Whether you read Influencer Marketing Hub in 2024, 2025 or this year, if an engagement calculator is what you were after, there's one on this page. It works inside your browser, and nothing you enter is sent to us. Below it, how Growsterr works, for anyone who read about growth services there and wants to know what we actually do.
How many of your followers react to a typical post. Enter the numbers from your last few posts.
The rate rises when the people who follow you actually care about your posts. Followers who never react lower it, whatever their number.
Three monthly packages. New followers, likes, views and comments come together, from the same real people.
For new and small accounts
$79.99 / month
1,000–4,000 followers / month
For creators ready to grow faster
$149.99 / month
2,000–8,000 followers / month
For established creators and brands
$279.99 / month
4,000–16,000 followers / month
Typical monthly ranges, not a fixed count: every one of your new followers is a real person who chose to follow, so every month is a little different.
Every package brings the whole picture, from the same real people.
Real people who discovered your profile and chose to follow. Typically 1,000–4,000 a month with Starter Creator.
Typically 2,000–12,000 a month with Starter Creator, on the posts they enjoy.
Typically 100–400 a month with Starter Creator. Written by people, never scripted.
The same people watch your posts on their own. We don't count views in advance: each one is a person.
A little every day, from the location you choose. Never all at once.
What we measured, day by day: visits from your campaign and the new followers they brought.
Average the likes and comments on a few recent posts, then divide by your follower count. The result is the share of your followers who react to a typical post, and the calculator does the arithmetic for you.
There's no single good number. What matters is your own trend: a rate that holds or rises as your audience grows means the new people care about what you post.
Engagement rate is the quickest way to spot fake followers: every account that never reacts pushes the rate down a little further. Real people who chose to follow can hold it up, because some of them like and comment.
A monthly subscription: you choose the package, we run the campaign, real people decide.
Starter Creator, Rising Influencer or Pro Influencer, billed monthly. Cancel any time from your account.
Tell us your Instagram username and where your audience should come from. We never ask for your password.
Every day your profile is shown to real people. Those who like what they see follow, like and comment, on their own.
Visits from your campaign and the new followers they brought, day by day. Measured numbers, never guesses.
No. Growsterr is a product of Sterr Agency (Sterr Technologies OÜ, Tallinn, Estonia). We're not connected to Influencer Marketing Hub.
No. The calculation happens in your browser, and nothing you type leaves the page.
Rather than chase someone else's benchmark, compare yourself month to month. A steady or rising rate while your follower count grows is the healthy sign.
We bring real people who can react, so new followers don't drag your rate down the way fake ones do. We don't promise a particular rate, because each person chooses what to react to.
Yes, the same way: average likes and comments per video, divided by followers. On YouTube, use subscribers in place of followers.
Choose a package and we start your campaign. Real people decide the rest, and your dashboard shows what we measured.
