How the math works

Tier 1 = min(value, threshold) × t1 rate. Tier 2 = value above threshold × t2 rate. Total + bonus.

Tiered commission structures align broker incentives on large deals without overpaying. A 4/2.5 tier structure on a $15M deal costs $450k vs $600k flat — $150k savings that can instead fund a price bonus or shorter-timeline bonus tied to outcomes that matter.
