Engagement rate by followers
Formula: (likes + comments + saves + shares) ÷ followers × 100.
Use this when you compare accounts, build a media kit, or track long-term audience response. It answers: “How actively does my audience respond relative to how many people follow me?”
Engagement rate by reach
Formula: (likes + comments + saves + shares) ÷ accounts reached × 100.
Use this when you judge a single post or Reel. Reach changes every post, so this number tells you how the people who actually saw the content responded.
Which one should you choose?
- Media kit / brand outreach: followers.
- Post review and content testing: reach.
- Compare Reels with Reels and carousels with carousels before drawing big conclusions.
- Include saves and shares when you can — they often signal usefulness better than likes alone.
