About Social Media Engagement Rate Calculator

Engagement measured against reach shows content quality; measured against followers it shows audience health. Because organic reach is only a fraction of followers, the two rates can point in opposite directions.

Formula

Engagement rate

By reach = interactions / reach; by followers = interactions / followers

Worked example

With the default values below, Social Media Engagement Rate Calculator returns Engagement Rate By Reach of 10.278%. Change any input above and every figure here is recalculated in your browser.
