Child Support Calculations in Illinois

During the course of a marriage and afterwards, you may be expected to support your spouse both emotionally and financially.  Whereas that might be debatable, there is a clear legal obligation to care for any children from that marriage.

Part of that care is to contribute money for the well-being of the children through child support.  These funds are meant to provide for basic needs such as shelter, food and clothing.  At the court’s discretion, the payer may also be ordered to provide additional funds for expenses related to childcare, education, extracurricular activities as well as medical and dental costs.

There is a basic formula which provides the framework for child support payments based on the payer’s net income and the number of children being supported.  The following percentages are the minimum amount of child support which can be ordered.

Number of Children Percentage of Net Income













It is a percentage of net income because some deductions are taken out before calculating child support.  Net income in this case will generally equal gross pay minus state and federal income tax, FICA payments, union dues, health insurance premiums, and prior child support obligations.

The previous information is summarized on a Uniform Order of Support after the final support payment is decided by the divorce court.  It will include the rate of payments, payee information, penalty for late support payments, and an end date for the support.  If you have a question about your current child support agreement or are investigating filing for divorce, contact an experienced divorce attorney in DuPage County today.
