How North Dakota calculates child support
North Dakota uses the percentage of income model: child support is calculated as a set percentage of the paying parent's income, with the percentage increasing with the number of children.
Governing law: N.D. Admin. Code ch. 75-02-04.1; N.D.C.C. § 14-09-09.7 — Obligor-only net-income schedule (custodial parent's income largely ignored); guidelines amended on a four-year cycle, most recently effective Sept 1, 2023.
North Dakota publishes an official calculator that applies the full guideline schedule: official North Dakota child support calculator. Use ours for a quick, private estimate and theirs when you need the exact worksheet figure.
Frequently asked questions
How is child support calculated in North Dakota?
North Dakota uses the percentage of income model: child support is calculated as a set percentage of the paying parent's income, with the percentage increasing with the number of children. The guideline is set by N.D. Admin. Code ch. 75-02-04.1; N.D.C.C. § 14-09-09.7.
Is this the exact amount a North Dakota court will order?
No — this is a guideline estimate. Courts start from the guideline amount but can deviate for factors like extraordinary medical costs, special needs, other support obligations, or agreements between parents. For an official figure, use the state’s own calculator linked on this page or consult a family law attorney.
Does parenting time affect child support in North Dakota?
In most states, including under most guideline models, substantial parenting time (often above roughly 20–30% of overnights) reduces the paying parent's obligation. Our calculator applies a simplified parenting-time adjustment; North Dakota's courts apply their own specific rules, so treat shared-custody results as rough estimates.
What income counts for child support in North Dakota?
Generally all income: wages, self-employment, bonuses, commissions, and often investment income. North Dakota's guideline applies to net (after-tax) income — our calculator approximates net income from the gross figures you enter. Courts may also impute income to a parent who is voluntarily unemployed or underemployed.
