Nevada Child Support Calculator
Estimate the presumptive Nevada base child support from the paying parent's gross monthly income.
Estimate only — not legal advice. This is an educational estimate of the presumptive base obligation under Nevada's 2020 guidelines (NAC 425). It is not legal advice and omits adjustments the court applies — low-income limits, health-care and childcare costs, shared physical custody and more. Consult a Nevada family-law attorney or the court for an official figure.
Nevada's 2020 guidelines set child support as a tiered percentage of the obligor's gross monthly income. For one child it is 16% of the first $6,000, 8% of income from $6,000 to $10,000, and 4% above $10,000. The percentages rise with more children. This is the base obligation before court adjustments.
⚠️ Double-check important results. This is an educational estimate, not professional advice — and where it uses a rate, bracket or fee, those change over time. Verify anything you'll rely on, especially in legal, financial, tax or medical matters, and read our full disclaimer. Think a result is wrong? Tell us so we can fix it.
How to Use This Calculator
Choose how many children the order covers and enter the paying parent's gross monthly income. The calculator applies Nevada's tiered percentage formula and returns the presumptive base monthly obligation.
This is the starting figure the guidelines produce. A Nevada court can adjust it for shared custody, health-insurance and childcare costs, low income, and other factors, so treat the result as an estimate of the base only.
How the Calculation Works
Since 2020, Nevada bases child support on the obligor's gross monthly income using tiered percentages that decrease as income rises. For one child the tiers are 16%, 8% and 4% across the three income bands. Two children use 22%, 11% and 6%; three use 26%, 13% and 6%; four use 28%, 14% and 7%; five use 30%, 15% and 8%.
The calculator applies each percentage only to the income within its band and adds the results, which is how a tiered formula works.
1 child: 16% of first $6,000 + 8% of $6,000–$10,000 + 4% above $10,000
Worked Example
For one child with a gross monthly income of $5,000: all of it is within the first band, so the obligation is 16% × 5,000 = $800 per month.
If income were $8,000, it would be 16% × 6,000 + 8% × 2,000 = 960 + 160 = $1,120 per month, because the amount above $6,000 is charged at the lower 8% rate.
Assumptions and Limitations
- Uses Nevada's 2020 NAC 425 tiered percentages of gross monthly income
- Returns the presumptive base obligation only
- Omits adjustments for shared custody, insurance, childcare and low income
- Not legal advice — the court sets the official amount

Nevada parents, and the attorneys and mediators helping them, use this to estimate support from the obligor's gross monthly income. Run it while planning a separation, preparing for mediation, or sanity-checking a proposed figure.

How is child support calculated in Nevada?
Since 2020, as a tiered percentage of the paying parent's gross monthly income. For one child it is 16% of the first $6,000, 8% of $6,000–$10,000, and 4% above $10,000, with higher percentages for more children.
What is the Nevada child support percentage?
It depends on the number of children and income band. One child starts at 16%, two at 22%, three at 26%, four at 28% and five at 30% on the first $6,000, with lower rates on higher income bands.
Does shared custody change Nevada child support?
Yes. This tool gives the base obligation; Nevada courts adjust for shared physical custody and other factors, which can significantly change the final amount. Consult the court or an attorney.
Is this the exact amount I'll pay?
No. It estimates the presumptive base obligation. The court applies adjustments for insurance, childcare, low income and custody arrangements, so the official figure can differ.
What income does Nevada use?
Gross monthly income of the obligor under the current guidelines. Definitions of income and available deductions are set by Nevada law, so a family-law professional can confirm what counts.
