This engagement rate calculator measures how actively your audience interacts with your posts on Instagram, TikTok, YouTube, Facebook, LinkedIn or any other platform. Enter your followers and the totals from your recent posts to get engagement by followers, by reach and by views.
Engagement rate formulas
- By followers: (likes + comments + shares + saves) ÷ number of posts ÷ followers × 100
- By reach: total interactions ÷ total reach × 100, which shows how engaging posts are to the people who actually saw them.
- By views: total interactions ÷ total views × 100, common for video platforms such as TikTok and YouTube.
Worked example
An account with 20,000 followers gets 4,500 likes, 300 comments, 150 shares and 250 saves across 10 posts. That is 520 interactions per post, an engagement rate of 2.6% by followers.
Which rate should I use?
Brands often ask for engagement by followers because it can be checked publicly. Engagement by reach or views is fairer for your own analysis, because only some followers see each post. Use the same method each time so you can compare.
How to improve engagement
- Ask clear questions and reply to comments quickly.
- Post formats your audience saves and shares, such as tips, how-tos and carousels.
- Check your analytics for the days and times your followers are most active.
Frequently asked questions
What is a good engagement rate?
It depends on the platform, niche and account size. Smaller accounts usually have higher rates, and video platforms often show higher rates than image-based ones. Track your own trend over time.
Should I count views as engagement?
No. Views show reach, not interaction. Use them as the denominator for engagement by views instead.
How many posts should I include?
At least 10 recent posts gives a steadier result than a single post, which can be skewed by one viral hit.
Why do brands care about engagement rate?
It suggests how likely an audience is to notice and act on sponsored content, which follower count alone does not show.
