Engagement rate calculator

Which basis each platform is reported on. Instagram, Facebook and LinkedIn are normally measured against followers. TikTok, Reels, YouTube and Shorts are normally measured against views, because most of the reach on those comes from a recommendation feed rather than from your follower list. This calculator switches with the platform you pick, and it will not compare a view based rate to a follower based average, because that comparison is the most common mistake in social reporting.

How to calculate engagement rate: the formula

Engagement rate is one number: the share of an audience that did something with a post instead of scrolling past it. Add up the interactions, divide by the audience figure, multiply by 100.

Follower based: (likes + comments + shares + saves) ÷ followers × 100
View based: (likes + comments + shares + saves) ÷ views × 100

Worked example, follower based

An Instagram post on a 10,000 follower account picks up 400 likes and 30 comments. That is 430 interactions. 430 ÷ 10,000 = 0.043, and 0.043 × 100 gives an engagement rate of 4.3%.

Worked example, view based

A TikTok gets 50,000 views, 4,000 likes, 120 comments, 300 shares and 200 saves. That is 4,620 interactions. 4,620 ÷ 50,000 = 0.0924, so the engagement rate is 9.24%.

Followers based or views based

The two formulas answer different questions, and on the same post they can be several times apart, so the basis matters more than the decimal places.

• Divide by followers when you want to know how much of the audience you have already built is responding. This is the standard on Instagram, Facebook and LinkedIn, where most of the reach still comes from people who follow you.
• Divide by views when reach comes from a recommendation feed rather than from your follower list. This is the standard on TikTok, Reels and Shorts, and it is the only version that stays sensible when one video reaches twenty times your follower count.

A quick example of why it matters. A video on a 2,000 follower account gets 50,000 views and 4,620 interactions. View based, that is 9.24%. Follower based, the same post reads 231%. The second number is not wrong so much as meaningless, because the followers were never the audience.

The rule that keeps you honest: pick one basis, use it every time, and never compare a view based rate to a follower based one.

What each platform counts

These are the conventions the calculator follows. They are how each platform is usually reported, not rules the platforms set, so if your reporting template uses a different basis, switch the tool to match it.

Three of those rows are different enough to have their own version of this tool. TikTok reports engagement against views, so it gets its own calculator, with the follower switch kept for media kits that still ask for it. Instagram counts saves and shares, which changes the number more than most people expect on carousels and Reels. And YouTube and Shorts are measured against views too, with the two formats worth splitting rather than averaging.

What counts as a good engagement rate

One published average per platform, each with its source and the basis it was measured on. The calculator reads this same table, so when it gives you a verdict, you are being compared like for like: views against views, followers against followers.

One caveat before you compare. The Instagram and Facebook figures come from brand and business pages, and creator accounts run higher: HypeAuditor puts nano creators on Instagram at 2.19% (2024 data). If you post as a person rather than a brand, read those rows as a floor, not a par score.

LinkedIn is missing from the table on purpose. The one credible published average, 5.20% for 2025 (Socialinsider), is measured against impressions, and this calculator divides by followers, so printing it next to your number would be comparing two different sums. The LinkedIn figure worth having anyway: personal profiles average 63% higher engagement than company pages (Metricool, 2026). For a founder or an executive, that is the whole argument for posting as yourself instead of through the company page.

One warning about beating the average. It is a content metric, not a business one, and a rate that reads fine while nothing converts is a different problem. Plenty of accounts sit above par on engagement and below par on enquiries, because the audience enjoys the posts without ever being asked for anything.

How this calculator works

• Single post divides the interactions on one post by that post's audience number. Profile average takes your totals across a run of posts. On a view basis it divides total interactions by total views, so the number of posts does not change the answer and the tool does not ask for it. On a follower basis it divides your totals by the number of posts first, then by your follower count, which is the average post rather than the sum of a month.
• Optional fields left blank count as zero. If you cannot see saves on a post, leave the box empty rather than guessing, and say which fields you used when you report the number.
• Rates are rounded to two decimal places. Rounding is display only, the sum shown underneath uses the numbers you entered.
• Nothing is uploaded. The maths runs in your browser, there is no account, and no numbers are stored between visits.

For a founder or an executive, the rate is only half the question. The other half is whose attention it is, and positioning a founder so the engagement is worth having is a different job from getting the number up.
