Nevada calculates child support using a tiered percentage-of-income formula applied to the obligor parent's gross monthly income (GMI). For one child, a parent pays 16% of the first $6,000 in GMI, 8% on income between $6,001 and $10,000, and 4% on income above $10,000 under NAC 425. A child support calculator Nevada families can rely on uses these exact statutory brackets to produce an accurate estimate, though a court retains discretion to deviate based on 12 enumerated factors in NRS 125B.080. The state eliminated its former presumptive maximum cap when these graduated brackets took effect on February 1, 2020, meaning high-income parents may owe substantially more than under the old formula.

How Nevada's Child Support Formula Works
Nevada uses a tiered percentage-of-income model that applies three separate rates to different income brackets of the obligor parent's gross monthly income. For one child, the obligor pays 16% on the first $6,000 of GMI, 8% on income from $6,001 to $10,000, and 4% on all income exceeding $10,000. This graduated structure replaced the flat-percentage system on February 1, 2020, when regulations under NAC 425 took effect. The child support calculator Nevada courts recognize applies these exact brackets.
The tiered model works like a progressive tax bracket. Each dollar of income is taxed at the rate for its bracket, not at a single flat rate. For example, a parent earning $8,000 per month with one child would owe $1,120: $960 (16% of $6,000) plus $160 (8% of $2,000). This design ensures that lower-income parents pay a smaller effective percentage while higher-income parents contribute proportionally more.
The percentages increase with additional children. For two children, the rates are 22%, 11%, and 6% across the same brackets. For three children, the rates climb to 26%, 13%, and 6%. Each additional child beyond three adds 2% to the base-tier rate. These graduated percentages are codified in NRS 125B.070 and implemented through the Nevada Administrative Code.
Nevada Child Support Percentage Table by Number of Children
The following table shows the exact percentages applied at each income tier under Nevada's child support guidelines. Every child support calculator Nevada parents use should reflect these rates.
| Number of Children | First $6,000 GMI | $6,001 to $10,000 GMI | Above $10,000 GMI |
|---|---|---|---|
| 1 child | 16% | 8% | 4% |
| 2 children | 22% | 11% | 6% |
| 3 children | 26% | 13% | 6% |
| 4 children | 28% | 14% | 6% |
| Each additional child | +2% | +1% | +0% |
These rates apply to the obligor's gross monthly income before any deductions for taxes, retirement, or personal expenses. The graduated structure means a parent earning $15,000 per month with two children pays a total of $2,060: $1,320 (22% of $6,000) plus $440 (11% of $4,000) plus $300 (6% of $5,000).
What Counts as Gross Monthly Income in Nevada
Gross monthly income under Nevada law means the total amount of income received each month from any source before deductions for personal income taxes, retirement contributions, or personal expenses. NRS 125B.070 defines GMI broadly to include wages, salaries, commissions, bonuses, dividends, pensions, rental income, Social Security benefits, workers' compensation, unemployment insurance, and trust income. Self-employed parents use gross income after deducting legitimate business expenses but before personal deductions.
Nevada courts include the following income sources when calculating child support:
- Wages, salaries, tips, and overtime pay
- Bonuses and commissions
- Self-employment income (net of business expenses)
- Investment income including dividends, interest, and capital gains
- Rental and royalty income
- Pension and retirement distributions
- Social Security benefits (including disability)
- Workers' compensation benefits
- Unemployment insurance benefits
- Spousal support received from a prior marriage
- Trust and annuity income
- Military pay and allowances
Nevada courts do not deduct income taxes, Social Security contributions, health insurance premiums, or 401(k) contributions from gross monthly income before applying the child support percentages. This pre-tax, pre-deduction calculation is a common source of confusion among parents who expect child support to be based on take-home pay. The only deduction permitted for self-employed parents is for legitimate, ordinary, and necessary business expenses documented on tax returns.
