Instagram Engagement Calculator

Find out if your engagement is good for an account your size. Enter a username and we work it out from the last 12 posts, or type in your own followers, likes and comments.

@

We average the likes and comments on the account's last 12 posts, leaving out ads. Private accounts cannot be checked.

How your engagement rate is worked out

Your engagement rate is the likes and comments on an average post, divided by your followers, times 100. With 12,400 followers and an average of 380 likes and 14 comments, the sum is (380 + 14) ÷ 12,400 × 100, which is 3.18%.

The likes to followers ratio uses likes on their own. It is useful if you want to compare yourself with accounts that turn comments off. Comments per 100 likes shows how much conversation your posts start.

Some people divide by reach instead of followers. Only you can see your reach, in Instagram Insights, so the follower method is the one to use when you compare your account with others.

What counts as good engagement on Instagram

The table shows engagement rates for 223 Instagram creators tracked by our sister company Sup in September 2026, split by follower count. A rate in the middle column is normal for that size. The left column is the bottom quarter of accounts and the right column is the top quarter.

FollowersLow (bottom quarter)MedianStrong (top quarter)
10,000 to 50,000under 1.69%2.97%over 6.29%
50,000 to 100,000under 1.49%2.08%over 4.30%

500,000 or moreunder 1.35%2.45%over 4.52%

Engagement rates fall as accounts grow, because a smaller share of a big audience sees each post. There is no group under 10,000 followers in this data. Small accounts usually do better than the 10,000 to 50,000 group, so aim to beat its 2.97% median.

Why engagement drops, and how to raise it

Instagram shows each post to a small group of your followers first. If they like and comment, it shows the post to more people. That is why a few quiet posts in a row can make the next ones reach fewer people too.

  • Followers who never interact. Old, inactive or bought followers still count in your follower number but never like anything, so your rate goes down. Our ghost follower checker shows how many you have.
  • Fewer Reels. Reels reach people beyond your followers, and the likes they bring also help the rest of your posts.
  • Posting when your followers are offline. Our best time to post checker finds your best slots from your own results.
  • Captions with nothing to reply to. A question, a choice between two options or a request for tips gives people a reason to comment.

Our longer guide to why Instagram engagement is low covers each cause in more detail.

Growing followers without hurting engagement

Every follower who never interacts lowers your engagement rate. If 5,000 followers give you 150 likes and comments a post, your rate is 3%. Add 5,000 followers who never interact and the same 150 interactions give you 1.5%.

That is why the kind of follower matters more than the number. Sup Growth's team engages by hand with people in your niche and area from your account, so the people who follow back are interested in what you post. You can also use our Instagram growth calculator to see when you will reach your next follower goal.

Instagram engagement: common questions

For accounts with 10,000 to 50,000 followers, the median in Sup's data is 2.97%, and the middle half of accounts sit between 1.69% and 6.29%. Bigger accounts have lower rates, with a median of about 2.1% between 50,000 and 500,000 followers. Accounts under 10,000 followers usually do better than these numbers.

Add the likes and comments on your recent posts, divide by the number of posts to get an average, then divide that average by your followers and multiply by 100. Leave out pinned posts and ads, because they get more reach than normal posts.

Yes. Enter any public username and the calculator works out the rate from their last 12 posts.

This calculator uses likes and comments because anyone can see them, which makes the rate easy to compare between accounts. Saves and shares only show in your own Insights. You can add them for a fuller picture of your own posts, but do not compare that number with rates worked out from likes and comments only.

The most common reasons are followers who never interact, posting less often, fewer Reels, posting when your followers are offline, and captions that do not invite a reply. Bought followers are the fastest way to lower your rate, because they add to your follower count without adding any likes.

If you check your own account, switch to “Enter your own numbers” and use the likes you can see. For other accounts that hide likes, the calculator counts comments only and says so.
