Instagram engagement rate study: what 550 real accounts show
Every engagement benchmark you can find quotes a different number, from 0.3% to 3.5%, because each one measures a different population with a different formula. This page adds a number you can trace: the engagement rate of 550 real, public Instagram accounts that people ran through our free checkers between May and September 2026, computed the same way for every account and broken down by follower count.
It is not a random sample of Instagram, and the section on method says exactly how it was built and what that skews. It is a real one, refreshed each quarter, and every figure below comes straight from the rows.
The short answer
Across the 550 accounts the median engagement rate is 5.4% of followers per post, but that headline hides the size effect. Accounts under 1,000 followers run a median 12.0%; 1,000 to 5,000 runs 3.8%; 5,000 to 10,000 runs 1.4%; 10,000 to 50,000 runs 1.8%; and everything above 50,000 sits between 1.4% and 2.6%. Almost one account in four, 23%, is under 1%.
Comments fall away faster than likes as accounts grow: under 5,000 followers there are 6.5 to 7.3 comments for every 100 likes, above 100,000 there are 1 to 3. A large account with a small-account comment ratio is the shape to check for a bought audience.
How the sample was built, and what it is not
Between 11 May and 21 September 2026, people ran 765 different public Instagram handles through our free tools: the engagement rate checker, the fake follower checker, the follower count checker, the account audit and the growth analysis on our homepage. Each check reads the account's public profile and its most recent posts, three for the quick checks and up to twelve for the deeper ones, and records followers, average likes, average comments and the number of posts read. Nothing is estimated where data is missing.
Engagement rate here is likes plus comments, divided by followers, times 100, averaged across the posts read (three on 378 of the 550 accounts, twelve on 94). That is the per-post formula most creators and brands use and the one our checker shows, and it is why these figures are higher than benchmarks that divide a single post's engagement by the whole follower base or that measure business pages only.
215 of the 765 handles, 28%, had no public posts to read, either private, empty or brand-new, and are excluded. The 550 that remain are the study. A handle checked more than once counts once, on its latest read.
What the sample is not: random. People check the accounts they are curious about, which means their own, a competitor's, a creator they might hire or an account that looks suspicious. Small accounts are over-represented, with 227 of the 550 under 1,000 followers, and the bands above 50,000 hold 46 accounts between them, so treat those rows as indicative. Every figure is a median unless it says otherwise, because engagement is heavily skewed and an average would be pulled around by a handful of accounts.
Engagement rate by follower count
The table gives, for each band, how many accounts fell in it, the median engagement rate, the middle half of the band (the 25th to 75th percentile), and the median likes and comments per post. The middle half is the honest range: half of the accounts in the band sit inside it.

What the bands say
Under 1,000 followers: 12.0% is normal, not remarkable. A small account is followed by people who know the owner, and they like what they see. This is why a nano account quoting a 15% rate to a brand is quoting the shape of its size, not a special audience. The middle half runs from 5.2% to 31.0%, the widest spread of any band.
1,000 to 5,000: the rate falls by two thirds. Median 3.8%, middle half 1.0% to 11.0%. This is the band where an account first gains followers who have never met the owner, and where the difference between an audience that was earned and one that was bought starts to show in the numbers.
5,000 to 50,000: the floor. Median 1.4% at 5,000 to 10,000 and 1.8% at 10,000 to 50,000, with the lower quartile at 0.2% to 0.5%. A quarter of accounts in these bands are, in effect, posting to nobody.
Above 50,000: it stops falling. 1.4%, 2.6% and 1.6% across the three large bands, on 46 accounts, so read them as indicative. What does keep falling is the comment ratio, below.
Almost one in four accounts is under 1%. 125 of the 550, 23%, engage under 1% of their followers per post; 61% engage at 3% or above. The under-1% group is not a size band, it is a condition: an audience that does not respond, whatever its size.
Comments per 100 likes: the ratio that falls with size
Likes are one tap and comments are a sentence, so comments are the more expensive signal and the one bought engagement rarely fakes well. Per 100 likes, the median account under 1,000 followers gets 7.3 comments, 1,000 to 5,000 gets 6.5, 5,000 to 10,000 gets 7.9, 10,000 to 50,000 gets 3.6, 50,000 to 100,000 gets 5.7, 100,000 to a million gets 3.1, and above a million gets 1.0.
The shape is the useful part. Comment ratios sit at 6 to 8 per 100 likes on accounts whose followers know them, and fall to 1 to 4 once the audience is mostly strangers. An account of 200,000 followers running 7 comments per 100 likes is either a genuine community or a comment pod; an account of 3,000 running 1 per 100 has an audience that is scrolling past. The fake follower checker reads the same two numbers and reports the comment share of engagement as one of its signals for exactly this reason.
How this compares with the published benchmarks
Rival IQ's 2026 benchmark puts the median at about 0.30% per post, Socialinsider's at 0.48%, Statista's global influencer average at 1.59% and Hootsuite's cross-industry figure at 3.5%. None of them is wrong; they measure different things. Rival IQ and Socialinsider measure brand and business pages, which are large and post often, and both divide a single post's engagement by the full follower count. Hootsuite's figure averages across industries and platforms.
This study measures the accounts real people wanted checked, which skews small and personal, and it averages across the posts read rather than judging one post. Read it beside the others rather than instead of them: if you run a brand page with 40,000 followers, the 10,000 to 50,000 row here (median 1.8%, lower quartile 0.5%) and Rival IQ's 0.3% bracket the range you should expect. If you run a personal account with 2,000 followers, the 1,000 to 5,000 row is the only benchmark on this list built from accounts like yours.
For the question most people are actually asking, whether a specific account's rate is good for its size, the engagement rate checker reads the account and puts it against the band above in one step.
What moves the rate
Who the followers are moves it more than what you post. Two accounts can post the same reel and get a 6% rate and a 0.6% rate, and the difference is almost always the audience: one was earned from people interested in the topic, the other was bought, won in a giveaway or collected by a follow-for-follow spree. A bought audience does not come back; a dormant one is the same at the reading end.
Growing with real followers keeps the rate up. An Instagram growth service that reaches people in your niche from your own account adds followers who chose you, which is why the rate holds while the count rises. In a 150-account sample of client campaigns that had run at least 90 days, measured to 19 September 2026, the median account added 302 net followers a month, the middle half between 249 and 577, and all 150 finished larger than they started.
Cleaning ghost followers helps the percentage, not the reach. Removing followers who never engage lifts the rate arithmetically and does nothing for distribution, since Instagram ranks each post on the reaction of the people it shows it to first. The fake follower statistics page covers what a purge does and does not change.

Common questions
Is a 5% engagement rate on Instagram good?
It depends on size. In this 550-account sample 5% is below the median for accounts under 1,000 followers (12.0%), above the median for 1,000 to 5,000 (3.8%) and well above it for every band over 5,000, where the median runs 1.4% to 2.6%.
Why is your median so much higher than Rival IQ's 0.3%?
Different population and different formula. Rival IQ measures brand and business pages and divides one post's engagement by all followers. This sample is the accounts people asked us to check, which skews small and personal, and averages across the posts read. Read the two side by side; neither replaces the other.
How was engagement rate calculated?
Likes plus comments on each of the most recent public posts, three for the quick checks and up to twelve for the deeper ones, divided by followers at the time of the check, times 100, then averaged across those posts. Accounts with no public posts are excluded; nothing is estimated to fill a gap.
Can I check where my own account sits?
Yes. The engagement rate checker reads any public account and shows its rate against the band for its size, free and without a login.
