Engagement Rate Calculator
Enter your numbers once and see engagement rate by followers, reach and impressions — the three denominators people argue about.
Three denominators, three different numbers
- By followers — engagements ÷ followers. Easy to calculate from public data, which is why influencer marketplaces use it, but it punishes large accounts whose posts are shown to a fraction of their audience.
- By reach — engagements ÷ unique people who saw the post. The most honest measure of how compelling the content was, but only the account owner can see reach.
- By impressions — engagements ÷ total views, including repeat views. Always the lowest of the three.
A rate quoted without its denominator cannot be compared with anything. When a report says "4.2% engagement", the first question should always be: four percent of what?
What counts as an engagement
Likes, comments, shares and saves are normally included; video views usually are not, because a view is weaker than an intentional tap. Saves are worth watching closely — on Instagram and TikTok they correlate with the algorithm pushing content further, because they signal the viewer wanted to come back to it.
Benchmark ranges in 2026
- Instagram — 1-3% by followers is typical; under 1% on large accounts is normal, not a failure.
- TikTok — 4-8% is common because the For You page distributes widely.
- YouTube — engagement usually measured by likes per view; 3-5% is healthy.
- LinkedIn — 2-5% by impressions for personal posts; company pages run lower.
Why rate beats raw counts
A post with 500 likes on a 5,000-follower account outperforms one with 800 likes on a 200,000-follower account. Rate normalises for audience size, which is the only way to compare accounts, campaigns or creators fairly — and it is why engagement rate, not follower count, should drive partnership pricing.
