Illinois brokerages ranked by agents

The twenty largest brokerages in Illinois by agents with a published profile, with the brand behind each and, where the brand publishes one, its national pay plan in short.

How to read this

Size is not quality, but it is information. The biggest brokerage in Illinois, RE/MAX with 2,147 agents, has the most colleagues to learn from and the most competition for leads inside its own walls. A brokerage with 25 agents in the state can mean more attention and more room.

What you keep is the number that matters, and most brands do not publish it. Franchise networks set splits office by office, so two offices of the same brand across town can differ. In Illinois, Fathom Realty publish a national plan; the rest are shown as "set by each office". Take the offer you actually receive, put it in the commission calculator next to the published plans, and compare at your own volume.

Agents with their own website tend to carry their business with them; a brand's rate is shown on its head-to-head pages.
