How it works
The idea is simple: of the people who could have responded, how many did? Interactions are usually likes, comments, saves and shares added together. The complication is the bottom half of the fraction. Dividing by followers measures how the post did relative to the size of the audience. Dividing by reach measures how it did among people who saw it. Dividing by views suits video. The three give different numbers for the same post.
That is why two engagement rates can only be compared if they were calculated the same way. When a post reaches fewer people than you have followers, its rate by reach is higher than its rate by followers. When a Reel travels far beyond your followers, the opposite happens. Published benchmarks mostly use followers, because follower counts are public, while your own Insights make reach easy to use. State the method whenever you quote a rate.
Creators use engagement rate to compare their own posts, to spot which topics and formats land, and in media kits when pitching brands. There is no universal good rate. It shifts with account size, niche, format and method. The most useful comparison is your own recent posts, measured the same way at the same age.
A worked example
A post on an account with 20,000 followers reached 10,000 accounts and got 500 likes, 50 comments, 100 saves and 25 shares.
- Add the interactions: 500 + 50 + 100 + 25 = 675.
- By reach: 675 / 10,000 = 6.75%.
- By followers: 675 / 20,000 = 3.38%.
- Same post, two honest answers. Neither is good or bad on its own. Compare it with the account's last ten posts measured the same way.
An illustration, not a real account. Any numbers in it are made up to show the method, and are not benchmarks.
Common mistakes
- Comparing a rate by reach with a benchmark by followers. The methods are not interchangeable.
- Chasing a universal good number. It depends on niche, size, format and method.
- Counting only likes. Saves and shares are often the stronger sign that a post was useful.
- Reading a low rate as a penalty. A low value alone does not show that an account is restricted.
Questions people ask
What is a good engagement rate on Instagram?
There is no universal good rate. For context only, the sources on this page give one published benchmark, which measures company accounts by followers. Your own recent posts are the better comparison.
How do I calculate engagement rate?
Add likes, comments, saves and shares, divide by reach, views or followers, and multiply by 100. Use the same bottom number every time. The free calculator linked on this page does all three.
Should I use reach or followers?
Use reach to judge how a post did among the people who saw it. Use followers when you compare with public benchmarks or other accounts, since their reach is private.

For a reel, Meta defines reach as the number of unique Instagram users that have seen it at least once, and total interactions as likes, saves, comments and shares minus unlikes, unsaves and deleted comments.
