How child support is calculated in North Dakota
North Dakota uses the Percentage of Income Model, which bases child support on a percentage of the paying parent's income. Only the paying parent's income is used — the receiving parent's income is not considered in the base formula.
North Dakota uses an official dollar-amount table (not a flat percentage) based on the obligor's monthly net income. Example amounts:
| Net income/mo | 1 child | 2 children | 3 children |
|---|---|---|---|
| $1,500 | $342 | $416 | $491 |
| $3,000 | $590 | $846 | $1,007 |
| $5,000 | $907 | $1,415 | $1,691 |
| $10,000 | $1,699 | $2,838 | $3,402 |
| $25,000+ | $3,500 | $4,250 | $5,000 |
Source: N.D. Admin. Code § 75-02-04.1-10 (effective July 1, 2023). Full table applies to net income; this calculator approximates net income as ~75% of gross.
Shared custody, parenting time credits, and when to modify
Custody percentage has a direct impact on child support in North Dakota. As the non-custodial parent's time with the child increases, their direct child-rearing costs increase — and the support obligation is adjusted downward accordingly. Most states, including North Dakota, apply a parenting time credit or schedule adjustment when custody approaches or exceeds a certain threshold.
Modifications to existing orders in North Dakota generally require a "substantial change in circumstances" — typically a 10–20% change in income, a significant change in custody time, or a major change in the child's needs. Courts don't automatically update orders; either parent must file a motion. Use this calculator to model what a new order might look like before filing.

North Dakota uses an official dollar-amount table based on the obligor's monthly net income and number of children (N.D. Admin Code 75-02-04.1-10, effective July 1, 2023). This calculator looks up the official table using ~75% of gross income to estimate net income. Actual net income (after taxes, mandatory deductions) may differ. For net income over $25,000/month, cap amounts apply. Use the official ND HHS guidelines calculator for precise results.
