How to Use the Nevada Child Support Calculator
Enter what you know and press Calculate Estimate. The calculator follows NAC Chapter 425, the Nevada regulations that set the child support guidelines.
- Enter each parent's gross monthly income as Parent A and Parent B.
- Choose the number of children and the parent the children live with most of the time.
- Enter the overnights a year the children spend with the other parent. If each parent has at least 146 nights, the calculator treats it as joint physical custody.
- Add monthly child care if any, and say which parent pays it.
Your numbers are sent with the form, not placed in the page address, and this site does not store them. This is a planning estimate. A Nevada court decides the actual amount.
Nevada Child Support Laws and Changes for 2026
Looking for new child support laws in Nevada for 2026? The regulations we used are the current NAC Chapter 425 on the Nevada Legislature website (revised April 13, 2026). The percentage formula in NAC 425.140 was added in a regulation that took effect on February 1, 2020, and we did not find a later change to the formula in that text. Nevada's low-income schedule is republished each year by the Administrative Office of the Courts, on or before March 31 (NAC 425.145). That schedule is not built into this calculator. This page will be updated if the formula changes.
A change in the guidelines does not automatically change an existing order. A parent generally has to ask the court to modify it.
How Nevada Calculates Child Support
Nevada does not use an income shares model. Under NAC 425.140 the base obligation depends on the paying parent's monthly gross income and the number of children:
- Find the paying parent's monthly gross income.
- Apply the percentages for the number of children to each part of that income (the first $6,000, the part from $6,000 to $10,000, and the part above $10,000).
- Add the three amounts. This is the base child support obligation.
- The court can adjust it for the child's needs and the parents' economic circumstances, with written findings.
The other parent's income does not change the base obligation when one parent has primary physical custody.
The Nevada Percentage Schedule
These are the percentages in NAC 425.140, applied to each slice of the paying parent's monthly gross income:
| Number of children | First $6,000 of monthly income | $6,000 to $10,000 | Above $10,000 |
|---|
| 1 | 16% | 8% | 4% |
| 2 | 22% | 11% | 6% |
| 3 | 26% | 13% | 6% |
| 4 | 28% | 14% | 7% |
| Each additional child | add 2% | add 1% | add 0.5% |
Example for one child and $8,000 of monthly income: 16% of $6,000 is $960, plus 8% of $2,000 is $160, for a base obligation of $1,120.
Joint Physical Custody in Nevada
When the parents have joint physical custody, the obligation of each parent is calculated on their own income. The two obligations are then offset, and the parent with the higher obligation pays the other the difference (NAC 425.115(3)). If each parent has joint physical custody of some but not all of the children, the obligations are offset based on the number of children each owes support for.
This calculator treats a parent having the children at least 146 nights a year (40%) as joint physical custody. The statute that defines joint physical custody is not part of the regulations we reviewed, so please confirm the threshold that applies to your case.
Nevada Child Support Examples
In each example the children live mostly with Parent B. Amounts are monthly and come from this calculator.
Example 1: One child
A earns $5,000 a month. 16% of $5,000 is $800 a month. B's income does not change it.
Example 2: Two children and higher income
A earns $12,000. 22% of the first $6,000 is $1,320, 11% of the next $4,000 is $440 and 6% of the last $2,000 is $120. A pays $1,880 a month.
Example 3: Child care
A earns $7,000, B earns $3,000, one child, and B pays $400 a month in child care. A's base obligation is $1,040. A's 70% share of child care is $280. A pays $1,320 a month.
Example 4: Joint custody
A earns $7,000 and B earns $3,000, two children, with 182 nights with A and 183 with B. A's obligation is $1,430 and B's is $660. A pays the difference of $770 a month.

What Counts as Income in Nevada
Nevada defines gross income broadly in NAC 425. It includes wages and salary, commissions and bonuses, self-employment income, rental income, alimony and many other sources, whether or not taxable. It does not include child support received, foster care payments, SNAP benefits, cash benefits paid by a county, supplemental security income, or compensation for losses not meant to replace income. The court can impute income to a parent who is underemployed or unemployed without good cause, after considering the parent's circumstances.
Frequently Asked Questions About Nevada Child Support
Is this the official Nevada child support calculator?
No. ChildSupportCalculator.xyz is an independent tool and is not affiliated with the State of Nevada or its courts. It applies NAC Chapter 425. A court sets the actual amount.
How is child support calculated in Nevada?
Nevada applies percentages to the paying parent's monthly gross income, based on the number of children. For one child the percentages are 16% of the first $6,000, 8% of the next $4,000 and 4% of the rest.
Are there new child support guidelines in Nevada in 2026?
We used NAC Chapter 425 as revised April 13, 2026. The percentage formula dates from a regulation effective February 1, 2020, and we did not find a later change. This page will be updated if it changes.
Does the other parent's income matter in Nevada?
Not when one parent has primary physical custody. The base obligation is set from the paying parent's income. With joint physical custody, each parent's obligation is calculated and offset.
What is joint physical custody for child support in Nevada?
Each parent's obligation is calculated on their own income and the higher one pays the difference. This calculator uses 146 nights a year (40%) as the threshold, which you should confirm against the statute.
How are child care costs handled in Nevada?
The court must consider reasonable child care costs paid by either or both parents and make an equitable division. This estimate divides them by income share.
Is there a low-income schedule in Nevada?
Yes. If the paying parent's economic circumstances limit ability to pay, the court uses a low-income schedule based on the federal poverty guidelines, published each year by the Administrative Office of the Courts. It is not built into this calculator.
Can a Nevada order be modified?
Yes. A parent can ask the court to modify the order. Incarceration or involuntary institutionalization of 180 consecutive days or more is treated as a substantial change in circumstances.
Does the Nevada calculator need my personal details or a login?
No. This site needs no login and does not store your numbers.
