How to calculate engagement rate on Instagram
- Open the post's insights and note likes, comments, saves and shares.
- Add them together.
- Divide by your follower count and multiply by 100.
Instagram engagement rate = (likes + comments + saves + shares) ÷ followers × 100
Example: 250 + 20 + 15 + 10 = 295 interactions on a 10,000-follower account = 2.95%.
Engagement rate by reach on Instagram
Instagram also shows how many accounts each post reached. Dividing by reach instead of followers tells you how well the post did with people who saw it; use the engagement rate by reach calculator for that. Reels often reach non-followers, so ERR is usually the fairer check for Reels.
Checking another account's engagement
For a public account you can see likes and comments but not saves, shares or reach. Enter likes and comments only, leave the rest at 0, and average 6 to 12 recent posts. This is how most free Instagram engagement rate checkers work.

Instagram engagement rate example
Engagement rate = (likes + comments + saves + shares) ÷ followers × 100
Example: 15,000 followers and a post with 300 likes, 20 comments, 25 saves and 15 shares: 360 ÷ 15,000 × 100 = 2.4%, about five times the 0.48% average by followers reported by Socialinsider.

Frequently asked questions
Should I include likes from hidden like counts?
Yes. You can still see your own like counts in insights even if they are hidden publicly.
Why does Instagram show a different number?
Instagram's own 'accounts engaged' counts unique people, not total interactions, so it is usually lower.
