## Engagement rate: how to calculate it and what counts as a good value
You calculate engagement rate as the ratio of interactions to followers, reach or views. We show three formulas using one example, explain where to find the data and why values should not be compared between platforms.

### In short
- Engagement rate is the share of interactions (likes, comments, saves, shares) relative to a chosen base, multiplied by one hundred.
- The base can be the number of followers, reach (unique viewers) or the number of views, and each formula gives a different result.
- You can find the data for free in Instagram Insights and YouTube Analytics; for TikTok, check the statistics in the app.
- Platforms do not publish any “good” benchmark, so the most useful approach is to compare your results with your own previous posts.
- Buying followers increases the denominator but not the number of interactions, so the engagement rate calculated from followers will decrease.
You calculate engagement rate by adding up the interactions on a post (likes, comments, saves and shares), dividing them by the chosen base and multiplying by one hundred. The base is usually the number of followers, reach or the number of views. Each formula gives a different figure, so always state which one you used and compare only results calculated in the same way.
### What is engagement rate?
Engagement rate is the percentage of people or actions that responded to content, relative to how many people could see or did see the content. It therefore does not measure the size of a profile, but how strongly the content appeals to the audience that has access to it. Brief definitions of other terms, such as reach or social proof, can be found in the glossary
.
Interactions are usually considered to be:
- likes (marked as “Like”),
- comments ,
- saves to bookmarks or collections,
- shares (forwarding in a message, to a story, or to another network).
Instagram adds up these actions in Insights into the “Interactions” metric, which it describes as the number of actions people take on content, such as likes, comments, saves and shares ( Instagram Help Center on Insights
, as of October 2026). Views are not counted as interactions; they serve as the basis for the calculation.
### What formulas are used to calculate the engagement rate?
There are three main formulas, which differ only in their denominator. The numerator is always the total number of interactions on one post (or over a period).
Formula Calculation What it reflects When to use it
From followers interactions ÷ number of followers × 100 How the audience responds relative to the size of the profile Comparing other profiles where you do not know the reach
From reach interactions ÷ reach (unique accounts that saw the content) × 100 How many of the people who saw the content responded Evaluating your own content
From views interactions ÷ number of views × 100 How many interactions there are per play Videos where one person may play the content multiple times
#### Sample calculation on a single post
Imagine a profile with 2,000 followers. One post has these figures (a fictional example for illustration):
- 120 likes, 15 comments, 10 saves and 5 shares, making a total of 150 interactions,
- reach of 3,000 unique accounts,
- 4,500 views.
- From followers: 150 ÷ 2 000 × 100 = 7,5 %.
- From reach: 150 ÷ 3 000 × 100 = 5 %.
- From views: 150 ÷ 4 500 × 100 ≈ 3,3 %.
All three figures are correct. The difference arises because the post was also seen by people who do not follow the profile, and some of them played it more than once. Therefore, it makes no sense to compare 7.5% for one profile with 3.3% for another unless you know how the figures were calculated.
#### Engagement rate over a longer period
A single post may be an exception. A more reliable picture comes from the average or median of the last 10–20 posts of the same format. The median (middle value) is more resistant to a single viral post that would skew the average.
### Where can you find the necessary data on Instagram, TikTok and YouTube?
All three platforms offer free statistics directly in the app or web interface. However, none of them shows the engagement rate as a ready-made figure in the same form, so you will need to calculate it yourself.
#### Instagram Insights
According to Instagram's help, Insights are available for public accounts and show, among other metrics, the following (status as of October 2026, source
):
- Views – how many times the content was played or displayed (the basis for the views-based formula),
- Viewers – unique accounts that saw the content (corresponds to reach),
- Interactions – the sum of likes, comments, saves and shares (the numerator),
- Engaged accounts – unique accounts that interacted with the content,
- Total number of followers – follower growth and activity; more detailed data is shown only from 100 followers.
Data can be viewed in the app and on instagram.com for a preset or custom period within the last 90 days. Open the statistics for an individual post using the statistics button located directly on it. If you want to keep a longer history, record the figures regularly in a spreadsheet.
#### YouTube Analytics
You will find statistics on YouTube in YouTube Studio under the Analytics menu. For a specific video, select Content, hover over the video and click Analytics. YouTube's help lists, among the available metrics, impressions, impression click-through rate, views, unique viewers, watch time, average view duration and number of subscribers (status as of October 2026, YouTube Analytics help
).
For engagement rate on YouTube, it is usually calculated using likes and comments relative to views, or possibly relative to unique viewers. The number of subscribers as a basis on YouTube says less, because a large share of views often comes from people who do not subscribe to the channel.
#### Statistics on TikTok
The numbers of views, likes, comments and shares are visible directly under each video. TikTok offers more detailed account and individual video statistics in the app; the exact name and location of this option changes between app versions, so please check it in TikTok's help or in your profile settings. On TikTok, the views-based formula makes the most sense, because most views usually do not come from followers.
### Why can't engagement rate be compared across platforms?
Figures from Instagram, TikTok and YouTube cannot be compared directly, because each platform defines views differently, offers different types of interactions and divides content between followers and non-followers in its own way. The same percentage therefore means something different on each network.
