Hawaii Child Support Calculator | Guidelines

By Child-Support.com Staff – Last updated

The Hawaii Child Support Calculator is a form through which you can estimate the amount of child support you may have to pay or may be able to receive. The calculator uses the guidelines promulgated by the Hawaii Family Court and they are the same guidelines used by the court and the Child Support Enforcement Agency when establishing child support orders. Keep in mind that the worksheet only provides an estimate of the amount of child support you may owe and that the court or agency may change the amount due to various factors that may be unique to your situation.

  • Monthly Gross Income from all sources
  • Monthly Net Income (from Table of Incomes)
  • Add together to get the total income
  • Figure out the percentage for each parent by dividing each parent’s monthly net income by the total income

Step 3: Enter the following information regarding the child support need:

  • Enter $385 x the number of children to get the base primary support
  • Plus Monthly Child Care Expense (to allow custodial parent to work or attend voc. ed. or training)
  • Plus Monthly Health Insurance Expense (for the child(ren) and paid by parents)
  • If no insurance, use Cash Medical support amount (10% of Net Income)
  • Add these amounts to get the Primary Child Support Need

Step 4:  Enter the following information for the standard of living adjustment:

  • Enter SOLA income for each parent (from Table of Incomes)
  • Less Primary Child Support Need
  • Remaining SOLA Income (if result is negative enter 0 )
  • SOLA Percentage (10% per child, up to 30% maximum)
  • SOLA Amount (Percentage x Remaining SOLA income)
  • Child Support Calculation: SOLA Amount plus Primary Child Support Need

Step 5: Calculate the parent support obligation by multiplying the Child Support Calculation by the parent’s percentage income from above

Step 6: Subtract any credits for child care expenses and health insurance payments to get the remaining child support obligation