Step-by-Step Guide to Using the Nevada Child Support Calculator
Nevada's Administrative Office of the Courts provides an official child support guidelines calculator that applies the statutory formula automatically. The Divorce.law child support calculator for Nevada also applies these exact brackets. Follow these steps to calculate an estimated child support obligation.
Step 1: Determine the obligor parent's gross monthly income from all sources listed in NRS 125B.070. Add up wages, investment income, rental income, benefits, and all other income before taxes or deductions.
Step 2: Identify the number of children covered by the support order. Each child increases the percentage applied at every income tier.
Step 3: Apply the tiered percentages to the obligor's GMI. Calculate 16% (for one child) of the first $6,000, then 8% of income between $6,001 and $10,000, then 4% of income above $10,000.
Step 4: Add the three amounts together to arrive at the presumptive child support obligation.
Step 5: Review the 12 deviation factors in NRS 125B.080 to determine whether the court may adjust the amount upward or downward.
Step 6: Account for any credits, such as the amount the obligor parent pays for the child's health insurance premiums, which may reduce the net obligation.
Sample Child Support Calculations for Common Income Levels
The following examples demonstrate how the tiered formula produces different results at various income levels. These calculations assume one child with the non-custodial parent as the obligor.
For a parent earning $4,000 per month (GMI) with one child: 16% of $4,000 equals $640 per month in child support. The entire income falls within the first bracket.
For a parent earning $8,000 per month (GMI) with one child: 16% of $6,000 ($960) plus 8% of $2,000 ($160) equals $1,120 per month. The effective rate is 14%.
For a parent earning $12,000 per month (GMI) with one child: 16% of $6,000 ($960) plus 8% of $4,000 ($320) plus 4% of $2,000 ($80) equals $1,360 per month. The effective rate drops to 11.3%.
For a parent earning $20,000 per month (GMI) with two children: 22% of $6,000 ($1,320) plus 11% of $4,000 ($440) plus 6% of $10,000 ($600) equals $2,360 per month. The effective rate is 11.8%.
| Gross Monthly Income | 1 Child | 2 Children | 3 Children |
|---|---|---|---|
| $3,000 | $480 | $660 | $780 |
| $5,000 | $800 | $1,100 | $1,300 |
| $6,000 | $960 | $1,320 | $1,560 |
| $8,000 | $1,120 | $1,540 | $1,820 |
| $10,000 | $1,280 | $1,760 | $2,080 |
| $15,000 | $1,480 | $2,060 | $2,380 |
| $20,000 | $1,680 | $2,360 | $2,680 |
When Courts Deviate from the Calculator Amount
Nevada courts may deviate from the calculated child support amount when applying the formula would be unjust or inappropriate under the circumstances. NRS 125B.080 lists 12 specific factors a court must consider when deciding whether deviation is warranted. The court must make written findings explaining any deviation from the guideline amount.
The 12 deviation factors under NRS 125B.080 include:
- The cost of health insurance for the child
- The cost of child care
- Any special educational needs of the child
- The age of the child
- The legal responsibility of the parents for the support of other children or persons
- The value of services contributed by either parent
- Any public assistance paid to support the child
- Any expenses reasonably related to the mother's pregnancy and confinement
- The cost of transportation for visitation
- The amount of time the child spends with each parent
- Any other necessary expenses for the benefit of the child
- The obligor's ability to meet basic personal needs while paying support
Courts frequently grant downward deviations when the obligor parent exercises substantial parenting time (40% or more of overnights), pays for the child's health insurance, or supports other biological or adopted children. Upward deviations are common when the child has special medical, educational, or therapeutic needs that exceed typical expenses.
How Shared Custody Affects Child Support in Nevada
Nevada does not use a strict 50/50 offset formula for shared custody. Even when parents share physical custody equally, one parent typically earns more and will owe some child support to the other parent. The court calculates each parent's obligation under the tiered formula, then offsets the smaller amount against the larger. The difference becomes the net child support payment from the higher-earning parent to the lower-earning parent.
