Instagram engagement rate calculator
Calculate engagement by followers, reach, views or impressions. Enter sample totals or paste individual posts, compare the mean and median, and read dated follower-tier benchmarks.
Free, no sign-up. Runs in your browser, with no AI calls.
Instagram engagement rate divides interactions by followers, reach or views and multiplies by 100. For followers, use average interactions per post. Enter totals or paste post rows to see individual rates, their mean, median and pooled rate. Compare like-for-like with dated creator benchmarks. Inputs stay in your browser; no account lookup is needed.
How to use this tool
- Choose a consistent sample
- Use interactions from the same posts and time period. Choose followers, reach or impressions. For followers, enter the follower count. For reach or impressions, add those counts across all sampled posts. People can appear in several posts, so the reach total is not a unique audience for the period.
- Add the interactions
- Enter totals or paste one six-column row per post: followers, denominator, likes, comments, saves, shares. Use up to 100 rows. A missing interaction must be an explicit zero. Per-post results show the mean, median and pooled rate; none silently drops a malformed row.
- Read the formula
- By followers: divide interactions by posts, then followers, and multiply by 100. By reach or impressions: divide total interactions by the matching total and multiply by 100. Multiple actions can produce a rate above 100 percent. Compare only calculations using the same denominator and interaction definitions.
