How Missouri Child Support Calculation Works
Missouri child support calculations follow the Missouri Child Support Guidelines, which use a percentage of income model to determine support obligations. The calculation considers both parents' gross monthly income, number of children, custody arrangements, and additional expenses like work-related child care and health insurance.
Missouri Child Support Formula
Basic Obligation = Combined Income × Percentage1 child (20%), 2 children (28%), 3 children (32%), 4 children (35%), 5+ children (40%)Joint Custody: Basic Obligation × 0.90 (10% reduction)Missouri uses fixed percentages based on the number of children, making calculations straightforward and predictable. Joint custody arrangements receive an automatic 10% reduction in support amounts.
Key Factors in Missouri Calculations
Missouri child support calculations consider multiple factors to ensure fair and adequate support for children:
- Both parents' gross monthly income from all sources
- Number of children subject to the support order
- Custody arrangement (primary, joint, or split custody)
- Work-related child care expenses
- Health insurance costs for the children
- Other children living in either parent's household
- Joint custody automatic reduction (10%)
Missouri-Specific Considerations
- Percentage Model: Missouri uses fixed percentages rather than income sharesMakes calculations more predictable and straightforward
- Joint Custody Reduction: Automatic 10% reduction for joint custodyReflects shared parenting responsibilities
- Duration: Support continues until child reaches 18 or graduates high schoolWhichever occurs first, unless special circumstances exist
