How are real estate commissions calculated and split between the listing broker, selling broker, and agents?

Topic: Real Estate Math Updated: April 2026
Quick Answer

Commission is typically calculated as a percentage of the sales price (e.g., 6%). The total commission is split between the listing broker and selling broker (often 50/50 or 60/40). Each broker then splits their portion with their agent (often 80/20 or 70/30 depending on the agent's experience). Commission rates are negotiable and not set by law.

Real Estate Math on the Real Estate Exam

Understanding commission math is essential for agents calculating their earnings, brokers managing revenue, and all parties understanding transaction costs. Commission calculation problems appear on all state exams. This is practical knowledge agents use every day.

What It Means

Real estate commissions are the fees paid for brokerage services. The commission is typically expressed as a percentage of the sales price and is negotiable between the seller (who typically owes the commission) and the broker. A common commission rate is 6% of the purchase price, though this varies widely and is entirely negotiable. The listing agent and broker negotiate a commission split in their broker agreement; the selling agent and broker negotiate separately. Commission splits are not mandated by law.

The typical commission flow in a standard transaction is: (1) Seller owes 6% of the $400,000 purchase price, which equals $24,000. (2) This $24,000 is split between the listing broker and the selling (buyer's) broker, often 50/50, though the split may be 60/40 or other arrangements. Assume 50/50: each broker receives $12,000. (3) The listing broker splits the $12,000 with the listing agent, perhaps 80/20 (more experienced agents get higher percentages): the listing agent gets $9,600 (80% of $12,000). (4) The selling broker splits the $12,000 with the selling agent, perhaps 70/30: the selling agent gets $8,400 (70% of $12,000).

Commission structures vary widely. A new agent might receive 50/50 or 60/40 to the broker; an experienced agent might receive 90/10 to the broker or even 100% if the broker charges a monthly desk fee. The listing side and selling side do not have to use the same split. Some brokers charge graduated commissions based on transaction volume or agent experience. Some brokers take additional fees for transaction processing, administrative services, or market analysis. Agents must understand their specific broker's commission splits and fee structure.

In transactions with multiple agents or brokers (such as double-ended transactions), commission may be split among more parties. In a FSBO (for sale by owner) transaction, the buyer's agent may negotiate their commission directly with the buyer or may not receive commission at all. Agents must be able to calculate their net earnings after all splits and must ensure they understand their broker's commission structure before closing transactions.
