Realtors are paid commission based on the price of the home they sell. Generally, in every real estate transaction there are two Realtors that must split the commission, the buyers agent and the sellers agent. A standard commission percentage is 6%. So on a 100,000 house there will be $6,000 commission earned. But this commission must be split between the two agents who generally must split a portion of that commission with their broker. So, if each agent gets half of the $6,000 or $3,000 and then must split 30% of that to the broker, the agent would gross $2100 before expenses. As you can see the amount an agent earns can vary, but top agents can earn six figures or more.
