When a property is sold, a brokerage firm typically earns 3% of the sales price. For example, if a broker sells a house to a buyer for a sale price of $600,000 the firm would earn $18,000. The amount the broker would earn would be dependent on the agreement between the firm and the broker. Some brokerages will give 100% of the commission, all $18,000 to the broker, subject to a small transaction fee and a monthly desk fee, while others will split the commission with the broker at various percentages 50/50, 70/30 etc. There are many different commission structures offices will use as well as varying levels of service and training provided to the broker.
