Understanding Alaska's Child Support Formula
Alaska uses the Percentage of Income model, one of the simpler child support approaches in the United States. The court converts the paying parent's gross monthly income to net income by applying a 76% factor that accounts for estimated taxes and mandatory payroll deductions. That net income figure is then multiplied by a fixed percentage that increases with each additional child:
| Children | % of Net Income | Monthly at $5,000 gross |
|---|---|---|
| 1 child | 20% | $760/mo |
| 2 children | 27% | $1,026/mo |
| 3 children | 33% | $1,254/mo |
| 4 children | 37% | $1,406/mo |
| 5 children | 40% | $1,520/mo |
Alaska caps the paying parent's net income at $10,000/month for guideline calculations. A parent earning above approximately $13,158/month gross will have their obligation calculated from the cap rather than their actual income. Courts retain discretion to order additional support above the cap for high earners in cases involving extraordinary expenses.
Sample Alaska Child Support Calculation

Actual court orders in Alaska may also include health insurance premiums, childcare costs, and extraordinary expenses on top of the guideline base. Average awards in Alaska range from $450–$1,000/month across all income levels.
Alaska Child Support, Frequently Asked Questions
What percentage does Alaska use for child support?
Alaska uses 20% of adjusted net income for one child, 27% for two children, 33% for three, 37% for four, and 40% for five or more children. These percentages apply to the paying parent's net income after a 76% conversion factor for taxes.
Is there an income cap for child support in Alaska?
Yes. Alaska caps the paying parent's net income at $10,000/month (approximately $13,158/month gross) for guideline calculations. Income above this threshold does not increase the standard obligation. However, a judge can order additional support beyond the cap in cases where the child has extraordinary needs, such as private schooling, medical conditions, or significant extracurricular costs, or where the paying parent earns substantially more than the cap.
What is the average child support payment in Alaska?
Child support awards in Alaska typically range from $450–$1,000/month based on current data. The actual amount varies significantly depending on both parents' incomes, the number of children, custody arrangements, and whether costs like health insurance or childcare are included in the order. Higher income households and multiple children will produce awards above this range.
Can a Alaska judge order a different amount than the calculator shows?
Yes. The Alaska guidelines produce a presumptive amount — the starting point, but a judge can deviate from it when following the guidelines would be unjust or inappropriate in a specific case. Common reasons for deviation include extraordinary medical or educational expenses, one parent directly paying significant healthcare premiums, a parent's substantial assets or non-wage income, the needs of children from other relationships, or significant travel costs related to custody exchanges.
How do you modify a child support order in Alaska?
Either parent can petition the Alaska court to modify an existing child support order when there has been a substantial change in circumstances. This typically means a significant change in either parent's income (usually 15–20% or more), a change in custody or parenting time, the child developing extraordinary medical or educational needs, or a change in the cost of health insurance. Most states, including Alaska, also allow automatic review every three years if either party requests it, even without proving a substantial change.
When does child support end in Alaska?
In Alaska, child support terminates at: Age 18 or high school graduation, whichever is later. The governing law is AS 25.27.020, administered by the Child Support Services Division (CSSD). If you have an existing order and believe your child is approaching the termination age, contact Child Support Services Division (CSSD) or your family law attorney to confirm the specific end date and ensure a formal termination order is entered.