- Different definitions of views. Instagram counts views as the number of plays or displays of content, while YouTube, alongside views, also reports other metrics, such as "engaged views". The counts therefore arise under different rules.
- Different types of interactions. Saves, shares to a story or duets exist only on some networks, so the numerator is made up of different actions.
- Different formats. A short video, a photo in the feed and a twenty-minute video trigger different viewer behaviour.
- Different audiences. The share of followers and non-followers among viewers differs by network as well as by format.
Platforms also do not publish any official “average” or “good” engagement rate values. The figures circulating online come from different patterns and samples of accounts and may not apply to your profile. It is more sensible to set your own baseline.
### How can you tell whether your engagement rate is good?
The most reliable benchmark is your own: calculate the engagement rate of your recent posts using one formula and monitor what raises it and what lowers it. The procedure:
- Choose one formula for each network (we recommend reach or views) and do not change it.
- Record the interactions and the base for the last 10–20 posts, separately for each format (reels, photos, stories, short and long videos).
- Calculate the median for each format. This is your baseline.
- For new posts, note whether they are above or below the median and what distinguishes them (topic, length, first seconds, caption, time of publication).
- Recalculate the median once a month and track the trend, not individual fluctuations.
Looking at the structure of interactions also helps. Saves and shares usually indicate that the content has a value to the viewer that they want to keep or pass on, whereas a like requires less effort.

### How will buying followers or likes affect your engagement rate?
Buying followers increases the denominator, but on their own they usually bring no comments, saves or shares. The engagement rate calculated from followers therefore falls. Purchased likes, on the other hand, artificially raise the numerator, so the figure stops reflecting genuine audience interest.
For illustration, let us continue with the example: a profile with 2,000 followers and 150 interactions has a follower-based engagement rate of 7.5%. If 3,000 purchased followers are added and interactions remain at 150, the result is 150 ÷ 5,000 × 100 = 3%. The content has not changed, only the base has. The reach-based engagement rate is not directly affected, but it will not improve either. We describe how to recognise inactive and fake accounts among followers in the article how to recognise fake followers
.
It is also important to know that platform rules do not permit artificial inflation of interactions:
- Instagram the community guidelines state that likes, followers and shares must not be obtained artificially, and violations may result in deleted content, a blocked account or other restrictions ( Instagram community guidelines
, status as of October 2026).
- TikTok does not permit trading in services that artificially increase engagement, states that it removes fake likes and followers, and its sanctions include restrictions on visibility in the For You Page ( TikTok community guidelines
, status as of October 2026).
- YouTube under its policies on fake engagement, does not count subscribers flagged as spam or artificial views, and violations may lead to warnings, strikes or even channel termination ( YouTube policies on fake engagement
, status as of October 2026).
Restrictions on reach or on the account therefore cannot be ruled out after a purchase. This is explicitly stated also in terms and conditions
in Art. 3.3. Purchased interactions do not replace content, do not guarantee audience interest, sales or reach, and under the YouTube policies cited, subscribers flagged as spam are not counted in the total. They are therefore not a route to meeting monetisation requirements.
### When paid promotion makes sense and when it does not?
A package of likes or followers may serve as initial social proof for a new profile that already has quality content, or as a supplement to a specific campaign alongside your own work on content. However, always bear in mind that the engagement rate will no longer accurately reflect audience interest, and if you use it to assess content, it is better to monitor reach-based metrics.
Conversely, it makes no sense if content is still missing or weak, if you want to meet monetisation or verification requirements, if the account already has a warning or restriction, or if you expect sales and genuine responses from people. If you nevertheless decide to promote, you will find a description of the service on the page likes on Instagram
and current prices in price list
.
### Frequently asked questions
#### Do video views count towards engagement rate?
Usually not. Views serve as the base (the denominator) by which interactions are divided, not as an interaction themselves. The numerator normally includes likes, comments, saves and shares. If you added views to interactions, the result would be unrealistically high. Whichever variant you choose, use it consistently, otherwise the results will not be comparable.
#### What is a good engagement rate on Instagram?
Neither Instagram nor Meta publishes an official “good” benchmark, and the figures circulating online differ depending on the formula and the sample of accounts the author used. It is more useful to calculate the median engagement rate of your last 10–20 posts and track which formats and topics perform above it and which below it.
#### Should I calculate engagement rate based on followers or on reach?
For evaluating your own content, reach is more suitable, because it shows how many of the people who actually saw the post responded to it. Calculating based on followers is useful when comparing other profiles whose reach you do not know. Both figures are correct, but they answer different questions, so always state them together with the formula.
#### Why does my engagement rate fall even though I have more followers?
When the number of followers grows faster than the number of interactions, the ratio based on followers decreases. This may be caused by rapid growth due to a viral post or a contest, but also by followers who do not see your content or are not interested in it, including inactive or purchased accounts. Check whether the engagement rate based on reach is also falling. If it is not, the problem lies not in the content but in the basis of the calculation.
#### Can engagement rate be determined for someone else’s profile?
Only approximately. For another profile, you can see the public number of followers, likes and comments (unless the author has hidden them), but not the reach, saves or shares. You can therefore calculate only a simplified engagement rate based on followers, likes and comments. For comparison, use several posts and the same formula for all the profiles you are comparing.
