The Engagement Rate formula
Engagement Rate = (Likes + Comments) ÷ Followers × 100
The standard, platform-agnostic engagement rate formula — total engagement on a post divided by the audience size it reached.
Example
A post got 4,200 likes and 180 comments from a 50,000-follower account.
((4,200 + 180) ÷ 50,000) × 100 = 8.76% engagement rate
