Understanding Child Support in Missouri

Child support ensures a child’s financial well-being after parents separate or divorce, but calculating it can feel overwhelming. Missouri uses a structured formula, yet each case is unique depending on parental income, custody arrangements, and specific child needs.

As an experienced Missouri family law attorney, I help clients understand how support is calculated and ensure that the final order is both fair and accurate. This guide walks you through the process step by step. For related legal matters, you can also explore my firm’s Practice Areas, which include divorce, custody, and estate planning.

Missouri Child Support Guidelines

In Missouri, child support calculations follow the official guidelines set by the Missouri Supreme Court. These rules are designed to create equitable outcomes that meet the financial needs of children while reflecting each parent’s ability to contribute.

Income Shares Model

Missouri uses the Income Shares Model, which assumes that a child should receive the same share of parental income that they would have if the parents were living together. This model is widely used because it balances responsibility between both parents.

Combined Adjusted Gross Income

The process starts by determining each parent’s adjusted gross income (AGI) — including wages, bonuses, commissions, and other income sources. These figures are combined to form the total household income, which serves as the foundation for calculating child support.

Basic Child Support Amount

The combined adjusted gross income is cross-referenced with the Missouri Child Support Amount Chart to determine the basic child support amount. This chart considers the number of children and the combined parental income.

Determine Each Parent’s Percentage of Income

Each parent’s share of the total income determines their responsibility for the support amount. For example, if one parent earns 70% of the combined income, that parent would typically contribute 70% of the child support obligation.

Custody Adjustments

Custody arrangements can impact the total payment. Parents who have less than 36% of overnight custody often pay a higher portion, while those with more balanced time-sharing may see adjustments that reflect their caregiving contributions.

I’m a dedicated personal injury attorney based in the Ozarks of Southwest Missouri, committed to standing up for individuals who have been wronged or injured. Since 2017, I’ve focused my legal career on personal injury law—particularly automobile accidents and car crash cases—because I believe in fighting for those who are often overwhelmed by powerful insurance companies and complex legal systems. I graduated with high honors from the University of Arkansas William H. Bowen School of Law, where I had the privilege of serving as Chair of the Moot Court Board. That experience honed both my advocacy skills and my dedication to excellence in legal practice. Before opening my own law firm, I gained invaluable experience working closely with some of the largest insurance companies in the nation. That background now gives me an insider’s perspective on how insurance carriers operate—and I use that knowledge every day to level the playing field for my clients.
