Which child support calculator should I use?

2011 Calculator: Use the 2011 child support calculator for all child support orders entered after May 31, 2011, whether they are original orders or modifications of pre-existing orders, unless the court determines otherwise based on good cause shown. In case of default, the guidelines in effect at the time of filing the action will be used. The parties may agree to use either the guidelines in effect at the time of filing the action or those in effect at the time the order is entered.
