Child Support in Hawaii: How It's Calculated
Hawaii uses the Melson Formula to determine child support obligations. This guide walks through how the formula works, what factors Hawaii courts consider, and how to modify or enforce an order — with links to official Hawaii resources.
Melson Formula in Hawaii
Hawaii uses the Melson Formula, which first ensures both parents can meet their own basic needs, then calculates the child's primary support need, and finally allocates a share of remaining income as a standard-of-living adjustment for the child.
Hawaii's child support guidelines reflect the state's elevated cost of living. The Melson Formula's self-support reserve in Hawaii is set based on local poverty guidelines and cost-of-living factors. Hawaii also has some of the highest standard-of-living adjustment percentages in the country, meaning children are more likely to benefit when parents have surplus income.
Key Factors Hawaii Courts Consider
- Both parents' gross income
- Self-support reserve for each parent
- Primary support need for the child
- Standard of Living Adjustment (SOLA) on remaining income
- Child's health insurance and medical costs
- Work-related childcare costs
- Parenting time arrangements

Step-by-Step: How Hawaii's Formula Works
Here is how Hawaii applies the Melson Formula to calculate a child support obligation, step by step:
1. Determine each parent's net income
The court first calculates each parent's net income — gross income minus taxes, mandatory deductions, and certain allowable expenses. This becomes the foundation for the Melson Formula used in Hawaii.
2. Reserve a self-support amount for each parent
Unlike most states, Hawaii first subtracts a self-support reserve from each parent's income based on the federal poverty level. This ensures neither parent is pushed below subsistence before child support is calculated.
3. Calculate the child's primary support need
After the self-support reserve, the court determines the child's primary support need — the basic costs of food, shelter, clothing, and other necessities. This amount is drawn from Hawaii's support schedule.
4. Apply the Standard of Living Adjustment (SOLA)
Any remaining income after self-support and primary support is subject to a Standard of Living Adjustment. A percentage of each parent's surplus income is added to the support obligation, reflecting the child's right to share in their parents' economic circumstances.
5. Allocate between parents
The total obligation is divided between the parents in proportion to their respective incomes, after accounting for parenting time adjustments and any add-ons for health insurance or childcare.
