Quick answer: Nevada does not use an income-shares table. Its guidelines (NAC 425.140, in effect since February 1, 2020) apply tiered percentages to the obligor’s gross monthly income: for one child, 16% of the first $6,000, 8% of the part from $6,000 to $10,000 and 4% of the part above $10,000; for two children 22%, 11% and 6%; for three children 26%, 13% and 6%; for four children 28%, 14% and 7%; and for each additional child 2%, 1% and 0.5% more. There is no income cap. The parent with primary physical custody is the obligee; with joint physical custody, each parent’s obligation is calculated and the higher one pays the difference. If the court finds the obligor’s economic circumstances limit his or her ability to pay, it uses the annual low-income schedule based on the federal poverty guidelines, which for 2026 covers $998 to $1,995 of gross monthly income. Child care and medical support are added separately, the court may adjust the obligation for the factors in NAC 425.150, and a 20% change in a parent’s gross monthly income is a changed circumstance requiring review.

What this calculator checks
The calculator uses the NAC 425.140 tiers and the official 2026 low-income schedule, and was checked against an independent re-implementation and 60 cells of the official schedule. It does not apply deviations, child care or medical support allocations, or split custody, and it does not compute the court’s adjustment factors.
Child support across Nevada
The guidelines apply in every Nevada district court, from Las Vegas, Henderson, Reno, North Las Vegas, Sparks or Carson City. The court must state findings and the guideline amount if it sets support above or below the guidelines.
