Engagement Rate Calculator
Calculate social engagement rate against followers, reach, or impressions — three genuinely different, clearly-labelled formulas, not one universal one.
Common on Instagram/TikTok — measures engagement relative to your total audience size, regardless of who actually saw the post.
Both values must be whole numbers.
The same post produces three different engagement rates depending on what you divide by — followers, reach, and impressions are never equal, so switching the formula changes the result even though nothing about the post's actual performance changed. There is no single "correct" engagement rate formula across platforms; pick the one your platform or team actually uses, and state it explicitly when reporting the number.
Calculated entirely in your browser — nothing you enter here is sent to a server.
Social engagement rate has no single universal formula — it depends entirely on what you divide total engagements (likes, comments, shares, saves) by. This tool supports the three common denominators separately — followers, reach, and impressions — because they measure genuinely different things and produce different results for the exact same post.
There is no universal benchmark for what counts as a "good" engagement rate — it varies enormously by platform, audience size, content format, and industry, so this tool shows only the calculation, not a judgment of the result.
