Nevada Child Support Calculator

Nevada uses a tiered percentage-of-income model under NAC 425.140 (the Nevada Administrative Code child support guidelines). The base obligation is found by applying marginal percentages to three brackets of the paying parent's gross monthly income: the first $6,000, the portion from $6,000 to $10,000, and any portion above $10,000. For one child the rates are 16% / 8% / 4%; for two children 22% / 11% / 6%; for three children 26% / 13% / 6%; and for four children 28% / 14% / 7%. For each additional child beyond four, add 2% to the first bracket, 1% to the middle bracket, and 0.5% to the top bracket. Work-related childcare and the child's health insurance premiums are then added on top of that base amount.

Gross income in Nevada includes income from all sources including wages, salaries, commissions, bonuses, tips, self-employment income, dividends, severance pay, pensions, interest, trust income, annuities, Social Security benefits, unemployment benefits, disability insurance, workers' compensation, and spousal support received. Under NAC 425 the court may impute income to a parent who is willfully unemployed or underemployed without good cause.

Nevada's base formula under NAC 425.140 applies tiered percentages to the paying parent's income and does not build parenting time into the base amount the way an income-shares state does. However, when parents share physical custody (each has the child at least 40% of the time), NAC 425.115 applies an offset: each parent's tiered obligation is calculated and the parent with the higher obligation pays the difference. Parenting time can also support a deviation from the presumptive amount.

Yes, either parent can petition to modify child support. Under NAC 425 a review is available every three years, or sooner when there has been a change in circumstances. A change of 20% or more in the paying parent's gross monthly income is considered a substantial change that justifies modification. Common reasons include income changes, changes in custody arrangements, changes in childcare or medical costs, or a child aging out of the order.

In Nevada, child support continues until the child turns 18, or until 19 if the child is still enrolled in high school. Support may continue past those ages for a child with a disability that prevents self-support. Nevada courts generally cannot order parents to pay for college as part of a standard child support order.

Yes. Under NAC 425, work-related childcare costs and the cost of health insurance for the child are treated as add-ons to the base percentage obligation. This calculator adds those monthly amounts on top of the percentage of the paying parent's income to give a more complete estimate of the total monthly support figure.

This calculator provides an estimate based on the Nevada child support guidelines under NAC 425.140. Actual court-ordered support may differ because NAC 425.145 provides a separate low-income schedule (tied to the federal poverty guidelines) when the paying parent's economic circumstances limit their ability to pay, and judges may deviate under NAC 425.150 based on factors including the cost of the child's special needs, the relative income of both households, and shared physical custody.
