Oregon has no statutory alimony formula
Oregon 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 Oregon judge decides the actual amount and duration using the factors listed beneath the calculator. About this method.

Factors Oregon Courts Weigh
- •Duration of the marriage
- •Age of the parties
- •Health of the parties, including physical, mental and emotional condition
- •Standard of living established during the marriage
- •Relative income and earning capacity of the parties (recognizing the wage earner's continuing income as a basis for support distinct from property-distribution income)
- •Each party's training, employment skills and work experience
- •Financial needs and resources of each party
- •Tax consequences to each party
- •A party's custodial and child support responsibilities
- •For compensatory support: the amount, duration and nature of one spouse's significant contribution to the other's education, training, vocational skills, career or earning capacity, and the extent to which the marital estate already benefited from that contribution
- •Any other factor the court deems just and equitable (each category's factor list is non-exhaustive)
How Oregon Alimony Works
- •Oregon has NO statutory formula or percentage for the AMOUNT of spousal support. Under ORS 107.105(1)(d), a court awards an amount of money for a period of time as may be just and equitable, weighing the statutory factors. Any calculator output is an illustrative estimate, not a statutory entitlement.
- •Oregon recognizes three distinct categories of spousal support, which can be combined: (1) transitional support (for education/training to re-enter or advance in the job market), (2) compensatory support (where one spouse made a significant contribution to the other's education, career or earning capacity), and (3) spousal maintenance (need-based, for a specified or indefinite period).
- •There is no statutory duration cap. Spousal maintenance may be ordered for a specified period or indefinitely; long-term marriages with large income disparities are the typical setting for indefinite or long maintenance awards.
- •The statute does not designate gross or net income; Oregon practitioners and courts generally reason from gross income and the parties' overall financial circumstances. This model uses gross income.
- •Spousal support generally terminates on the death of either party unless the judgment states otherwise, and is modifiable on a substantial change in economic circumstances (ORS 107.135) — except compensatory support, which can only be modified on a showing of an involuntary, extraordinary, and unanticipated change reducing the paying spouse's earning capacity. Terminated support can be reinstated under ORS 107.136 within the remaining award duration or 10 years after the terminating judgment, whichever is sooner.
This is an estimate for educational purposes only, not legal advice. Alimony is highly discretionary; a Oregon judge can order a different amount or duration. Consult a licensed Oregon family-law attorney about your situation. See the official Oregon resource.
How Oregon Calculates Alimony
Oregon addresses spousal support under ORS 107.105(1)(d). 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 Oregon
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
Oregon'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
Not every divorce results in alimony. Oregon courts award it when one spouse has a genuine financial need and the other has the ability to pay, judged against the factors above.
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 Oregon law.
Frequently Asked Questions
Is this Oregon alimony calculator accurate?
It applies the Oregon guideline from ORS 107.105(1)(d) 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 Oregon?
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 Oregon's current rules for state income tax.
Does cheating affect alimony in Oregon?
It depends on the state. Some states let courts consider marital misconduct among the alimony factors, while others bar it entirely. Review ORS 107.105(1)(d) and speak with a Oregon 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 Oregon court actually orders may differ significantly from any estimate here. For advice about your situation, consult a licensed Oregon family-law attorney.
