Engagement rate is the share of people who interacted with a post. Add likes, comments, saves and shares, divide by your follower count (or by the post's reach), and multiply by 100. A post with 180 interactions on an account with 6000 followers has an engagement rate of 3%.
The two formulas
By followers is the version most people quote, because anyone can calculate it from a public profile:
(likes + comments + saves + shares) ÷ followers × 100
By reach is more accurate for your own analysis, because it measures the people who actually saw the post:
(likes + comments + saves + shares) ÷ accounts reached × 100
Saves, shares and reach are in each post's insights and are only visible to the account owner. If you are comparing someone else's account, you can only use likes and comments.
A worked example
| Post A | Post B | |
|---|---|---|
| Followers | 6000 | 6000 |
| Reach | 2400 | 9000 |
| Likes, comments, saves, shares | 180 | 270 |
| Rate by followers | 3.0% | 4.5% |
| Rate by reach | 7.5% | 3.0% |
Post B looks better by followers and worse by reach. Both are true. It was shown to many people who do not follow the account, and strangers interact less than followers do. This is normal for a Reel that gets recommended.
You can try your own numbers in the engagement rate calculator.
What counts as a good rate
There is no official benchmark, and published averages vary with how they were measured. Two patterns are consistent:
- Rates fall as accounts grow. A 2000-follower account often sees several percent; an account with a million followers is usually well under one percent.
- Rates differ by format. Carousels and Reels tend to collect more interactions than single photos.
Compare your posts with your own previous posts, not with an industry number.
Why the rate drops when followers jump
Engagement rate is a ratio. If followers rise faster than interactions, the rate falls even though nothing got worse. This happens after a viral Reel, a giveaway, or a purchased follower package. The honest reading is that the new followers are less engaged than the old ones, and the rate tells you by how much.
If a steady rate matters to you, for example when pitching brands, grow the follower count and the interaction counts together, and keep in mind that brands increasingly ask for reach and saves, not just the rate.
Three ways to raise it
- Ask for one specific action. "Save this for your next trip" outperforms "like and share".
- Reply in the first hour. Each reply is another comment and invites a second one.
- Post fewer, better carousels. Each swipe is time spent, and people who reach the last slide are more likely to save.
Frequently asked questions
Do views count toward engagement rate?
No. Views and reach measure how many people saw the post. Engagement counts the actions they took: likes, comments, saves and shares.
Is engagement rate by reach or by followers better?
Use reach for judging your own content, because it reflects who actually saw it. Use followers when you need to compare with other accounts, since reach is private.
