About the Facebook Engagement Rate Calculator

Facebook engagement is normally measured against reach rather than followers, because organic reach on a Page is only ever a fraction of the people who follow it. Judging a post against your whole follower count instead measures the algorithm as much as the content.

Enter reactions, comments and shares, then choose whether to measure against reach, impressions or followers — the calculator shows the rate along with each interaction type as a share of the base, and a benchmark note that changes depending on which base you picked, because the typical ranges are nothing alike.
