Engagement Rate Calculator
Work out your Instagram engagement rate by reach and by followers from your recent posts. Free, no sign-up, and every formula is shown.
Engagement rate by reach
11.27%
Interactions ÷ accounts reached. Best for comparing posts.
Engagement rate by followers
6.01%
Average interactions per post ÷ followers. Easy to compare across profiles.
Interactions per post
902
Likes + comments + saves + shares, averaged.
Saves + shares
17%
Share of interactions that are saves or shares — signs people found the post worth keeping or sending.
How these numbers were calculated
- Total interactions: 5,410 across 6 posts
- Average reach per post is 53% of your follower count
ER (reach) = interactions ÷ reach × 100 · ER (followers) = (interactions ÷ posts) ÷ followers × 100
There is no single "good" engagement rate. It varies with niche, audience size and format, so the most useful comparison is with your own past posts.
How to collect your numbers
- Open the Instagram app, go to your profile and tap Professional dashboard.
- Pick your most recent 6–12 posts of the same type (for example, only Reels). Don't skip the ones that did badly.
- On each post, tap View insights and note likes, comments, saves, shares and accounts reached.
- Add each column up across all the posts and enter the totals above, together with how many posts you counted and your current follower count.
A simple spreadsheet with one row per post makes this a five-minute job each month, and gives you a history you can compare against.
The formulas
Engagement rate by reach = (likes + comments + saves + shares) ÷ total accounts reached × 100
Engagement rate by followers = (total interactions ÷ number of posts) ÷ followers × 100
- By reach measures how the people who saw a post reacted. It is the better measure of content quality because it isn't distorted by followers who never saw the post.
- By followers is what most brands can estimate from the outside, so it is useful for comparing profiles side by side.
- Saves + shares share: a like takes a second; saving a post to come back to or sending it to a friend signals stronger interest. Brands selling considered purchases often pay attention to this.
Reading your results honestly
- Compare with yourself first. A creator whose rate rises from one month to the next is doing something right, regardless of what any other account is doing.
- Watch reach as well as rate. A very high rate on a post nobody saw is less useful to a brand than a slightly lower rate on a post that reached thousands of new people.
- Comments need reading, not counting. Ten real questions about a product are worth more than a hundred emoji replies. Brands increasingly scroll through comments before booking.
- Be wary of sudden spikes. Giveaways and engagement groups inflate likes and comments for a few posts; the rate drops again afterwards and experienced brands notice.

For brands checking a creator
Ask the creator for screenshots or a screen recording of Insights for their last several posts, then put the totals into this calculator yourself. Compare the result with what you can see on the public profile: likes and comments relative to followers should be in the same ballpark. Our guide on vetting creators before you pay lists the other checks worth doing.
Frequently asked questions
Which engagement rate should I share with brands?
Share both, and say which is which. Engagement by reach tells a brand how people who actually saw your posts responded, which is the fairer measure of content quality. Engagement by followers is easier for a brand to check from your public profile. Quoting a number without naming the formula invites confusion.
Why are my two engagement rates so different?
Because reach and followers are different sizes. If your posts usually reach fewer accounts than you have followers, engagement by reach will be higher than engagement by followers. If a Reel travels far beyond your followers, the opposite can happen. Neither is wrong; they answer different questions.
How many posts should I include?
Use your most recent 6 to 12 posts of the same format, and include the weak ones. Averaging only your best posts gives a number you cannot repeat, and brands who check your profile will notice the gap.
What is a good engagement rate on Instagram?
There is no single number. Engagement varies with niche, audience size, format and how you count interactions. Smaller, tightly focused accounts often see higher rates than very large ones. The most useful benchmark is your own history: track the same formula every month and watch the trend.
Can I use this for Reels?
Yes. For Reels, use "Accounts reached" from each Reel’s Insights as reach. Some creators prefer to divide interactions by plays or views instead; that gives a lower percentage because one person can watch several times. Whatever you choose, use it consistently.
Does Kollabary read my Instagram data?
No. This calculator runs in your browser on the numbers you type in, and Kollabary has no Instagram API integration. Your inputs are only remembered on your own device for convenience.
