About this tool
What the Instagram Engagement Rate Calculator does
Engagement rate is the share of your audience that interacts with a post. It is usually calculated by followers, which makes accounts comparable, and by reach, which shows how compelling the post was to the people who actually saw it.
Formula
- Interactions = likes + comments + saves + shares
- Engagement rate by followers = interactions per post ÷ followers × 100
- Engagement rate by reach = interactions ÷ reach × 100
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Likes | 1,200 |
| Comments | 85 |
| Saves | 140 |
| Shares | 60 |
| Followers | 40,000 |
| Reach (optional) | 15,000 |
| Number of posts these totals cover | 1 |
| Result | Value |
|---|---|
| Engagement rate by followers | 3.71% |
| Engagement rate by reach | 9.90% |
| Interactions per post | 1,485 |
| Total interactions | 1,485 |
How to read the result
Saves and shares are stronger signals of value than likes, so look at them separately when you compare formats.
Engagement rate by followers usually falls as accounts grow. Compare yourself with accounts of a similar size rather than with a single benchmark.
