Joshua is correct. It is a potential Sherman anti-trust violation for Realtors to discuss, or recommend what is and is not standard, normal, usual, "going", regular or any other type of commission. Each agent and agency charges what they think their market will bear, and what they believe their services are worth. Period.
from our local board's website regarding anti-trust guidelines:
At any time, in any place, or under any circumstances, do not have any personal, telephone or e-mail conversations with competitors concerning commissions, fees, charges or any other business practices of your real estate business or those of the firm with which you are associated. This applies at social gatherings, on the golf course, while hunting, in the bar, cocktail parties, board functions and at all times and in all places. At association or board meetings, confine discussions to topics of association or board business directly involved in the purpose of the organization and the meeting.
I have seen commissions range anywhere from 0% up to 12% or even higher depending on the circumstances. The best thing you could do for youself is to interview as many agents as possible and ask them all what they charge. This will give you your best answer.

While Joshua's answer is mostly true, don't panic. In this area I've never seen commissions approaching anywhere near 12%. Feel free to contact me if you need any assistance.
Commission rates are not set. They are negotiable. They usually run at about 6% of the sale's price and is split evenly between listing brokerage and buying brokerage. But remember the listing agent has quite some work getting your property in order and having all the paperwork and inspections done. Then of course you have the 'open houses' and all the advertisements. And if you offer less than 3% to the buying agent sometimes your home is not as often viewed as others that offer 3%.
Hope this will help you in your decision.
