Understanding North Dakota's Child Support Formula
North Dakota uses the Income Shares model, which is the most widely adopted child support framework in the United States — used by approximately 40 states. The central principle is that a child should receive the same proportion of combined parental income they would have benefited from if both parents had remained together in a single household. Rather than placing the entire burden on one parent, both parents contribute to a baseline obligation determined by their combined income.
In North Dakota, each parent's gross income is converted to net income using a 76% net factor. The two net incomes are added together. A state-published schedule — updated periodically by the legislature, sets the Basic Child Support Obligation for families at each combined income level. Each parent is then responsible for their proportional share of that baseline, adjusted upward for any health insurance premiums or work-related childcare costs they pay. If the paying parent exercises significant parenting time, a parenting time credit may further reduce the obligation.
For example, if Parent A earns 65% of the combined net household income, Parent A pays 65% of the basic obligation, not all of it, and not an arbitrary flat sum. This proportionality is what makes the Income Shares model more equitable for cases where both parents earn meaningful incomes.
Sample North Dakota Child Support Calculation
Scenario: Parent A (paying parent) earns $5,500/month gross. Parent B earns $3,000/month gross. 1 child. Parent A has 20% parenting time.
The final North Dakota order will also factor in any health insurance premiums and work-related childcare costs. Parenting time above 20% typically generates a parenting time credit that can reduce the amount further.
North Dakota Child Support, Frequently Asked Questions
Does North Dakota use Income Shares or the Percentage model?
North Dakota uses the Income Shares model. Both parents' incomes are considered, combined into a total net income figure, and a state schedule determines the baseline child support amount. Each parent then pays their proportional share of that baseline. This means a higher-earning parent in North Dakota will pay a larger fraction of the obligation than a lower-earning one.
What is the average child support payment in North Dakota?
Child support awards in North Dakota typically range from $350–$800/month based on current data. The actual amount varies significantly depending on both parents' incomes, the number of children, custody arrangements, and whether costs like health insurance or childcare are included in the order. Higher income households and multiple children will produce awards above this range.
Can a North Dakota judge order a different amount than the calculator shows?
Yes. The North Dakota guidelines produce a presumptive amount — the starting point, but a judge can deviate from it when following the guidelines would be unjust or inappropriate in a specific case. Common reasons for deviation include extraordinary medical or educational expenses, one parent directly paying significant healthcare premiums, a parent's substantial assets or non-wage income, the needs of children from other relationships, or significant travel costs related to custody exchanges.
How do you modify a child support order in North Dakota?
Either parent can petition the North Dakota court to modify an existing child support order when there has been a substantial change in circumstances. This typically means a significant change in either parent's income (usually 15–20% or more), a change in custody or parenting time, the child developing extraordinary medical or educational needs, or a change in the cost of health insurance. Most states, including North Dakota, also allow automatic review every three years if either party requests it, even without proving a substantial change.
When does child support end in North Dakota?
In North Dakota, child support terminates at: Age 18 (no extension for high school; one of few states ending strictly at 18). The governing law is N.D.C.C. § 14-09-09.7, administered by the ND DHS Child Support. If you have an existing order and believe your child is approaching the termination age, contact ND DHS Child Support or your family law attorney to confirm the specific end date and ensure a formal termination order is entered.
