Engagement rate by followers
5.15%
(420 + 18) ÷ 8,500 × 100 = 5.15%
Likes and comments relative to follower count. This is not the percentage of unique people who engaged, or the percentage reached.
A worked engagement-rate example
With 8,500 followers, 420 average likes and 18 average comments per post, the calculation is (420 + 18) ÷ 8,500 × 100 = approximately 5.15%. These are demonstration inputs, not measurements from a customer account.
How to average several posts
If ten posts received 4,200 likes and 180 comments in total, divide each total by ten and enter 420 and 18. Entering the totals would make the result ten times the per-post rate. If follower count changed substantially, calculate individual posts using their follower count at the time instead.
Make the comparison fair
- Give posts the same amount of time to collect interactions.
- Separate Reels, images, carousels and promoted posts.
- Keep the included interactions and denominator consistent.
What the result does not tell you
Non-followers can interact and one person can leave multiple comments. This rate does not establish unique audience participation, sales conversion, follower authenticity or future reach. Read the comments and compare the outcome with your actual content goal.
Method and data source
The data source is your input. This tool uses no external account sample or live industry average. Use the previous-period field and snapshot to compare your own records without changing the calculation method.

Frequently asked questions
How do you calculate Instagram engagement rate?⌄
Divide likes plus comments by followers, then multiply by 100. For multiple posts, use average likes and average comments from the same set of posts.
Is a 5% engagement rate good?⌄
A rate alone cannot establish performance. Compare the same formula, content format, niche and paid or organic context. This tool does not assign industry percentiles or an account-quality score.
Does this include saves, shares or reach?⌄
This calculator includes likes and comments only, with followers as the denominator. Do not directly compare it with rates that include saves or shares, or divide by reach.
Does the calculator fetch my Instagram data?⌄
No. It calculates in your browser from the numbers you enter. No Instagram login or password is required.
How should I read the change between periods?⌄
A move from 3% to 4% is an increase of 1 percentage point. Compare periods of the same length and similar post formats.
