Nevada Child Support Calculator

Nevada calculates child support using a Percentage of Gross Income model under NRS 125B.070. The non-custodial parent pays a set percentage of their monthly gross income depending on the number of children covered by the order: 18% for one child, 25% for two children, 29% for three children, and 31% for four children. For five or more children, the percentage is at least 31% and courts may set a higher amount based on the child's needs and the parent's financial resources. This percentage-based approach creates a direct and predictable relationship between the paying parent's income and the support obligation, making it straightforward for both parents to estimate the likely amount before any formal court proceeding.

Nevada's percentage model focuses on the paying parent's income rather than combining both parents' incomes the way Income Shares states do. The policy rationale is simplicity and enforceability — a single income is easier to verify and update than a two-income calculation, and the percentages are calibrated to represent reasonable child-rearing costs as a share of the paying parent's resources. However, Nevada courts retain discretion to consider the custodial parent's income and financial situation as part of the deviation analysis when the standard percentage would produce an unjust result in either direction.

Nevada's guidelines also establish minimum and maximum support amounts that operate as floors and ceilings on the percentage calculation. At the lowest income levels, the guidelines set a minimum monthly amount to ensure that even low-income parents contribute something meaningful to their child's financial support. At higher income levels, the guidelines cap the obligation so that very high earners do not pay amounts that far exceed the child's actual needs. Courts may award above-cap support for extraordinary expenses or special circumstances, but the cap provides a presumptive ceiling for standard cases.

Nevada defines gross income for child support purposes to include all income from any source before deductions. Wages, salaries, commissions, bonuses, overtime pay, tips, and self-employment net income are all included. Investment income — dividends, interest, capital gains, and rental income — is included as well. Social Security benefits, disability insurance payments, pension distributions, unemployment compensation, and workers' compensation benefits are also counted. Nevada courts are not limited to income that appears on a W-2 or tax return; any regular inflow of funds that enhances the parent's economic capacity is fair game for inclusion in the gross income calculation.

Self-employed parents receive close scrutiny in Nevada child support proceedings. Courts examine gross business receipts and deduct only legitimate, ordinary, and necessary business expenses to arrive at net self-employment income. Non-cash expenses such as depreciation that reduce paper income without reducing actual cash flow may be added back for support calculation purposes. A self-employed parent who controls their business compensation — by paying themselves a below-market salary and retaining profits in the business — may have income imputed to them based on the business's total earnings capacity rather than the salary they chose to draw.

When a parent is voluntarily unemployed or underemployed, Nevada courts may impute income to that parent at the level they could reasonably earn given their education, work history, occupational skills, and the employment opportunities available in the local market. Courts look at recent employment history, any deliberate choice to leave a position or reduce hours, and whether the unemployment is genuinely involuntary or the result of choices that served to reduce the support obligation. Imputed income is added to the parent's reported income to produce a figure that more accurately reflects their true earning capacity for support calculation purposes.

Nevada's guidelines include income brackets that define minimum and maximum support obligations corresponding to different income levels. At the lower end, Nevada sets minimum monthly support amounts — typically around $100 per month — for parents whose income is below a certain threshold, ensuring that every child receives at least a baseline financial contribution. These minimums recognize that even very low-income parents have an obligation to contribute to their child's support, while also acknowledging that ordering amounts larger than the parent can realistically pay produces orders that will not be complied with and that do not actually benefit the child.

At higher income levels, Nevada's guidelines specify maximum monthly support amounts for each number of children beyond which the standard percentage does not automatically apply. For very high earners, courts evaluate the child's actual needs — education, healthcare, extracurricular activities, standard of living — rather than mechanically applying the percentage to unlimited income. When one parent earns substantially more than is needed to provide the child with a comfortable standard of living, courts have discretion to cap the obligation at an amount that meets the child's demonstrated needs with a reasonable margin, rather than awarding a percentage that would produce a windfall exceeding any legitimate child-rearing purpose.

Nevada's income brackets and caps are periodically reviewed and updated to reflect changes in the cost of living and economic conditions in the state. The Child Support Enforcement Program within the Nevada Division of Welfare and Supportive Services publishes updated guidelines and worksheets that courts and parties use to estimate obligations. Because the caps and minimums are tied to specific dollar thresholds rather than percentages of the poverty line, they require periodic legislative or regulatory adjustment to remain current with inflation and rising costs of living, and parents with older orders may find that current guidelines would produce different results than those applicable when their order was entered.

Nevada's standard percentage model assumes a sole custody arrangement where the non-custodial parent has limited time with the child. When parents share physical custody more equally, courts have the authority — and often the obligation — to deviate from the standard percentage to reflect the reality that both parents are incurring direct costs during their respective custody periods. Nevada does not have a fixed shared-custody formula comparable to those used in Income Shares states, but courts routinely reduce the standard percentage when the non-custodial parent has the child for a substantial portion of the year, often using a cross-credit or proportional reduction approach.

Health insurance for the child is addressed in every Nevada child support order. Courts are required to determine which parent will provide health insurance coverage and to specify that obligation explicitly. When a parent has access to employer-sponsored group health coverage at a reasonable cost, they are typically ordered to maintain that coverage for the child. The cost of the child's health insurance premium is relevant to the deviation analysis — a parent who is paying a significant health insurance premium for the child may argue for a reduction in the cash support obligation to account for this substantial in-kind contribution to the child's wellbeing.

Uninsured and unreimbursed medical costs are addressed separately from the regular monthly support order in Nevada. Courts typically include a provision in the order specifying how these costs will be shared — usually proportionally based on the parents' respective incomes or in equal shares. Dental and vision costs, prescription medications not covered by insurance, and co-payments for medical visits are the most common categories of uninsured expenses. Parents are generally required to provide timely notice and documentation of extraordinary medical costs to the other parent before seeking reimbursement, and disputes about medical cost sharing are among the most frequent post-decree issues in Nevada family courts.

Nevada child support orders may be modified when there has been a substantial change in circumstances since the order was entered or last modified. A change is generally considered substantial if it is ongoing rather than temporary and if it was not reasonably anticipated at the time the existing order was set. Common grounds for modification include a significant and sustained change in either parent's income, a change in the physical custody arrangement, a material change in the child's healthcare or childcare costs, or the aging of the child into different needs. Temporary income fluctuations or short-term job changes typically do not support a permanent modification request.

Nevada also provides for a three-year periodic review of child support orders. Either parent may request a review after three years without having to independently prove a change in circumstances, simply by demonstrating that the current guideline calculation — using current incomes — would differ from the existing order by a specified threshold. This three-year review mechanism ensures that orders remain current with each parent's evolving financial situation and prevents orders from becoming dramatically misaligned with actual income levels over time. The review applies the current guidelines at the time of the review proceeding, which means updates to Nevada's percentages or income brackets also take effect through the review process.

Modification proceedings in Nevada follow the same procedural path as initial support proceedings — a party files a motion, both parents submit financial disclosures, and the court recalculates the obligation using current information. Nevada courts have authority to make modifications retroactive to the date the petition was filed, but not to periods before the petition was served on the other party. This prospective-from-filing limitation creates an incentive for parents to file modification petitions promptly when they experience income changes, rather than waiting to accumulate a larger retroactive adjustment. Retroactive modifications to periods before the petition are generally prohibited under Nevada and federal law.
