Child Support If You Make $750 a Week in Illinois
The same $750-a-week paycheck converts to a different net-income figure depending on which parent the state table assumes has the majority of overnights.

Guideline child support scenarios at $750 a week
The paying parent earns $750 a week ($3,250.00 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 | $593.63 | $893.77 | $1,072.53 |
| $4,000 a month | $532.44 | $797.77 | $948.74 |
| $6,000 a month | $481.28 | $715.86 | $845.10 |
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.
Why the conversion table has two columns
The 2026 Gross to Net Income Conversion Table Illinois publishes under 750 ILCS 5/505 lists two net-income figures for every gross-pay row, not one. One column assumes the parent has the majority of parenting time and can claim certain tax benefits that come with it; the other assumes they do not.
This page uses the non-majority column, the more common starting point for a paying, non-custodial parent. A parent who does hold the majority of overnights and is still the one paying support, a less common but real arrangement, would see a different net-income figure and a different result than the table below shows.
How to read the table below
Every row uses the same $750-a-week gross pay for the paying parent, converted through the non-majority-parenting-time column. 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 in either column.
What this estimate includes
- The 2026 Gross to Net Income Conversion Table, non-majority parenting-time column
- The income shares schedule of basic obligations for 1, 2, or 3 children
- Honest refusals where the published table does not cover a combination
What it leaves out
- The majority-parenting-time column figure, since it applies to a different case type
- Court-ordered support paid for children of other relationships
- Maintenance (spousal support), computed separately under 750 ILCS 5/504
Worth knowing
A parent unsure which column applies to their real filing status can ask a court to use an individualized net-income calculation instead of either standard column.
The two-column structure exists because Illinois standardized deductions include an assumption about which parent claims the dependency-related tax benefits, and that assumption changes with parenting time, not with income.
Frequently asked questions
What is the difference between the two columns in the conversion table?
The majority-parenting-time column assumes the parent claims tax benefits, such as head-of-household filing status, that come with having children the majority of overnights. The non-majority column assumes they do not. The same gross pay converts to a different standardized net income depending on which column applies.
Which column does this page use?
The non-majority parenting-time column, since the more common case for a paying, non-custodial parent is not holding the majority of overnights. A parent who does hold majority parenting time and still pays support would see the other column 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, in both columns. A parent reporting $0 falls below what the published table covers, so this page shows that honestly rather than inventing a figure.
Does my actual tax filing status change the result more than the table column does?
A parent can ask a court for an individualized net income calculation based on real taxes instead of either column of the standard table, and the result can differ from both. This page always uses the published non-majority column, the version most paying-parent cases use.
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.
Does the parenting-time column choice affect the schedule lookup too?
Indirectly. The column changes each parent net income, and the combined net income of both parents is what gets looked up on the schedule of basic obligations, so a different column choice can shift which schedule bracket applies, not just the deduction amount.
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.
