How engagement rate is calculated
Engagement rate compares how many people interacted with your posts to the size of your audience. This calculator uses two common formulas:
- By followers: (total engagements ÷ number of posts) ÷ followers × 100.
- By reach: total engagements ÷ total reach of those posts × 100.
By followers is useful for comparing your account with itself over time. By reach better reflects how interesting the content was to people who actually saw it.
What is a good engagement rate?
There is no universal number: it varies by network, industry, account size and how each platform distributes content. The most useful comparison is with yourself: calculate your rate monthly with the same method and watch the trend.
How to use the result
- Spot which formats and topics drive comments and saves.
- Repeat topics that start conversations and rework the ones that don’t.
- Check your consistency too: posting regularly makes months easier to compare.
