How the engagement rate is calculated
Engagement by followers is the average number of interactions per post — likes, comments, saves and shares — divided by your followers, times 100. It is the figure brands and agencies usually ask for, because it says how much of your audience reacts to what you post.
Engagement by views divides the same interactions by the views of those posts. It is fairer for Reels and TikTok, where most views come from people who don't follow you yet, and it is the figure TikTok creators usually quote. This calculator shows both when you give it the numbers.
What counts as a good engagement rate
There is no single good number: engagement by followers falls as accounts grow. A small account where friends and regulars see every post can reach 3 to 5% on Instagram, while accounts with hundreds of thousands of followers are doing well above 1 to 2%. TikTok rates are usually higher than Instagram's for the same size.
That is why the result is compared with accounts of your size, in ranges rounded from industry reports of recent years. Niches differ too — food, fitness and parenting tend to engage more than news or finance — so treat the range as a reference, and your own trend over time as the real benchmark.
Where to find your numbers
On Instagram, open a post and tap View insights (a professional account shows it; switching is free). You'll see likes, comments, shares, saves and views or reach. On TikTok, open a video, tap the three dots and then Analytics. Use recent posts of the same kind, not a single viral one, and skip paid promotions: they inflate views and lower the rate.
How to raise it
Comments grow when captions ask something easy to answer. Saves and shares grow with content people want to keep or send: tips, lists, before-and-afters, short tutorials. Posting when your audience is online, replying to comments in the first hour and using the first second of a video to say what it's about all help the platforms show the post to more people.
Buying followers is the quickest way to lower the rate: those accounts never interact, so every post is measured against people who aren't there. Brands check it, and a smaller, engaged audience is worth more to them.
Private by design
Nothing is fetched from Instagram or TikTok and you don't log in anywhere: the calculation runs in your browser with the numbers you type, so it works for private accounts and for any account you manage. Nothing is sent to us or stored.
