Instagram engagement rate calculator.
Enter your numbers and get your real percentage, compared against what is typical for accounts your size. No signup, no connecting your profile.
Your numbers
Use the average of your last 8 to 10 posts, not your best one. The average is what a brand looks at.
Your engagement rate
What counts as normal, by account size.
| Size | Typical range |
|---|---|
| Nano · 1K – 10K | 4% – 6% |
| Micro · 10K – 100K | 2% – 5% |
| Mid · 100K – 500K | 1.5% – 3% |
| Macro · 500K – 1M | 1% – 2.5% |
| Mega · 1M+ | 0.5% – 2% |
These figures are industry references, not law. They vary by source, niche and format: reels perform well above static posts, and accounts under a thousand followers usually sit above the nano range.
What you are actually calculating.
The formula is simple: add every interaction on a post — likes, comments, and saves and shares if you have them — and divide by your follower count. Multiply by a hundred and that is your percentage.
There is a more accurate version that divides by reach instead of followers, because it measures the reaction of people who actually saw the post rather than people who could have. The catch is that reach only appears in your own analytics, so nobody can calculate it from outside. That is why the follower-based formula is the one brands use to evaluate you: it is the only one they can verify without asking for access.
Here is the uncomfortable consequence: engagement rate is a fraction, and followers sit in the denominator. Every follower who does not interact pushes it down. Which is why an account with two thousand active followers is worth more in a negotiation than one with twenty thousand silent ones.
Why buying followers lowers this number.
With 2,000 followers and 200 likes, your rate is 10%. Add 8,000 followers and keep getting 200 likes, and it drops to 2%. The big number impresses at a glance, but any brand looks at exactly this ratio and sees it worse than before. This is not an argument against buying followers: it is an argument for choosing the right amount and pairing it with consistent engagement.
We go through it in the article on what Instagram does and does not do when you buy followers.
Frequently asked questions.
It depends on account size. Accounts between 1,000 and 10,000 followers typically sit between 4% and 6%; between 100,000 and 500,000 it falls to 1.5%–3%; above a million it rarely exceeds 2%. The bigger the account, the lower the percentage, and that is normal.
Because followers sit in the denominator of the formula. As you grow you pick up people with less real interest in each post, and the percentage dilutes even as your absolute likes rise.
If you have them, yes: they reflect a post real value better than a like does. The fields are optional because they only appear in your own analytics and many people do not know them.
The formula is the same, but the reference ranges are not. Reels tend to perform well above static posts, so compare reels with reels and photos with photos.
No. It asks for no access, no password and no username. The whole calculation happens in your browser with the numbers you type in.
Yes, mathematically. Any follower who does not interact raises the denominator without raising the numerator. That is why choosing the right amount relative to the engagement you already get matters.
