ONE FORMULA, EVERY PLATFORM

Same three numbers, different story per platform

Engagement rate is one formula — (likes + comments) ÷ audience × 100 — but what counts as good differs sharply by platform. Pick yours, type three numbers, and read the result against that platform's own benchmarks. Runs in your browser, no signup.

Average your last 10-12 posts, skipping the one viral outlier and the one flop — a steady sample beats a flattering one.

Free and unlimited — the numbers never leave your browser.

The formula: (likes + comments) ÷ followers × 100. The by-views variant divides by average views instead — same interactions, different denominator. Both are averages over your recent posts, so feed them the same sample of posts.

Different tools use different engagement inputs — the manual calculator above uses likes + comments. The TikTok profile lookup adds public shares and divides by plays. Typical bands below apply only to the method named in each row:

PlatformTypicalStrongRate convention
Instagram1-3%3-6%(Likes + comments) ÷ followers
TikTok2-5%5-10%Here: (likes + comments) ÷ followers. Profile lookup: (likes + comments + shares) ÷ plays
YouTube1-5% of engaged views5%+ of engaged views(Likes + comments) ÷ engaged views — not subscribers

A note on the YouTube row: on 24 August 2026 YouTube changed what counts as a view, and the public number now includes people who saw only the first frame. Divide by that and your rate comes out lower than it really is — use engaged views from YouTube Studio → Analytics → Advanced mode instead. Rates measured before that date and after it are not comparable unless both use engaged views. Instagram and TikTok are unaffected.

Going deeper on your platform? The Instagram page adds follower-based brand-screening context. The TikTok page instead reports visible interactions per 100 public plays. For YouTube, the Money Calculator and Monetization Checker work in its native views-based currency.

01

Pick the platform

A 3% rate is strong on Instagram and merely solid on TikTok — same math, different typical bands. The calculator switches benchmarks when you switch platforms, so the verdict is honest for where you actually post.

02

Average your recent posts

Take rough averages of likes and comments over your last 10-15 posts, skipping the viral outlier and the flop. Consistency of sample matters more than precision — you're measuring a trend, not a moment.

03

Use the platform page for depth

Each platform's dedicated calculator page goes deeper: what brands screen for, why rates drop, and what moves the number. This page gets you the answer; those pages get you the context.

The three engagement rate formulas, and which one a brand will use

There is no single definition, and the same account scores very differently under each. When a brand quotes your engagement rate back at you, this is which one they meant.

How the three common formulas differ.
FormulaDivided byUsed when
By followersTotal followersThe default in most media kits and the one most calculators report
By reachAccounts reachedThe fairest to accounts whose posts travel beyond their followers
By viewsVideo viewsIncreasingly standard for short-form video, where most viewers never followed you

All three are in active use across the industry; none is official. What matters in a negotiation is agreeing which one you are both quoting before you compare numbers.

Why your engagement rate falls as you grow

It is almost never that the content got worse. A larger following contains more people who followed once for one post and never came back, and the algorithm shows any single post to a smaller share of a big audience than of a small one. This is why comparing your rate against a much larger account tells you nothing, and why brands compare accounts within a size band rather than across them.

Why the same numbers mean different things per platform

A 2% rate is unremarkable on TikTok and strong on Instagram, because the platforms distribute content differently — TikTok pushes videos to people who never followed you, Instagram mostly does not. That is why this calculator asks which platform you are measuring rather than returning one universal verdict, and why a media kit that quotes a single blended engagement rate across platforms tells a brand less than it thinks.

Frequently asked questions

How do you calculate engagement rate?

The standard formula: (average likes + average comments) ÷ followers × 100, averaged over recent posts. The by-views variant divides by average views instead — same interactions, different denominator. Brands screen with the follower version; creators diagnose content with the views version. This calculator gives both.

What is a good engagement rate?

It depends on the platform, and comparing across platforms is the classic mistake. Community benchmarks put typical Instagram accounts at 1-3% by followers and typical TikTok accounts at 2-5% — TikTok runs structurally higher because full-screen video and one-tap likes make engaging cheaper. Judge each account against its own platform's bands.

Why is there no YouTube mode here?

Because YouTube's engagement math is genuinely different: the industry convention divides by video views, not subscribers — subscriber counts on YouTube say little about who actually watches. Rather than print a subscriber-based band no benchmark supports, YouTube has its own page: the YouTube Engagement Rate Calculator reads a channel's recent public videos and gives likes plus comments per 100 views, against bands for that channel size.

Engagement rate by followers or by views — which should I use?

Both, for different jobs. By-followers is the screening metric — it's what anyone can compute from your public profile, so it's what brands use to compare accounts. By-views measures how compelling the content was to people who actually saw it, which matters most on feed-driven platforms where views can dwarf followers.

Do Facebook and LinkedIn use the same formula?

The same structure — interactions ÷ audience × 100 — with each platform's own interaction types (reactions, shares, clicks). The benchmarks differ again: LinkedIn's typical rates run below 2%, Facebook pages often below 1%. The formula on this page travels; the verdict bands don't.

Why is my engagement rate dropping?

Usually arithmetic before crisis: follower growth outpacing reach (denominator grew), a format shift the audience hasn't followed yet, or a posting-cadence change. Check whether absolute likes and comments are still climbing — a falling rate with rising absolutes is growth, not decay.

Is this engagement rate calculator free?

Free, unlimited, no username, no signup — the numbers never leave your browser. There's no profile scan behind it: just the arithmetic, the platform's benchmarks, and an honest read.
