Formula / methodology

(likes + comments + shares + saves) / denominator x 100

Choose followers when you want an audience-size view.

Choose reach when you want a distribution-based view for a specific post.

Interpretation copy is deliberately directional because engagement norms vary heavily by format, audience, and content type.

Example inputs and outputs

Followers formula

Input: 100 likes, 10 comments, 5 shares, 15 saves, 5,000 followers

Input: Same engagement, 2,000 reach

Output: Engagement rate 6.50%

Common mistakes

Comparing follower-based and reach-based rates without noting the denominator changed.
Treating the result as a universal benchmark across Reels, Stories, and feed posts.
Leaving reach blank while expecting the reach formula to calculate.

Followers vs reach

The right formula depends on whether you are evaluating account context or post-level exposure.

Followers

Useful for a broader audience-normalized signal.

Reach

Useful when you want to compare actual distribution against response.

FAQ

Which denominator should I use?

Use followers for a broader audience-size benchmark. Use reach for a more post-specific distribution read.

Why are shares and saves optional?

Teams do not always have them available at first pass. The tool defaults them to 0 when left blank.
