How Hawaii calculates child support
Hawaii's child support guidelines are established by Haw. Child Support Guidelines (HRS § 576D-7). Hawaii uses the Melson formula, which first reserves a self-support amount for each parent’s own basic needs, then allocates child support from the remaining income (a refined income-shares approach).
This calculator applies the current guideline edition: 2024 Guidelines.
The result is the presumptive guideline amount, the starting point a Hawaii court uses before considering deviation factors. The full line-by-line worksheet, guideline edition, and statutory citation are available in Aequis with a 14-day free trial (credit card required).
Hawaii child support FAQ
How is child support calculated in Hawaii?
Hawaii sets child support under its official guidelines (Haw. Child Support Guidelines (HRS § 576D-7)), which follow the Melson formula. The guideline produces a presumptive monthly amount from the parents' incomes, the number of children, and inputs such as parenting time, childcare, and health insurance costs.
Is this the exact amount a Hawaii court will order?
No. This is an informational estimate of the presumptive guideline amount. Courts can deviate based on statutory factors, and official worksheets may require inputs this calculator does not collect. Always verify against the official guidelines worksheet before relying on any number.
What income counts for child support in Hawaii?
Guidelines generally start from each parent's gross income from most sources, with their own definitions, exclusions, and deductions. This calculator uses gross monthly income; consult Haw. Child Support Guidelines (HRS § 576D-7) for what Hawaii includes.
Do overnights affect child support in Hawaii?
Many jurisdictions adjust the obligation for parenting time once overnights pass a threshold, and this calculator applies Hawaii's guideline treatment of overnights where the guideline provides one. The exact effect depends on Hawaii's formula and the parents' incomes.
