Use a free engagement rate calculator that works out your rate from likes, comments and follower or reach numbers in the browser. Enter the figures and it returns the engagement percentage. It runs with no account and nothing is uploaded.
Engagement rate expresses how much your audience interacts with a post relative to its size, rather than just the raw like count. Comparing rate rather than totals lets you judge posts and accounts of different sizes fairly. A calculator does the division for you so you get a clean percentage instead of doing the math by hand.
The tool computes the rate locally from the numbers you enter, so your figures are never sent anywhere. You put in the interactions and the follower or reach count, read the percentage, and can rerun it for any post with no sign-up and no limit.
It uses your interactions such as likes and comments together with your follower or reach count.
No. The calculation runs in your browser, so nothing is sent to a server.
