If the agent has hit their cap, the brokerage keeps only the flat fee and the effective split jumps toward 100%.
The math, in plain terms.
Gross commission income (GCI) is the sale price times the commission rate. On a $450,000 sale at 3%, that's $13,500 before anyone is paid.
The brokerage's pre-cap share is GCI times one-minus-the-agent-split. But most modern brokerages use an annual cap: once an agent has paid the brokerage a set amount for the year, the agent keeps the rest (minus any flat per-transaction fee). This calculator applies the cap, so the deal where an agent “caps out” shows the take-home jumping.
The effective split is the agent's take-home divided by GCI — the number that actually matters to a recruit deciding between brokerages, and the number a broker-owner needs to model when setting cap and fee structure.
Questions, answered.
What is a real estate commission cap?
A cap is the maximum an agent pays the brokerage in split commissions per year. After the agent reaches it, they keep 100% of GCI (minus any flat transaction fee) until the year resets.
How do I calculate effective split after the cap?
Divide the agent's actual take-home for the year by their total GCI. Early-year deals sit near the nominal split; once capped, each additional deal pushes the effective split toward 100%.
Is this calculator tax advice?
No. It models gross commission mechanics for planning only — it does not account for taxes, MLS/board dues, E&O, or team splits. Verify your own numbers.
