How It Works

Real Estate Commission Structure

Real estate commissions are negotiable fees paid at closing, typically by the seller, for the services of real estate agents.

How Commission Splits Work

1. Total commission is set in the listing agreement (typically 4-6%) 2. The listing brokerage offers a co-op split to the buyer brokerage (often 50/50) 3. Each brokerage splits with their agent based on the agent-broker agreement

Recent Changes

After the 2024 NAR settlement:

  • Buyer agent compensation is no longer advertised on MLS
  • Buyers may negotiate and pay their agent directly
  • Commission rates are more openly negotiated

    • Commission as a Selling Cost

    Commission reduces your net proceeds and is factored into capital gains calculations as a selling expense, lowering your taxable gain.

    Worked Example

    A $450,000 sale with 5% total commission, 50/50 split. Both agents have 70/30 splits with their brokerages.

    sale_price = 450000total_commission_pct = 5listing_agent_split = 50listing_agent_broker_split = 70buyer_agent_broker_split = 70
    1. 01Total commission: $450,000 x 5% = $22,500
    2. 02Listing side: $22,500 x 50% = $11,250
    3. 03Buyer side: $22,500 - $11,250 = $11,250
    4. 04Listing agent (70% of side): $11,250 x 70% = $7,875
    5. 05Buyer agent (70% of side): $11,250 x 70% = $7,875
    6. 06Each brokerage keeps: $11,250 x 30% = $3,375
