Instagram Engagement Rate
Last reviewed: January 2026
A simple engagement rate formula and how to measure it consistently.
A simple engagement rate formula
A common starting point is: (likes + comments) / followers × 100.
Use the same formula for a consistent time window (for example, last 30 days) so comparisons stay meaningful.
What to watch out for
Follower count alone can be misleading if you have bursts of low-quality followers.
Compare like-for-like: similar post types, similar windows, and similar campaign context.
