Type in a creator's followers and the numbers from their recent posts. Get their engagement rate by followers and by views, with the formulas shown, so you can check a creator before you send them a gift.
Pick a platform, add the follower count, then add the numbers from one post, or up to 12 recent posts to get an average. You can type 12.5k or 1.2m if you like.
Public numbers only. Leave a box blank if you don't have it.

Engagement rate by followers
Add the followers count to see a rate.
by followers = (likes + comments + shares + saves) ÷ followers × 100
Shares and saves are usually private to the creator. If you add them for one creator, add them for everyone you compare.
Engagement rate shows how much of a creator's audience does something with a post. A like, a comment, a share and a save all count. Divide that total by a bigger number, either the creator's followers or the post's views, and you get a percentage you can compare from one post, or one creator, to the next.
A follower count only tells you how many people pressed follow, maybe years ago. Engagement rate tells you whether anyone is paying attention now. Before you ship free product to a creator, that is the better question to ask.
by followers = (likes + comments [+ shares + saves]) ÷ followers × 100
by views = (likes + comments [+ shares + saves]) ÷ views × 100
several posts: work out each post's rate, then average them
Example 1, Instagram. A creator has 10,000 followers. A post has 400 likes and 20 comments. (400 + 20) ÷ 10,000 × 100 = 4.20%.
Example 2, TikTok. A creator has 50,000 followers. A video has 40,000 views, 2,000 likes, 100 comments, 50 shares and 150 saves. That is 2,300 interactions. By followers: 2,300 ÷ 50,000 × 100 = 4.60%. By views: 2,300 ÷ 40,000 × 100 = 5.75%.
Use the same fields every time. A rate that counts likes only can't be compared with one that also counts saves.
By followers asks: of the people who follow this creator, how many reacted? On Instagram it is the one you can work out from public numbers, since views aren't shown on every kind of post. It also helps you spot an audience that has gone quiet.
By views asks: of the people who watched, how many reacted? On TikTok and YouTube, videos often reach people who don't follow the creator, so follower count is a shaky yardstick. By views is a better read on whether the content itself works.
Our advice: on TikTok and YouTube, look at both. By views tells you how the content lands. By followers tells you how active the creator's own audience is. If the two disagree a lot, open those posts and look.
We don't give you one, on purpose. What counts as healthy changes with the platform, the niche, the size of the account and the type of post. We don't have a source we trust enough to put a number on it, so we won't make one up.
Here is a better test. Work out the creator's last 6 to 12 posts. Is the newest post close to their usual rate? Then run two or three similar creators you're also considering through the same fields. Comparing like with like beats comparing to a number from a chart.
None of these proves a creator is faking anything. They are reasons to look closer or ask a question. This calculator can't spot fake followers. It only does math on the numbers you give it.

Once you've picked creators, work out what the gifting will cost with our gifting ROI calculator, or read how to calculate your real cost per gifted post. More free tools are on the tools page.
More on the formulas this calculator uses and what the numbers mean once you have them.
Add up the interactions on a post (likes plus comments, and shares and saves if you have them). Divide by the creator's followers, then multiply by 100. That gives engagement rate by followers. Divide by the post's views instead of followers to get engagement rate by views. For several posts, work out each post's rate and average them.
Count them if you can see them, and count them the same way every time. On Instagram, shares and saves are usually private to the creator, so you would need a screenshot of their insights. If you leave them out for one creator and include them for another, the two rates can't be compared.
It depends on the platform. On TikTok and YouTube, videos often reach people who don't follow the creator, so by views is usually the better read on how the content lands. By followers still tells you whether the creator's own audience is active. On Instagram, by followers is the one you can work out from public numbers.
We don't publish one. It changes with the platform, the niche, the size of the account and the type of post, and we don't have a source we trust enough to put a number on it. A better test is to compare a creator's newest posts with their own average, and to compare similar creators using the same formula.
No. It only does math on the numbers you type in. A low or odd-looking rate can be a reason to look closer, such as reading the comments or asking for an insights screenshot, but it does not prove anything on its own.
