Child Support If You Make $1,000 a Week in Idaho
Idaho does not bill the paying parent for the whole marginal obligation. It splits it by each parent share of combined income, and at $1,000 a week the payer is the majority earner.

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 Idaho 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 | $662.00 | $995.00 | $1,167.00 |
| $2,000 a month | $606.89 | $899.74 | $1,058.47 |
| $4,000 a month | $541.84 | $801.84 | $953.68 |
| $6,000 a month | $482.26 | $717.10 | $864.71 |
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 the share split works
Idaho first applies its marginal schedule to the combined annual Guidelines Income of both parents, producing a combined obligation for the number of children. Then it assigns each parent a share of that obligation equal to their share of the combined income. The paying parent owes their share, not the full schedule figure.
At $1,000 a week the payer brings $4,333.33 a month, which exceeds every other-parent scenario below $6,000 a month, so the payer carries more than half of the combined income in most rows. That means the payer share of the marginal obligation stays above half as well, while the other-parent rows still move the dollar figure through the combined schedule.
Reading the split across the rows
Every row uses the same $1,000-a-week payer income. The combined marginal obligation rises as the other-parent income grows, but the payer percentage share of that combined total falls. The figure in each cell is the product of those two forces, which is why the movement across the rows is not a straight line.
What this estimate includes
- The Rule 120 marginal schedule for the combined income
- The proportional assignment of the obligation to each parent
- The payer as the majority earner across most other-parent scenarios
What it leaves out
- A flat-percentage formula, which Idaho does not use
- The below-$800 individualized review, not reached at this income
- Add-ons such as child care and health insurance
Worth knowing
The proportional split is the same mechanic every income shares state uses, but the marginal schedule it splits is Idaho own published structure.
Because the payer is the majority earner in most rows, the payer figure stays substantial even at the higher other-parent scenarios, a useful real-world point for a parent earning $1,000 a week.
Frequently asked questions
Does Idaho split child support 50/50 between the parents?
No. Idaho assigns each parent a share of the combined marginal obligation equal to their share of the combined income. A parent earning more than half of the combined total owes more than half of the obligation.
Why does the number change across the other-parent rows?
Each row changes the combined income, which changes both the marginal obligation and the payer percentage share. Two things move at once, so the change is not a simple straight line.
Is the payer always the majority earner at $1,000 a week?
In most rows, yes. The payer brings $4,333.33 a month, and only the $6,000-a-month other-parent scenario approaches or exceeds it. Below that, the payer share stays above half.
What is the combined obligation based on?
It is the sum of the Rule 120 marginal band amounts applied to the combined annual Guidelines Income, using the rate for the number of children in the case.
Does the marginal structure affect the split?
The marginal structure sets the combined obligation; the split then divides that obligation proportionally. The two steps are separate, and both matter to the final figure.
What would the number look like if the other parent outearned the payer?
The payer share of the obligation would drop below half, and the payer would owe a smaller slice of a combined obligation that is also larger. That case is not among the rows shown here.
About the numbers on this page
Every figure in the table above comes from running the real Idaho child support engine on this site, the same engine and data pack behind the full Idaho 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 Idaho guideline.
