The Alaska child support calculator is the official tool used to determine the amount of child support under Alaska's Civil Rule 90.3. This calculator applies the Percentage of Income Model to calculate child support payments based on the noncustodial parent earns income and custody arrangements.
Calculator Overview
The Alaska child support calculator is accessible through the Alaska Child Support Services Division website at webapp.state.ak.us/cssd/guidelinecalc. This web-based tool provides estimates based on Civil Rule 90.3 guidelines but does not create binding obligations. Courts and CSED may adjust the final amount of child support based on individual circumstances.
Child Support Percentage Rates
Alaska uses standardized percentages of adjusted annual income to determine child support obligations:
Number of Children | Percentage of Income | Example: $60,000 Annual Income |
1 child | 20% | $1,000 per month |
2 children | 27% | $1,350 per month |
3 children | 33% | $1,650 per month |
4 children | 36% | $1,800 per month |
5+ children | +3% per additional child | Varies based on total |
Income Calculation Process
The Alaska child support calculator begins with determining gross annual income from all sources. This includes wages, self-employment income, unemployment benefits, Social Security, military pay, rental income, and investment earnings. The calculator then applies allowable deductions to determine adjusted annual income.
Allowable Deductions
The calculator permits specific deductions from gross income:
- Federal income taxes owed (not withheld amounts)
- State unemployment insurance premiums
- Mandatory retirement contributions
- Health insurance premiums for children
- Work-related childcare expenses
- Child support for children from prior relationships
- Union dues
- Life insurance premiums (maximum $1,200 annually)
Income Documentation Requirements
Parents must provide comprehensive documentation including tax returns, pay stubs, benefit statements, and employment verification. Self-employed individuals need business records, profit and loss statements, and detailed financial documentation covering the most recent 12-month period.
Custody Arrangements and Calculations
The Alaska child support calculator applies different calculation methods based on physical custody arrangements.
Primary Physical Custody
When one parent has physical custody for 70% or more of the time (256+ overnights annually), the calculator uses the standard percentage method. The amount of child support is calculated by multiplying the noncustodial pa\ent's adjusted annual income by the applicable percentage and dividing by 12 for monthly payments.
Shared Physical Custody
For arrangements where each parent has 30% or more custody time (110+ overnights annually), the calculator considers both parents' incomes and parenting time percentages. The calculation involves determining each parent's theoretical obligation, finding the difference, and multiplying by 1.5. The parent with the higher obligation pays the adjusted amount.
Complex Custody Arrangements
Divided custody (multiple children with each parent having primary custody of at least one) and hybrid custody (mixed shared and primary arrangements) require specialized calculations using additional forms and complex mathematical procedures.
Required Forms and Documentation
The Alaska child support calculator works in conjunction with specific court forms:
Custody Type | Required Forms |
Primary Physical Custody | Form DR-305 (Child Support Guidelines Affidavit) |
Shared Physical Custody | Form DR-305 + Form DR-306 (Shared Custody Calculation) |
Divided Physical Custody | Form DR-305 + Form DR-307 (Divided Custody Calculation) |
Hybrid Physical Custody | Form DR-305 + Form DR-308 (Hybrid Custody Calculation) |
Special Circumstances and Adjustments
The Alaska child support calculator accommodates various special circumstances that may affect the final calculation.
Extended Visitation Credits
Noncustodial parents with extended visitation periods exceeding 27 consecutive days may qualify for credits up to 75% of the regular support amount during that period. Documentation of the visitation schedule and actual dates is required.
Low-Income Adjustments
For parents with adjusted annual income below $30,000, the calculator may apply the lower of actual income or $7,500 as the base calculation amount.
Imputed Income
When a parent is voluntarily unemployed or underemployed, the calculator may use potential earning capacity rather than actual income. Factors include employment history, education, available job opportunities, and physical capacity to work.
Minimum Support Requirements
Alaska requires a minimum monthly child support payment of $50 for all children covered by an order, regardless of the calculated amount.
Medical Support Calculations
Beyond basic child support, the alaska child support calculator includes medical support obligations. Parents must provide health insurance when available at reasonable cost (typically 5% or less of adjusted annual income). The calculator includes credits for parents paying children's health insurance premiums and provisions for sharing uninsured medical expenses.
Calculator Limitations
The child support calculator provides estimates only and includes several important limitations. The tool cannot account for extraordinary medical expenses, special educational needs, geographic cost variations, or unique family circumstances. Courts may deviate from calculator results when unusual circumstances make the standard calculation inappropriate.
Modification Considerations
This calculator helps determine when modifications may be appropriate. Alaska presumes a material change in circumstances exists when new calculations differ by 15% or more from the current order. Common triggers include significant income changes, custody arrangement modifications, or changes in children's needs.
Professional Assistance
While the child support calculator provides useful estimates, complex situations may require professional assistance. CSED caseworkers can provide calculation guidance and form completion assistance. Family law attorneys may be necessary for cases involving self-employment income, custody disputes, or requests for deviations from standard guidelines.
Accessing Calculator Results
Users of the calculator should verify they are using the current version of Civil Rule 90.3 that applies to their case. Different rule versions may produce different results based on when the original order was established. The calculator requires selection of the appropriate rule version before beginning calculations.
Data Security and Privacy
The Alaska child support calculator also maintains confidentiality of personal financial information entered during calculations. The system uses secure connections and does not permanently store calculation data. Users should ensure they are accessing the official calculator through the verified Alaska state government website.
Additional Resources
Parents seeking assistance with the Alaska child support calculator can contact CSED during business hours (10:00 AM - 3:00 PM, Monday through Thursday) or access online resources through the Alaska Courts Self-Help Center. The calculator serves as a foundational tool for understanding potential child support obligations under Alaska law while recognizing that individual circumstances may require additional consideration and professional guidance.
