Social Media Engagement Calculator

Combine likes, comments, shares and saves into one engagement rate against reach.

About Social Media Engagement Calculator

The engagement rate is the share of accounts reached that likes, comments, shares and saves combined represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where higher is better.

Formula

Engagement Rate = Likes, comments, shares and saves combined ÷ Accounts reached × 100
