How is child support calculated in North Dakota?
North Dakota applies a percentage-of-obligor-income model. The non-custodial parent typically pays a set percentage of gross or net income that scales with the number of children, and the exact percentages vary by state — see the statutory rates listed above for North Dakota. The custodial parent's income is generally not factored.
The calculation typically adjusts for: (1) work-related childcare, (2) the child's portion of health-insurance premiums, (3) extraordinary medical expenses, and (4) parenting time when overnights cross a state-defined threshold (e.g., 20%–40% depending on jurisdiction). Pre-existing support orders for other children, alimony paid, and mandatory retirement contributions also reduce gross income before the formula applies.
Guideline figures are presumptive — judges may deviate upward or downward when applying them would be unjust given the child's needs, the parents' resources, or other relevant factors. North Dakota courts retain final discretion. Always confirm the current guideline tables and worksheet with the North Dakota child support agency or family court.

North Dakota uses the Income Shares model under NDAC 75-02-04.1, with the Child Support Guidelines table reviewed every four years (most recent 2024 cycle). ND has unique provisions for "split parenting" when each parent has primary custody of different children, and a "shared parenting" formula when each parent has at least 35% parenting time. The Department of Human Services Child Support Division administers approximately 30,000 cases.

North Dakota child support — frequently asked questions
How is child support calculated?
Most states use the income shares model, which estimates what parents would have spent on the child if they lived together, then divides that based on each parent's income share. Factors include gross income, number of children, custody arrangement, and healthcare/childcare costs.
Can child support be modified?
Yes. Either parent can request a modification if there is a substantial change in circumstances, such as a significant income change (increase or decrease), job loss, change in custody arrangement, or changes in the child's needs.
At what age does child support end?
In most states, child support ends at age 18 or high school graduation (whichever comes later). Some states extend support to age 19-21 or through college. Court orders may specify different end dates based on individual circumstances.
