Understanding Mississippi's Child Support Formula
Mississippi uses the Percentage of Income model, one of the simpler child support approaches in the United States. The court converts the paying parent's gross monthly income to net income by applying a 76% factor that accounts for estimated taxes and mandatory payroll deductions. That net income figure is then multiplied by a fixed percentage that increases with each additional child:
| Children | % of Net Income | Monthly at $5,000 gross |
|---|---|---|
| 1 child | 14% | $532/mo |
| 2 children | 20% | $760/mo |
| 3 children | 22% | $836/mo |
| 4 children | 24% | $912/mo |
| 5 children | 26% | $988/mo |
Mississippi caps the paying parent's net income at $10,000/month for guideline calculations. A parent earning above approximately $13,158/month gross will have their obligation calculated from the cap rather than their actual income. Courts retain discretion to order additional support above the cap for high earners in cases involving extraordinary expenses.

Mississippi Child Support, Frequently Asked Questions
What percentage does Mississippi use for child support?
Mississippi uses 14% of adjusted net income for one child, 20% for two children, 22% for three, 24% for four, and 26% for five or more children. These percentages apply to the paying parent's net income after a 76% conversion factor for taxes.
Is there an income cap for child support in Mississippi?
Yes. Mississippi caps the paying parent's net income at $10,000/month (approximately $13,158/month gross) for guideline calculations. Income above this threshold does not increase the standard obligation. However, a judge can order additional support beyond the cap in cases where the child has extraordinary needs, such as private schooling, medical conditions, or significant extracurricular costs, or where the paying parent earns substantially more than the cap.
What is the average child support payment in Mississippi?
Child support awards in Mississippi typically range from $300–$700/month based on current data. The actual amount varies significantly depending on both parents' incomes, the number of children, custody arrangements, and whether costs like health insurance or childcare are included in the order. Higher income households and multiple children will produce awards above this range.
Can a Mississippi judge order a different amount than the calculator shows?
Yes. The Mississippi guidelines produce a presumptive amount — the starting point, but a judge can deviate from it when following the guidelines would be unjust or inappropriate in a specific case. Common reasons for deviation include extraordinary medical or educational expenses, one parent directly paying significant healthcare premiums, a parent's substantial assets or non-wage income, the needs of children from other relationships, or significant travel costs related to custody exchanges.
How do you modify a child support order in Mississippi?
Either parent can petition the Mississippi court to modify an existing child support order when there has been a substantial change in circumstances. This typically means a significant change in either parent's income (usually 15–20% or more), a change in custody or parenting time, the child developing extraordinary medical or educational needs, or a change in the cost of health insurance. Most states, including Mississippi, also allow automatic review every three years if either party requests it, even without proving a substantial change.
When does child support end in Mississippi?
In Mississippi, child support terminates at: Age 21 (among the highest termination ages in the US). The governing law is Miss. Code § 43-19-101, administered by the MDHS Division of Child Support Enforcement. If you have an existing order and believe your child is approaching the termination age, contact MDHS Division of Child Support Enforcement or your family law attorney to confirm the specific end date and ensure a formal termination order is entered.
