How child support is calculated in North Dakota
North Dakota looks up child support in a schedule using only the paying parent’s monthly net income (rounded to the nearest $100) and the number of children; the other parent’s income is not part of the basic calculation. Adjustments apply for more than 100 overnights of parenting time and for equal residential responsibility.[1]

The rules behind North Dakota’s numbers
The guideline is N.D. Admin. Code § 75-02-04.1-10. Open each rule to read the exact words.
- Income counted
Obligor’s net income (gross minus hypothetical taxes and other listed items)
Support is based on the paying parent’s net income: total gross income minus a hypothetical federal and state income tax and other listed deductions, converted to a monthly figure.[1]
Official text · N.D. Admin. Code § 75-02-04.1-01(6)
“"Net income" means total gross annual income less:”
- Percentages
Income rounded to the nearest $100 before using the schedule
Monthly net income is rounded to the nearest $100 before the schedule is applied, and dollar results are rounded to the nearest whole dollar.[1]
Official text · N.D. Admin. Code § 75-02-04.1-02(5)
“In applying the child support guidelines, an obligor's monthly net income amount ending in fifty dollars or more must be rounded up to the nearest one hundred dollars, and must otherwise be rounded down to the nearest one hundred dollars.”
- Top of the guidelines
Top row: $25,000+ net/month = $3,500 (1 child) to $6,500 (6+ children)
The schedule tops out at monthly net income of $25,000 or more, where the amounts are $3,500, $4,250, $5,000, $5,500, $6,000 and $6,500 for one through six or more children.[1]
Official text · N.D. Admin. Code § 75-02-04.1-10 (schedule)
“25000 or more 3500 4250 5000 5500 6000 6500”
- Low income
$800 or less net/month = $0 in the schedule
The schedule shows no support for monthly net income of $800 or less; at $900 it starts at $90 for one child.[1]
Official text · N.D. Admin. Code § 75-02-04.1-10 (schedule)
“800 or less 0 0 0 0 0 0 900 90 126 171 198 234 261”
- Shared parenting time
Extended parenting time: more than 100 overnights a year
If the paying parent has court-ordered parenting time of more than 100 overnights a year, the amount is reduced per child by a formula using 0.32 times that child’s overnights.[1]
Official text · N.D. Admin. Code § 75-02-04.1-08.1
“For each child, multiply the number of that child's parenting time overnights times .32 and subtract the resulting amount from three hundred sixty-five.”
- Shared parenting time
Equal residential responsibility: each parent’s amount computed, then offset
When parents have equal residential responsibility, an obligation is calculated for each parent as if the other had primary residential responsibility, and the smaller is subtracted from the larger.[1]
Official text · N.D. Admin. Code § 75-02-04.1-08.2
“The lesser obligation is then subtracted from the greater. The difference is the child support amount owed by the parent with the greater obligation.”
