What this calculator does
The Engagement Rate Calculator computes the two engagement formulas agencies actually report: engagement by reach (interactions divided by accounts reached) and engagement by followers (interactions divided by audience size). Enter likes, comments, shares and saves as a single interactions total, plus reach and follower count, to get both rates side by side. Use engagement-by-reach when judging content quality - it ignores dormant followers - and engagement-by-followers when benchmarking account health over time or against competitors. The calculator applies to Instagram, TikTok, Facebook and LinkedIn identically, which keeps multi-platform client reports consistent.
How to use this calculator
- 1
Total the interactions on the post or period: likes, comments, shares, saves.
- 2
Enter reach (accounts reached) and current follower count.
- 3
Report engagement-by-reach for content quality, by-followers for account benchmarking.
Why this matters for agencies
Engagement rate is the social metric clients understand best after follower count - and the one that actually correlates with distribution. Reporting it consistently, with the formula named, prevents the platform-to-platform confusion that erodes trust in social reporting.
Frequently asked questions
What is a good engagement rate?
By followers: 1-3% is solid on Instagram, 3-6% strong; TikTok typically runs higher (4-10% by reach); LinkedIn company pages 2-4% by reach. Smaller accounts naturally show higher rates - benchmark against similar audience sizes.
Engagement by reach or by followers - which is correct?
Both are valid for different questions. By reach measures how compelling the content was to the people who actually saw it; by followers measures how activated your audience is. Report which formula you used - the numbers differ substantially.
What counts as an interaction?
Likes, comments, shares, and saves are the standard set. Some agencies include clicks and profile visits; if you do, keep the definition constant across every report.
Why did my engagement rate drop as followers grew?
Normal. Larger audiences contain more passive followers, and platforms show content to a smaller fraction of big audiences. Track engagement by reach to separate content performance from audience-size effects.
