Instagram Engagement Rate: The Formula, and Why "Good" Depends on Whose Formula

What is a good engagement rate on Instagram?

There is no single figure, because the answer depends on the formula. Recent benchmarks for brand accounts sit below 1 percent of followers per post: Rival IQ's 2025 report gives a median of about 0.36 percent, Socialinsider about 0.48 percent for 2025. Smaller accounts often score higher. Compare yourself with your own past posts first, using one formula, and only then with outside numbers.

The Basic Formula

Engagement rate is interactions divided by an audience, written as a percentage. Everything people argue about comes down to which interactions and which audience.
The most common version is by followers:
(likes + comments + saves + shares) ÷ followers × 100
If a post gets 250 likes, 20 comments, 20 saves and 10 shares, and the account has 10,000 followers, that's 300 interactions out of 10,000, or 3 percent. To find your account's rate, do this over a set of recent posts, say your last 10 or 20, and take the average. A median is better still, as one viral post can distort an average.
Any public profile can be estimated this way, at least roughly, but saves and shares aren't visible on other people's posts. So when you run the formula on a competitor, you're using likes and comments only, and your number won't compare directly with your own full figure.
How to calculate Instagram engagement rate by followers, reach or views, what published benchmarks measure, and why comparing your number with theirs misleads.

Three Formulas, Three Answers

The denominator changes what you're measuring.
  • By followers. This tells you how well a post moved your existing audience, and it's the easiest to compare between accounts, since follower counts are public. Its weakness is that a post seen mostly by non-followers can make it look better than it should.
  • By reach. Interactions divided by the accounts that saw the post. This tells you how good the post was at getting a reaction from those who saw it. It's usually the better measure of quality, but only you can see the reach of your own post.
  • By views. Interactions divided by total views, which counts the same person more than once. This is useful for Reels. It tends to produce lower percentages, and Instagram has been moving its reporting toward views as a primary measure.
These can give very different results for the same post. A Reel seen widely by people who don't follow you could show 40 percent by followers and 2 percent by views. Neither is wrong. They answer different questions.

Where to Find the Numbers on Your Own Account

You need a professional account (creator or business, both free to switch to) for full insights. Open a post, then tap View insights. There you'll find views, reach, likes, comments, saves and shares. Your account-level insights, found from your professional dashboard, show totals for a period you choose and split the audience between followers and non-followers.
The in-app insights don't necessarily label a single "engagement rate" figure the way these formulas do, so a simple spreadsheet still helps: one row per post, columns for reach and each interaction, plus one column for the formula you've settled on. After 20 posts you'll know which formats work for you, and that's worth more than any benchmark.

What Benchmarks Actually Tell You

Be careful with outside numbers. Most reports study brand accounts in fixed lists of industries, so a large company's posts aren't a fair yardstick for a local cafe or a new creator.
Rival IQ defines engagement rate in its benchmark report as interactions divided by total follower count. Its 2025 report covers 2024 activity and gives an all-industry Instagram median of about 0.36 percent, though the same article also cites 0.43 percent elsewhere, and its top quarter of brands reach roughly 1 percent. Socialinsider puts Instagram at about 0.48 percent for 2025, counting likes and comments only. These differences come largely from method and sample, which shows why a single "good" number is unreliable.
Also note that smaller accounts tend to show higher rates than large ones, since their audience is often closer to them. So a 3 percent rate on an account with 2,000 followers is an ordinary thing to see, and doesn't mean that account would beat a brand with 0.4 percent at 2 million followers.
A more useful test: is your own rate moving up or down over the last three months, and which formats are above your average? Those two answers tell you what to do next week.

Things That Distort the Number

Several ordinary events can move your rate without saying anything about your content.
  • A wave of new followers. More followers with the same interactions lowers the by-followers rate. Followers who don't engage do the same over time, however you got them.
  • Follower purges. Removing inactive accounts raises the rate without changing anything about your posts.
  • Bought engagement. Added likes raise the visible counts while adding nothing to what your audience actually thinks. We go into this in Do Bought Instagram Likes Affect Your Engagement Rate?
  • One viral post. It lifts an average for weeks. Use a median, or remove the outlier when you compare.
  • Giveaways. Comments rise sharply for one post and you can't read much into them.

How to Raise It, Honestly

The advice that holds up under each formula is simple. Write captions that invite a specific response, ideally a question people can answer quickly. Make things worth saving, such as lists or how-tos. Reply to comments early, because a conversation gives people a reason to come back. And post Reels that make sense from the first second, because people who don't follow you won't wait around.
For a young account, there's one more consideration. A low follower count is often what a new visitor reacts to, and so the first task is frequently to get people to stay long enough to see your content at all. Some accounts start out with INSTABOOST Instagram likes: no password is needed, delivery is gradual, and there's a 60-day free refill on what we delivered. We'd rather tell you plainly what that does: it changes what visitors see on a post, and it makes your by-followers figure less useful as a measure of what your audience thinks. So keep tracking your organic numbers separately. Other tools are on our Instagram page.

Frequently Asked Questions

How do I calculate my engagement rate on Instagram?

Add likes, comments, saves and shares on a post, divide by your followers, and multiply by 100. Repeat over your last 10 to 20 posts and use the median.

Is 1 percent a good engagement rate on Instagram?

Against published brand benchmarks, 1 percent by followers is around the top quarter reported by Rival IQ and above the typical figures of about 0.36 to 0.48 percent. For a small personal account, it may be low. Compare accounts of similar size and measure them the same way.

Do Stories count in engagement rate?

Most formulas use feed posts and Reels only, because Stories have their own metrics such as replies, sticker taps and exits. If you track Stories, keep them in a separate column.

Why did my engagement rate drop after gaining followers?

Your denominator grew faster than your interactions. That's common after a viral post, when new followers came for one thing and don't respond to the rest. Check reach too, because a falling by-followers rate can hide a post that performed well with people who saw it.
