Oregon Alimony & Spousal Support (2026)
Unlike child support, Oregon has no fixed formula for how much alimony (spousal support) costs or how long it lasts. A judge decides both based on a list of factors set out in ORS § 107.105. There is no calculator that can honestly give you an exact number here — but the factors below are what actually drives the decision.
What determines alimony in Oregon
Under ORS § 107.105 (Oregon Revised Statutes § 107.105 (Provisions of judgment)), a court considers:
- Duration of the marriage (considered for all three support categories below)
- Transitional spousal support — a party's training and employment skills
- Transitional spousal support — a party's work experience
- Transitional spousal support — the financial needs and resources of each party
- Transitional spousal support — the tax consequences to each party
- Transitional spousal support — a party's custodial and child support responsibilities
- Transitional spousal support — any other factors the court deems just and equitable
- Compensatory spousal support — the amount, duration, and nature of a significant financial or other contribution by one party to the education, training, vocational skills, career, or earning capacity of the other party
- Compensatory spousal support — the relative earning capacity of the parties
- Compensatory spousal support — the extent to which the marital estate has already benefited from the contribution
- Compensatory spousal support — the tax consequences to each party
- Compensatory spousal support — any other factors the court deems just and equitable
- Spousal maintenance — the age of the parties
- Spousal maintenance — the physical, mental, and emotional health of the parties
- Spousal maintenance — the standard of living established during the marriage
- Spousal maintenance — the relative income and earning capacity of the parties, recognizing that the wage earner's continuing income may be a basis for support distinct from income from distributed marital property
- Spousal maintenance — a party's training and employment skills
- Spousal maintenance — a party's work experience
- Spousal maintenance — the financial needs and resources of each party
- Spousal maintenance — the tax consequences to each party
- Spousal maintenance — a party's custodial and child support responsibilities
- Spousal maintenance — any other factors the court deems just and equitable
Good to know
- Oregon recognizes three distinct categories of spousal support — transitional, compensatory, and spousal maintenance — each with its own list of factors, but none of the three has a statutory formula, percentage, or calculator for the dollar amount. The court must designate which category (or combination) applies and make findings on the relevant factors, then set an amount it considers just and equitable.
- Duration is likewise left to the court's judgment on a case-by-case basis; ORS 107.105 does not impose a fixed durational cap tied to marriage length.

Frequently asked questions
Is there an alimony formula in Oregon?
No. Oregon law (ORS § 107.105) does not provide a formula, percentage, or calculator for spousal support amount or duration. Oregon recognizes three types of support — transitional, compensatory, and spousal maintenance — and a judge decides which applies and sets the amount and length based on statutory factors, not a fixed calculation.
What factors determine alimony in Oregon?
The factors depend on which type of support is at issue. Spousal maintenance looks at each party's age, health, standard of living during the marriage, relative income and earning capacity, training, and work experience. Transitional support focuses on training and employment skills needed to reenter the job market. Compensatory support looks at contributions one spouse made to the other's education, training, or career. All three categories also let the court weigh "any other factors" it finds just and equitable.
