How is engagement rate calculated?

KEMETORY averages the likes and comments across a profile's recent posts, adds them together, divides by the follower count and multiplies by 100. In short: (average likes + average comments) ÷ followers × 100. The number of posts sampled is shown with every result.

Is the engagement rate calculator free?

Yes. Create an account with your email, verify it with a 6-digit code, and you get 2 profile lookups every day at no cost. No credit card is required.

Why can't I analyse a personal Instagram account?

Instagram's Graph API only exposes public metrics for Business and Creator profiles. Personal accounts are not queryable by any third-party tool: that is a Meta rule, not a KEMETORY limitation. Most influencers and brands already use a Business or Creator profile.

Does checking a profile notify the account owner?

No. The tool reads public metrics through Instagram's official API. The profile owner is not notified and sees nothing.

How do I spot an influencer with fake followers?

An engagement rate far below others of the same size is the clearest warning sign, especially when the follower count is large but average comments are near zero. Compare the ratio of comments to likes as well: purchased engagement is usually heavy on likes and thin on genuine comments.

What else does KEMETORY do?

KEMETORY is a free publishing app for Instagram and Facebook: AI captions in your brand voice, automatic scheduling, carousels and Stories, analytics, and a watchlist that tracks competitor engagement and follower growth day by day.

Enter any handle

Type an Instagram Business or Creator username. KEMETORY pulls their recent posts through Instagram's official Graph API.

Read the engagement rate

You get the profile's follower count and engagement rate, calculated from the posts we sampled, shown with every result.

What is an Instagram engagement rate?

The share of an audience that actually reacts, the single most useful number in influencer marketing.

Follower count tells you how many people could see a post. Engagement rate tells you how many of them cared enough to do something about it. An account with 200,000 followers and 400 likes a post has a problem; an account with 8,000 followers and 600 likes a post has an audience that listens. That gap is invisible until you calculate it.

(Average likes + Average comments) ÷ Followers × 100

That is exactly how this tool works. KEMETORY averages the likes and comments across a profile's recent posts, divides by the follower count, and gives you the percentage. The number of posts in the sample is printed under every result, so you always know how much evidence sits behind it, a rate drawn from 30 posts is worth more than one drawn from 3.

Why comments matter more than likes. A like costs nothing. A comment costs attention. Two profiles can show the same engagement rate while one is carried by drive-by likes and the other by real conversation: so look at the comment average, not just the headline percentage, before you commit a budget.

What counts as a good engagement rate?

It depends on size. Small audiences engage harder than big ones, so judge a profile against its own tier, never against a single universal number.

Audience size	Commonly seen as healthy	What it usually means
Nano · 1k–10k	Roughly 4% and up	A tight, personal following. Highest rates on Instagram, smallest reach.
Micro · 10k–50k	Roughly 2–4%	The sweet spot most brands hunt for: real trust, meaningful reach.
Mid · 50k–250k	Roughly 1.5–3%	Reach grows, intimacy fades. Comment quality starts to matter a lot.
Macro · 250k–1M	Roughly 1–2%	Broadcast territory. Anything above 2% here is genuinely strong.
Mega · 1M+	Roughly 1% and up	Celebrity scale. Judge on reach and brand fit rather than rate alone.

These bands are rules of thumb marketers use, not laws, they move with the niche and with whatever Instagram's ranking is rewarding this season. Fashion and beauty tend to sit lower; food, fitness and travel often run hotter. The dependable move is to check three or four creators of a similar size in the same niche and see who stands out. That is what the free lookups are for.

The red flag to watch for. A large follower count paired with an engagement rate far below its tier, especially with an average comment count near zero, is the classic signature of bought followers. Real audiences argue, ask questions and tag their friends. Purchased ones sit silent.

Who uses it

Anyone about to spend money, time or trust on an Instagram audience.

Brands vetting influencers

Check a creator's engagement rate before the first email, and again before the invoice. A quiet audience is the most expensive thing you can buy.

Agencies building shortlists

Compare candidates of the same size side by side and take a defensible number into the client meeting instead of a follower count.

Creators pricing themselves

Know your own rate and where it sits against peers, then charge for the engagement you deliver rather than the followers you happen to have.

Beyond the free lookup

The calculator answers one question. The KEMETORY app answers the rest.

Frequently asked questions

Everything people ask before their first lookup.

What is a good engagement rate on Instagram?

It depends on audience size. Smaller accounts almost always engage at a higher rate than large ones, so 6% on a 5,000-follower account and 1.5% on a 500,000-follower account can both be healthy. Many marketers treat roughly 1–3% as average for mid-sized accounts, with anything above that considered strong. Use the benchmark table above and compare like with like.

How is the engagement rate calculated?

We average the likes and comments across the profile's recent posts, add them together, divide by the follower count and multiply by 100, (avg likes + avg comments) ÷ followers × 100. Every result tells you how many posts went into the sample.

Is it really free?

Yes. Register with your email, verify it with the 6-digit code, and you get 2 lookups every day at no cost. No card, no trial that quietly turns into a bill.

Why can't I analyse a personal account?

Instagram only exposes public metrics for Business and Creator profiles through its API. Personal accounts aren't queryable by any third-party tool, that's a Meta rule, not ours. Nearly every influencer worth vetting already runs a Business or Creator profile.

Will the profile owner know I checked them?

No. The tool reads public metrics through Instagram's official API. Nothing is posted, nothing is followed, and the account owner is never notified.

How do I spot fake followers?

Look for an engagement rate well below others of the same size, and check the comment average, bought engagement is heavy on likes and thin on real conversation. A million followers with a handful of comments per post is a bought audience, not an influential one.
