Nevada Child Support Calculator

Estimate Nevada child support for 2026 using the Percentage of Income (Capped) guideline model under NAC 425; NRS 125B.070. Enter both parents' incomes and the parenting-time split to see what you may owe or receive.

Nevada uses a flat Percentage of Income model under NAC Chapter 425. Support is calculated as a fixed percentage of the non-custodial parent's adjusted income, graduated percentages of gross monthly income beginning with 16% for one child, with statutory income caps that change the marginal rate above stated income thresholds. The custodial parent's income is generally not factored into the base obligation.

Nevada starts from a flat percentage of the paying parent's gross income, so most parenting time does not change the base number. The big shift is joint physical custody, which Nevada treats as each parent having the child at least 40 percent of the time. When custody is shared at that level, the guideline uses a shared-care offset that compares each parent's obligation rather than charging one parent the full percentage. The estimate on this page is a starting point only, and the official worksheet and a judge decide your real number.

The cost of the child's health insurance premium is treated as an adjustment under Nevada's guidelines in NAC Chapter 425, separate from the base percentage. The premium paid for the child's coverage is generally factored in and shared between the parents in the court's calculation. Uninsured or out of pocket medical costs are typically allocated as well. Because amounts and splits depend on your facts, confirm the figures on the official Nevada worksheet rather than relying on this estimate.

Work-related child care and daycare are listed adjustments under Nevada's guidelines and are not built into the base percentage of income. These costs are generally added on top of the guideline amount and shared between the parents in proportion set by the court. Keep records of what you actually pay so the figure can be verified. This calculator gives a rough estimate, so use the official Nevada worksheet and, if you can, a licensed attorney to confirm how child care is split in your case.

Nevada judges start from the guideline number under NAC 425 and NRS 125B.070, but they may deviate when the guideline amount would be unjust or would not fit the child's needs. Recognized reasons include special needs, the cost of insurance and child care, the relative income of both parents, and other listed factors. The parent asking for a number different from the guideline carries the burden of showing why, and the court must put its specific reasons in the order. Treat this page as an estimate, not legal advice.

Frequently asked questions

How is child support calculated in Nevada?

Nevada uses a flat Percentage of Income model under NAC Chapter 425, with the underlying authority in NRS 125B.070. Support is figured as a set percentage of the paying parent's gross monthly income from any source, starting at 16 percent for one child and using graduated tiers for more children. Nevada's revised 2020 guidelines apply statutory income caps, so the percentage charged on higher income brackets is limited above stated thresholds. The custodial parent's income is generally not part of the base obligation. The Nevada Child Support Enforcement Program oversees this, and this page gives an estimate, not a binding figure.

Is there an official Nevada child support worksheet or calculator I should use?

Yes. Nevada provides an official child support calculator through the Division of Welfare and Supportive Services at dwss.nv.gov, and the controlling rules live in NAC Chapter 425. The on-page tool here is a quick estimate to help you plan, but the official state calculation and the worksheet attached to your court order are what actually control your case. Judges and the Nevada Child Support Enforcement Program rely on the official figures, not a third-party estimate. Always run the official Nevada calculator, and check the result with a licensed attorney before you rely on a number in court.

How does 50/50 or joint physical custody change child support in Nevada?

Nevada recognizes joint physical custody when each parent has the child at least 40 percent of the time, and it changes how the math works. Instead of charging one parent the full percentage of gross income, the guideline uses a shared-care approach that compares each parent's separate obligation and offsets them, so the higher earner usually pays the difference. A roughly equal time split does not erase support if incomes differ. The exact offset comes from NAC Chapter 425 and the official Nevada worksheet, so use this page only as an estimate and confirm the figures with the state calculator.

Does Nevada cap how much child support a high earner pays?

Yes, that is a defining feature of Nevada's revised guidelines. The flat percentage model under NAC Chapter 425 applies graduated percentages of gross monthly income, but statutory income caps limit the percentage charged once income passes stated brackets. In plain terms, the marginal rate steps down above certain income levels rather than rising forever. Because the actual cap thresholds and tier percentages are set by the guideline and updated by the state, you should pull the current figures from the official Nevada calculator. The estimate on this page reflects the general structure but should not be treated as your final number.

How does Nevada count overtime, bonuses, and self-employment income?

Nevada bases support on gross monthly income from any source, so overtime, bonuses, commissions, and self-employment earnings can all be included in the calculation under NAC Chapter 425. For self-employed parents, the court typically looks at gross receipts minus legitimate, ordinary business expenses to reach the true income figure, not just what shows on a tax return. Irregular or seasonal income may be averaged so it fairly reflects what a parent actually earns. Keep pay stubs, profit and loss records, and tax documents ready. This calculator is only an estimate, so verify income inputs against the official Nevada worksheet.

When does child support end in Nevada?

In Nevada, child support generally ends when the child turns 18. If the child is still attending high school at 18, support continues until the child finishes or turns 19, whichever comes first. Support does not stop automatically just because of an age, since arrears and other obligations can remain, and an order tied to multiple children may need recalculation as each child ages out. For a disabled adult child, continuing support may be available beyond the usual cutoff. These rules sit under Nevada law, and this page is an estimate, so confirm your end date with the official guidance or an attorney.

How do I modify or enforce a Nevada child support order?

To change an order, you file a motion in district court or request a review through the Nevada Child Support Enforcement Program. Nevada supports modification when there is a 20 percent variance between your current order and a fresh guideline calculation, or upon a 3-year periodic review. On enforcement, the Nevada CSEP can use immediate income withholding, tax intercept, license suspension, liens, credit reporting, and contempt referrals to collect. Orders generally remain enforceable even when a parent moves out of state. This page only estimates the guideline amount, so use the official Nevada calculator and, ideally, a licensed attorney for any filing.
