Child Support in Mississippi: How It's Calculated
Mississippi uses the Percentage of Income Model to determine child support obligations. This guide walks through how the formula works, what factors Mississippi courts consider, and how to modify or enforce an order — with links to official Mississippi resources.
Percentage of Income Model in Mississippi
Mississippi uses a Percentage of Income Model under §43-19-101. Only the adjusted gross income of the paying (non-custodial) parent is used. A fixed percentage is applied based on the number of children.
Mississippi percentages are: 1 child — 14%, 2 children — 20%, 3 children — 22%, 4 children — 24%, 5 or more children — 26% of adjusted gross income. Mississippi courts may deviate from these amounts when applying the guidelines would be unjust, inequitable, or not in the child's best interest, and courts must make written findings to justify any deviation.
Key Factors Mississippi Courts Consider
- Non-custodial parent's adjusted gross monthly income
- Number of children
- Any extraordinary expenses for the child
- Child's health insurance costs (may be ordered separately)
- Significant parenting time by the non-custodial parent (basis for potential deviation)
- Special needs of the child
- Economic circumstances of either parent that would make the guideline amount unjust

Step-by-Step: How Mississippi's Formula Works
Here is how Mississippi applies the Percentage of Income Model to calculate a child support obligation, step by step:
1. Determine the paying parent's income
Mississippi applies its formula to the paying (non-custodial) parent's income. Mississippi percentages are: 1 child — 14%, 2 children — 20%, 3 children — 22%, 4 children — 24%, 5 or more children — 26% of adjusted gross income.
2. Apply the state's percentage to income
A fixed percentage is applied based on the number of children. 1 child — 14%, 2 children — 20%, 3 children — 22%, 4 children — 24%, 5 or more children — 26% of adjusted gross income
3. Add health insurance and childcare if applicable
In Mississippi, health insurance premiums for the child and work-related childcare costs may be added to the base support amount or ordered separately, depending on the specific statute.
4. Apply parenting time adjustments
If the paying parent exercises significant parenting time, Mississippi may reduce the obligation. Significant parenting time by the non-custodial parent (basis for potential deviation)
5. Apply income caps and deviation factors
Mississippi may cap the income subject to the percentage, and courts can deviate from the guideline amount with written findings that the formula result would be unjust or inappropriate.
