Calculate, read, then compare
Start with a public handle. Each platform has its own formula. Very fresh posts wait until their numbers stop growing fast.
Enter a public handle
Choose Instagram or TikTok and enter the public account's username. No login or account connection is needed.
Read the interaction counts
Read the percentage alongside average likes and comments. On TikTok, review average views too.
Compare within your group
Look for a comparison within your platform and follower class. It appears only when at least 30 analyzed profiles are in that group.
What your result shows
The engagement rate calculator gives you three numbers. Read them together, not one at a time.
Your engagement rate
how many reactions a post gets on average, measured against your followers (Instagram) or against a video's views (TikTok).
Likes and comments per post
the numbers behind the rate. When the rate moves, this tells you whether likes or comments drove it. TikTok adds average views per video.
Your class comparison
the share of profiles with a similar follower count on the same platform that have a lower rate. It appears once 30 profiles in your class were checked with the calculator in the last seven days.
How the calculator works it out
Instagram and TikTok measure engagement differently, so only compare a rate with rates from the same platform.
Instagram
- Formula
- (likes + comments) per post ÷ followers × 100
- Divided by
- Followers
- Not included
- Saves, shares, reach
TikTok
- Formula
- (likes + comments + shares) ÷ views × 100, per video, then averaged
- Divided by
- The video's views
- Not included
- Saves, watch time
Which posts count
The calculator reads your newest public posts. If you post several times a day, it keeps reading until a full week is covered, up to 96 posts. Pinned posts don't count, since they're often old and would skew the picture.
Very fresh posts wait while their numbers are still growing. How long depends on your rhythm: three times your usual gap between two posts, at least three hours and at most two days. If fewer than three posts are left after that, the calculator uses all of them.
What to do with your result
A rate is a starting point. Use it to change one thing, then measure again.
Write down your baseline
rate, likes and comments per post, with the date.
Find your strongest posts
Which ones have clearly more comments than average? Look at format, topic and the first line of the caption.
Change exactly one thing
a specific question in the caption, more Reels or a reply to every comment in the first hour.
Check again after two to four weeks
One strong post barely moves the rate. A new pattern across several posts does.
Common mistakes
Comparing platforms
5% on TikTok and on Instagram mean different things.
Comparing big and small accounts
Compare yourself with your class.
Counting giveaways
Leave them out when you want your usual rate.
Treating other tools as equal
Many divide by reach. Note the formula.
Measure engagement by reach
Reach and saves only show up in your own account's insights, not in public data. Connect your professional Instagram account to Crowdbird analytics to see those numbers for your posts.
If you want more comments, the caption generator helps you phrase a good question. And when someone asks for a link, comment-to-DM automation can send it by DM on Instagram and Facebook.
How do you calculate an engagement rate?
Divide the interactions you count by the audience measure you use, then multiply by 100. For Instagram, Crowdbird uses average likes plus comments per post divided by followers. For TikTok, it uses likes, comments, and shares divided by views per video. Keep the interaction types and denominator consistent when comparing results.
What is a good Instagram engagement rate?
A useful rate is one that holds up against your own previous results and comparable Instagram profiles, rather than a universal target. Crowdbird offers a comparison when at least 30 analyzed profiles belong to your platform and follower class. Without that group, focus on your average likes and comments and the kinds of posts that prompted them.
Is the engagement rate calculator free?
Yes, you can use the calculator without paying or creating an account. Enter a public Instagram or TikTok handle to get a result from public data. You do not need to connect your social account or share its password. Private accounts cannot be analyzed through this tool.
Why does the TikTok engagement rate calculator use views?
It uses views because TikTok distributes videos by views, so followers are not the denominator for this calculation. Likes, comments, and shares are measured against the video's views. An Instagram percentage answers a different question because its denominator is followers. Keep separate baselines for the two platforms, even when you publish the same content on both.
Does the calculator include posts published today?
Not right away. A post counts once it's three times as old as your usual gap between two posts, at least three hours and at most two days. If you post several times a day, that means after a few hours. Pinned posts never count. Profile data stays cached for six hours and post data for twelve, so checking again right away shows the same numbers.
Why is there no comparison for my profile?
Your comparison group may not yet contain at least 30 analyzed profiles. Crowdbird groups profiles by platform and follower size, so a large pool across all accounts is not enough. When your specific group is too small, the tool says there is no comparison yet. You can still use the calculated rate and interaction averages.
Can the calculator analyze private accounts or hidden metrics?
Private accounts cannot be analyzed, and a public-data calculation cannot recover interactions that are not publicly available. For your own account, use its Insights to examine metrics beyond the public counts. Public profile data is cached for six hours and post data for twelve hours, so repeated requests may not reflect every recent change.
