How Louisiana Calculates Child Support

Louisiana calculates child support using the Income Shares Model as defined in LA R.S. §9:315. Both parents' adjusted gross incomes are combined to determine the total support obligation from the state schedule, then each parent's share is allocated proportionally based on their percentage of the combined income. Louisiana uses net income (after deductions) as a key consideration in the calculation.

The calculation begins by determining each parent's adjusted gross monthly income from all sources. These incomes are combined, and the state schedule is used to find the basic support obligation for the number of children involved. Health insurance premiums and childcare costs are added to the base obligation, and adjustments are made for shared custody plans, extraordinary expenses, and the self-support reserve of $1,012 per month.

Low-income obligors may qualify for a reduced obligation under Louisiana guidelines. Courts may also deviate from guideline amounts when justified by the specific circumstances of the case, including the child's special needs or extraordinary medical expenses.
