Engagement rate is the first number a brand looks at and the number most small accounts worry about. The trouble is that “good” depends entirely on how big the account is. A 3% rate is ordinary on a 4,000-follower account and excellent on a 400,000 one. This post gives you the formula, real benchmarks by follower count, and what to do if your rate is below the line.
How to calculate Instagram engagement rate
The standard formula is likes plus comments, divided by followers, multiplied by 100. Do it per post and average the last 12 posts, and take the median as well, because one giveaway or one viral Reel can double the average while a typical post is unchanged.
There is no good engagement rate, only a good rate for the size of the account. Compare within the tier and against your own last quarter.
Some tools use likes only. Some divide by reach instead of followers. Reach is only visible to the account owner, so any public tool claiming to use it is estimating. Followers is the number everyone can see, and it is the number a fee is negotiated against, so it is the one to use when comparing accounts.
If you would rather not do the maths, our sister company Sup publishes a free Instagram engagement rate calculator that pulls the last 12 posts of any public handle live, shows the rate post by post, and places it against accounts of the same size. No sign-up. It also has a manual calculator lower down the page for when you only have a screenshot or a media kit.
Engagement rate benchmarks by follower count (2026)
These figures come from the creators Sup tracks in its public directory, 223 accounts at the last data refresh, grouped by follower tier. They are computed from the data, not typed in from a report, and they update when the directory updates. One caution: the directory is built from creators that brands actually book, so these medians run a little higher than a random slice of Instagram would.
| Followers | Low (bottom quarter) | Median | Strong (top quarter) |
|---|---|---|---|
| 10k to 50k | under 1.69% | 2.97% | over 6.29% |
| 50k to 100k | under 1.49% | 2.08% | over 4.30% |
| 100k to 500k | under 1.37% | 2.09% | over 3.88% |
| 500k and up | under 1.35% | 2.45% | over 4.52% |
The directory has no creators under 10,000 followers, so there is no tier for them. Most guides put a healthy rate for very small accounts somewhere between 4% and 8%, and that matches what we see on the business accounts we grow: a local account with 2,000 real followers often runs at 5% or more, because most of those followers know the business.
Want followers who become customers?
Sup Growth’s team grows Instagram accounts by 300 to 800 real, local followers a month. No bots. A person does the work from your account and sends every new follower a welcome DM.
Why the rate falls as an account grows
A small account is followed by people who know the creator. A large one is followed by people who saw one post. The second group likes less, comments less and drifts away faster, so the rate falls even when the content gets better. That is why comparing your rate with a global average is pointless. Compare it with accounts of the same size, and compare it with your own rate three months ago.
What pulls an engagement rate down
Bought followers. They sit in the denominator and never like anything. An account that bought 5,000 followers two years ago is still paying for it in the rate today. A fake follower check tells you whether this is the problem.
Posting into silence. Accounts that post once a month start cold every time. Instagram shows a post to a small group first and widens the audience if that group reacts. A dormant audience does not react.
The wrong followers. Followers won through follow-for-follow, giveaways or a viral post outside your niche do not care about your normal content. This is the most common problem on business accounts and the hardest to see, because the follower count looks healthy.
Hidden likes and old posts. A creator who hides like counts will show a lower rate on any public tool, because only comments can be counted. And a post from this morning has not finished collecting likes yet, so a very active account will always have one or two unfinished posts pulling the average down a little.
How to raise it
Reply to every comment in the first hour. Instagram counts a reply as engagement, and a conversation under a post keeps it in feeds longer. Post Reels and carousels rather than single images: a carousel of ten photos collects more saves and comments than one image, and Reels reach people who do not follow you yet.
Ask a question in the caption, and ask it early, before the “more” fold. Post when your followers are online, which your insights show under audience activity. And grow with people who chose you. The single biggest lift we see on client accounts comes from replacing bought or random followers with real, local ones, because every one of those people is a potential customer who actually looks at the feed. That is the work Sup Growth’s team does by hand.

Frequently asked questions
Is 2% a good engagement rate on Instagram?
For an account over 100,000 followers, yes, it sits near the median. For an account under 10,000 it is low, and a sign that many followers are not really there.
Should I use likes only or likes plus comments?
Likes plus comments, because comments are much harder to buy than likes. If two accounts show the same rate but one has ten times the comments, that one has the real audience.
How many posts should I average?
Twelve is the common standard and enough to smooth out one odd post. Skip giveaways when you calculate by hand; they inflate the number.
Does engagement rate include Reel views?
No. Views are a separate measure with its own benchmarks. Sup also publishes a free average views calculator for that.
