# How to Calculate Instagram Engagement Rate

Instagram engagement rate by followers is a post's likes plus comments, divided by the account's followers, times 100; for your own account you can divide by reach instead, using the interactions in your Insights.

**Instagram engagement rate by followers is a post’s likes plus comments, divided by the account’s followers, times 100; for your own account you can divide by reach instead, using the interactions in your Insights.** A post with 450 likes and 50 comments on an account with 20,000 followers has a 2.5% rate. Socialinsider’s benchmarks put the brand average around 0.45% in Q3 2026, so creators and brands land very differently.

Instagram doesn’t show an engagement rate anywhere in the app, so you calculate it. This guide gives the formulas, a worked example, benchmarks, and the mistakes that skew it. Where your own numbers live is covered in [how to see Instagram Insights](/blog/instagram-analytics/see-instagram-insights/). Two related numbers are [who shared or reposted your post](/blog/instagram-analytics/who-shared-your-post/) and [the best time to post on Instagram](/blog/instagram-analytics/best-time-to-post/).

## What Is the Instagram Engagement Rate Formula?

**There are two standard formulas: by followers, which works for any public account, and by reach, which only works for your own account.**

| Formula | Calculation | Use it for |
| --- | --- | --- |
| By followers | (likes + comments) ÷ followers × 100 | Comparing any public accounts |
| By reach | interactions ÷ accounts reached × 100 | Your own posts, from Insights |

The by-followers version uses only public numbers, which is why benchmark reports and influencer research rely on it. Saves and shares are only visible to the account owner.

## How Do You Calculate It for One Post?

**Add the likes and comments, divide by the follower count, and multiply by 100.** Listed below are the 4 steps.

1.  **Read** the counts: 450 likes, 50 comments.
2.  **Add** them: 500 interactions.
3.  **Divide** by followers: 500 ÷ 20,000 = 0.025.
4.  **Multiply** by 100: a 2.5% engagement rate.

## How Do You Calculate It for a Whole Account?

**Calculate the rate for each of the last 10 to 20 posts and take the median.** A single viral post can push an average far above what the account normally gets. Leave out posts from the last day or two, whose numbers are still growing.

## What Is a Good Engagement Rate on Instagram?

**For brand accounts, Socialinsider reports an average engagement rate of 0.45% in Q3 2026, with carousels at 0.50%, reels at 0.48% and images at 0.35%** ([Socialinsider](https://www.socialinsider.io/social-media-benchmarks/instagram)). The same source reports a year-on-year fall of about 24% across 2025. Smaller creators often score well above brand averages, so compare like with like: similar size, similar niche.

| Format (Q3 2026, brands) | Average engagement rate |
| --- | --- |
| Carousels | 0.50% |
| Reels | 0.48% |
| Images | 0.35% |
| All posts | 0.45% |

## What Mistakes Skew Engagement Rate?

**The most common mistakes are averaging instead of using the median, mixing formulas, and counting posts with hidden likes.** Listed below are the 4 to avoid.

-   **Averages** that let one viral post dominate.
-   **Mixing** by-followers and by-reach rates in one comparison.
-   **Hidden like counts**, where the owner has turned off like and view counts; leave those posts out.
-   **Bought followers**, which make the rate look low; generic comments are another warning sign, covered in [how to vet Instagram influencers with data](/blog/instagram-scraping/vet-influencers/).

## How Do You Calculate Engagement Rate for Any Public Account?

**For accounts you don’t own, use public counts across their recent posts.** apidojo’s [Instagram Scraper](https://apify.com/apidojo/instagram-scraper) on Apify returns each post’s `likeCount`, `commentCount`, the owner’s `followerCount`, and an `isLikeAndViewCountsDisabled` flag for posts with hidden counts (Apify).

```
from statistics import median
from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("apidojo/instagram-scraper").call(run_input={
    "startUrls": ["https://www.instagram.com/creator/"],
    "maxItems": 20,
})

rates = []
for p in client.dataset(run.default_dataset_id).iterate_items():
    if p.get("isLikeAndViewCountsDisabled"):
        continue
    followers = p["owner"].get("followerCount") or 0
    if followers:
        rates.append(((p.get("likeCount") or 0) + (p.get("commentCount") or 0)) / followers * 100)

print(f"Median engagement rate: {median(rates):.2f}%")
```

It costs $0.50 per 1,000 posts, and each profile should return at least 10 posts. Turning one account’s rate into a benchmark is covered in [how to track competitors on Instagram](/blog/instagram-scraping/track-competitors/). The TikTok formula and benchmarks are in [how to calculate TikTok engagement rate](/blog/tiktok-analytics/engagement-rate/).

## Questions people ask

### Does Instagram show engagement rate?

No, Insights shows interactions and reach, not a rate; calculate it yourself.

### Should saves and shares count?

Include them for your own posts, where Insights shows them; for other accounts only likes and comments are public.

### Is a high engagement rate always good?

Not always; check that comments are real and specific, not generic or repeated.

### What's a good engagement rate for influencers?

Compare creators of similar size in the same niche; see [how to find Instagram influencers in your niche](/blog/instagram-influencers/find-instagram-influencers/).
