A Nevada parent with $5,000 of gross monthly income owes $800 a month for one child, because NAC 425.140 takes 16% of the first $6,000 of income. Beyond that the rate falls: 8% on the slice from $6,000 to $10,000, 4% above $10,000, with higher rates for more children (22%, 11% and 6% for two). There is no income cap and no deduction for taxes. When both parents have joint physical custody, each one's amount is computed and the larger is reduced by the smaller, with no multiplier: at $8,000 and $4,000 with two children the order drops from $1,540 to $660. Parents earning up to $1,995 a month can be placed on the low-income schedule, $206 for one child at $1,500.
Guideline child support in Nevada, per month
$800
$9,600 a year
| Obligor’s gross monthly income | $5,000 |
| Base obligation, 1 child (NAC 425.140 tiers) | $800 |
Estimate under the Nevada guideline as published, from the incomes you enter. Deviations, imputed income, other children and the judge's findings can change the order. How this is calculated.
Income sliced like a tax bracket
Nevada rewrote its guideline in 2020, when regulations of the Division of Welfare and Supportive Services replaced the old statutory percentages of NRS 125B.070. The new rule reads like an income tax schedule turned upside down: each slice of gross monthly income carries its own rate, and the rate shrinks as income grows. Two children at $8,000 cost $1,540, not the $1,760 a flat 22% would give. Three children at $12,000 come to $2,200.
Families with more than four children are not left at the four-child rate. Each additional child adds 2% in the first slice, 1% in the second and 0.5% in the third, so five children at $15,000 lead to $2,775 a month.
Joint custody means two obligors
NAC 425.037 makes each parent an obligor when custody is joint. The court figures both amounts with the same tiers and nets them; the parent with the higher figure pays the difference. The regulation sets no night count. The custody statute, NRS 125C.003, presumes joint physical custody is not in the child's interest when a parent cannot care for the child at least 146 days a year, and our calculator uses that line. Below it, a payer at $8,000 owes $1,540 for two children; from 146 days, with a co-parent at $4,000, the offset leaves $660.
The offset uses each parent's own guideline amount, including the low-income schedule. In the official calculator, a parent at $6,000 sharing one child with a parent at $1,500 pays $754, because the lower earner's figure comes from the schedule rather than the tiers.
The yearly low-income schedule
The Administrative Office of the Courts publishes a new schedule by March 31 each year, keyed to the federal poverty guidelines. In the 2026 version used by the state's calculator, the first row covers gross income up to $998 and the last reaches $1,995. A parent at $1,500 with one child pays $206 instead of $240; at $600, $105. A judge may still go lower when income is below the schedule, balancing the parent's self-support.
Child care is divided equitably by the court and every order must provide medical support, with a premium treated as reasonable up to a share of gross income set in NAC 425.135. Those sit outside the base figure the calculator returns. Nevada's neighbor California works from both parents' net incomes instead, and Idaho uses an income-shares table.

How the amount is set. Base obligation = sum over income tiers: 1 child 16% / 8% / 4%; 2 children 22% / 11% / 6%; 3 children 26% / 13% / 6%; 4 children 28% / 14% / 7%; each additional child adds 2% / 1% / 0.5%, for the first $6,000, the portion from $6,000 to $10,000, and the portion above $10,000 of the obligor's monthly gross income (NAC 425.140). There is no income cap. source
Income. Gross income includes salary and wages (with substantial, consistent overtime), interest and investment income, Social Security disability and old-age benefits, periodic pension/retirement/annuity payments, income-replacing workers' compensation or injury awards, unemployment insurance, income continuation benefits, voluntary deferred-compensation and retirement contributions, military allowances and veterans benefits, compensation for lost wages, certain undistributed business income, child care subsidies received as a provider, alimony, and all other income; it excludes child support received, foster or kinship care payments, SNAP, county cash benefits, SSI, other public assistance, and non-income-replacing injury damages (NAC 425.025). No taxes are deducted.
Above the table. Above the schedule the NAC 425.140 tiers apply.
Parenting time. With primary physical custody, the other party is the obligor. With joint physical custody of a child, each party's obligation is determined and the obligations are offset, the higher one paying the difference; with split custody of two or more children, each party's obligation is computed for the children in the other's custody and offset (NAC 425.115(2)-(4)). There is no multiplier. NAC 425 sets no time threshold; NRS 125C.003(1)(a) uses 146 days a year as the floor below which joint physical custody is presumed not in the child's interest.
Child care and health care. The court must consider the reasonable child care costs paid by either or both parties and make an equitable division (NAC 425.130). Every order must provide for medical support (premium for accessible medical, vision or dental coverage that is reasonable in cost, i.e. not more than 5% of the party's monthly gross income) (NAC 425.135). Adjustments are possible for special educational needs, support of others, services contributed, public assistance, visitation transportation, relative household incomes, other necessary expenses and ability to pay, with findings (NAC 425.150).
Low incomes. When the obligor's total economic circumstances limit the ability to pay, the obligation is set with the low-income schedule based on the federal poverty guidelines, published yearly by the Administrative Office of the Courts by March 31 (NAC 425.145). The 2026 schedule applied by the official calculator runs from 'up to $998.00' to 'up to $1,995.00' of monthly gross income, e.g. $105 for one child up to $998.00 and $206 for one child from $1,496.01 to $1,532.00 (full table in cs-schedules/nevada.json).
When support ends. Support for one child ends when the child turns 18 or, if still in high school, at graduation or age 19, whichever comes first (NAC 425.160(1)). source
The state also runs its own official child support calculator; use it, or the court's worksheet, for a filing.
Worth knowing in Nevada
- Nevada's current guidelines took effect February 1, 2020 (LCB File R183-18), replacing the former statutory percentages in NRS 125B.070. source
- The guideline percentages fall as income rises (marginal tiers at $6,000 and $10,000 per month) and there is no income cap. source
- Incarceration or involuntary institutionalization for 180 consecutive days or more is a substantial change in circumstances, and income may not be imputed to an incarcerated obligor (NAC 425.155). source
- A stipulated amount that departs from the guidelines must state each party's gross income, the guideline amount, and certify that the child's basic needs are met (NAC 425.110). source
- The Division of Welfare and Supportive Services (DWSS) runs the IV-D child support program and links the official guidelines calculator. source
