Oregon alimony calculator: how courts decide what you'll pay

Last updated 2026-07-09

Does Oregon have an official alimony calculator?

No. Oregon has no statutory formula or worksheet for spousal support. There is no official Oregon alimony calculator the way there is a child support calculator.

That surprises people, because Oregon does have a detailed child support schedule with an actual math sheet ^[1]. Spousal support works differently. Judges have broad discretion, and the legislature kept it that way on purpose. ORS 107.105(1)(d) lists factors the court must consider but assigns no weights or multipliers to any of them ^[2].

Here's what that means for you. Any online "Oregon alimony calculator" you find is an estimate built on rules of thumb, not law. Some borrow formulas from other states. Some are pure guesswork. Treat them as conversation starters, not predictions.

The most useful thing you can do before agreeing to any support number is understand the seven factors Oregon courts actually apply. The next section walks through all of them.

For context on how alimony works nationally, the same discretionary approach shows up in roughly half of U.S. states.

What factors does Oregon law use to determine alimony?

ORS 107.105(1)(d) sets out the factors a court weighs when deciding whether to award spousal support and how much ^[2]. Here they are, out of legal language:

1. The length of the marriage. Often the single biggest factor. A two-year marriage almost never produces long-term alimony. A 25-year marriage almost always gets serious consideration.

2. Each spouse's age and health. A 58-year-old with a chronic condition who left work to raise children sits in a completely different spot than a healthy 34-year-old married for four years.

3. The standard of living established during the marriage. Courts try to avoid one spouse keeping the marital lifestyle while the other drops sharply. Oregon courts use the phrase "avoiding undue economic hardship."

4. Relative income and earning capacity. Current income matters. So does what each person could earn working full-time. If a spouse is voluntarily underemployed, the court can impute income.

5. Training, employment skills, work experience, and time needed to gain education or training. This is where re-entry timelines come in. A parent who hasn't worked in 15 years may need two or three years of transitional support to reach a livable wage.

6. The financial needs and resources of each spouse. What debts does each carry? What assets did each receive in the property split?

7. Each spouse's contribution to the education, training, or career of the other. Put your spouse through medical school? That counts.

Judges weigh all seven together. None automatically overrides the rest. That's what makes prediction hard, and why rigid calculator outputs mislead you.

What are the three types of spousal support in Oregon?

Oregon statute recognizes three types, and the type matters as much as the dollar amount ^[2].

Transitional support helps a lower-earning spouse retrain or get back to work. It's time-limited, usually one to five years, and common in short-to-medium marriages. The point is to bridge a gap, not create a permanent income transfer.

Compensatory support addresses cases where one spouse made major financial or career sacrifices that benefited the other. The classic example is funding a spouse's professional degree. Courts don't award this on autopilot. You have to show the contribution clearly.

Maintenance support is the long-term or indefinite type. It shows up most after long marriages (usually over 15 years) where one spouse has been out of the workforce for years and can't close the income gap through retraining alone. "Indefinite" doesn't always mean permanent. Courts can build in review dates.

Couples negotiate across all three types constantly. A settlement might pair two years of transitional support with a lump compensatory payment for a graduate degree funded during the marriage. You can structure it however you both want, as long as the judge approves. That flexibility is one of the real advantages of settling instead of fighting.

How long does alimony last in Oregon?

Duration depends on which type of support is at issue and how long the marriage lasted. There is no fixed table.

Transitional support usually runs one to five years. The goal is specific: enough time to finish a degree, earn a certification, or rebuild a work history. Once that window closes, support ends.

Maintenance support after a long marriage can stretch much further. Many Oregon counties use a rough informal benchmark: support for about half the length of the marriage in cases where it's ordered. A 20-year marriage might produce 10 years of support. That is not a legal rule, and judges deviate from it often, but it appears frequently enough in Multnomah County and Lane County outcomes that local family law attorneys treat it as a starting point.

