What Is a Good Engagement Rate? How to Calculate It on Instagram, TikTok and YouTube
There is no single number that counts as a good engagement rate, because the answer depends on what you divide by. Rival IQ’s 2026 benchmark, published by Quid, puts median engagement at 2.01% on TikTok, 0.30% on Instagram and 0.21% on YouTube, calculated by dividing total interactions by follower count. A tool that divides by reach or views will give the same post a very different figure. So a good rate is one that beats your own recent average and holds up against similar accounts measured with the same formula.
The rest of this guide covers how engagement rate is calculated, how Instagram, TikTok and YouTube each handle it, and how to judge your result without comparing numbers that were never comparable.
What engagement rate measures
Engagement rate is the share of an audience that did something with a piece of content. The basic form is interactions divided by audience size, multiplied by 100.
“Interactions” and “audience size” both vary. On Instagram, content interactions include likes, comments, saves, shares and replies. Quid’s benchmark uses a wider definition that also takes in reposts, reactions and video interactions. Audience size might be followers, reach, impressions or views.
Engagement rate also has limits. It does not measure sales, enquiries or whether anyone watched a video to the end. It is a ratio of visible reactions to an audience, and it only helps if you pair it with the outcome you care about.
Four ways to calculate it
Social analytics firms list several common versions: engagement rate by followers, by reach and by impressions, which includes repeat views by the same person. Video platforms add a fourth, engagement rate by views. There is no universal formula.
Here is how far apart they can land. Say an Instagram post earns 120 likes, 15 comments, 20 saves and 10 shares, which is 165 interactions. The account has 10,000 followers, and Instagram reports that the post reached 3,300 accounts.
- By followers: 165 ÷ 10,000 × 100 = 1.65%
- By reach: 165 ÷ 3,300 × 100 = 5.00%
This is a hypothetical example, but the gap is real. If one report quotes the first number and another quotes the second, neither is wrong, but they cannot be compared.
How to calculate engagement rate on Instagram
Instagram’s own analytics help here, with one condition: Insights are free but available only for business or creator accounts. Two terms are easy to confuse. Accounts reached counts unique accounts that saw your content at least once. Accounts engaged counts unique accounts that interacted with it. Someone who likes, comments and saves counts as one engaged account but three interactions, so check which one a calculation uses.
- Choose your last 10 posts, keeping Reels separate from carousels and single images.
- Add up the interactions on each post: likes, comments, saves and shares.
- Divide by reach if you can see it in Insights, or by followers if you cannot.
- Multiply by 100, then take the middle value across the 10 posts rather than the average, so one standout post does not distort the result.
On someone else’s account you will usually see only public likes and comments, not saves or shares. A rate built from those will run lower than the same account’s true figure, so use it to compare accounts you measured the same way, not as a verdict.
How to calculate engagement rate on TikTok
A TikTok video is shown to people who do not follow you, so followers make a poor denominator. Take a video with 40,000 views and 1,200 combined likes, comments and shares. By views that is 3.0%. Divide the same 1,200 by 8,000 followers and it becomes 15%, which says more about how far the video travelled than about how much viewers liked it.
TikTok’s analytics report likes, comments, shares and views as separate figures. TikTok’s own newsroom tutorial describes an overview of total likes, comments and shares, with per-video views and average watch time. Analytics tools usually define the rate on views: Iconosquare, for example, divides likes, comments and shares by views. Whether you add saves is your choice, but state it, because it changes the result.
Quid’s benchmark does the opposite. It divides by follower count even for TikTok. That is one reason a TikTok benchmark you read elsewhere may look nothing like 2.01%.
Average watch time deserves equal attention on TikTok. A video with plenty of likes but short average watch time is telling you something the rate cannot.
How to calculate engagement rate on YouTube
YouTube has the clearest published definition of the three. In Google’s advertising API, a channel’s lifetime engagement rate is total engagement divided by total views. Likes, shares and comments make up the engagement.
For a long-form video with 5,000 views, 150 likes, 12 comments and 8 shares, the sum is 170 and the rate is 3.4%.
Two details matter when you compare videos:
- Like counts can change. YouTube’s help centre notes that some likes may be marked invalid and periodically removed from the counts, so a rate calculated today may not match one calculated next month.
- Shorts views are counted differently from before. Since 31 March 2025, a Shorts view counts each time a Short starts to play or replays, with no minimum watch time. The earlier metric is now called “engaged views” in YouTube Analytics. The same interactions divided by the new, larger view count will give a lower rate, so avoid comparing Shorts from before and after that date without checking which view metric you used.
YouTube’s Engagement tab also reports watch time and average view duration. Average view duration is calculated from engaged views and their watch time. For long-form content it is often a better guide to quality than likes.
What is a good engagement rate? How to read benchmarks
The Quid / Rival IQ figures above are the most recent public cross-platform medians I could verify, and they carry three caveats. They describe company accounts, not creators. They are medians, so half of the sampled accounts do better. And they are based on 150 randomly selected companies per industry, divided by followers.
Formula choice can swamp everything else. One 2026 roundup of benchmark sources noted that Hootsuite’s Instagram industry medians cluster in the 3–4% range while Rival IQ’s sit near 0.3%, because the two use different calculations. A creator comparing a reach-based rate with a follower-based benchmark will conclude they are doing far better than they are.
A workable standard for “good”:
- Use one formula and write it down.
- Compare each result with your own median from the last 10 posts or videos.
- Compare with accounts of a similar size and topic, measured the same way.
- Treat the trend over three to six months as more informative than any single post.
Common mistakes
- Comparing across tools. A rate from your scheduling app and a rate from a benchmark report are rarely the same measurement.
- Mixing formats. Reels, carousels, Stories and long videos behave differently. Calculate them separately.
- Judging from one post. A viral post lifts the average for weeks. The median resists that.
- Reading a low rate as proof of anything. A low rate on a large following can reflect inactive followers, content that has stopped resonating, or an audience that did not come from genuine interest, including purchased followers. The rate shows that something is off, not what.
- Stopping at the ratio. A rising rate means little if reach, watch time, clicks or sales are flat.
A five-minute routine
| Platform | Usual denominator | What to add up | Where to find the figures |
| Instagram (your account) | Reach, or followers | Likes, comments, saves, shares | Instagram Insights (business or creator account) |
| Instagram (another account) | Followers | Public likes and comments | The public profile |
| TikTok | Views | Likes, comments, shares (say whether you include saves) | TikTok analytics |
| YouTube | Views | Likes, comments, shares | YouTube Studio |
If you would rather not do the arithmetic by hand, GTRSocials publishes free engagement calculators for Instagram, TikTok and YouTube. Its pages describe the Instagram tool as comparing likes and comments with followers, and the TikTok and YouTube tools as comparing interactions with views, so check each one’s input requirements before relying on the output.
Whichever method you use, record your last 10 posts today, note the formula, and recalculate monthly. If the rate falls, look at your first few seconds, your format and your posting rhythm before you worry about the number itself.
