Post Engagement & Reach Metrics

Engagement Rate (By Followers)4.99%1,745 total engagements ÷ 35,000
Engagement Rate (By Reach)7.27%1,745 engagements ÷ 24,000 views
Total Post Engagements1,745Likes + comments + saves + shares

Engagement Rate by Followers & Reach Formula

ERR (By Reach) = (Total Engagements / Total Reach) × 100; ERF (By Followers) = (Total Engagements / Total Followers) × 100
  • Total Engagements: Sum of likes, comments, shares, saves, retweets, and video bookmarks.
  • ERR (Engagement Rate by Reach): True engagement percentage of people who actually saw the post.
  • ERF (Engagement Rate by Followers): Traditional standard benchmark comparing engagements against total account followers.

Step-by-Step Worked Example

Scenario: Instagram carousel post with 1,250 likes, 180 comments, 220 saves, and 95 shares from a profile with 35,000 followers and 24,000 reach

Calculation Steps:

  1. Calculate total interactions: 1,250 + 180 + 220 + 95 = 1,745 engagements
  2. Calculate ER by followers: (1,745 / 35,000) × 100 = 4.99%
  3. Calculate ER by reach: (1,745 / 24,000) × 100 = 7.27%
Result: The post achieved an outstanding 4.99% engagement rate by followers and 7.27% engagement rate by reach, well above industry benchmarks.

Frequently Asked Questions

What is considered a good engagement rate on Instagram?

For accounts with 10k–100k followers, an engagement rate between 1.5% and 3.5% is average, while anything above 4.0% is considered high and indicative of an active community.

Why is Engagement Rate by Reach more accurate than by followers?

Due to algorithmic feed filtering, only 10%–25% of an account’s followers typically see any given organic post. Engagement by Reach measures interactions against the actual viewers.
