Look up a public Instagram or TikTok account, or enter your own numbers by hand. Either way you get the rate and the benchmark it should be judged against.
Engagement rate is the number brands actually price on. It is interactions per post divided by follower count, expressed as a percentage, and it answers the question a follower count cannot: when this account posts, does anyone respond?
This calculator has two modes for an honest reason. The automatic mode looks up a public Instagram or TikTok account and averages its recent posts. The manual mode works for any platform, including YouTube and Twitch, and for private accounts, because you supply the numbers from your own analytics. The manual mode is not a fallback, it is the more accurate of the two: your own analytics know things no outside tool can see.
How to use the Engagement Rate Calculator
- Automatic: choose Instagram or TikTok, paste a username, press Check. We average the account’s recent public posts.
- Manual: switch to the manual tab and enter follower count and the average likes and comments across your last ten posts.
- Read the rate against the benchmark shown for that platform and size band.
- Track it monthly. The trend is worth far more than a single reading.
The formula, and why everyone quotes a different one
The version used here is the one media kits and creator marketplaces use: likes plus comments, per post, divided by followers, times one hundred. Averaged over the most recent posts rather than the single best one.
Some tools divide by reach or impressions instead of followers. That produces a much higher, flattering number and it is not comparable with anyone else’s figure, so it is not used here. Views are shown alongside the rate but never folded into it: on TikTok views routinely run many times the follower count, and adding them would produce rates above 100 percent that mean nothing.
What counts as good, by platform and by size
Engagement falls as an account grows, so a single “good rate” number is misleading. These are the bands this tool grades against.
- Instagram: under 5,000 followers, 4 percent is healthy and 8 percent strong. Over 100,000, healthy is closer to 1.8 percent. Over a million, 1.3 percent is a good result.
- TikTok: much higher across the board. Under 5,000 followers, 10 percent is healthy. Over a million, 4 percent is still healthy.
- YouTube: likes and comments against subscribers. Around 3 percent is healthy for a mid-sized channel.
- Twitch: the least meaningful of the four, because Twitch engagement happens live in chat rather than on a post. Concurrent viewers against followers tells you more.
The signals hiding inside the rate
- The comment-to-like ratio. Real communities comment. A rate that is almost entirely likes, with comments in the low single digits per post, usually means passive reach rather than an audience.
- The spread between your best and worst post. A wide spread means your content is inconsistent, which is fixable. A narrow spread at a low rate means an audience problem, which is not fixable by posting more.
- A falling rate with rising followers. The classic sign of growth that is not audience: you are gaining accounts that do not care.
Frequently asked questions
Why can I not look up a YouTube or Twitch account automatically?
YouTube publishes likes per video but not reliably per channel in a form worth averaging, and Twitch engagement happens in live chat rather than on posts. Rather than produce a confident-looking number from the wrong inputs, those two use the manual tab.
What is a good engagement rate?
It depends entirely on platform and size, which is why this tool shows a benchmark next to your result rather than a single global threshold. As a rough guide, Instagram above 3 percent and TikTok above 6 percent are healthy for most account sizes.
My rate dropped when I gained followers. Why?
Because the denominator grew faster than the interactions did. That is the normal shape of growth, and it is also the warning sign for growth that came from the wrong audience. Watch the interactions per post, not just the percentage.
Does this work on a private account?
Not automatically, because its posts are not public. Use the manual tab with the numbers from your own analytics, which are better data anyway.
How many posts do you average?
Up to the twelve most recent public posts. Fewer posts means a noisier figure, and the result tells you how many it used.
