How is the Interstate Pay Differential Calculated?
To adjust for differences in costs of living in various locations around the country, simply enter the two letter postal designator for the state in which each parent resides. (e.g. KS for Kansas, MO for Missouri, etc.) A list of the designators appears in the “drop down” window for each parent. The Child Support Calculator will automatically look up the Average Annual Pay value for each state and compute the ratio between each state and Kansas, expressing the ratio as a percentage in the data input area. It also computes and displays the child support income value of each parent in Kansas-equivalent dollars, and uses the IPD adjusted income in the child support calculations. The Average Annual Pay value for each state is obtained from the data published by the Bureau of Labor Statistics. The program is updated whenever new data is published.
