Instagram engagement rate calculator
Put in your followers and what an average post gets. The number comes straight back, with the context that makes it mean something.
How it is worked out
Engagement rate by followers is the version almost everyone quotes, and it is the one above:
(average likes + average comments) ÷ followers × 100
Take the numbers from your last nine to twelve posts and ignore anything that went unusually well or unusually badly. One viral post pulls the average somewhere your account does not actually live, and the point of the number is to describe the normal week.
What counts as good
It depends almost entirely on how many followers you have, and the direction is the opposite of what people expect: the bigger the account, the lower the rate. A 3% rate is unremarkable at 2,000 followers and excellent at 200,000. These are the ranges people usually see, and the calculator compares you against the row that matches your size.
| Followers | Typical engagement rate |
|---|---|
| Under 1,000 | 5% – 8% |
| 1,000 – 10,000 | 2.5% – 5% |
| 10,000 – 100,000 | 1.5% – 3% |
| 100,000 – 1M | 1% – 2% |
| Over 1M | 0.7% – 1.5% |
Treat these as rules of thumb, not a standard. Published benchmarks disagree with each other by a lot, they move year to year, and they differ by niche: a small cooking account and a small crypto account do not behave the same way. The useful comparison is against your own number last month.
Why the rate falls as you grow
Two reasons, and neither is your fault. Early followers are people who chose you on purpose, and they interact. As an account grows it collects passive followers, accounts that follow thousands, and people who scroll past without tapping. Meanwhile the feed only shows any given post to a fraction of your followers. A falling rate on a growing account is normal; a falling rate while the follower count is flat is the one worth looking at.
The number that quietly ruins this metric
Bought followers. They inflate the denominator and never touch the numerator, so the engagement rate drops immediately and keeps dropping. If your rate is far below the row for your size and you did not expect it, that is usually the reason, whether or not the follows were bought on purpose: giveaway spikes and follow-for-follow rounds do the same thing.
Where to look next
The number on its own rarely settles anything. The full audit puts it next to cadence and format, the audience check says whether a low rate is a follower problem, and the reach comparison says whether it has fallen recently or has always been here.
Questions
Should I count saves and shares?
If you have them, yes, and the result will be higher than the figure everyone else quotes. Saves and shares are only visible to the account owner, so no external tool or benchmark includes them. Use likes and comments when you want to compare yourself with anyone else, and the fuller number when you are comparing yourself with yourself.
Does it work for reels?
The formula does, but reels are usually measured against views rather than followers, because they are pushed to people who do not follow you. Reach-based rates look very different and are not comparable to the number above.
My rate is above the top of the range. Is that a mistake?
Not necessarily. Small, tight communities genuinely run high, and so does an account whose recent posts happened to land. Recheck it over a longer stretch of posts before you take the credit.
Do you store what I type?
No. The calculation happens in the page. There is no request to a server, so there is nothing to store.
