How is child support calculated in Missouri? (2026 Guidelines)
Missouri uses the Income Shares Model (Form 14). Both parents' incomes are combined to determine a basic child support obligation based on the number of children. This amount is then divided proportionally according to each parent's share of income. Finally, a parenting time adjustment reduces the paying parent’s obligation when they have significant overnight visitation (more than 90 overnights per year). Additional costs like health insurance and work‑related child care are added to the base support.
Missouri Form 14 Child Support Calculator – Key Factors
- Gross monthly income: Includes wages, bonuses, self-employment, unemployment, and imputed income if voluntarily unemployed.
- Number of children: Basic obligation increases with each child.
- Parenting time (overnights): More overnights = lower support (up to 50% reduction for equal custody).
- Add‑ons: Child care expenses, health insurance premiums, and extraordinary medical costs are split between parents.
2026 Missouri Child Support Guidelines Schedule (Basic Obligation)
The following table illustrates estimated monthly basic support for different combined incomes and number of children (based on Missouri’s Form 14 schedule). Actual amounts vary, but these reflect typical 2026 values.
| Combined Monthly Income | 1 Child | 2 Children | 3 Children | 4 Children |
|---|---|---|---|---|
| $4,000 | $752 | $1,073 | $1,276 | $1,468 |
| $6,000 | $1,021 | $1,487 | $1,805 | $2,094 |
| $8,000 | $1,272 | $1,880 | $2,302 | $2,684 |
| $10,000 | $1,513 | $2,249 | $2,770 | $3,241 |
Table based on Missouri Schedule of Basic Child Support Obligation (effective 2025-2026). For combined incomes above $20k, courts may apply formula beyond the schedule.
Missouri Child Support Calculator 50/50 Custody & Parenting Time
If parents share equal overnights (182.5 each), the support amount often still applies if incomes are unequal. Missouri uses a parenting time credit: the basic support is multiplied by a factor that reduces the paying parent’s share based on the percentage of overnights above 90. For 50/50 custody, the credit can lower support by up to 75% depending on income disparity, but it rarely eliminates support completely when one parent earns significantly more.
Many parents incorrectly assume that 50/50 custody means no child support. Wrong. In Missouri, the court still looks at incomes and then applies a parenting time adjustment. For 2026, using our calculator with equal overnights will show that the higher earner typically still owes a reduced amount. Always track actual overnights (not just “alternating weeks”) because every night counts.
Step-by-Step: How to Calculate Child Support in Missouri (Form 14)
- Calculate each parent's monthly gross income (include all sources, deduct prior child support paid for other children).
- Combine incomes → find the Basic Child Support Obligation from Missouri’s schedule based on # of children.
- Allocate proportionally → each parent’s percentage share of combined income.
- Add child care & health insurance costs (split proportionally).
- Apply parenting time adjustment → if the paying parent has more than 90 overnights, reduce support using Missouri’s formula (approx. 0.5% reduction per overnight over 90 up to max ~45% reduction).
- Result = presumptive child support amount (judge may deviate).
Additional Expenses & Missouri Child Support Calculation Worksheet
Missouri courts also consider:
- Work‑related child care – actual costs added to basic support and split by income percentage.
- Health insurance premiums – the parent providing coverage receives a credit; the other parent pays their share.
- Extraordinary medical/dental expenses – divided proportionally.
- Educational or special needs expenses – may be ordered in addition to guideline support.

Frequently Asked Questions – Missouri Child Support
Form 14 is the official worksheet used by Missouri courts to calculate child support based on income, parenting time, and expenses. Our calculator follows its methodology.
With true 50/50 custody, support may still be owed if incomes differ significantly. Missouri applies a parenting time adjustment that reduces the paying parent’s obligation based on overnights, but does not automatically zero out support.
Gross income includes wages, self-employment earnings, bonuses, commissions, tips, unemployment, and even certain fringe benefits like housing allowances.
Yes, a judge may deviate if the guideline amount would be unjust or inappropriate after considering factors like extraordinary medical costs or educational expenses.
Overnights are the nights the child stays with a parent. They directly affect the parenting time adjustment — more overnights reduce the support obligation.
For very low income, a minimum monthly order of around $50–$100 may apply, but the court uses discretion.
Guidelines are reviewed periodically; the current schedule remains in effect for 2026 with the 2025 updates.
3 costly mistakes Missouri parents make
1. Forgetting to include overtime/commission: Missouri includes all regular income. Hiding bonuses can lead to retroactive support.
2. Not adjusting for overnights when custody changes: A 70/30 split vs 60/40 changes support significantly. Always recalc Form 14.
3. Assuming child support covers everything: Health insurance, extracurriculars, and uninsured medical costs are usually separate add-ons.
