Child support · Nevada
Nevada child support calculator
Nevada’s 2020 guidelines set child support as a bracketed percentage of the paying parent’s gross monthly income: for one child, 16% of the first $6,000, 8% of the next $4,000, and 4% above $10,000 — with higher percentages for more children. This calculator applies NAC 425.140 and shows every step.
Calculate guideline support
Enter both parents’ annual gross income. Add annual child care and the children’s health-insurance cost if any. Parenting-time overnights are optional.

More children, higher percentages
The bracket percentages rise with the number of children. On the first $6,000 of monthly income the rate is 16% for one child, 22% for two, 26% for three, 28% for four, and 30% for five — with correspondingly higher rates on the middle and top brackets (for example, 22/11/6% for two children and 30/15/8% for five). This calculator applies the exact bracket set for the number of children you choose.
Nev. Admin. Code § 425.140(1)–(5).
Adjustments and low income
The bracket amount is the base obligation. Nevada then allows the court to adjust it (up or down) for a defined list of factors — the cost of health insurance and child care, a child’s special needs, the relative income of both households, and the amount of time the child spends with each parent (NAC 425.150). A separate low-income adjustment applies when the obligor’s income is near the federal poverty level (NAC 425.145). Those adjustments are case-specific, so this calculator shows the base schedule amount.
Nev. Admin. Code §§ 425.145, 425.150.
Shared physical custody
When each parent has the child at least 40% of the time, Nevada treats it as joint physical custody: the court computes each parent’s obligation under the schedule and offsets them, so the parent with the larger amount pays the difference. Because that needs both parents’ incomes and the exact time split, this calculator computes a single-parent obligation; use the offset for a true joint-custody case.

A number with the method attached is the honest form of the same figure.
What this calculator does not do
It computes the base schedule obligation from the paying parent’s gross monthly income. It does not apply the low-income adjustment, add or offset specific costs (health insurance, child care, special needs), or run the joint-custody offset. For a figure you can file, use the Nevada worksheet or consult an attorney.
Common questions
How is child support calculated in Nevada?
Since 2020, a bracketed percentage of the paying parent’s gross monthly income (NAC 425.140): for one child, 16% of the first $6,000, 8% of $6,000–$10,000, and 4% above $10,000, rising with the number of children.
What are the Nevada child support percentages?
On the first $6,000/mo: 16% (1 child), 22% (2), 26% (3), 28% (4), 30% (5), with lower rates on the higher brackets.
Did Nevada change its formula?
Yes — effective February 1, 2020, the bracketed NAC 425.140 schedule replaced the old flat 18% cap.
What about shared custody?
When each parent has the child at least 40% of the time, the court offsets each parent’s obligation and the higher-earning parent pays the difference.
Is child support taxable in Nevada?
No — federally it’s not taxable to the recipient or deductible by the payer, the same in Nevada as everywhere.
