What is the Engagement Rate Calculator?
Engagement rate shows how actively your audience interacts with your posts — and it is what brands look at before they sponsor you.
Add up likes, comments, shares and saves across recent posts to get your engagement rate by followers, and by reach if you know it.
How to use the Engagement Rate Calculator
- Enter your followers and how many posts you counted.
- Enter total likes, comments and shares & saves for those posts.
- Optionally add your average reach per post.
Understanding your results
- Engagement rate by followers
- Interactions per post ÷ followers × 100.
- Engagement rate by reach
- Interactions per post ÷ reach × 100 — fairer when only part of your audience sees each post.
