Enter your follower count, the number of posts you are measuring, and the interactions those posts earned.
The two rates and what divides them
Both rates share the same numerator. They differ only in the audience they divide by, and that choice decides what the number can tell you.
- Interactions
- Likes + comments + shares + saves across the posts you count
- Engagement rate by followers
- Interactions / (followers × posts)
- Engagement rate by reach
- Interactions / total reach of the posts
- Interactions per post
- Interactions / posts
Followers measure the audience you built. Reach measures the audience the platform gave you.
A post that reaches far beyond your followers posts a low rate by followers and a high rate by reach, and both are true. The follower rate is the one brands and sponsors usually ask for because it is stable across accounts of the same size. The reach rate tells you how well the content worked with the people who saw it, which is the better question when you are deciding what to make next. The calculator reports what you enter: it does not pull numbers from any platform, and it cannot tell you which interactions came from real people.
Frequently asked questions
How do you calculate engagement rate?
Add likes, comments, shares, and saves for the posts you are measuring, then divide by your follower count multiplied by the number of posts. Multiply by 100 for a percentage. An account with 10,000 followers that earns 1,200 interactions across 4 posts has a 3% engagement rate by followers.
Should I use followers or reach as the denominator?
Use followers when comparing against other accounts or reporting to a sponsor, because follower counts are public and stable. Use reach when judging your own content, because it measures how the people who saw the post responded. Report which one you used, since the two can differ by several points.
What is a good engagement rate?
It depends on the platform, the account size, and the format. Smaller accounts usually post higher rates than large ones, and video and carousels usually outperform single images. Compare your own posts and periods against each other before comparing against a published average.
Do impressions count as reach?
No. Reach counts unique accounts that saw a post at least once. Impressions count every view, including repeat views from the same account, so a rate by impressions is always lower than a rate by reach. Enter reach if your platform reports it.
