Each quarter during the year the Bureau of Labor Statistics releases updated average wage information. The Bradley Kansas Child Support Calculator uses this updated wage information to calculate the interstate pay differential (IPD). The IPD is used to offset the cost of living difference between where a parent reside and Kansas wage equivalence. In effect this equalizes a wage paid in a state other than Kansas with Kansas average wages.
An example of this might be where one parent lives in Kansas who has a monthly income of $2000 and the other parent living in New York state who has a monthly income of $4000. The cost of living in New York state is vastly different than the cost of living in Kansas. Using the latest data released on Feb 20th, 2019 (for 3rd Quarter 2018) the average weekly wage in Kansas is $867. Where the average weekly wage in New York is $1272.
Per the Kansas Child Support Guidelines section III.B.9 (also Appendix IV), these values are used to compute an adjustment in the wages for the parent living in New York. The guidelines state:
To compute the Interstate Pay Differential, develop a value by dividing the average weekly wage in Kansas (KS) by the weekly wage of the new state.
This value is then taken times the wage of the parent living in the new state. So in our example for the parent living in New York the formula is:
(KS avg wage) / (NY avg wage) * (Income of Parent living in NY) = KS equivalent wages
(867) / (1272) * (4000) = $2726
$2726 is the Kansas equivalent wages for the parent residing in New York.
The Bradley Kansas Child Support Calculator has been updated for the latest BLS data update that was released on Feb 20th, 2019. The Bradley Program is updated each time the new data is released, typically within days of that release.
