Common questions

Nevada child support, answered

How is child support calculated in Nevada?
Nevada bases child support on a percentage of the obligor's monthly gross income under NAC 425.140 (16% of the first $6,000 for one child, tiered above), plus an equitable division of childcare and medical support and any adjustments - the 'total obligation' model added by R139-23, effective July 7, 2025.
My lawyer said I could get more - why does this site disagree?
This calculator shows the presumptive guideline amount under NAC 425. A court can order a different amount by deviating for specific statutory factors (NAC 425.150), and your attorney may be describing a possible deviation, a different income figure, or add-ons like childcare and medical support. The guideline is the starting point, not a ceiling. This tool is information, not legal advice - talk to a licensed Nevada attorney about your specific facts.
What are the Nevada child support percentages?
Of the first $6,000 of monthly gross income: 16% for one child, 22% for two, 26% for three, and 28% for four, with lower marginal rates on income above $6,000 and above $10,000, plus increments for each additional child (NAC 425.140).
Is there a cap on Nevada child support?
No. Nevada removed the presumptive maximum amounts in the 2020 guideline overhaul; the top marginal rate applies to all income above $10,000. A low-income schedule (NAC 425.145) sets reduced amounts for low-income obligors.
Did Nevada child support law change in 2025?
Yes. LCB File No. R139-23, filed and effective July 7, 2025, restructured the guidelines into a 'total obligation' (base support plus an equitable division of childcare and medical support and adjustments) and extended the offset rule to split-primary custody. Note: the codified NAC 425 page has not yet been updated to reflect it.
