Two 2026 benchmark studies put Instagram’s median organic engagement rate by followers at 0.30% and 0.48%. Both figures divide interactions by follower count. The gap comes from different samples, not different maths.
Socialinsider’s Instagram benchmark reports 0.48% for 2026, down 24% year on year, based on 35 million posts from 447,613 active accounts published between January and December 2025. Rival IQ, now part of Quid, reports 0.30% as the all-industry median in its 2026 Social Media Industry Benchmark Report, drawn from 150 randomly selected companies per industry out of a database of more than 200,000.

Engagement by format
Socialinsider breaks the 2026 figure down by post type. This spread is larger than most timing or hashtag experiments will produce.
| Format | 2026 engagement rate (by followers) | Q2 2026 | Average posts per month |
|---|---|---|---|
| Carousel | 0.55% | 0.50% | 5 |
| Reel | 0.52% | 0.48% | 8 |
| Single image | 0.37% | 0.33% | 7 |
Carousels edge out reels on a per-follower basis, which surprises people who assume reels win everything. Reels usually win on reach, because they are distributed to non-followers; carousels win on interaction from the audience you already have. Those are different jobs, and the metric you pick decides which format looks better.

The formula matters more than the number
Socialinsider’s Instagram formula is explicit: “total engagement (the sum of likes and comments) of the posts published within an established timeframe divided by the total number of followers that a profile has,” times 100. Note what is not in the numerator: saves and shares.
That matters. Take a carousel with 400 likes, 60 comments, 90 saves and 40 shares on a 20,000-follower account that reached 8,000 accounts.
| Calculation | Arithmetic | Result |
|---|---|---|
| Socialinsider method (likes + comments / followers) | 460 / 20,000 | 2.30% |
| All interactions / followers | 590 / 20,000 | 2.95% |
| All interactions / reach | 590 / 8,000 | 7.38% |
If your analytics tool counts saves and the benchmark does not, you are already reading high before you compare anything. Run your own numbers through the engagement rate calculator with the same inputs the study used, then compare.
Why bigger accounts post lower rates
Follower counts accumulate and never shrink much. Reach does not accumulate. So the denominator of a per-follower rate grows faster than the numerator, and the ratio falls even when nothing about the content changed.
This is why a 1,000-follower account should not measure itself against 0.48%. At that size a single post that reaches beyond your followers can double your monthly rate, and a quiet week can halve it. The variance is bigger than the signal. Track raw reach and saves until you have enough posts for an average to mean something.
What a benchmark is for
A benchmark is a starting point for comparison against your own trend, not a target. Compare your engagement rate this quarter to your engagement rate last quarter, using an unchanged formula. That comparison controls for your niche, your country mix, your audience age and your posting cadence, none of which a published median knows anything about.
Industry is the one external cut worth making. Rival IQ reports higher education at 2.10% on Instagram against a 0.30% all-industry median, and nonprofits at 0.56%. If the category swings the number by 7x, the all-industry line is not your line.
What to do
- Write down your formula, including whether saves and shares count.
- Recalculate the last 12 months with it.
- Split by format. If carousels beat reels for you, the aggregate median does not apply to you.
- Watch the trend, not the level. A steady 0.35% is a healthier signal than a rate that bounced from 0.9% to 0.2% while you changed three things at once.
If your rate is falling while reach is flat, the content is reaching people who do not want it. That is usually a targeting or format problem, not a posting-time problem, though posting time is worth testing once the format question is settled. Format choice interacts with how many hashtags you use less than most guides claim.
Keeping the measurement consistent
Instagram’s own insights, a third-party tool and a spreadsheet will happily give you three different engagement rates for the same post because they include different interactions. BulkPublish stores the raw per-post counts it pulls back from the Instagram API, so the analytics view lets you apply one formula across every channel instead of accepting each platform’s house definition.
