How do I calculate engagement rate?

Add up the interactions (likes, comments, shares, saves — and clicks if you count them), divide by followers, reach or impressions, and multiply by 100.

What is a good engagement rate?

There's no official benchmark, and figures quoted online use different formulas. The useful comparison is with your own recent posts, measured the same way.

Which formula does Instagram use?

Instagram doesn't publish an engagement rate. Its insights give Interactions and Accounts engaged, so pick a formula here and stick with it.

By followers — interactions per post ÷ followers × 100. Compares accounts, but counts followers who never saw the post.
By reach — interactions ÷ accounts reached × 100. How many of the people who saw it reacted.
By impressions — interactions ÷ impressions × 100. What X and LinkedIn's own analytics show (with clicks counted).

What the platforms themselves use

X
Engagements divided by impressions. Counted: Every click on the post — reposts, replies, follows, likes, links, media, the username or profile photo, expanding the post.
LinkedIn
Interactions per impression on your post. Counted: Clicks, reactions, comments and shares.
Instagram
No engagement rate published. Insights shows Interactions and Accounts engaged (people who interacted). Counted: Likes, comments, shares, saves, replies — reported as counts, not a rate.
TikTok, YouTube, Facebook
No official engagement-rate definition published.

How to use this

What it does

Adds up a post's interactions and divides them by your followers, by the accounts the post reached and by its impressions — the three ways engagement rate is usually worked out — and shows which one X and LinkedIn use in their own analytics.

What you'll need

Likes, comments, shares and saves from the post's insights
Followers, and reach or impressions if you have them
Optionally clicks, and the number of posts if the numbers are totals

Steps

Open the post's insights in the app.
Copy the numbers in.
Compare the rates — and use the same one every time you compare posts.

Reading the result

The three numbers will differ: reach is smaller than followers for most posts, so the reach rate is higher. None is the right one; what matters is comparing like with like — the same formula, post after post.

Tips

Compare a post with your own last ten, not with someone else's account.
Reach-based rates are fairer when followers have grown fast.
Saves and shares often tell you more than likes.

What is engagement rate?

Engagement rate is the share of people who interacted with a post — liked, commented, shared, saved or clicked — as a percentage of an audience: your followers, the accounts the post reached, or the times it was seen.

There is no single official formula. X defines it as engagements divided by impressions; LinkedIn as interactions per impression. Instagram reports interactions and accounts engaged but publishes no engagement rate.

Why creators and brands use it

Follower counts say how big an account is; engagement rate says whether people care about what it posts. Brands ask for it, and it's the quickest way to see which of your posts worked.

Common mistakes

Mixing formulas. a 4% reach rate and a 2% follower rate can be the same post.
Counting your own replies. your answers to comments inflate the count.
Comparing with other niches. rates vary a lot between topics and account sizes.
