Engagement rate is likes, comments, shares and saves divided by reach or followers, multiplied by 100. Median rates per follower are about 2.60% on TikTok, 0.48% on Instagram, 0.15% on Facebook and 0.12% on X. Use reach as the denominator to judge whether content worked, and followers when comparing accounts or evaluating a creator.
How to calculate engagement rate
Add up the interactions a post earned, then divide by the audience and multiply by 100. The interactions usually counted are likes, comments, shares and saves. Saves matter more than their volume suggests on Instagram, since saving signals genuine intent rather than a reflex tap.
The disagreement is over the denominator, and it changes the answer substantially. Dividing by followers measures how well you activate the audience you have. Dividing by reach measures how compelling the post was to the people who actually saw it. A post that reaches far beyond your following will score poorly by followers and well by reach.
Which denominator to use
Use reach when judging content. It is the fairer measure of whether a post worked, because it only counts people who had the chance to engage, and it is not distorted by an inflated or inactive follower count.
Use followers when comparing accounts or evaluating a creator, because reach is private data you will not have for anyone else. Almost every published benchmark and every influencer marketing rate card is calculated on followers, so that is the number to quote externally. This calculator returns both so you are never comparing one against the other by accident.
Engagement rate by platform
The arithmetic is identical everywhere, but what counts as an engagement is not, so the same post scores differently depending on which platform's convention you follow. On Instagram, count likes, comments, shares and saves. Saves carry unusual weight because saving signals intent to come back, and the platform treats it accordingly when deciding distribution.
TikTok engagement rate is usually calculated on views rather than followers, since TikTok distributes heavily to non-followers and a follower-based figure would be meaningless. Count likes, comments, shares and saves against video views. YouTube engagement rate works the same way: likes and comments against views, not subscribers. For both, enter views in the reach field above.
LinkedIn counts reactions, comments and reposts against impressions, and rates run lower than on consumer platforms because feed behaviour is different. Facebook follows the Instagram pattern. X and Twitter engagement rate conventionally includes replies, reposts, likes and bookmarks against impressions, which the platform exposes natively on every post.
What engagement rate tells a paid team
Organic engagement rate is a cheap read on whether a creative concept has legs before you put budget behind it. A post that earns saves and shares organically is signalling the same thing a strong thumb-stop rate signals in paid: the idea holds attention.
It is a leading indicator, not a substitute for performance data. Engagement and conversion are different behaviours, and creative that entertains does not always sell. Treat a strong organic post as a candidate worth testing in paid, then judge it on cost per acquisition against your break-even.
Engagement rate benchmarks
Benchmarks are a sanity check, not a target. Your own account history on the same audience and placement is always the better comparison, but these are the numbers to reach for when you have none.
Median engagement rate by platform
Calculated per follower across 70 million posts, January 2024 to December 2025 (Socialinsider). Rates fell on every platform year over year: Facebook 36%, TikTok 34%, Instagram 16%, X 48% (Rival IQ, 2025).
| Platform | Median engagement rate | Denominator |
|---|---|---|
| TikTok | 2.60% | Per follower |
| 0.48% | Per follower | |
| 0.15% | Per follower | |
| X (Twitter) | 0.12% | Per follower |
Frequently asked questions
How do you calculate engagement rate?
Add likes, comments, shares and saves, divide by your audience, and multiply by 100. Dividing by reach gives engagement rate by reach; dividing by followers gives engagement rate by followers. A post with 1,024 interactions reaching 31,000 people has a 3.3% engagement rate by reach.
Should I use reach or followers as the denominator?
Use reach to judge whether a piece of content worked, because it only counts people who could have engaged. Use followers when comparing accounts or evaluating creators, because reach is private and almost all published benchmarks and rate cards are calculated on followers.
What is a good engagement rate on Instagram?
Rates fall as follower count rises, so compare like for like. Smaller accounts routinely post rates several times higher than large ones on the same content, because their audiences are more recently acquired and more active. Judge against accounts of a similar size, and against your own history.
How do you calculate TikTok engagement rate?
Add likes, comments, shares and saves, divide by video views, and multiply by 100. TikTok engagement rate is calculated on views rather than followers because the For You page distributes heavily to people who do not follow you, which makes a follower-based figure misleading. Enter your view count in the reach field above.
How do you calculate YouTube engagement rate?
Add likes and comments, divide by views, and multiply by 100. As with TikTok, views rather than subscribers is the right denominator, because YouTube surfaces videos to non-subscribers through search and recommendations. Some analysts also include shares and the subscriber gain a video drove.
How do you calculate LinkedIn engagement rate?
Add reactions, comments and reposts, divide by impressions, and multiply by 100. LinkedIn reports impressions natively on every post. Rates typically run lower than on Instagram or TikTok because professional feed behaviour is less reflexive, so compare LinkedIn to LinkedIn rather than across platforms.
What is a good engagement rate for an influencer?
Judge it against account size, because rates fall as follower counts rise. A creator with 10,000 followers posting 5% is unremarkable; the same rate at 500,000 followers is exceptional. Since you cannot see a creator's reach, use the follower-based figure this calculator returns, which is what rate cards and influencer platforms quote.
Do saves count as engagement?
Yes, and on Instagram they carry more weight than their volume suggests. A save signals intent to return to the content, which is a stronger signal than a like, and the platform treats it accordingly when deciding distribution.
