A real estate commission is a fee that is paid to a real estate agent for their services in helping to buy or sell a property. The commission is typically a percentage of the sale price of the property and is split between the buyer's agent and the seller's agent.

For example, if the commission rate is 6%, and the property sells for $300,000, the total commission would be $18,000, with $9,000 going to the buyer's agent and $9,000 going to the seller's agent. This means that if you are buying a property that is selling for $300,000, your agent would receive a commission of $9,000 for helping you to buy that property.

Another example, if the commission rate is 4%, and the property sells for $500,000, the total commission would be $20,000, with $10,000 going to the buyer's agent and $10,000 going to the seller's agent. This means that if you are buying a property that is selling for $500,000, your agent would receive a commission of $10,000 for helping you to buy that property.

As a buyer, you typically do not pay the commission directly, it is usually included in the purchase price of the property. This means that, the seller of the property is paying the commission, not the buyer.

It's important to note that commission rates can vary depending on the region, the type of property, and the real estate agent or brokerage. Some agents may charge a higher commission rate than others, so it's important to ask about commission fees when interviewing potential agents.
