Engagement Rate Calculator

As rough bars, 1–3% is solid on most platforms, 3–6% is good, and above 6% is excellent, though small accounts routinely beat large ones, and TikTok runs well above Instagram or LinkedIn. Your own average is the benchmark worth beating: score every post the same way and hunt for the formats and topics that clear it.

Log each post's likes, comments, and shares in a Ferra table and you can ask which formats or topics run above your average.

Follower count, sample size, interaction total: that's everything the calculator needs. It returns average interactions per post and the rate as a percentage of followers, so accounts of any size land on the same scale.

Per-post first: divide total interactions by the number of posts. Then divide that average by followers and multiply by 100. Take an account with 15,000 followers whose 20 posts earned 6,000 total likes, comments, and shares.

6,000 ÷ 20 = 300 interactions per post. Then 300 ÷ 15,000 = 0.02, and 0.02 × 100 = 2%, on a typical post, 2 followers in every 100 interact.

Skip the per-post step and the number explodes: 6,000 ÷ 15,000 would read 40%, twenty times too high, because it bundles 20 posts into one. Mixing bases is the subtler slip: a rate calculated on reach is always higher than one calculated on followers, so the two can never be compared directly.

On follower-based math, 1–3% is commonly considered solid across most platforms and above 5% is strong. Below 1%, either the content isn't landing or the follower base has gone stale. Short-video feeds run higher than legacy social networks, so benchmark within a platform, never across platforms.

Size drags the rate down reliably, a niche account of 5,000 true fans out-engages a broad account of 500,000 casual followers. Watch your own trend hardest. A rate drifting down over months is an early warning that reach and relevance are slipping, well before the follower count shows it.

More of the followers who see a post have to act on it, that's the only way the rate moves. Prompts do the direct work; timing and format decide how many followers see the post at all.
