Instagram Engagement Rate Calculator
Enter your followers and the likes and comments on a few recent posts. You get the engagement rate for each post, the average across them, the exact formula used, and how it compares with 2026 Instagram benchmarks.
| # | Likes | Comments | ER | Remove |
|---|---|---|---|---|
| 1 | 5.47% | |||
| 2 | 8.03% | |||
| 3 | 4.51% |

Formula used
(likes + comments) ÷ followers × 100
Worked out per post, then averaged, so one big post counts the same as one small one.
Benchmark
Instagram brand accounts, by followers: 0.35%–0.50% average (Socialinsider, 2026).
Above the band
Benchmarks are averages for brand accounts with 1K–1M followers, so treat them as a rough yardstick. Your numbers stay in your browser.
How to calculate your Instagram engagement rate
-
Pick a formula
"Followers" divides interactions by your follower count, the way most brands and benchmarks do it. "Reach" divides by the accounts that saw the post, which is fairer when only some followers see each post.
-
Add your posts
Type likes and comments for each post, or open "Paste several posts" and paste rows straight from a spreadsheet. Use 6 to 12 recent posts so one outlier does not decide the answer.
-
Decide on saves and shares
Tick the box to count saves and shares too. Leave it off when you compare with the benchmark below, which counts likes and comments only.
-
Read the average and the median
The average is the mean of each post’s rate. The median is the middle post, which a single viral Reel cannot drag up. If they are far apart, the median is the more honest number.
The Instagram engagement rate formula
By followers: (likes + comments) ÷ followers × 100. A post with 400 likes and 20 comments on an account with 10,000 followers has an engagement rate of 4.2%. This is the formula behind most published benchmarks, so use it when you want to compare.
By reach: (likes + comments) ÷ accounts reached × 100. The same post reaching 6,000 accounts has a 7% rate by reach. Reach-based rates are higher because they leave out followers who never saw the post. They are better for judging the post itself.
Averaging posts: the calculator works out each post’s rate and then averages them. Adding up all the likes and dividing once gives a different answer when reach varies a lot between posts. Per-post averaging is how Socialinsider builds its benchmarks.
What is a good engagement rate on Instagram in 2026?
Average engagement rate by followers (likes + comments), from Socialinsider's Instagram benchmarks (published 20 February 2026, updated with Q3 2026 data). The study covers 67.5 million organic posts from brand accounts with 1,000 to 1 million followers.
| Post type | 2024 | 2025 | Q3 2026 |
|---|---|---|---|
| All posts | 0.50% | 0.48% | 0.45% |
| Carousels | 0.55% | 0.55% | 0.50% |
| Reels | 0.50% | 0.52% | 0.48% |
| Images | 0.45% | 0.37% | 0.35% |
The calculator’s benchmark band (0.35%–0.50%) spans the Q3 2026 formats. These are brand accounts; personal creator accounts are not in the sample and can look quite different. For context, Socialinsider’s cross-platform report (16 January 2026) puts TikTok far higher on the same formula.
Which engagement rate should you report?
To a brand
Give the rate by followers over your last 10 to 12 posts, and say which interactions you counted. It is the number brands can compare across creators.
To judge your content
Use the rate by reach. It tells you how people who actually saw a post reacted, which is what you control.
To track growth
Pick one formula and stick with it. Mixing formulas month to month makes a flat account look like it is rising or falling.
To spot a problem
A rate by followers far below your rate by reach means most followers are not seeing your posts, not that the posts are weak.
Where to find the numbers in Instagram
- Likes and comments are under each post. Likes may be hidden from others but you can always see your own.
- Reach, saves and shares are in the post’s insights. Tap "View insights" under a post on a professional (creator or business) account.
- Followers is on your profile. Use the number on the day you check, not the day you posted, unless you track it over time.
- Many posts at once: export from your analytics tool or Meta Business Suite, then paste the columns into the calculator in the order likes, comments, saves, shares, reach.
How to raise your engagement rate
- Lead with the hook. Reels that hold attention in the first second get watched, and watched posts get liked. Our hook guide has openers that work.
- Try carousels. In the 2024–2026 benchmarks above, carousels matched or beat every other format.
- Ask for one specific action. A clear question earns comments; a useful checklist earns saves.
- Use the full 9:16 frame for Reels. See the Reels size guide for the safe zones.
Post more Reels from the videos you already have
Short.now turns your long videos into captioned 9:16 Reels, and on paid plans posts them to Instagram on a schedule you set.
Questions
Add the likes and comments on a post, divide by your follower count and multiply by 100. Do it for several posts and average the results. Some people also count saves and shares, or divide by reach instead of followers.
Socialinsider’s 2026 benchmarks put the average for brand accounts at 0.45% by followers in Q3 2026, with carousels at 0.50% and Reels at 0.48%. Anything above about 0.5% on that formula is above the brand average.
They are real engagement, so counting them is reasonable. Just say so, and switch them off when you compare with benchmarks that count likes and comments only.
By followers is better for comparing accounts, since anyone can see a follower count. By reach is better for judging your own posts, because it only counts people who saw them.
Six to twelve recent posts is a good sample. Fewer and one viral post skews the average; many more and old posts drag in stale results.
