What the calculator gives you
Six answers from seven numbers.
Followers, posts, likes, comments, saves, shares and reach. That is all it takes to see how your recent posts landed and what to change next.
Rate by followers. The share of your audience that reacts to a typical post. This is the number most people quote and compare between accounts.
Rate by reach. The share of people who saw your posts and reacted. It tells you how good the posts are once they are in front of someone.
Interactions per post. Total reactions divided by the posts you counted, so a busy month and a quiet month compare fairly.
What the reactions are made of. Likes, comments, saves and shares as parts of the whole. Saves and shares tend to mean a post was useful enough to keep or pass on.
Where it sits on the scale. A marker on a general guide many marketers use, from low to very high, so you can read the number at a glance.
A one-sentence reading. What the number means and, when comments are thin, one change to try on your next post.

How the rate is worked out
Two formulas. Nothing hidden.
Every number in the calculator comes from the lines below. You can check each one by hand with the totals from your own insights.
// Engagement rate by followersreactions = likes + comments + saves + sharesper_post = reactions ÷ postsrate = per_post ÷ followers × 100 // Engagement rate by reachby_reach = reactions ÷ reach × 100
Posts is at least 1An empty or zero post count is read as one post, so the sum never divides by zero.
No followers, no rateWith followers empty the rate shows 0. With reach empty, the calculator asks you to add it.
- 1
Add the reactions
6,800 + 410 + 520 + 190 = 7,920
- 2
Divide by the posts
7,920 ÷ 12 posts = 660 per post
- 3
Divide by followers
660 ÷ 12,400 × 100 = 5.32%
- 4
Divide by reach
7,920 ÷ 96,000 × 100 = 8.25%
Why reach is not divided by posts. Reach is already the total for the posts you counted, so the reactions go straight over it. Use the same posts for every total: if you count 12 posts, add up likes, comments, saves, shares and reach for those 12 only.

Followers or reach Example
Two rates, two stories.
The same account can post a quiet photo its regulars love and a reel that travels far beyond them. Each rate sees a different side. Here is one example account, Harbour Dental, with 12,400 followers.
Read by followers to compare
Use it to set your account beside others, or to track your own month to month. It rewards posts that travel beyond your followers, like the reel.
Read by reach to judge the post
Use it to see how people respond once a post is in front of them, however many that was. The team photo reached few people, but almost a third of them reacted.
Where your number sits
A scale to read the number, not a target to chase.
Four bands help you put a rate in context. Treat them as a starting point: the comparison that tells you the most is with your own account.

