Engagement Rate Calculator with Measured Platform Benchmarks

Most engagement calculators hand you a number and a shrug — "1–5% is normal". That is unusable: the normal band differs several-fold by platform. This one compares your result against quartiles we measured across 50,000+ creators and tells you which band the account sits in on its own platform.

Measured quartiles by platform (peak-post metric)

Metric note: the quartile table uses peak-post engagement ÷ followers — the only metric we can measure uniformly across the whole index. It runs naturally higher than averages, so enter the creator's best recent post when comparing. Full analysis and tier breakdown: the benchmark study.
