How to calculate engagement rate
Add what people did
Type in the post's numbers from its insights. Skip any you don't have.
Add who saw it
Type your followers, reach or views. Each one gives you another rate.
Compare with last week
Work out last week's post the same way and see which did better.
Three ways to work out engagement rate
Engagement rate is how many people did something with a post, out of how many could have. Each way below divides by a different number. See the formula with a worked example.
By followers is the quickest, since the count is on your profile. It ignores how many of them saw the post.
By reach counts only the people who saw it, so it's fairer to a post that travelled past your followers.
By views suits video, where one person can watch twice.
Worked examples
One post, two rates
120 likes, 14 comments, 6 shares and 9 saves make 149 interactions: 6.21% of 2,400 followers, or 8.05% of the 1,850 it reached.
A month of posts
10 posts that earned 935 interactions between them average 93.5 a post. On 5,000 followers that's 1.87% a post.
A video
300 interactions on 12,000 views is 2.50% by views.
Common questions
Start my weekWhat is a good engagement rate?
The networks don't publish one, so compare with yourself. Work out your recent posts the same way and see which ones beat your usual rate.
Should I use followers, reach or views?
Reach, if you can get it, because it counts the people who actually saw the post. Followers is the quickest. Whichever you pick, use the same one every time.
What counts as an interaction?
Likes, comments, shares and saves, whichever you fill in.
Can I work out a rate for several posts?
Yes. Add up the totals across the posts and type how many posts they cover. You get a rate per post.
Is my data stored?
No. The sums run in your browser.
