Important: This calculator estimates the standard base obligation only. It does not apply the annual low-income schedule, determine disputed income, include childcare or medical support, or predict a judicial deviation. The court determines the final amount.
Calculate Estimated Child Support
1. Select the physical custody arrangement
2. Enter monthly gross income and number of children
Example: $60,000 annual income = $5,000 gross monthly income.
Include income before taxes and deductions.
Estimated Child Support Result
Parent 1 base obligation
$0.00
Parent 2 base obligation
$0.00
Estimated monthly payment
$0.00
Not included in this result: the annual low-income schedule under NAC 425.145, childcare, medical support, disputed or imputed income, split custody, Social Security dependent benefits, arrears, or a deviation under NAC 425.150.
A Guideline Number Is Only the Starting Point
We can review income, custody, childcare, insurance, deviations, and the financial records that may change the result.
Discuss Your Child Support EstimateHow Nevada Calculates Child Support
Nevada uses a tiered percentage of an obligor's gross monthly income. The calculation changes depending on whether one parent has primary physical custody or the parents have joint physical custody.
- Determine gross monthly income. The court determines income under NAC 425.025 and NAC 425.120. Income can include more than wages.
- Apply the NAC 425.140 tiers. Different percentages apply to the first $6,000, the portion from $6,000 to $10,000, and the portion above $10,000.
- Apply the custody method. In primary custody, the non-primary parent's obligation is calculated. In joint custody, both obligations are calculated and offset.
- Address adjustments and additional expenses. Low-income rules, deviations, childcare, medical support, and other issues can change the final order.
Nevada Child Support Percentage Tiers
| Children | First $6,000 of GMI | $6,000–$10,000 portion | Portion above $10,000 |
|---|---|---|---|
| 1 child | 16% | 8% | 4% |
| 2 children | 22% | 11% | 6% |
| 3 children | 26% | 13% | 6% |
| 4 children | 28% | 14% | 7% |
| Each additional child | +2% | +1% | +0.5% |
Low-income adjustment: NAC 425.145 requires an annually published low-income schedule when the obligor's economic circumstances limit the ability to pay the standard guideline amount. This calculator does not apply that schedule.
Primary Custody vs. Joint Custody
Primary physical custody
When Parent 1 has primary physical custody, Parent 2 is generally treated as the obligor for the base calculation. When Parent 2 has primary physical custody, Parent 1 is generally treated as the obligor.
Joint physical custody
When the parents share joint physical custody, each parent's base obligation is calculated separately. The lower amount is then subtracted from the higher amount. The parent with the higher obligation generally pays the difference.
A parenting schedule can affect whether the case is treated as primary or joint custody. Use our Nevada parenting plan worksheet to organize schedule terms before discussing the legal effect with an attorney.
Worked Example: $60,000 Annual Income
$60,000 per year equals $5,000 in gross monthly income. Because $5,000 falls within the first tier, the standard base obligation is approximately:
- 1 child: $800 per month
- 2 children: $1,100 per month
- 3 children: $1,300 per month
Those figures are before any low-income adjustment, joint-custody offset, deviation, childcare, or medical-support allocation.
Child Support by Annual Income: Primary-Custody Examples
The examples below assume the listed parent is the non-primary parent and the standard formula applies without a low-income adjustment or deviation.
| Annual income | Monthly income | 1 child | 2 children | 3 children |
|---|---|---|---|---|
| $40,000 | $3,333 | $533 | $733 | $867 |
| $50,000 | $4,167 | $667 | $917 | $1,083 |
| $60,000 | $5,000 | $800 | $1,100 | $1,300 |
| $75,000 | $6,250 | $980 | $1,348 | $1,593 |
| $100,000 | $8,333 | $1,147 | $1,577 | $1,863 |
| $120,000 | $10,000 | $1,280 | $1,760 | $2,080 |
| $150,000 | $12,500 | $1,380 | $1,910 | $2,230 |
What the Calculator Does Not Decide
Gross income disputes and imputed income
The court may review tax returns, pay records, business income, benefits, investment income, and earning capacity. If a parent is unemployed or underemployed without good cause, income may be imputed after the court considers the circumstances listed in NAC 425.125.
Childcare and medical support
The court must consider reasonable childcare costs and must address medical support. Those obligations are separate from the base amount shown by this calculator.
Deviations
Under NAC 425.150, a court may adjust the guideline amount based on the child's needs and the parties' economic circumstances. Relevant issues can include special educational needs, responsibility for supporting others, transportation costs, relative household income, other necessary expenses for the child, and ability to pay.
Modification, Termination, and Enforcement
Modification
A child support order may be modified when there is a legally sufficient change in circumstances or another authorized basis for review. The current guidelines generally apply when the order is reviewed.
Termination
Support generally ends at age 18, or at high-school graduation or age 19, whichever occurs first, when the child remains enrolled in high school. Orders covering multiple children may require a motion or stipulation rather than an automatic reduction.
Enforcement
Unpaid support can result in income withholding, judgments for arrears, license consequences, interception remedies, contempt proceedings, and other enforcement measures. A calculator result is not a substitute for an arrears accounting or review of the actual order.
Frequently Asked Questions About Nevada Child Support
What is the biggest factor in calculating child support in Nevada?
The starting point is gross monthly income. The court determines the applicable base obligation under NAC 425.140 and then applies the custody method. In primary physical custody, the non-primary parent's obligation is calculated. In joint physical custody, both parents' obligations are calculated and offset.
How does joint physical custody affect child support in Nevada?
When the parents have joint physical custody, the base child support obligation is calculated for each parent. The lower obligation is subtracted from the higher obligation, and the parent with the higher obligation generally pays the difference, subject to low-income rules, deviations, and additional expenses.
Does Nevada still have a maximum child support cap?
Nevada no longer uses the former presumptive maximum table. The current guideline applies progressively lower percentages to higher portions of gross monthly income. A court may still adjust the guideline amount when the statutory and regulatory requirements for a deviation are met.
Does Nevada have a low-income adjustment for child support?
Yes. NAC 425.145 requires use of an annually published low-income schedule when the obligor's economic circumstances limit the ability to pay the standard guideline amount. This calculator estimates the standard NAC 425.140 formula and does not apply the annual low-income schedule.
What counts as gross monthly income for Nevada child support?
Gross income can include wages, salary, substantial and consistent overtime, bonuses, commissions, investment income, certain retirement and disability benefits, unemployment benefits, military allowances, alimony received, and other income identified in NAC 425.025. Child support received and certain means-tested public benefits are excluded.
Are health insurance and childcare included in this calculator?
No. The calculator estimates base child support. Nevada courts must also address medical support and consider reasonable childcare costs. Those amounts may be allocated separately and can change the total monthly financial responsibility.
Can a Nevada court order a different amount than the calculator shows?
Yes. A court may deviate from the guideline amount based on the specific needs of the child and the economic circumstances of the parties. The court must make findings explaining the deviation and identify the guideline amount that would otherwise apply.
When does child support end in Nevada?
For one child, support generally ends when the child turns 18, or when the child graduates from high school or turns 19, whichever occurs first, if the child is still enrolled in high school. Different rules may apply to children who cannot support themselves because of a qualifying disability and to orders covering multiple children.
Can child support be modified in Nevada?
Yes. A later modification generally requires a change in circumstances or another legally authorized basis. The court applies the child support guidelines in effect at the time of the review or modification.
Is child support taxable or deductible?
For federal income tax purposes, child support is generally not taxable income to the receiving parent and is not deductible by the paying parent. Tax treatment can depend on the nature of a payment, so individual tax questions should be reviewed with a qualified tax professional.
