How Missouri Calculates Child Support

Missouri uses a specific worksheet known as Form 14 to determine child support. This calculation is based on the Income Shares Model, factoring in each parent’s gross income, custody time, and various expenses.

Key components of the calculation:

  1. Gross monthly income of both parents

  2. Adjustments for other child support or spousal maintenance

  3. Health insurance and childcare costs

  4. Number of overnights each parent has

  5. Credits for court-ordered payments or equal time parenting

Our calculator automates the Form 14 worksheet to give you a clear estimate in just minutes.

Parenting Time and Form 14 Credits

Parenting time directly affects child support in Missouri. Parents who have significant overnight time or equal custody may qualify for Form 14 credits that reduce the child support obligation.

  • Over 109 overnights often results in a support credit

  • Equal parenting time (50/50) can result in even larger adjustments

  • Courts review custody arrangements to ensure fair calculation
