The rate is (Reactions + Comments + Shares) divided by page followers, times 100. The follower-based version is the industry standard for comparing accounts; the alternative denominator measures content performance among people who actually saw it and typically reads 2 to 5x higher.
Engagement rates fall as accounts grow, so the verdict compares you against your follower tier, not the whole platform. A nano creator at 1.5% to 3.0% is performing normally; the same number from a mega account would be exceptional.
Verdicts step at the band edges: at or above 120% of the band ceiling reads Excellent, above the midpoint Good, inside the band Average, under half the floor Low.
The brand deal figure multiplies your follower count by a per 1,000 base of $5 to $15, then by the same engagement band and niche multipliers the sponsorship calculators use, so the two tools always agree.
