Child Support If You Make $500 a Week in Illinois
$500 a week is well above the income where Illinois switches to a flat minimum order, but close enough that the floor is worth understanding before reading the table below.

Guideline child support scenarios at $500 a week
The paying parent earns $500 a week ($2,166.67 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 Illinois 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 | Not available: the Illinois gross-to-net conversion table does not cover this monthly gross income; adjust the income values above | Not available: the Illinois gross-to-net conversion table does not cover this monthly gross income; adjust the income values above | Not available: the Illinois gross-to-net conversion table does not cover this monthly gross income; adjust the income values above |
| $2,000 a month | $410.65 | $624.12 | $754.04 |
| $4,000 a month | $393.86 | $593.98 | $711.78 |
| $6,000 a month | $347.76 | $520.95 | $619.76 |
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.
How close $500 a week comes to the minimum-order floor
Illinois sets a hard floor under its income shares formula. When the paying parent gross income is at or below 75 percent of the federal poverty guideline for one person, currently $997.50 a month, the court applies a rebuttable minimum order of $40 a month per child, capped at $120 total, instead of running the standard schedule.
$500 a week works out to $2,166.67 a month gross, more than double that floor, so the minimum order does not apply here and the table below runs the ordinary income shares math. A parent whose gross pay is closer to $230 a week would be the one to check this page family lower income levels against the floor instead.
How to read the table below
Every row uses the same $500-a-week gross pay for the paying parent, converted through the real 2026 table, not the minimum-order shortcut. The other parent income and the number of children both genuinely move the result, since Illinois combines both parents net incomes before splitting the obligation proportionally.
The "no reported income" row is marked unavailable rather than guessed, because the published conversion table itself does not list a net-income figure for a $0 gross parent; this page never substitutes an assumption the table does not provide.
What this estimate includes
- The 2026 Gross to Net Income Conversion Table lookup for both parents
- The income shares schedule of basic obligations for 1, 2, or 3 children
- A check of this income against the 505(a)(3.3a) minimum-order floor
What it leaves out
- The minimum-order calculation itself, since this income does not trigger it
- Court-ordered support paid for children of other relationships
- Maintenance (spousal support), computed separately under 750 ILCS 5/504
Worth knowing
The minimum-order floor is tied to the federal poverty guideline, so it moves each year as that federal figure updates, independent of any change to the income shares schedule itself.
A party can rebut the minimum order with evidence, meaning even a parent under the floor is not guaranteed the flat $40-per-child amount; a court can still apply the standard calculation if the facts support it.
Frequently asked questions
Does $500 a week trigger the Illinois minimum order?
No. The minimum order applies only when the paying parent gross income is at or below $997.50 a month, 75 percent of the one-person federal poverty guideline. $500 a week is $2,166.67 a month gross, well above that line, so the ordinary income shares schedule applies instead.
What is the Illinois minimum order, for comparison?
When it does apply, 750 ILCS 5/505(a)(3.3a) sets a rebuttable minimum of $40 a month per child, capped at $120 a month total regardless of how many children are in the case. A party can rebut the minimum with evidence the standard calculation should apply instead.
Why is the "no reported income" row unavailable?
The 2026 Gross to Net Income Conversion Table lists standardized net-income figures starting at a defined gross floor. A parent reporting $0 falls below what the published table covers, so this page shows that honestly rather than inventing a net-income figure the table itself does not provide.
Does my actual tax situation change the result?
Not under the standard table used here. A parent can ask a court for an individualized net income calculation based on real taxes instead of the table, and the result can differ from the table figure shown on this page.
Why does the number change with the other parent income?
Illinois income shares support combines both parents net incomes into one total, finds the basic obligation for that combined amount and the number of children, then splits it in proportion to each parent share of the combined income.
Is $500 a week considered low income for Illinois child support purposes?
It is on the lower end of what the standard schedule covers, but it is not "low income" in the specific statutory sense that triggers the minimum order. That designation is reserved for gross income at or below the $997.50 monthly poverty-based floor.
About the numbers on this page
Every figure in the table above comes from running the real Illinois child support engine on this site, the same engine and data pack behind the full Illinois 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 Illinois guideline.
