Engagement Rate Calculator (by Followers, Reach, and Impressions)

Add up likes, comments, shares, and saves and divide by followers, reach, or impressions to get the three common engagement rates, averaged over as many posts as your totals cover.

Engagement Rate Calculator (by Followers, Reach, and Impressions): Interactions are added up and divided by the audience: 900 likes, 60 comments, 30 shares, and 10 saves make 1,000 interactions; on 20,000 followers that is 5%, on a reach of 12,000 it is 8.33%, and on 15,000 impressions 6.67%. With several posts, the follower rate is averaged per post. Runs 100% locally in your browser with zero server file uploads.

Engagement rate is interactions, likes, comments, shares, and saves, divided by an audience. By followers is the most common and lets you compare accounts; by reach and by impressions measure how the people who saw the post responded, which is fairer for posts that travelled beyond your followers. Rates fall as accounts grow and differ by platform, so compare like with like.

Small and large accounts

Engagement by followers usually falls as an account grows, because a smaller share of followers sees each post; reach-based rates are steadier.

Percentages

To compare growth from one month to the next, the percentage calculator works out the change.

How to use it

  1. Enter the interactions, from one post or a period.
  2. Enter followers, and reach or impressions if you have them, and the number of posts.
  3. Compare the three rates.

Frequently asked questions

Which rate should I use?

By followers to compare accounts with each other, and by reach to judge a post's content, since it counts only the people who saw it.

What is a good engagement rate?

It varies with platform, audience size, and industry, and published benchmarks disagree; compare against your own past posts and similar accounts.

Should I count views?

Video views are usually not counted as interactions; they are closer to impressions.