For marriages of 25 years or more where one spouse cannot reasonably return to self-sufficiency, indefinite maintenance support is possible. Indefinite means until the receiving spouse remarries, cohabits with a new partner, or a court modifies or ends the order.

Alimony in Oregon terminates automatically on the death of either spouse or the remarriage of the receiving spouse, unless the order says otherwise ^[2]. Cohabitation doesn't automatically end support, but ORS 107.135 lets the paying spouse ask the court to modify or terminate if the recipient's new partner is contributing to household income ^[3].

What does alimony actually cost in Oregon? Realistic payment ranges

Nobody publishes a database of Oregon spousal support awards, so hard statewide averages don't exist. What practitioners report and what public court records show suggests these rough ranges:

Marriage length	Common support type	Typical monthly range	Typical duration
Under 5 years	Rarely awarded	$0 to $500	0 to 1 year
5 to 10 years	Transitional	$500 to $1,500	1 to 3 years
10 to 20 years	Transitional or maintenance	$800 to $2,500	2 to 8 years
20+ years	Maintenance	$1,000 to $4,000+	7 years to indefinite

These are illustrative ranges, not formulas. A surgeon married to a teacher for 12 years produces very different numbers than two mid-income earners with similar jobs. The income gap between spouses is the main driver. When both spouses earn about the same, courts rarely award meaningful alimony regardless of marriage length.

The Tax Cuts and Jobs Act of 2017 changed the federal tax treatment of alimony for divorces finalized after December 31, 2018. Paying spouses no longer deduct alimony. Receiving spouses no longer report it as income ^[4]. That shifts negotiation math: the after-tax cost to the payer is higher now, and so is the after-tax value to the recipient. Run the actual numbers with a tax professional before you settle.

How do you estimate Oregon spousal support without a formula?

Since there's no official calculator, here's a sane way to estimate before you negotiate or file.

Step 1: Calculate the monthly income gap. Subtract the lower-earning spouse's gross monthly income from the higher-earning spouse's. If the gap is under $1,000 a month, courts rarely award meaningful alimony unless the marriage is very long.

Step 2: Assess marriage length. Under seven years, start from the assumption of no maintenance support. Seven to fifteen years, transitional support is likely if there's a real income gap. Over fifteen years, maintenance support is on the table.

Step 3: Identify specific contributions. Did one spouse leave a career? Fund the other's education? Raise kids full-time for years? Each of these pushes the estimate up.

Step 4: Look at what each spouse walks away with from property division. If the lower-earning spouse gets the house, a pension, or big investment accounts, courts adjust support down.

Step 5: Research local norms. Multnomah County, Washington County, and Lane County judges lean different ways. The Oregon State Bar's Lawyer Referral Service can connect you to a family law attorney for a single consultation to reality-check your estimate before you finalize anything ^[5].

Agree with your spouse on a number and you can write it straight into your settlement agreement without ever asking a judge to calculate anything. That's the genuine payoff of an uncontested divorce. You control the outcome instead of handing it to judicial discretion.

Can you modify Oregon alimony after the divorce is final?

Yes. Under ORS 107.135, either spouse can ask the court to modify or terminate a spousal support order after a substantial change in circumstances ^[3].

Oregon courts read "substantial change" to include job loss, a big income increase or decrease, serious illness, retirement, or the recipient beginning to cohabit with someone who helps pay their living expenses. The change has to be real and not something already anticipated when the original order was entered.

One limit matters. If the decree says support is non-modifiable, courts generally honor that language. This comes up when parties trade something in the settlement (say, a larger property share to the payer) for a fixed, locked-in support term. Get that language reviewed carefully before you sign.

Modification is never automatic. You file a motion in the same court that issued the original decree, pay a filing fee (typically $252 in most Oregon circuit courts as of 2024, with slight county variation), and go through a hearing ^[6]. If both spouses agree on the change, you can submit a stipulated agreement instead of litigating.

How does Oregon alimony work in an uncontested divorce?

An uncontested divorce is one where both spouses agree on all terms, including spousal support. In Oregon it runs through the circuit court in the county where either spouse lives, and it costs less and moves faster than a contested case ^[7].

