tend to outperform posts that just link out to an external article, since LinkedIn has historically deprioritized posts that send people off-platform. Native documents and short native video also tend to hold attention longer, which supports the same content-first thinking behind effective B2B content strategy.
