Calculated Results
Enter your followers (or reach) and post engagement to calculate engagement rate.
This Instagram engagement rate calculator divides the interactions on a post by your followers or by the post's reach. Enter likes and comments, and add saves and shares if you have them. It works for a single post, or for an average over several posts when you enter combined totals and the number of posts.
How Instagram Engagement Rate Is Calculated
A post gets 400 likes and 25 comments, which is 425 engagements. On an account with 10,000 followers the rate by followers is 4.25%. If the post reached 6,000 accounts, the rate by reach is 7.08%.
| Interactions counted | Engagements | By 10,000 followers | By a reach of 6,000 |
|---|---|---|---|
| Likes + comments | 425 | 4.25% | 7.08% |
| Plus 50 saves and 15 shares | 490 | 4.90% | 8.17% |
The rate changes with the basis and with which interactions you count. State both when you report a figure.
Average Engagement Rate Over Several Posts
One post can be unusually strong or weak. An average over recent posts is a steadier figure.
Ten posts with 4,000 likes and 250 comments in total have 4,250 engagements, or 425 per post. On 10,000 followers the average rate is 4.25%. In the calculator, enter 4,000 likes, 250 comments and 10 posts.
By reach, add the reach of all the posts together and enter the total. The calculator divides total engagements by total reach, so the number of posts is not used in that mode.
By Followers or By Reach?
- By followers can be worked out for any public account, because follower counts, likes and comments are visible. It is the usual choice for comparing accounts.
- By reach needs Instagram Insights, so it works only for your own posts. It measures how the people who saw the post responded.
Hootsuite describes the reach version this way: add up the engagements for a post, divide by its reach and multiply by 100. It lists likes, comments, shares, saves, click-throughs and DMs among the metrics commonly used. The explanation is on the Hootsuite Instagram engagement rate page.
What Is a Typical Instagram Engagement Rate?
The same Hootsuite page says Instagram Business accounts typically see engagement rates of 0.46% to 0.76%, and that it is common for the rate to dip as the follower count grows. The page does not give a date for those figures.
Treat any published average with care. Sources count different interactions and use different bases, so two figures are often not comparable. The most useful comparison is with your own earlier posts, measured the same way each time.
For TikTok, use the TikTok Engagement Rate Calculator. To track audience size, see the Follower Growth Rate Calculator. The Influencer Rate Calculator uses engagement rate when pricing a sponsored post.

Frequently Asked Questions
How do you calculate engagement rate on Instagram?
Add the likes, comments, saves and shares on a post, divide by your follower count and multiply by 100. A post with 400 likes and 25 comments on an account with 10,000 followers is 425 ÷ 10,000 × 100 = 4.25%.
What is the difference between engagement rate by followers and by reach?
By followers divides engagements by everyone who follows the account. By reach divides by the accounts that saw the post. The same 425 engagements are 4.25% of 10,000 followers and 7.08% of a reach of 6,000.
How do I calculate an average engagement rate over several posts?
Add up the engagements on all the posts, divide by the number of posts and then by followers. Ten posts with 4,250 engagements in total average 425 each, which is 4.25% of 10,000 followers.
Should I count saves and shares?
Count them if you can see them. Saves and shares appear in Instagram Insights for your own posts. For someone else's account you can usually see only likes and comments. Use the same set of interactions every time you compare.
What is a good engagement rate on Instagram?
Hootsuite reports that Instagram Business accounts typically see 0.46% to 0.76%, and notes that rates often dip as follower counts grow. Published figures use different formulas, so compare your rate with your own past posts first.
Where do I find reach?
Open the post on your own professional account and tap View insights. Reach is the number of accounts that saw the post. You cannot see reach for another account's posts.
