Engagement rate calculator
Six platforms, four denominators, and the benchmark that actually matches the one you picked. Free, nothing stored, the maths runs in your browser.
Engagements divided by your follower count. This is what media kits, agencies and every handle lookup tool use, because followers is the only number an outsider can see. Use it for anything external.
Your total follower count, for example 8,400.
Ten to fifteen recent posts is what the benchmark studies use. This works out both averages for you, the mean and the median, up to 15 posts.
Enter your followers and what the post got, and the rate appears here as you type.
How to calculate your engagement rate
- Choose the denominator before anything else. Followers if you are building a media kit or comparing accounts, reach or impressions if you are judging how a post performed, views on YouTube, TikTok and Reels. This one choice moves the answer more than everything else you enter put together.
- Add the engagements your platform actually counts. Instagram counts likes, comments, saves and shares. LinkedIn counts reactions, comments and reposts, and adds clicks in its own analytics. The calculator only asks for the ones that belong to the platform you picked.
- Read the rate against the matching benchmark. The tool shows the band for your platform, your account type and the denominator you chose, so a reach based rate is never scored against a follower based average. For a media kit, average ten to fifteen posts and copy the block.
Why every calculator gives a different answer
There is no single engagement rate formula. At least five denominators are in active use, and the one a tool picks can move the answer by more than ten times. That is the real reason the numbers never agree, and almost no tool tells you which denominator it used.
In a published comparison, one creator account was run through five popular calculators. The answers came back 1.07%, 1.19% and 4.50%, and one tool returned 112.52%, which is mathematically impossible for a follower based rate: it would mean every follower engaged more than once. That last figure is what you get when a tool adds up engagements across several posts and divides by a single post's denominator, so the number keeps climbing with every post you add.
Four things explain nearly every disagreement.
- The denominator
- Followers, reach, impressions or views. Reach is typically a fraction of your followers, so the same post can read 1.2% by followers and 6% by reach. This is the biggest single cause, and most tools never tell you which one they used.
- Sample size
- One post against twelve. A single strong post can double a one post rate. Benchmark studies read ten to fifteen posts, so a rate built from one post is not comparable with them at all.
- Mean or median
- HypeAuditor works from the median of your recent posts with outliers excluded. Phlanx and inBeat use the mean. Feed both the same twelve posts and they will still disagree, by a lot if one post went viral.
- The time window
- The last 30 days, the last 12 posts, or the lifetime of the account. A quiet month and a launch month produce different answers from the same account.
None of those tools is lying to you. They are answering different questions and printing the answers as though they were the same one. So this calculator makes the denominator a decision you make on purpose, shows you the formula with your own numbers in it, and only ever compares your result against a benchmark measured the same way.
What counts as an engagement on each platform
- Likes, comments, saves and shares or sends. Saves and shares are the two an outside tool cannot see, so public calculators are quietly working from likes and comments alone.
- TikTok
- Likes, comments and shares, with saves optional. Shares carry real weight on TikTok, so leaving them out understates the number.
- YouTube
- Likes, comments and shares. Views is usually the right denominator here rather than subscribers, because a video reaches far beyond the people subscribed to the channel.
- X
- Likes, replies and reposts, with bookmarks optional. You can see bookmarks on your own posts, so include them when you have them.
- Reactions, comments and reposts, with clicks optional. LinkedIn measures itself against impressions, not followers, which is why the calculator starts there when you pick LinkedIn.
- Reactions, comments and shares.
Two things worth knowing. First, LinkedIn's own analytics counts clicks as engagement, and including them roughly doubles your rate against most published benchmarks, which are built without them. Include clicks for internal reporting, leave them out when you are comparing yourself with anything external, and the calculator keeps them behind a separate toggle so the choice is yours.
Second, the handle lookup tools have a blind spot. Saves and shares are not visible on someone else's Instagram post, so a tool that only knows your handle can only ever work from likes and comments. You can see saves and shares in your own insights. Entering them here gives a more complete number than those tools are able to produce, which is the one real advantage of typing the numbers in yourself.
Direct messages are not part of the engagement rate on any platform, so nothing here asks for them.
Frequently asked questions
What is a good engagement rate?
It depends on three things, and any tool that answers with one number for everybody is guessing. Platform: Socialinsider's 2026 Social Media Benchmarks put brand accounts at 2.60% on TikTok and 0.45 to 0.48% on Instagram, both measured against followers. Follower tier: HypeAuditor's 2026 data puts Instagram creators with 1,000 to 5,000 followers at 4.8% and creators with 100,000 to 1 million at 1.0%. Denominator: measured against reach or impressions instead, Hootsuite's 2026 update puts Instagram at 3.5%. Pick your platform, your account type and your denominator in the calculator and it shows the band that actually matches.
Should I use followers or reach?
Followers for anything external. Media kits, rate cards, comparing yourself with another account: followers is the only number an outsider can see, so it is what brands and agencies compare on. Reach for judging your own content, because it tells you how many of the people who actually saw the post did something about it. The same post can have a poor follower rate and an excellent reach rate at the same time, and both readings are true. Just never compare one against a benchmark built on the other.
Why is my engagement rate over 100%?
The denominator is wrong. Above 100% would mean every single follower engaged more than once, which does not happen. Almost always someone has entered followers where reach belonged, or added up engagements across several posts and divided by one post's denominator. That second mistake is what produces the notorious 112.52% result you see quoted in tool comparisons. This calculator flags anything over 100% and refuses to score it, rather than printing a number it knows is impossible.
How many posts should I average?
Ten to fifteen recent posts. One post tells you almost nothing, because a single viral or flat post moves the number more than your actual performance does. Turn on the multiple posts option and the calculator works out both averages for you, the mean and the median, for up to 15 posts. If one post ran away with itself, trust the median.
Do you store my numbers?
No. The maths runs in your browser. There is no server call, no account and no log, so nothing is sent anywhere and nothing is kept. Close the tab and the numbers are gone.
