Adjusted Gross Income

Formula Description

Louisiana combines both parents' adjusted gross incomes and takes the basic child support obligation from the statutory schedule in La. R.S. 9:315.19. Each parent then pays a percentage share equal to their portion of the combined adjusted gross income.

Rates & Multipliers

Set by the statutory schedule, not by flat percentage. Amounts vary by combined adjusted gross income and number of children.

Income Caps

Where combined income falls between two schedule amounts, the obligation is extrapolated. Where it exceeds the highest level in the schedule, the court sets the amount, but not below the highest schedule figure.

Disclaimer: This is an informational estimate based on standard guidelines. Actual court calculations may differ based on judicial discretion, specific deductions, and unique family circumstances.

Louisiana Guidelines

State-Specific Formula

Louisiana applies the Income Shares Model under La. R.S. 9:315 et seq. Both parents' adjusted gross incomes are combined, the basic obligation is drawn from the schedule in La. R.S. 9:315.19 by combined income and number of children, and each parent pays a proportional share.

Important Disclaimer

The schedule amount carries a rebuttable presumption of correctness. A court may deviate only after finding the guideline amount would not serve the child's best interest, and written reasons are required under La. R.S. 9:315.1.
