Child support in Hawaii is calculated using a multi-step process. First, each parent's monthly gross income is determined, and then their monthly net income is calculated using a Table of Incomes. The parents' percentage share of the total net income is then established. A 'Primary Child Support Need' is calculated based on $455 per child, plus reasonable childcare expenses and health insurance premiums. A 'Standard of Living Adjustment (SOLA)' amount is also calculated, which considers the parents' remaining income after meeting the primary need and applies a percentage based on the number of children (10% for 1, 20% for 2, 30% for 3 or more). The Primary Child Support Need and the SOLA amount are added to determine the total child support. Finally, each parent's total support obligation is determined by their percentage share of net income, with credits given for childcare and health insurance expenses paid.
A substantial change in either parent's income — voluntary or involuntary — can trigger a modification.
Changes in childcare costs or the children's health insurance premiums directly adjust the support amount.
If the custody schedule changes significantly, support can be recalculated under Hawaii guidelines.
Medical conditions, disabilities, or educational needs can justify a departure from the guideline amount.
