Earning $200,000 in net commission income per year depends on average home prices and brokerage commission splits, but assuming a standard 3 percent agent commission on a 50/50 split with a brokerage, an agent needs roughly $13.3 million in total closed sales volume. For homes averaging $1.0 million, an agent would need to sell approximately 13 to 14 houses annually, whereas lower-priced regional markets require a significantly higher transaction volume.