For example, if Parent A earns $10,000 per month (GMI) and Parent B earns $5,000 per month (GMI) with one child under joint custody, the court calculates each parent's obligation: Parent A owes $1,280 and Parent B owes $800. The offset yields a net payment of $480 per month from Parent A to Parent B. Courts may further adjust this amount based on the actual percentage of overnights each parent exercises under NRS 125B.080.
The offset method applies only when both parents have court-ordered physical custody. In primary custody arrangements where one parent has the child more than 60% of overnights, only the non-custodial parent's income is used in the child support calculator Nevada courts apply.
How to Modify a Nevada Child Support Order
A Nevada child support order may be modified at any time based on changed circumstances under NRS 125B.145. A change of 20% or more in the obligor's gross monthly income automatically constitutes changed circumstances sufficient to justify a modification review. Either parent may also request a routine review every 3 years regardless of whether income has changed.
To file for modification, a parent submits a Motion to Modify Child Support to the district court that issued the original order. The filing fee for a motion in Nevada ranges from $50 to $75 depending on the county. The motion must include documentation of the changed circumstances, such as recent pay stubs, tax returns, or proof of job loss.
Common grounds for modification include:
- A 20% or greater increase or decrease in either parent's gross monthly income
- A change in custody or parenting time arrangement
- A change in the child's medical, educational, or special needs
- The child reaching age 18 or graduating from high school (whichever occurs later)
- A parent becoming disabled or incarcerated
- A substantial change in the cost of health insurance for the child
Nevada courts will not modify a child support order retroactively. The modified amount takes effect from the date the motion is filed, not from the date circumstances changed. Parents who experience income changes should file promptly to avoid accumulating arrears at the old support amount.
Child Support Enforcement in Nevada
The Nevada Division of Welfare and Supportive Services (DWSS) Child Support Enforcement Program collects unpaid child support through wage garnishment, tax refund intercepts, license suspensions, passport denial, and contempt of court proceedings. Nevada collected approximately $290 million in child support payments in federal fiscal year 2023 according to the federal Office of Child Support Enforcement.
Enforcement tools available to Nevada child support agencies include:
- Income withholding orders served directly on employers
- Interception of federal and state tax refunds
- Suspension of driver's licenses, professional licenses, and recreational licenses
- Denial of U.S. passport for arrears exceeding $2,500
- Bank account levies and asset seizure
- Reporting to credit bureaus
- Contempt of court proceedings with potential jail time up to 6 months
- Referral for criminal prosecution for willful nonpayment exceeding $10,000
A parent who falls behind on child support cannot discharge the debt in bankruptcy. Child support arrears survive bankruptcy under both Chapter 7 and Chapter 13 filings. Interest accrues on unpaid child support at a rate set by the court, which further increases the total obligation over time.
How Long Does Child Support Last in Nevada
Child support in Nevada continues until the child turns 18 years old, or until age 19 if the child is still enrolled in high school under NRS 125B.110. The obligation terminates automatically upon the child's emancipation, marriage, or entry into active military duty. Nevada does not require parents to pay child support for college-age children, unlike some states that extend support through age 21 or 23 for students enrolled in higher education.
The duration of child support cannot be shortened by agreement between the parents. Even if both parents agree in a divorce settlement that child support will end at age 16, a court will not enforce that provision because child support is a right belonging to the child, not the parents. However, parents may agree to extend support beyond age 18 for a child with disabilities or special needs, and courts will enforce those agreements.
Filing for Child Support in Nevada
A parent can establish a child support order in Nevada through a divorce proceeding, a separate child support action, or through the DWSS Child Support Enforcement Program. The residency requirement under NRS 125.020 requires at least one spouse to have lived in Nevada for 6 weeks before filing for divorce. Filing fees range from $217 in rural counties like Nye County to $364 in Clark County (Las Vegas) as of March 2026. Verify current fees with your local district court clerk.
