Commissions for RE Agents when buying homes from Builders

[Ambarish Vitta]

Hi all, 

I am a new agent in California and was looking at purchasing a New Home from Builders such as Toll Brothers, KB Homes, etc. 

This is a personal purchase for my family and primary residence. 

How much is the acceptable commission I can expect from the Builders. 

I keep getting different answers so thought will check with the community :) 

Much appreciated in advance. 

Regards,
