What is GCI?

Gross Commission Income (GCI) is the total commission earned from all real estate transactions in a given period — before any deductions. It represents your gross revenue contribution, before your brokerage takes its split or any other fees are applied.

GCI is the most fundamental metric in a real estate agent's business. It determines tax obligations, drives income forecasts, and is the basis for calculating every other performance metric.

Formula
Sale Price × Commission Rate = GCI
Example: $700,000 × 3% = $21,000 GCI

Annual GCI — a worked example

For a full year or quarter, GCI is the sum of all commissions earned across every transaction you closed in that period. Both buyer-side and seller-side transactions count separately — each represents its own commission income.

Worked Example
Closed transactions18 deals
Avg. sale price$566,666
Avg. commission rate (per side)2.5%
Total transaction volume$10.2M
Annual GCI$255,000

Why GCI is not the same as income

A common mistake is treating GCI as take-home income. In reality, GCI is gross revenue. From this number, several deductions reduce what the agent actually keeps:

Gross Commission Income
$200,000
Brokerage split (20%)
−$40,000
Per-transaction fees
−$5,800
Monthly desk fees (annualised)
−$3,600
Business expenses
−$40,000
Pre-Tax Net Income
~$110,600

An agent earning $200,000 GCI may net $110,000–$130,000 before tax. Understanding the gap between GCI and net income is essential for informed business planning.

Why GCI matters for forecasting

GCI is the input for every meaningful projection an agent needs. Your year-end income forecast, quarterly tax estimate, financial runway calculation, and pipeline valuation all start from GCI. Without accurate, real-time GCI tracking, all downstream metrics are unreliable.

💡

Key insight: Tracking GCI monthly against seasonality-adjusted expectations gives the clearest signal of whether you're ahead of or behind your annual goal — before a slow quarter turns into a financial problem.
