To use the child support calculator, select or enter the appropriate information next to each statement.

When you have completed the form, click on the calculate button to get an estimate of the amount of child support that the non-custodial parent will have to pay to the custodial parent in Missouri.

Disclaimer: Please remember that these calculators are for informational and educational purposes only. The amount of child support a court will order for any particular case may be different from the amount estimated by the calculator.

For the most part, these calculators assume that all of the children at issue will primarily live with one parent. They are not intended to estimate child support for joint physical custody or split custody arrangements.

These calculators do not take into account any possible adjustments for children who are not subject to the custody order, but who are living with one of the parents. Finally, these calculators may be based on older or outdated state guidelines or calculations and may not take into consideration state or federal tax implications on income.

These and many other factors can affect a child support order entered by a court.

Missouri Child Support

Missouri child support is handled by the Child Support Enforcement (CSE) program which is a division of the Missouri Department of Social Services. They offer a number of services to eligible families that need assistance with matters related to child support.

How to apply for support through CSE

Determining your child support payment
There are many factors involved in calculating your monthly child support payment. Missouri child support state guidelines include:  how many children need support, the income of both parents, cost of health care and day care, etc.

Enforcing child support orders
The CSE can help ensure that the non-custodial parent fulfills his or her support obligations. CSE can help enforce your order by: income withholding, intercepting tax refunds, reporting delinquent payors to the credit bureau, ordering employers to enroll non-custodial parents’ children in health care plans, placing liens on personal or real property, suspending licenses, intercepting lottery winnings, and requesting Contempt of Court or criminal Non-Support charges.

Because there are 23 CSE field offices throughout Missouri, you can find a CSE office located near you whether you live in Columbia, Independence, Lee's Summit, Springfield, Kansas City, St. Louis, or elsewhere in the state. For more information about Missouri child support please visit
