Child Support Calculator in Hawaii: What You Should Know
Hawaii is one of three states using the Melson Formula for child support, which is more involved than the income shares model most states apply. The formula protects a self-support reserve for each parent first, then funds the children's basic needs, and finally adds a standard-of-living adjustment when income is left over. Because each parent's basic needs come off the top, the result responds closely to what the parents can actually afford. Hawaii has no statutory income cap, so support scales with income through the standard-of-living component.
Key point: Hawaii applies the Melson Formula, setting aside each parent's basic needs before support is calculated and adding a standard-of-living allowance for higher incomes.

Child Support in Hawaii - Frequently Asked Questions
How is child support calculated in Hawaii?
Hawaii uses the Melson Formula to calculate child support. The Melson Formula first reserves a self-support amount for each parent, then calculates the child's share of the remaining income.
Can child support be modified in Hawaii?
Yes. Either parent can request a child support modification if there has been a substantial change in circumstances, such as a significant change in income, change in custody arrangements, or changes in the child's needs. Courts in Hawaii typically require a change of at least 15-20% in the support amount to justify modification.
Does custody arrangement affect child support in Hawaii?
Yes. Parenting time is a significant factor in child support calculations. When a parent has the children for a substantial portion of time (typically 40% or more overnights per year), child support is adjusted to reflect the additional direct costs that parent bears.
Is there an income cap for child support in Hawaii?
Hawaii does not set a specific income cap in its child support formula. However, courts have discretion to deviate from the guideline amount in cases with very high incomes.
How long does child support last in Hawaii?
Child support in Hawaii typically continues until the child turns 18 or graduates from high school, whichever is later. Support may continue longer if the child has a disability or if the parents agree to extend support for college expenses.
