Engagement rate

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%.
