How Louisiana calculates child support
Both parents' incomes are added together, the state's schedule gives the support a child would get if the parents lived together at that combined income, and each parent pays their share in proportion to their income. Most income shares states then adjust for health insurance, child care and, often, parenting time.
Use the official Louisiana calculator
Louisiana's schedule and adjustments are long and change when the state reviews its guidelines, so the most reliable estimate comes from the state's own tool: Louisiana DCFS: child support worksheet.
What you will need
- Both parents' gross monthly income.
- The number of children in the case and any other children either parent supports.
- Monthly cost of the children's health insurance and work-related child care.
- The parenting-time schedule (overnights per year).
