How Nevada calculates child support
Nevada 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: NRS 425.620; NAC 425.140 — 2020 overhaul (NAC 425) replaced flat percentages with tiered marginal percentages of gross monthly income plus low-income obligation tables adjusted annually.
Nevada's guideline percentages of the paying parent's gross income:
| Children | Percentage of income |
|---|---|
| 1 | 16% |
| 2 | 22% |
| 3 | 26% |
| 4 | 28% |
| 5 | 30% |
Frequently asked questions
How is child support calculated in Nevada?
Nevada 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 NRS 425.620; NAC 425.140.
Is this the exact amount a Nevada 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, consult your court’s self-help center or a family law attorney.
Does parenting time affect child support in Nevada?
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; Nevada's courts apply their own specific rules, so treat shared-custody results as rough estimates.
What income counts for child support in Nevada?
Generally all income: wages, self-employment, bonuses, commissions, and often investment income. Nevada's guideline uses gross (pre-tax) income figures. Courts may also impute income to a parent who is voluntarily unemployed or underemployed.
