Understanding Gross Commission Income (GCI)
Gross Commission Income (GCI) is the single most vital metric for real estate agents, commercial brokers, financial advisors, and sales teams. It measures the top-line commission dollars generated by transactions before any internal splits, team payouts, or operating overhead expenses are subtracted.
Gross Commission Income Formula
GCI measures gross performance prior to downstream revenue share allocations:
Gross Commission Income (GCI) = (Gross Transaction Revenue − Client Returns/Deductions) × (Commission Rate / 100)How to Calculate GCI Step-by-Step
- Determine Total Revenue: Sum up gross sales prices across closed transactions.
- Subtract Adjustments: Deduct customer returns, allowances, or freight adjustments.
- Apply Contracted Percentage: Multiply commissionable sales by your contractual rate.
Numerical Calculation Example:
A real estate agent sells a property for $600,000 with $10,000 seller concessions and a 5% listing commission:Commissionable Sales = $600,000 − $10,000 = $590,000.GCI = $590,000 × 0.05 = $29,500.00.
