How Nevada calculates child support
- Support is a percentage of the paying parent’s gross monthly income, in three tiers: for one child 16% of the first $6,000, 8% of income from $6,000 to $10,000 and 4% above $10,000.
- For two children the tiers are 22%, 11% and 6%; for three 26%, 13% and 6%; for four 28%, 14% and 7%; each additional child adds 2%, 1% and 0.5%.
- With joint physical custody (each parent has the children at least 40% of the time), each parent’s amount is calculated and the parent with the higher amount pays the difference.
- If the court finds that a low-income parent’s circumstances limit their ability to pay, it uses the low-income schedule the Administrative Office of the Courts publishes each year (2026: monthly incomes from $998 to $1,995).
- The court then adds a share of child care and medical support and may adjust for the factors in NAC 425.150.
What the calculator asks
- How many children is the support for?
- What physical custody do you have, or are you asking for?
- Your gross income per month
- The other parent’s gross income per month
- Does a child receive Social Security benefits because of a parent’s disability or retirement?
It never asks for names, Social Security numbers or account numbers, and your answers are not saved.
What the estimate leaves out
- Child care costs the court divides between the parents (NAC 425.130)
- Medical support, including health insurance premiums (NAC 425.135)
- Adjustments for the factors in NAC 425.150, such as special educational needs, other children a parent supports, or transportation for visits
- Children in different custody arrangements (for example, each parent has primary custody of a different child)
- A child’s Social Security benefit
When a situation is outside what the calculator covers, it says so and points you to the official worksheet instead of guessing.
