Nevada Child Support Calculator
Estimate your monthly child support obligation under NAC § 425.140. Enter your numbers below for an instant estimate with a step-by-step breakdown and statute citations.
What You'll Need
Gather these four figures first for an accurate Nevada estimate:
- Each parent's gross monthly income — recent pay stubs and last year's tax return are the best source.
- Number of children covered by the order.
- Parenting time — roughly how many overnights per year the child spends with each parent.
- Monthly health insurance and childcare costs for the children.
Nevada Child Support Calculator
This state uses the Percentage of Income model, which calculates support based solely on the obligor's (paying parent's) net income.

How Nevada Calculates Child Support
Nevada determines child support using the Percentage of Income Model, the standard set out in NAC § 425.140. Under this model, support is based primarily on the paying parent's income: a set percentage (which usually rises with the number of children) is applied to that parent's income to produce the obligation.
The calculator above applies that formula to the income and expense figures you enter and shows each step of the math, so you can see exactly how the estimate is built. Because every order ultimately runs through a judge, the guideline figure is a starting point rather than a guaranteed result — the sections below explain what goes into it and where real orders can differ.
Key Rules Behind the Nevada Formula
- Nevada uses a Percentage of Income model based exclusively on the obligor's (NCP's) gross monthly income under NAC § 425.140, effective February 1, 2020. The custodial parent's income does not affect the primary custody support obligation.
- The schedule applies three income tiers to gross income before taxes: the first $6,000/month, the next $4,000 ($6,001–$10,000), and any income above $10,000/month. A lower percentage applies in each successive tier.
- Rates for 1 child: 16% / 8% / 4%. For 2 children: 22% / 11% / 6%. For 3 children: 26% / 13% / 6%. For 4 children: 28% / 14% / 7%. Each additional child above 4 adds 2% / 1% / 0.5% to each bracket respectively.
- "Gross income" under NAC § 425.025 means all income before federal and state taxes — wages, bonuses, commissions, overtime (if consistent), pensions, VA disability, SSDI, military allowances, workers' comp, and other sources. There is no deduction for income taxes or FICA, unlike some other states.
- There is no income ceiling on the bracket tiers — Bracket 3 rates (4%/6%/6%/7%/7.5%/8%) continue indefinitely above $10,000/month. However, NRS § 125B.070(2)–(3) also establishes per-child per-month dollar caps (CPI-adjusted each July 1 from 2003 base values; approximately $728–$1,165/child/month as of 2024). The NAC 425.140 tiered schedule generally produces amounts within these caps at typical income levels.
- The minimum support award is $100 per child per month per NRS § 125B.080(4), unless the court makes a written finding that the obligor is unable to pay even that amount. Willful underemployment is not grounds to deviate below the minimum.
- Joint physical custody applies when the obligor has 146 or more overnights per year (40% or more of the year). Under NAC § 425.115, each parent's obligation is calculated separately using the same tiered schedule, then the parent with the higher obligation pays the other the difference.
- Prior to February 1, 2020, Nevada used flat percentages from NRS § 125B.070 (18% for 1 child, 25% for 2, 29% for 3, 31% for 4, +2% each additional). Those flat rates are no longer operative for new or modified orders.
What Counts as Income
Child support guidelines are built on each parent's income, so the figure you enter matters more than any other input. Most states start from a broad definition of gross income that includes wages, salary, tips, commissions, bonuses, self-employment earnings, and many forms of government benefits, then subtract specific deductions to reach the income the formula actually uses.
Nevada's rules under NAC § 425.140 spell out which deductions apply and whether the formula runs on gross or net income. The calculator's field labels tell you which figure to enter; when in doubt, use your most recent pay stubs and tax return, and confirm the details in the Nevada child support laws guide.
How to Establish a Child Support Order in Nevada
A child support obligation becomes enforceable only once a court or the state child support agency issues an order. Either parent can request one, and in Nevada, as in every state, the local child support agency that operates under the federal Title IV-D program can open a case, locate the other parent, establish paternity if needed, and ask the court to set support using the guideline formula.
When you apply, expect to provide proof of income for both parents, the child's information, and details about health insurance and childcare costs — the same inputs this calculator uses. Running your numbers here first gives you a realistic idea of the order amount before you file.

Important Legal Disclaimer
This calculator provides an estimate only based on Nevada's child support guidelines. Actual court-ordered amounts may differ based on factors not captured here, including special needs, shared custody arrangements, travel costs, and judicial discretion.
This is not legal advice. Consult a family law attorney for guidance specific to your situation.
How to Modify a Nevada Child Support Order
Child support orders are not permanent. Nevada courts can revisit an order when there has been a substantial change in circumstances — for example, a significant change in either parent's income, a change in custody or parenting time, or a meaningful change in the child's needs. Federal rules also entitle parents in IV-D cases to request a review periodically (often about every three years) even without a major change.
To estimate a new amount, re-run the calculator with the updated figures. If the guideline result is meaningfully different from your current order, that gap is often what supports a modification request — though only a court can actually change the order.
How Child Support Is Enforced in Nevada
Once an order is in place, Nevada has strong tools to collect it. The most common is income withholding: federal law requires most new orders to be paid through automatic wage garnishment, so payments are deducted from the paying parent's paycheck. When payments fall behind, enforcement can escalate to intercepting tax refunds, suspending driver's or professional licenses, placing liens on property, reporting the debt to credit bureaus, and, in serious cases, contempt-of-court proceedings.
Interest and penalties can accrue on unpaid support, so an order that goes unaddressed tends to grow rather than disappear. If your circumstances have changed, seeking a modification through the court is almost always better than simply paying less than the order requires.
Frequently Asked Questions
Is this Nevada child support calculator accurate?
It applies the official Nevada guideline formula from NAC § 425.140 to the numbers you enter, so it gives a close estimate of a typical guideline order. It is not an official court calculation — a judge can order a different amount based on the specific facts of your case.
Can a judge order a different amount than the calculator shows?
Yes. The guideline figure is a presumptive starting point, but Nevada courts can deviate up or down when the standard amount would be unfair — for example, because of extraordinary medical or educational expenses, a child's special needs, or other obligations. The order the judge signs controls.
What income do I enter into the Nevada calculator?
Use the figures described by each field's label — generally your regular income from work and other sources. Nevada's guidelines define exactly which income counts and which deductions apply, so your most recent pay stubs and tax return are the best source for accurate numbers.
Is child support taxable in Nevada?
No. Under federal tax law, child support is not taxable income for the parent who receives it and is not tax-deductible for the parent who pays it. This is different from spousal support and does not change from state to state.
How long does child support last in Nevada?
In most cases child support continues until the child reaches the age of majority or finishes high school, but orders can extend longer — for instance, for a child with a disability. Check the Nevada child support laws guide for the specific rules that apply to your situation.
Disclaimer
This calculator provides estimates only and is not a substitute for legal advice. The actual amount ordered by a Nevada court may differ based on factors including but not limited to: the special needs of the child, travel expenses for visitation, extraordinary educational or medical expenses, the parents' other support obligations, and the court's discretion to deviate from the guidelines. For advice about your specific situation, consult a licensed Nevada family law attorney.
