Child Support If You Make $1,000 a Week in Louisiana
Louisiana math has three clean steps: combine, look up, and split. Here is exactly how $1,000 a week runs through each one.

Guideline child support scenarios at $1000 a week
The paying parent earns $1000 a week ($4,333.33 a month) in every cell below. The other parent's monthly income changes across rows, and the number of children changes across columns; both genuinely change the result.Every figure is computed with the real Louisiana guideline engine, the same one behind the full calculator, not a lookup table built for this page.
| Other parent's income | 1 child | 2 children | 3 children |
|---|---|---|---|
| No reported income | $818.00 | $1,251.67 | $1,521.67 |
| $2,000 a month | $737.35 | $1,125.53 | $1,363.63 |
| $4,000 a month | $641.68 | $977.43 | $1,182.48 |
| $6,000 a month | $586.82 | $884.14 | $1,057.89 |
Every dollar figure is a monthly amount, the presumptive guideline result before add-ons like child care or health insurance and before any court deviation. "Not available" means the engine behind this site declined to compute that specific combination rather than guess; the reason is shown next to it.
Three steps from income to a number
Louisiana first adds both parents adjusted gross income together to reach a combined figure. That combined figure is looked up on the R.S. 9:315.19 schedule, extrapolating between adjacent rows when the exact figure is not one of the 980 published amounts, to find a basic obligation for the number of children in the case. Finally, that basic obligation is split between the parents by their share of the combined income, and the nondomiciliary parent share becomes the support order under Worksheet A.
At $1,000 a week, the paying parent contributes about $4,333 a month to that combined total. The other parent income scenario in each table row adds to that figure before the schedule lookup runs, which is why the number changes row to row even though the paying parent side stays fixed.
Following one row through the three steps
Take the row where the other parent reports $4,000 a month. Combined income is $4,333.33 plus $4,000, or $8,333.33, which lands between two of the 980 official schedule rows and gets extrapolated between them per R.S. 9:315.13(B). That produces a basic obligation for the chosen number of children, and the paying parent share of the combined income, roughly 52 percent here, is applied to reach the final figure in the table.
What this estimate includes
- The full 2025 R.S. 9:315.19 schedule and its statutory extrapolation rule
- Worksheet A's income-share allocation for 1, 2, or 3 children
- The combined-income calculation from both parents
What it leaves out
- Net child care, health insurance, and extraordinary expense add-ons
- Worksheet B and split custody, which use different math
- Preexisting support paid to a non-party, which would reduce adjusted gross income
Worth knowing
The income-share step is what makes the other parent income genuinely change the Louisiana number, unlike Texas on this site, where the paying parent income alone drives the result. A Louisiana parent cannot assume their own number holds steady regardless of who they are paired with.
Louisiana Worksheet A also credits add-on amounts a parent pays directly, such as childcare paid straight to a provider, against that parent share of the total obligation, a step this simplified table leaves out since it depends on facts specific to each family.
Frequently asked questions
What are the three steps in the Louisiana formula?
Combine both parents adjusted gross income into one figure, look that figure up on the R.S. 9:315.19 schedule to find a basic obligation, and split that obligation between the parents in proportion to their share of the combined income. Worksheet A applies that split with the nondomiciliary parent as the presumptive payer.
What does "adjusted gross income" mean here?
Gross income minus any support actually paid under a preexisting order to someone who is not a party to this case, under R.S. 9:315(C)(1). Most parents without a prior support order will have adjusted gross income equal to plain gross income.
Does a higher other-parent income always raise the total obligation?
Usually, since the combined-income schedule generally rises with combined income. But it does not always raise the paying parent share, since a higher other-parent income also increases their share of the combined total, shifting some of that larger obligation onto them instead.
What is the extrapolation rule?
R.S. 9:315.13(B) expressly requires linear extrapolation, essentially interpolation, between the two adjacent official schedule amounts whenever combined income does not land exactly on one of the 980 published $50 increments.
Is $1,000 a week close to any schedule limit?
No. Combined with any of the other-parent scenarios on this page, totals stay well within the $1,050 to $50,000 range the 2025 schedule covers, so neither the below-floor gap nor the top-row rule applies at this income.
Where can I add a preexisting support deduction?
The full Louisiana child support calculator on this site has a field for support actually paid under a prior order to a non-party, which lowers adjusted gross income before the schedule lookup runs, a step this simplified table does not include.
About the numbers on this page
Every figure in the table above comes from running the real Louisiana child support engine on this site, the same engine and data pack behind the full Louisiana child support calculator. Nothing on this page is a separate estimate or a reimplementation of the math. See the sources below for the statutes and official worksheets behind the Louisiana guideline.
