Child support is determined by using a program used by the courts called the Dissomaster program. To figure out how much someone will pay in child support, the court needs to know how much each parent makes gross per month (before taxes). After inputting those numbers for the parents, the court then needs to input the timeshare percentage between the parents (how much time per week each parent is getting – 50%, 25%, etc.). After adding some deductions, this program will spit out a number that the court will use to determine child support.
