* Percent of Income Model: Illinois utilizes the percentage of income formula which determines the amount of child support as a percentage of the income of the parent obligated to pay the child support. This percentage is determined by factoring the number of children requiring support. This is the most basic or primitive method for calculating support. Many people believe that it does not take into consideration many important details, which makes this model of support calculation the least exact.
