The formulas this calculator uses
There is no single official engagement rate. Each platform shows different counts, so the formula changes by platform. This tool uses these common versions:
- Instagram: (likes + comments) ÷ followers × 100
- TikTok, by views (main result): (likes + comments + shares) ÷ views × 100
- TikTok, by followers (second result): (likes + comments + shares) ÷ followers × 100
- YouTube: (likes + comments) ÷ views × 100
TikTok shows views on every video and much of its reach comes from people who do not follow the account, so the per-view figure is usually the more useful one. The per-follower figure is shown for comparison with Instagram-style reports. Saves and shares on Instagram, and dislikes on YouTube, are not counted because they are not shown publicly on every post.
A worked example
An Instagram post with 450 likes and 50 comments on an account with 10,000 followers: (450 + 50) ÷ 10,000 × 100 = 5.00%. A YouTube video with 900 likes, 100 comments and 20,000 views: (900 + 100) ÷ 20,000 × 100 = 5.00%. The same percentage on two platforms does not mean the same performance, because the bases (followers vs views) are different.
How to read your result
We do not publish benchmark percentages, because published figures vary widely by source, sample, niche and date. A few patterns hold in general:
- Smaller accounts often show a higher rate than very large accounts, because the follower base grows faster than interaction.
- Per-view rates and per-follower rates are not comparable. Compare like with like.
- One post says little. Average 10 or more recent posts for a steadier picture.
- The most useful comparison is your own account over time, or accounts of a similar size in the same niche.
Purchased metrics change the inputs, not the audience. If you add followers or views, the engagement rate may go down unless interaction grows too. Read the Instagram SMM panel guide for what purchased metrics can and cannot do.
Frequently asked questions
What is engagement rate?
Engagement rate is the share of people, measured as followers or views, who interacted with a post through likes, comments or shares. It is shown as a percentage.
Which TikTok formula does this calculator use?
The main result is (likes + comments + shares) ÷ views × 100. A second result divides the same total by followers, for comparison with follower-based reports.
Why does YouTube use views instead of subscribers?
Many YouTube views come from people who are not subscribed, and views are shown on every video, so a per-view rate reflects the actual audience of that video better.
Is my data sent anywhere?
No. The calculation runs in your browser. Nothing is submitted, stored or tracked, and you do not need an account.
What is a good engagement rate?
It depends on platform, niche, account size and the formula used, so we do not quote a single number. Compare your result with your own past posts or with similar accounts, using the same formula.
Does buying likes or views raise my engagement rate?
Adding likes raises the numerator; adding followers or views raises the denominator and can lower the rate. Purchased metrics do not guarantee reach, sales or real audience interest.
