Nevada Child Support
The formula lives in a regulation. So it's computed here — as written.
The obligor's gross monthly income drives tiered percentages across three bands — the first $6,000, the portion to $10,000, and everything above — by number of children, with each additional child adding its own increments. The schedule is NAC 425.140, a regulation adopted under NRS 425.620's delegation, and this platform renders that provenance honestly: regulation under delegation, with the AOC's annual low-income schedule as the published instrument beneath it.
Regulation verified at render: the stored official text of NAC 425.140 carries the tier needles — this calculator computes against that verified text (NAC-425.140-2025-codification), and cites it as what it is: a REGULATION under the NRS 425.620 delegation.
The inputs, organized (NAC 425 and its delegation)
The obligor's GROSS monthly income
NAC 425.025 defines gross income — salary and wages, investment and business income, benefits and the rest of the inclusion list; child support received, foster-care payments, SNAP and SSI stay OUT. Gross, not net, drives the Nevada tiers.

The NAC 425.140 tier schedule
Percentages of gross monthly income across three bands (the first $6,000 · over $6,000 to $10,000 · above $10,000), by number of children — 16/8/4 for one child, scaling to 28/14/7 for four, plus 2/1/0.5 points per additional child.

The low-income schedule (annual instrument)
When total economic circumstances limit ability to pay, the AOC's annually published low-income schedule controls (NAC 425.145, keyed to the federal poverty guidelines) — an official instrument this platform stores byte-pinned and routes to, never re-derives.

Deviation factors
Special educational needs, legal support obligations for others, contributed services, public assistance, transportation costs, relative household income, other child expenses, and ability to pay — the NAC 425.150 grounds; deviations take findings.

Why a regulation sets the number
NRS 425.620 delegates the guidelines to regulation — Nevada's support math lives in the Administrative Code, reviewed on the statute's own cycle. This platform renders that provenance honestly: regulation under delegation, the first such engine on the platform.
NRS 425.620
Nevada courts apply NAC 425.140's tiers to the obligor's gross monthly income; this engine computes the base obligation exactly as the regulation states it, shows each band's arithmetic, names the low-income instrument and the deviation grounds, and is legal information — the court's own determination controls.
Authority locked — retrieved from the hash-pinned corpus
Gross income is the real work.NAC 425.025 defines what counts (and what never does: child support received, SNAP, SSI). The low-income schedule controls when total economic circumstances limit ability to pay (NAC 425.145 — the 2026 AOC instrument, stored byte-pinned); deviations take NAC 425.150 findings; and where parents share joint physical custody, Nevada court practice offsets each parent's obligation — compute each side here; the court controls the offset.
