The percentage of viewers who took an action (like, comment, share, save) divided by total reach or impressions.

Engagement rate = (likes + comments + shares + saves) ÷ reach × 100. The exact formula varies — some tools use followers as the denominator, others use impressions or reach. For benchmarking, use reach: a 4% engagement rate on reach is roughly the industry average for Instagram; 6%+ is strong; below 2% is weak.
Different actions weight differently. Saves and shares signal high value (the viewer wants to come back or send to someone else) and are the strongest algorithmic signals on Instagram. Comments are second. Likes are nearly worthless to most algorithms now — too easily faked, too automatic.
The metric is most useful as a relative measure: how does this post compare to my account's median? An account with 0.5% baseline engagement that hits 2% on a specific post is doing better, in algorithmic terms, than an account with 5% baseline that drops to 4%.
Engagement rate is the percentage of viewers who took an action divided by total reach or impressions: (likes + comments + shares + saves) ÷ reach × 100. Some tools use followers or impressions as the denominator instead, so always confirm which one a number is based on.
Benchmarked against reach, a 4% engagement rate is roughly the industry average for Instagram; 6% or higher is strong, and below 2% is weak.
Saves and shares signal the highest value — the viewer wants to come back or send the post to someone else — and are the strongest algorithmic signals on Instagram. Comments are second, and likes are nearly worthless to most algorithms now because they are too easily faked and too automatic.
The metric is most useful as a relative measure against your own account's median, not against other accounts. An account with a 0.5% baseline that hits 2% on a post is doing better in algorithmic terms than an account with a 5% baseline that drops to 4%.
Because the formula's denominator varies — some tools divide by followers, others by impressions or reach. For consistent benchmarking, use reach as the denominator.
