How it's calculated
Engagement rate = (likes + comments + shares + saves) ÷ denominator × 100 Denominator = followers, reach or impressions Several posts: average of each post's rate
There is no single official engagement rate. Rate by followers shows how much of your audience responds and lets you compare accounts, but it ignores how many people a post reached. Rate by reach divides by the accounts that actually saw the post, so it judges the content itself. Rate by impressions divides by every time the post was shown, so it comes out lower than by reach when people see a post more than once. Brands and agencies each choose one, and some count only likes and comments: ask which formula a brief uses before comparing numbers.

About the Engagement Rate calculator
This engagement rate calculator measures how strongly people respond to a social media post: likes or reactions, comments, shares and saves, divided by followers, by reach or by impressions. Choose one post to see its rate and how much of it comes from likes alone, or several posts to get the average of each post's rate and the rate worked out from the totals. Creators use it to track their content, and brands and agencies use it to compare accounts before a sponsorship. There is no single official formula: platforms, analytics tools and agencies divide by different numbers and count different interactions, so the calculator lets you pick the denominator and shows each division, which makes it easy to match the method in a brief or media kit.
How to use it
- Choose “One post” or “Several posts”.
- Pick what to “Divide by”: followers, reach or impressions.
- For one post, enter “Likes or reactions”, “Comments”, “Shares or reposts” and “Saves or bookmarks”, and its reach or impressions if you chose those.
- For several posts, list the “Interactions per post” and, for reach or impressions, one figure per post in the same order.
- Read the engagement rate, and say which denominator you used when you share it.
Worked example
A post gets 540 likes, 48 comments, 22 shares and 40 saves: 650 interactions. By reach, with 9,500 accounts reached, the rate is 650 ÷ 9,500 × 100 = 6.84%. By followers, with 20,000 followers, it is 650 ÷ 20,000 × 100 = 3.25%. Five posts with 610, 480, 720, 390 and 550 interactions on an account of 15,000 followers average 3.67%, from 2.6% for the weakest post to 4.8% for the best.

Questions people ask
How do I calculate engagement rate?
Add the likes, comments, shares and saves on a post, divide by your followers, reach or impressions, and multiply by 100.
Should engagement rate use followers or reach?
Followers suits comparing accounts, because anyone can see a follower count. Reach suits judging content, because it only counts people who actually saw the post. Use whichever the brand or report asks for, and the same one every time.
Why is my rate by impressions lower than by reach?
Impressions count every time a post is shown, so one person who sees it twice counts twice. Reach counts that person once, so the same interactions divided by impressions give a smaller rate.
What is a good engagement rate?
It differs by platform, account size, niche and formula, so a single benchmark can mislead. Compare your own posts with each other over time, worked out the same way. To see how many of the people you reach go on to buy or sign up, use the conversion rate calculator.
Average of posts or rate from totals: which should I report?
The average of post rates gives every post equal weight; the rate from totals lets posts with more reach count more. They match when every post has the same denominator. Say which you used.