To file for child support outside of a divorce, a parent files a Complaint for Support with the district court. The court will order both parents to complete financial disclosure forms documenting all sources of income. Nevada courts may impute income to a voluntarily unemployed or underemployed parent at the level the parent could reasonably earn based on education, work history, and local job market conditions under NRS 125B.080(8).
The DWSS Child Support Enforcement Program provides free services to establish paternity, locate absent parents, establish child support orders, and enforce existing orders. Parents can apply online at the Nevada DWSS website or by calling the Child Support Hotline.
Frequently Asked Questions About Nevada Child Support
How is child support calculated in Nevada in 2026?
Nevada calculates child support using a tiered percentage of the obligor parent's gross monthly income. For one child, the rate is 16% of the first $6,000 in GMI, 8% on income between $6,001 and $10,000, and 4% on income above $10,000 under NRS 125B.070. A parent earning $8,000 per month with one child would owe $1,120 monthly.
Does Nevada have an official child support calculator?
Yes. The Nevada Administrative Office of the Courts provides a free child support guidelines calculator that applies the statutory tiered percentage formula. Divorce.law also offers a child support calculator for Nevada that uses the same brackets. Both calculators produce a presumptive amount the court may adjust based on deviation factors.
What income is used to calculate child support in Nevada?
Nevada uses gross monthly income before taxes, retirement contributions, and personal deductions. GMI includes wages, salaries, bonuses, commissions, investment income, rental income, Social Security benefits, workers' compensation, unemployment benefits, pension distributions, and trust income under NRS 125B.070. Self-employed parents deduct legitimate business expenses but not personal expenses.
Can a Nevada judge order more or less than the calculator amount?
Yes. Nevada courts may deviate from the guideline amount based on 12 factors listed in NRS 125B.080, including health insurance costs, child care expenses, special needs of the child, parenting time arrangements, and the obligor's ability to meet basic personal needs. The court must make written findings explaining any deviation from the calculated amount.
How do I modify child support in Nevada?
A parent files a Motion to Modify Child Support with the district court under NRS 125B.145. A 20% change in gross monthly income automatically qualifies as changed circumstances. Either parent may also request a routine review every 3 years. The modified amount takes effect from the filing date, not retroactively, so parents should file promptly when circumstances change.
How does joint custody affect child support in Nevada?
Nevada uses an offset method for joint physical custody. The court calculates each parent's child support obligation separately using the tiered formula, then subtracts the smaller amount from the larger. The higher-earning parent pays the difference. For example, with one child, if Parent A owes $1,280 and Parent B owes $800, Parent A pays $480 per month net to Parent B.
What happens if a parent does not pay child support in Nevada?
Nevada enforces child support through wage garnishment, tax refund intercepts, license suspensions (driver's, professional, and recreational), passport denial for arrears over $2,500, bank levies, credit reporting, and contempt proceedings carrying up to 6 months in jail. Arrears exceeding $10,000 may result in criminal prosecution. Child support debt cannot be discharged in bankruptcy.
At what age does child support end in Nevada?
Child support in Nevada terminates when the child turns 18 years old under NRS 125B.110. If the child is still enrolled in high school at age 18, support continues until age 19 or graduation, whichever comes first. The obligation also ends upon the child's emancipation, marriage, or entry into active military duty. Nevada does not require support for college-age children.
What is the minimum child support payment in Nevada?
Nevada eliminated the statutory minimum payment of $100 per month when the tiered formula took effect in February 2020. The current minimum is determined by applying the percentage formula to the obligor's actual gross monthly income. If a parent earns $0, the court may impute income based on earning capacity under NRS 125B.080(8). Courts rarely set support at $0 for an able-bodied parent.
Can child support be waived in Nevada?
No. Child support is a legal right belonging to the child, not the parents, and cannot be waived by parental agreement under Nevada law. Parents cannot contract away a child's right to financial support. However, parents may agree on an amount different from the guideline calculation, and the court will approve the agreement if it adequately meets the child's needs and is not unconscionable.
