How is child support calculated in Alaska?
Alaska applies a percentage-of-obligor-income model. The non-custodial parent typically pays a set percentage of gross or net income that scales with the number of children, and the exact percentages vary by state — see the statutory rates listed above for Alaska. The custodial parent's income is generally not factored.
The calculation typically adjusts for: (1) work-related childcare, (2) the child's portion of health-insurance premiums, (3) extraordinary medical expenses, and (4) parenting time when overnights cross a state-defined threshold (e.g., 20%–40% depending on jurisdiction). Pre-existing support orders for other children, alimony paid, and mandatory retirement contributions also reduce gross income before the formula applies.
Guideline figures are presumptive — judges may deviate upward or downward when applying them would be unjust given the child's needs, the parents' resources, or other relevant factors. Alaska courts retain final discretion. Always confirm the current guideline tables and worksheet with the Alaska child support agency or family court.

Alaska is one of just six remaining states using the Percentage of Obligor Income model (under Civil Rule 90.3): 20% of the noncustodial parent's adjusted income for one child, 27% for two, 33% for three, escalating thereafter. Alaska is unique in considering the Permanent Fund Dividend (annual oil-revenue payment to all residents) as income for support purposes. The Child Support Services Division enforces orders statewide; rural cases often require teleconferenced hearings.

Alaska child support — frequently asked questions
How is child support calculated?
Most states use the income shares model, which estimates what parents would have spent on the child if they lived together, then divides that based on each parent's income share. Factors include gross income, number of children, custody arrangement, and healthcare/childcare costs.
Can child support be modified?
Yes. Either parent can request a modification if there is a substantial change in circumstances, such as a significant income change (increase or decrease), job loss, change in custody arrangement, or changes in the child's needs.
At what age does child support end?
In most states, child support ends at age 18 or high school graduation (whichever comes later). Some states extend support to age 19-21 or through college. Court orders may specify different end dates based on individual circumstances.
