Hawaii has no statutory alimony formula
Hawaii has no statutory alimony formula, so this figure uses the AAML national guideline (30% of the payor's gross income minus 20% of the payee's, capped at 40% of combined income) purely as a ballpark. The figure below is an estimate to give you a ballpark — a Hawaii judge decides the actual amount and duration using the factors listed beneath the calculator. About this method.

Eligibility: No minimum marriage length; eligibility turns on need and the other party's ability to pay, assessed against the statutory factors in HRS § 580-47(a).
Factors Hawaii Courts Weigh
- •Financial resources of the parties
- •Ability of the party seeking support and maintenance to meet his or her needs independently
- •Duration of the marriage
- •Standard of living established during the marriage
- •Age of the parties
- •Physical and emotional condition of the parties
- •Usual occupation of the parties during the marriage
- •Vocational skills and employability of the party seeking support and maintenance
- •Needs of the parties
- •Custodial and child support responsibilities
- •Ability of the party from whom support is sought to meet his or her needs while meeting the needs of the party seeking support
- •Probable duration of the need of the party seeking support and maintenance
- •Other factors measuring the financial condition in which the parties will be left as a result of the action
How Hawaii Alimony Works
- •Hawaii has no statutory or guideline formula for the amount of alimony (called 'spousal support and maintenance'). The family court sets amounts that 'appear just and equitable' after weighing the statutory factors in HRS § 580-47(a).
- •Temporary (pendente lite) support under HRS § 580-9 is likewise discretionary — the court makes orders it deems fair and reasonable; the same factor analysis guides interim awards. There is no temporary-support equation.
- •Duration is discretionary: the court may order support for an indefinite period or until further order of the court. Where support is rehabilitative, it generally lasts long enough for the recipient to complete training/education plus secure appropriate employment.
- •Marital fault (e.g., adultery) is generally not a listed factor and typically does not drive the amount or duration of an award.
- •HRS § 580-47 directs the court to weigh need against ability to pay across the statutory factors; it sets no percentage or dollar formula. Child support, by contrast, uses the HRS § 576D-7 guidelines.
This is an estimate for educational purposes only, not legal advice. Alimony is highly discretionary; a Hawaii judge can order a different amount or duration. Consult a licensed Hawaii family-law attorney about your situation. See the official Hawaii resource.
How Hawaii Calculates Alimony
Hawaii addresses spousal support under Haw. Rev. Stat. § 580-47. It uses a guideline equation that takes a percentage of the payor's gross income and subtracts a percentage of the payee's gross income, with statutory caps. The calculator above applies that equation to your figures and shows each step.
Unlike child support, alimony is one of the most discretionary areas of family law. Even in states with a guideline equation, the figure is a starting point a judge can adjust after weighing the statutory factors, the length of the marriage, and each spouse's needs and ability to pay. Treat any number here as an informed estimate, not a guaranteed award.

How Long Alimony Lasts in Hawaii
Under the AAML national guideline, duration is a share of the marriage length that rises with the length of the marriage; marriages of 20+ years may receive indefinite support. This is an illustration, not a state durational rule.
What Counts as Income
Hawaii's calculation uses each spouse’s gross income — earnings before taxes, including wages, bonuses, commissions, self-employment income, and many recurring sources. Courts can also impute income to a spouse who is voluntarily unemployed or underemployed, meaning support can be based on what a spouse could earn rather than what they currently do. Use your most recent pay stubs and tax return for the most accurate estimate.
Eligibility & Modifying an Order
No minimum marriage length; eligibility turns on need and the other party's ability to pay, assessed against the statutory factors in HRS § 580-47(a).
Alimony orders can usually be modified when there is a substantial change in circumstances — for example, a significant change in either spouse's income, the recipient's remarriage or cohabitation, retirement, or the payor's loss of employment. The specific rules and any non-modifiable agreements depend on your court order and Hawaii law.
Frequently Asked Questions
Is this Hawaii alimony calculator accurate?
It applies the Hawaii guideline from Haw. Rev. Stat. § 580-47 to the numbers you enter, so it gives a close estimate of a typical guideline award. It is not an official court calculation — a judge can order a different amount after weighing the statutory factors.
Is alimony taxable in Hawaii?
For divorces finalized after December 31, 2018, alimony is not deductible by the payor and is not taxable income to the recipient under federal law. Most states follow the federal treatment, but check Hawaii's current rules for state income tax.
Does cheating affect alimony in Hawaii?
It depends on the state. Some states let courts consider marital misconduct among the alimony factors, while others bar it entirely. Review Haw. Rev. Stat. § 580-47 and speak with a Hawaii attorney about how fault is treated where you live.
Can alimony be changed later?
Usually yes. Alimony can often be modified when there is a substantial change in circumstances — such as a large change in income, the recipient's remarriage or cohabitation, or the payor's retirement — unless your order or agreement makes it non-modifiable.
Disclaimer
This calculator provides estimates for educational purposes only and is not legal advice. Alimony is highly fact-specific and discretionary; the amount and duration a Hawaii court actually orders may differ significantly from any estimate here.
