Engagement rate calculator

How much people interact with your posts, measured on your followers and on the people who actually saw them.

Engagement rate by followers

5.17%

by reach: 8.62%

517 interactions
8.62% by reach

With 517 interactions and 10,000 followers, your engagement rate is 5.17%: that’s 5.17 interactions for every 100 followers.

Among the 6,000 accounts that saw the post, it’s 8.62%. That’s the fairer number, because it counts only people who actually saw it.

Saves

If the app doesn’t show them, type 0. YouTube doesn’t count saves on videos, so they’re left out there.

Followers or subscribers

Reach or views

Instagram: accounts reached, in the post’s insights. TikTok and YouTube: views. Type 0 if you don’t know.

How many posts

If you added up the numbers from several posts, reach included, enter how many posts. The calculator gives the average per post.

How it works

Add up the post’s interactions: likes, comments, shares and saves. YouTube has no saves on videos, so there it’s likes, comments and shares.
Divide by the base and multiply by 100. The most common base is followers (subscribers on YouTube). The fairer one is the people who actually saw the post: accounts reached on Instagram, views on TikTok and YouTube.
For several posts, add everything up and divide by the number of posts: an average per post compares better than a single post.

Worked example

An Instagram post with 450 likes, 30 comments, 12 shares and 25 saves has 517 interactions. With 10,000 followers: 517 ÷ 10,000 = 5.17%. The post reached 6,000 accounts: 517 ÷ 6,000 = 8.62%. A TikTok video with 3,620 interactions, 25,000 followers and 80,000 views is 14.48% by followers but 4.53% by views.

Good to know

No platform publishes an official engagement rate formula: it’s a convention used by creators and brands. What’s official is what each count means.
You won’t find “good” benchmarks here: the figures that get quoted change from one source to another and from year to year. The most useful comparison is with your own posts, over time, always on the same base.
By followers, the number drops when few of them see the post; by views, it also counts people who don’t follow you. To compare two numbers, always use the same base.
Instagram counts total interactions minus unlikes, unsaves and deleted comments, so the numbers can shift a little in the days after you post.
Bought or fake likes and comments inflate the number without bringing you anything. YouTube, for example, checks its counts and discards low-quality views.

Frequently asked questions

How do you calculate engagement rate?

Add up a post’s likes, comments, shares and saves, divide by your followers and multiply by 100. With 517 interactions and 10,000 followers, that’s 5.17%. Divide by the accounts reached instead, and the number is usually higher: with 6,000 accounts reached, it’s 8.62%.

What is a good engagement rate?

There’s no official benchmark: the figures that get quoted change from one source to another and from year to year. It’s more useful to compare your own posts, on the same base, and watch whether the average goes up or down.

Should I use followers or reach?

The rate by followers is the most common and the easiest to compare with other accounts. The rate by reach is fairer, because it counts only people who saw the post. On TikTok and YouTube, where views can come from people who don’t follow you, the rate by views is often used.

What do I count for an Instagram reel?

Likes, comments, shares and saves: the total interactions Instagram shows in the reel’s insights. As the base, accounts reached: the unique accounts that saw it at least once.

Why is my TikTok engagement rate by followers so high?

Because a TikTok video can reach many people who don’t follow you: the interactions grow, your followers don’t. A video with 3,620 interactions and 25,000 followers is 14.48% by followers, but 4.53% of its 80,000 views.
