How is Child Support Calculated in Illinois?

October 31, 2024

In Illinois, child support is based on the incomes of each parent and the amount of parenting time allocated to each parent. Parenting time will generally only impact child support if the non-majority time parent has 146 (or more) overnights per year. This amounts to about 40% of the time. Less than 146 overnights per year will usually not affect the amount of child support. Other factors can affect child support include, other children in your household, paying child support for another child, the amount of taxes you paid, or health insurance costs for the child at issue.


The Illinois Department of Healthcare and Family Services provides an online calculator to help you calculate child support. It can be found at https://hfs.illinois.gov/childsupport/parents/childsupportestimator.html


At Mitchell Highlander, LLC, we recommend hiring an experienced child support attorney to assist you with determining the correct child support calculation for your family.
