Home sellers often feel resentful about paying realtor commission, but research shows that using a real estate agent can help them increase the profit they make by nearly $50,000 more on average than sellers who don't.

The top five states in this ranking have an average realtor commission rate of 6.04%. The average total commission on a $300,000 home in these states is $18,114.
