Calculate Estimated Child Support
1. Select the physical custody arrangement
2. Enter monthly gross income and number of children
Estimated Child Support Result
Most contested Nevada child support cases turn on those items rather than the base percentage. Continue to the additional expenses worksheet below.
Additional Expenses and Possible Deviations Worksheet
The guideline number above covers base support. It does not cover health insurance, childcare, tuition, activities, or the other costs parents actually argue about. Nevada courts handle those separately, and they are treated very differently from one another.
For each expense, enter the monthly cost, identify who pays it now, and select the percentage you propose each parent should ultimately bear. The worksheet will show the resulting increase or decrease to the guideline transfer payment. It is a proposed adjustment only; the court determines whether any deviation or allocation is appropriate.
Read this before you enter anything. Nothing in this worksheet is a guaranteed add-on. Nevada has no formula that adds these expenses to base support. Some must be addressed by the court, some are discretionary under NAC 425.150, and some are routinely rejected unless both parents agree or there is an established history. A judge can decline every item below.
Enter the cost, current payer, and proposed Parent 1 share. Parent 2 receives the remainder.
Example: If Parent 1 pays a $400 expense now and you propose a 50/50 allocation, Parent 2 would owe Parent 1 $200. If Parent 1 is the support payor, the proposed transfer payment decreases by $200; if Parent 1 receives support, it increases by $200.
Costs the court is required to address
Strongest positionNevada child support orders must address medical support, and the court must consider reasonable childcare costs. These are the items least likely to be ignored, though the court still decides how they are allocated between the parents.
Discretionary deviation factors listed in NAC 425.150
Argued case by caseNAC 425.150 lets a court adjust the guideline amount for specific reasons, including any special educational needs of the child, the cost of transportation for visitation, and other necessary expenses for the child’s benefit. Listed does not mean automatic. The court must make findings, and documentation carries the argument.
Costs frequently contested and often not added
Weakest positionThese are not separately listed in NAC 425.150. To be added, they generally need to fit an existing deviation factor, be supported by an agreement between the parents, or rest on an established history the child already relies on. Expect these to be the hardest items to win.
Your Proposed Expense Adjustment
This is a proposal, not a prediction. The calculation accounts for who pays each expense now and your proposed allocation. A Nevada court may allocate an item differently or decline the proposed adjustment entirely.
Bring these to your consultation
Based on what you entered. Documentation is what moves these items, not the dollar figure alone.
Additional Expenses Are Where These Cases Are Actually Won or Lost
Two parents with identical incomes can end up with very different orders depending on how insurance, childcare, tuition, and activities were documented and argued.
Review Your Expenses With Our TeamParents usually arrive focused on the percentage. The percentage is the part nobody argues about, because it is set by regulation and the arithmetic is fixed. What actually moves the monthly number is gross income and everything in the worksheet above.
Two things consistently make a difference: documenting an expense before it is contested rather than after, and being able to show what the child was already receiving. An expense that has been paid consistently for two years is a different argument than one that appears for the first time in a motion.
How 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% |
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.
Why a deviation is never automatic
A court that deviates from the guideline amount must identify the guideline figure that would otherwise apply and make findings explaining the adjustment. That requirement cuts both ways: it protects against arbitrary changes, and it means an expense alone is not enough. The record has to support the deviation.
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. See our Nevada post-divorce modifications page for how that process works.
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. See our guide to Nevada child support enforcement.
Watch: The 30/30 Rule for Children's Expenses
The calculated support figure is not everything either parent pays. Medical costs, co-pays, activity fees and other shared expenses sit outside it, and Nevada gives you a window to ask for reimbursement and a window to pay one. Miss the first and you may lose the money.

Frequently Asked Questions About Nevada Child Support
Does child support cover extracurricular activities in Nevada?❯
Activity costs are not separately listed as a deviation factor in NAC 425.150, and they are frequently treated as already covered by base support. Adding them usually depends on an agreement between the parents, an established history the child relies on, or an argument that the cost fits one of the listed deviation factors. Substantial documented costs for a competitive program are a stronger argument than ordinary activity fees.
Can I be ordered to pay for private school on top of child support in Nevada?❯
It is possible but not automatic. Private school tuition is not separately listed in NAC 425.150. The argument is strongest where the child was already enrolled with both parents' agreement, or where the placement addresses a documented educational need. It is weakest where one parent makes a new unilateral enrollment decision and asks the other to fund it. The court considers the child's needs and both parties' economic circumstances.
How is health insurance handled in a Nevada child support order?❯
Nevada child support orders must address medical support, so this is generally the strongest of the additional expense categories. The relevant figure is usually the portion of the premium attributable to the child rather than the entire family plan cost, which is why a per-dependent breakdown from the insurance carrier matters. Unreimbursed out-of-pocket costs are commonly allocated between the parents by percentage.
Is childcare added to child support in Nevada?❯
The court must consider reasonable childcare costs, but how they are allocated depends on the case. Care that is necessary so a parent can work or attend school is treated differently from care chosen for convenience. Provider statements and proof of payment carry more weight than an estimate.
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. In contested cases, disputes over income and additional expenses usually matter more than the percentage itself.
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.
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.