Example account, by followersSame account, by reachBands are equal width for reading; the steps between them are not.
Compare with your own last month
The fairest comparison is with your own last month. Count the same number of posts each time and look at the direction.
Small audiences read higher
A small audience of regulars reacts more often than a large one. A neighbourhood café can sit in the very high band with nothing unusual going on.
Compare like with like
Each platform counts reactions its own way, and views are not reach. Compare Instagram with Instagram and YouTube with YouTube.
Where to find your numbers
Every total is already in your insights.
Each platform keeps post totals in its own place. Here is the path on each one, and the word it uses for reach.
Professional dashboardorMeta Business Suite→Insights→Content
Pick the date range, then open each post for likes, comments, saves, shares and accounts reached. Add them up for the posts you want to count.
FollowersReach
Professional dashboardorMeta Business Suite→Insights→Content
Reactions, comments and shares sit in each post's details, with reach beside them. Use the same range as your Instagram count if you post to both.
FollowersReach
TikTok
ViewsAnalytics→Content
Open a video to see likes, comments, shares and saves. TikTok reports views rather than reach, so the calculator asks for views.
FollowersViews
YouTube
ViewsYouTube Studio→Analytics→Content
Use subscribers in place of followers and views in place of reach. Likes, comments and shares are in each video's analytics.
SubscribersViews
Page→Analytics→Updates
Reactions, comments and reposts are listed for each update, with impressions in place of reach. Count reposts as shares.
FollowersImpressions
Count the same posts
Use one date range for every total. The last 12 posts or the last 30 days both work. When the likes come from one range and the reach from another, the rate stops meaning anything.
Write the range down next to the result, so next month you count the same way.
What moves the rate
Small changes that give people a reason to respond.
A rate goes up when more of the people who see a post have something to do with it. These six changes are easy to test, one at a time, over a month.
01
End with one clear question
A question with a short answer gets comments. Two questions, or an open one, get silence.
Clinic“Before a first visit, would you rather know the cost or how long it takes?”
02
Post something worth saving
People save what they will need again. Saves count as reactions and show a post was useful.
SalonA four-step aftercare card for colour-treated hair, in one image.
03
Show the people behind the counter
Faces and names make a business feel near. Regulars react to people they have met.
CaféThe person who roasts the beans, at work, with one line about the morning.
04
Open with the point
Put the answer in the first line of the caption and in the first second of a reel.
Clinic“Night guards: who needs one, and why” tells people what they will get.
05
Keep hashtags few and exact
Instagram counts at most 5 hashtags per post (since December 2025). Choose five that describe the post and the place.
CaféThe drink, the bake, the street, the town, the café's name. Nothing broader.
06
Crop for the grid
Instagram's profile grid is 3:4. Keep faces and key detail inside that frame so the post reads in the grid too.
SalonFrame the finished cut in the centre, with room above and below.
For your kind of business
What to post, and what to watch, by kind of business.
Every business earns reactions for different reasons. Four example accounts show where to look first once you have your rate.
Harbour DentalEmma Clarke · Example
Clinic
- Post
- Answers to the questions patients ask at the desk, the team, and what a first visit looks like.
- Watch
- Saves and shares. People keep advice they may need later and pass it to family.
Loft Hair StudioClaire Morton · Example
Salon
- Post
- Finished work with the client's consent, short styling reels, and care tips for the week after.
- Watch
- Comments and saves. A question about a look is a sign someone is thinking of booking.
Oak & Ember CoffeeDaniel Reyes · Example
Café
- Post
- What is new on the counter today, the people who make it, and the room at its best hour.
- Watch
- Rate by reach on local posts. You want people nearby to see them and react.
Hana Sato StudioHana Sato · Example
Studio
- Post
- Class moments, one move explained well, and the timetable for the week ahead.
- Watch
- Comments and shares. Members tag friends when a class looks like one they would enjoy.

Questions
Questions about engagement rate.
Short answers to what people ask most when they first work out their rate. For anything about your own account, start with the free check.
What is a good engagement rate?
On a general guide many marketers use, 1–3% is average for most business accounts, 3–6% is high and over 6% is very high. Small, close audiences often sit higher. The fairest comparison is with your own last month.
Should I use the rate by followers or by reach?
Use both. The rate by followers shows how your audience responds to a typical post and is the one people compare. The rate by reach shows how good a post is once someone sees it. When the two point in different directions, the reason is usually how far the posts travelled.
Why is my rate by reach higher than my rate by followers?
When each post reaches fewer people than you have followers, the same reactions are divided by a smaller number. In the example, 96,000 reached across 12 posts is 8,000 a post, below 12,400 followers, so the rate by reach comes out higher.
How many posts should I count?
Enough to smooth out one lucky or unlucky post. The last 12 posts or the last 30 days both work. Use the same count each time you compare.
Do reels, stories and videos count?
Count whatever you want to measure, as long as every total comes from the same posts. It helps to measure feed posts and reels together and stories apart, because stories are counted differently.
Does it work for TikTok, YouTube and LinkedIn?
Yes. Pick the platform at the top of the calculator and the labels change: TikTok asks for views, YouTube for subscribers and views, and LinkedIn for impressions in place of reach.
Is anything I type saved or sent?
No. The calculator runs in your browser. Nothing you type leaves the page, and there is no password or login.
Why does my number differ from another calculator?
Some calculators leave out saves and shares, or divide by followers without dividing by posts first. This one shows its formula, so you can check every step by hand.
How is this different from the Growth Review?
The calculator gives you one number from the totals you type. The Growth Review, coming soon, looks at every post from the last 90 days on your Instagram or YouTube, sets out what holds you back, and gives you a 30-day plan as a PDF.
