Engagement Rate Calculator
Add up likes, comments, shares, and saves against your follower count — or your reach — to get an honest read on how a post actually performed.
Engagement rate
How engagement rate is calculated
Engagement rate is simply total interactions divided by an audience size, expressed as a percentage. The interactions are usually likes plus comments, often extended to include shares and saves since both signal stronger interest than a passive like. The audience size is where definitions diverge: dividing by followers gives a stable, comparable-over-time figure; dividing by reach gives a truer read on how the post that was actually shown to people performed.
Per-platform habits differ too — Instagram and TikTok audiences tend to comment and share more freely than, say, LinkedIn, so raw rates aren’t directly comparable across platforms. Use engagement rate to track a single account’s trend over time, or to compare accounts on the same platform and in the same niche.
Frequently Asked Questions
What's the difference between engagement rate by followers and by reach?
Engagement rate by followers divides interactions by your total follower count — it's the classic, most-cited version, comparable over time even as reach fluctuates with the algorithm. Engagement rate by reach divides interactions by accounts reached (how many people actually saw the post), which better reflects how that specific post performed. Report both when you can, and always say which one you mean.
What counts as a 'good' engagement rate?
It varies a lot by platform, niche, and follower count — smaller accounts typically see higher rates than huge ones. As a rough, commonly cited starting point: 1–3% is considered average on Instagram, TikTok often runs higher (5%+), and rates naturally trend down as an account gets bigger. Treat any single benchmark as a loose guide, not a rule.
Should shares and saves count as engagement?
Most current definitions include them alongside likes and comments, since platforms weight saves and shares heavily in their own algorithms — they signal stronger intent than a quick like. This calculator includes both as optional fields so you can match whichever definition a brand or report is using.
Why does my rate look different from what the platform shows me?
Native insights sometimes use a different denominator (reach instead of followers, or a rolling average across recent posts) or a different interaction set (e.g. excluding saves). If your number doesn't match, check which base the platform used and recompute here with the same one for a fair comparison.
Educational tool only. Figures are calculated from the numbers you enter and rounded for display — they are not pulled from any platform automatically, so double-check your inputs against your own insights.
