Mississippi Child Support Calculator

Mississippi uses the Income Shares Model, which is the most common approach in the United States. This model considers both parents’ incomes to determine what they would likely spend on their children if living together. Some states use the Percentage of Income Model (like Texas), while others use the Melson Formula (like Delaware). The Income Shares Model is generally considered the most equitable as it accounts for both parents’ financial situations.

Mississippi courts consider gross income from all sources, including wages, salaries, commissions, bonuses, dividends, severance pay, pensions, interest, trust income, annuities, capital gains, Social Security benefits, workers’ compensation benefits, unemployment insurance benefits, disability insurance benefits, and recurring gifts. Overtime pay and secondary employment income are also typically included.

When parents share joint physical custody (each has the child for at least 35% of overnights), Mississippi applies a “shared parenting adjustment.” This reduces the basic support obligation because each parent is directly covering expenses during their parenting time. The calculator accounts for this by applying an adjustment factor based on your custody arrangement selection.

Yes, child support orders can be modified when there’s a “material change in circumstances.” This typically means a 20% or greater change in the support amount, significant income changes for either parent, changes in the child’s needs, or changes in custody arrangements. Modifications require filing a petition with the court that issued the original order.

Child support systems vary widely globally. In the United Kingdom, the Child Maintenance Service uses a formula based on the paying parent’s gross income. Canada uses Federal Child Support Guidelines with provincial variations. Australia considers both parents’ incomes, care percentages, and child costs. Germany uses a “Düsseldorfer Tabelle” with income-based tables. France calculates based on both parents’ resources and child needs. Japan determines amounts based on the payer’s income and number of children.

Mississippi has several enforcement mechanisms for unpaid child support: income withholding, tax refund interception, license suspension (driver’s, professional, recreational), credit bureau reporting, contempt of court proceedings, liens on property, and passport denial. The state can also secure judgments for arrears and charge interest on past-due amounts.

Uninsured medical, dental, and vision expenses that exceed $250 per child per year are typically considered “extraordinary medical expenses.” These are divided between parents in proportion to their incomes and added to the basic child support obligation. The calculator includes a field for these expenses to provide a more accurate estimate.
