With child care and health insurance
North Dakota's guideline amount doesn't add child care costs.
| Costs | Guideline amount |
|---|---|
| No add-ons | $875 a month A→B |
| Child care $500 a month | $875 a month A→B |
| Child care $1,000 a month | $875 a month A→B |
| Health insurance $150 a month | $875 a month A→B |
| Health insurance $300 a month | $875 a month A→B |
Child care and extraordinary costs aren't added by formula. The children's health insurance premium and ongoing medical expenses a parent pays are subtracted from that parent's net income.
Things to know about this example

How North Dakota works it out
North Dakota applies a schedule to the paying parent's monthly net income and the number of children; the other parent's income isn't used. Net income is rounded to the nearest $100 before the schedule is applied.
Net income is gross income less a hypothetical federal income tax for a single filer with the standard deduction, a hypothetical state income tax of 11% of that federal tax, Social Security and Medicare, and what the parent pays for the children's health insurance and ongoing medical expenses. These taxes are set by the guidelines, not taken from a tax return.
When a court order gives the paying parent more than 100 overnights a year, each child's share is reduced in proportion to those overnights. With equal residential responsibility, an obligation is worked out for each parent and the smaller is subtracted from the larger.
