Basic formula
Add likes, comments, saves, and shares. Divide the total by followers, then multiply by 100. This gives a quick engagement rate percentage.
Follower rate vs impression rate
Follower-based rate is useful for account comparisons. Impression-based rate is useful when a post reaches non-followers or runs inside a campaign.
Use consistent metrics
Use the same formula each time so you can compare posts fairly. Do not mix reach, impressions, and followers randomly in reports.
Before making content decisions, open the Instagram engagement calculator and compare your recent posts using the same inputs.
