Formula 1: Engagement Rate per Post
To measure engagement for one post relative to reach:
Engagement Rate per Post (%) = (Total Engagements ÷ Total Reach) × 100Where:
- Total Engagements = sum of likes, comments, shares, clicks.
- Total Reach = unique users who viewed the post.
This highlights how compelling a single post was to the viewers it reached.
---
Formula 2: Engagement Rate per Page
To measure overall page engagement relative to followers:
Engagement Rate per Page (%) = (Total Engagements ÷ Total Followers) × 100Where:
- Total Engagements = sum of all post engagements in the time frame.
- Total Followers = current follower count.
Useful for tracking brand health and long-term performance.

Real-World Example Calculation
