Engagement Rate Calculator

How to use this calculator

The engagement rate formula is one line: interactions ÷ audience × 100. Add up the interactions on a post — likes, comments, shares and saves — divide by the audience number you are measuring against, and multiply by 100 to turn it into a percentage.

Worked through with real numbers: 390 likes, 42 comments and 18 shares is 450 interactions. On an account with 10,000 followers that is 450 ÷ 10,000 × 100 = 4.50%. That is the calculation every tool on the internet performs, and on its own it is close to useless — because "the audience number" is a decision, not a fact. Swap followers for reach and the same post can read two, three or five times higher. The calculator above runs the sum six ways at once and prints the spread, so you can see how much of your result is the denominator rather than the content.

If you want the formulas explained rather than executed — including the per-platform variations and the mistakes that quietly inflate a media kit — read how to calculate engagement rate, and see where the metric sits among the social media KPIs that actually matter.

What this calculator counts as an engagement

Before you divide, you have to agree on what goes on top of the fraction — and the platforms do not agree with each other. This matters more than it sounds, because the benchmark you compare yourself to counted specific interactions and nothing else.

• Instagram — likes, comments, shares and saves. The benchmark band on this page counted likes + comments / followers, so if you add saves and shares to your numerator you are measuring something slightly more generous than the benchmark did.
• TikTok — likes, comments, shares and saves, divided by views. TikTok is the one platform where the industry denominator is not followers, and it is the single most common mistake in spreadsheets: dividing TikTok interactions by follower count and comparing the result to a per-view benchmark.
• LinkedIn — divided by impressions, which LinkedIn reports natively and which is why its benchmarks are built on them. The reference band is published as engagement / impressions without itemising the interactions, so check what your own analytics view is counting before you compare.
• Facebook — reactions, comments and shares against page fans. Organic Facebook engagement is structurally low, so a number that would look alarming on Instagram can be completely normal here. If yours is flat, the fix is usually format and prompt rather than volume — see Facebook engagement posts that actually get replies.
• YouTube — interactions / subscribers, again without the interactions itemised. Treat this one gently: the reference study published a single median rather than a range, so there is less to lean on here than on the other platforms.

Text posts on X have their own quirk, since the character budget shapes how much room a post has to earn a reply at all — our Twitter character counter is the quickest way to check a draft against the limit before you publish it.

Which of the six results should you report?

There are six in common circulation, and each one answers a different question. The calculator computes all of them, but this is when to quote which.

• By followers — the rate-card standard. Use it in a media kit or when you are being compared to other accounts, because it is the only formula an outsider can compute about an account they do not own.
• By reach — the fairest read on a single post. Reach counts unique accounts that actually saw it, so it measures the content instead of penalising you for dormant followers.
• By impressions — always the lowest of the set, because impressions count repeat views. Use it on LinkedIn, where the published benchmarks are built on impressions.
• By views — the video denominator, and the basis of TikTok benchmarking. Views are not unique accounts, so this is not interchangeable with reach.
• By posts — interactions ÷ (followers × posts). Averages a batch so one viral outlier does not define the account. This is the number to put in a monthly report.
• Daily — interactions ÷ (followers × days). Worth using when you post several times a day and a per-post figure stops meaning anything.

One rule covers all six: name the one you used. An engagement rate quoted without its denominator is a number nobody can check, and when you receive one in a pitch deck it is reasonable to ask.

How your result compares to platform benchmarks

Here are the bands the calculator judges you against, with the denominator attached to each one — because putting these five numbers in a single column without it is how the internet convinced everyone that LinkedIn engagement is ten times better than Instagram's.

Sources: Instagram, TikTok, LinkedIn and Facebook bands from Socialinsider; YouTube from the Quid (formerly Rival IQ) 2026 Social Media Industry Benchmark Report. Figures last verified 2026-09-24. No platform publishes an official engagement benchmark, so all five are independent studies of public posts rather than authoritative rates.

Engagement rate is measured differently on every platform — per follower on Instagram and Facebook, per view on TikTok, per impression on LinkedIn. Compare like with like or the comparison is meaningless.

Two more things worth knowing before you treat a band as a target. First, these are medians: account size, niche and format move them, and smaller accounts usually engage better than large ones, so a benchmark drawn from hundreds of thousands of profiles is a starting line rather than a grade. Second, YouTube's figure is the weakest of the five — the study published one median and no range at all, so we show it as a single number rather than dressing it up as a band.

If your rate has fallen off a cliff rather than drifted, the cause is usually mechanical: a format change, a posting-time change, or reach suppression on a specific account. Our guide to telling a real Instagram shadowban from an ordinary slump walks through how to distinguish the two before you start deleting posts.

The platforms nobody benchmarks

Threads, Pinterest and Bluesky are missing from every engagement rate calculator we could find, including the big ones — and rather than quietly dropping them, this tool lets you calculate a rate and then tells you there is nothing credible to compare it to.

Threads reports views, likes, replies and reposts in Insights, so the arithmetic works; there is simply no sampled study of Threads engagement in our sourced reference yet. Pinterest breaks the model differently: a Pin keeps accumulating impressions and saves for months, so a rate measured a week after publishing understates it and one measured a year later flatters it — always state the window. Bluesky has the hardest problem: its public post records expose likes, reposts, replies and quotes, but no impressions or reach at all. Any per-impression Bluesky engagement rate you see published has been reverse-engineered rather than measured, which is why per-follower is the only honest denominator there.

Turning the number into a report

A rate on its own rarely survives a client meeting. What travels is the rate plus the denominator plus the comparison, in one sentence — which is why the calculator emits a copy-paste line naming the formula it used, the band it compared you to, the sample that band came from and the date the figures were verified. Paste it straight into a deck and the number is defensible.

For the rest of the report, our free social media report template gives you the structure, and the social media KPIs guide covers the eleven other metrics worth reporting alongside engagement rate. Other free calculators and checkers worth bookmarking: the UTM builder for attributing the traffic your posts send, and the banned hashtag checker for ruling out the dumbest cause of a reach drop.

One reason to get the denominator right: your engagement rate is the number brands price against. As a cross-check, sponsored Instagram posts are commonly valued at a CPM of roughly $5 to $25 — the estimate is published as "USD per 1,000 followers/impressions reached" by Influencer Marketing Hub, an independent estimate rather than a Meta-published rate, and it moves with niche and audience country. A rate calculated against impressions when the buyer assumed followers is the difference between a fair fee and an awkward conversation.

From measuring engagement to earning it

Calculating the rate takes seconds. Moving it is the work: posting consistently, in the format each platform currently rewards, at a time your audience is actually awake. That is what Outfeed AI is for. It is a chat-first AI social media manager — you describe the post, it writes it in your brand voice, shows a per-platform preview, and schedules and publishes to Instagram, TikTok, LinkedIn, Twitter/X, Facebook, Threads, YouTube, Pinterest and Bluesky from the same conversation.

Starter is $29 a month and Pro is $59 a month, and both are flat rather than per seat — unlike Hootsuite and Sprout Social, which bill per seat from their entry tier. Outfeed AI only charges per seat at the Agency tier, at $149 per seat per month, with Enterprise priced on request. The free trial runs 3 days and includes 100 AI credits; a card is required to start it.
