Hawaii Child Support Calculator
Planning estimate for Hawaii child support using a generic gross-income heuristic. Does not implement the state guideline or determine a court order.
Estimate only — these are not official figures
This estimate combines the annual gross amounts entered for the parents, applies 17% for one child plus 5 percentage points per additional child through five, adds child-care and insurance costs, and allocates it by each parent’s income share. The overnight field identifies the modeled payer; it does not implement Hawaii’s guideline. This tool does not implement the state guideline; none is an official guideline amount.
Do not rely on these amounts for budgeting or payment. For exact amounts, check the Hawaii Child Support Enforcement Agency: https://ag.hawaii.gov/csea/.

Key State Information
Melson Formula guideline context: Hawaii’s Child Support Enforcement Agency explains that a person seeking a change may file in Family Court or ask the agency to initiate a modification. An agency request must be in writing, with an application for services unless the stated public-assistance exception applies. See https://ag.hawaii.gov/csea/faqs/orders-processing/. This planning tool does not determine a modification or reproduce the guideline calculation.
Example Calculation
Two possible household arrangements
With two children and annual incomes of $76,000 and $44,000, 225 nights with Parent 1, $8,400 in care and $2,400 in insurance, Parent 2’s modeled share comes to $1,136.67 a month.
Result: Change the inputs to one child, $65,000 and $35,000 income, 165 nights with Parent 1, $3,600 care and $1,800 insurance: Parent 1 is the modeled payer at $1,213.33 monthly. These are not Hawaii guideline amounts.
