Nevada child support is a percentage of the paying parent's obligor's gross monthly income (GMI): 16% for one child, 22% for two, rising to 30% for 5 or more (Nev. Admin. Code (NAC) § 425.140). Enter the paying parent's income above for the guideline figure.
How Nevada Calculates Child Support
Nevada calculates support as a tiered percentage of the OBLIGOR's (paying parent's) gross monthly income (GMI) under NAC 425.140, effective February 1, 2020, which replaced the old flat-percentage system in NRS 125B.070. GMI is split into three brackets — a top rate on the first $6,000, a reduced rate on the portion from $6,000 to $10,000, and a further-reduced rate on everything above $10,000 — with bracket rates rising by number of children (16%/8%/4% for one child up to 30%/15%/7.5% for five children, plus scaled add-ons for six or more). Unlike income-shares states, only the paying parent's income is used; for joint physical custody NAC 425.115 computes each parent's obligation separately and the higher one pays the other the net difference. Low-income obligors get a reduced, poverty-guideline-based rate under NAC 425.145, republished every year by the Administrative Office of the Courts.

Nevada Guideline Percentages
| Children | Share of obligor's gross monthly income (GMI) |
|---|---|
| 1 | 16% |
| 2 | 22% |
| 3 | 26% |
| 4 | 28% |
| 5 | 30% |
Worked Example
Obligor GMI = $7,000/month, 2 children. Two-child brackets under NAC 425.140: 22% of the first $6,000 = $1,320, plus 11% of the next $1,000 (the $6,000–$7,000 portion) = $110. Base obligation = $1,430/month. If GMI were $12,000/month instead: 22% of $6,000 = $1,320, 11% of $4,000 ($6,000–$10,000) = $440, 6% of $2,000 (above $10,000) = $120 — total $1,880/month, since there is no upper income cap on the schedule.
When Courts Deviate From the Guideline
- Any special educational needs of the child
- The legal responsibility of either party for the support of others
- The cost of transportation of the child to and from visitation
- The relative income of both households (adjustment may not exceed the other party's own obligation)
- Any other necessary expenses for the benefit of the child
- The obligor's ability to pay
Frequently Asked Questions
Is there a cap on how much child support can be ordered in Nevada?
No. Nevada eliminated its old 'Presumptive Maximum Amount' income cap when NAC 425 took effect February 1, 2020. Under NAC 425.140 the marginal percentage keeps applying to all gross monthly income above $10,000 — 4% for one child, 6% for two or three, 7% for four, plus 0.5% per child beyond four — so there is no dollar ceiling on the calculated obligation.
What counts as 'gross monthly income' for Nevada child support?
GMI under NAC 425 includes wages, salary, commissions, bonuses, self-employment income (after ordinary and necessary business expenses), Social Security, pensions, workers' compensation, unemployment and disability benefits, military allowances, and undistributed business profits. It excludes child support received for other children and means-tested public assistance such as SNAP, TANF, and SSI.
How does joint or shared physical custody change the calculation?
Under NAC 425.115, when parents share joint physical custody the court calculates what each parent would owe the other as if that parent were the sole obligor, then the parent with the higher calculated obligation pays the other parent only the difference between the two amounts.
How long does child support last in Nevada — does it cover college?
Support runs until the child turns 18, or turns 19 if still enrolled in high school, per the definition of 'minor child' in NRS 125B.200. Nevada's guidelines do not statutorily extend support for college; any post-majority college support requires a separate agreement between the parents.
