Instagram engagement rate calculator

Instagram engagement formula

This calculator adds likes, comments, shares and saves. Divide that total by views, reach or followers, then multiply by 100. Use Insights for metrics that are not public, and enter 0 for interactions you cannot measure.

A Reel with 400 likes, 25 comments, 35 shares and 40 saves has 500 interactions. At 10,000 views, that is 5.00%. At 8,000 accounts reached, it is 6.25%. At 2,000 followers, it is 25.00% for that post.

Views, reach and followers measure different things

Views can include repeat viewing. Reach measures accounts reached. Followers include people who did not see the post. A percentage changes when the denominator changes, even if every interaction stays the same.

For Reels, a view-based rate can help compare videos with similar distribution. For carousels, reach can be more useful when available in Insights. A follower-based average helps compare posts relative to your account size.

Include saves consistently

A saved checklist and a shared reaction Reel may each be useful for a different goal. Keep both counts available, but compare the same interaction types. If a public competitor post does not expose shares or saves, exclude those counts from your own comparison too.

For a follower-based average across several posts, set the number of posts and enter their combined interactions. For views or reach, enter the combined denominator for that sample. Summed reach is not unique audience across the entire account: a person can appear in several posts' reach.

Does this support carousels?

Yes. Choose reach or followers and enter the carousel's interactions. You do not need a video view count.

Why is my rate different from another calculator?

Check whether it uses followers, reach or views, whether it includes saves and shares, and whether it averages individual percentages. This tool shows its denominator and uses combined counts for the sample.