For an uncontested case involving support, the core documents are a Petition for Dissolution of Marriage, a Co-Petition if you file jointly, a Marital Settlement Agreement (sometimes called a Stipulated General Judgment), and a Uniform Support Affidavit if support is ongoing. The Oregon Judicial Department provides these forms at courts.oregon.gov ^[7].

The filing fee for a dissolution of marriage in Oregon is $301 as of 2024, with slight variation by county and whether children are involved ^[6]. That fee doesn't cover attorney help if you hire any.

If you and your spouse have already worked out the support terms, nobody needs to calculate anything for you. You write the agreed amount and duration into the settlement agreement, the judge reviews it to confirm it isn't unconscionable, and the decree adopts your terms. Most judges sign off on negotiated support without changing a word.

DivorceClear's $149 document packet includes a settlement agreement template drafted to Oregon's requirements, which can be a practical starting point once you've agreed on terms. Make sure any support provision states the type, amount, duration, and termination triggers plainly.

If there's any dispute about the number, or the case gets complicated by business ownership, significant debt, or health issues, the uncontested path still works. You'll just want at least a one-hour consultation with a divorce attorney before locking in figures.

Does Oregon alimony differ from child support? How are they related?

They are calculated completely separately, and the order of operations matters.

Oregon child support uses a mandatory formula under ORS 25.275 based on both parents' incomes, the custody schedule, and specific costs like health insurance and childcare ^[1]. There is an actual worksheet, and the result is presumptive. Judges can deviate, but they have to explain why.

Spousal support has no formula and no worksheet, as covered above.

Here's how the two connect. Child support gets calculated first, using both parents' actual incomes. If spousal support is also in play, some practitioners argue that anticipated support should shift the income inputs to the child support calculation, because paying support lowers the payer's disposable income. Oregon courts handle this inconsistently. Some adjust, some don't. If your case involves both, the sequencing is worth a professional look.

Our child support calculator page has more on how Oregon's formula works on that side.

What if my spouse is hiding income or voluntarily underemployed?

Oregon courts can impute income to a spouse who is voluntarily underemployed or unemployed without good cause. If your spouse quit a $90,000 job for a $25,000 job the week before you filed, a court can base support on the $90,000 figure, not the $25,000 one.

The standard is what the spouse could earn with their training, education, and work experience if they made reasonable efforts. Courts look at prior employment history, jobs available in their field in the local labor market, and whether there's a legitimate reason for the drop (serious illness, caring for a disabled child, and the like).

Proving hidden or imputed income usually takes subpoenas, document production, and sometimes a vocational expert or forensic accountant. That is contested divorce territory, outside the scope of a DIY filing. If you think this is happening, talk to a divorce lawyer before agreeing to any support number.

Where to get free Oregon divorce help and legal resources

Oregon has solid self-help resources if you know where to look.

The Oregon Judicial Department's self-help center at courts.oregon.gov has the official dissolution forms, filing instructions, and county fee schedules ^[7]. Start there for any Oregon DIY filing.

The Oregon State Bar's Lawyer Referral Service (osbar.org) connects you to a family law attorney for a reduced-fee initial consultation, typically $35 for 30 minutes ^[5]. Worth it before you sign off on alimony terms.

Legal Aid Services of Oregon (lasoregon.org) provides free help for qualifying low-income Oregonians, including dissolution paperwork and spousal support issues ^[8].

Oregon Law Help (oregonlawhelp.org) has plain-language guides to divorce, spousal support, and property division written for non-lawyers ^[9].

For a broader look at divorce papers and what documents you actually file, that page covers the mechanics across states, Oregon included.

This article is general legal information, not legal advice for your situation. Spousal support turns on facts specific to your case, and if there's real money at stake, a one-time attorney consultation before you finalize a settlement is almost always worth the cost.

Frequently asked questions

Is there an Oregon spousal support calculator I can use online?

No official one exists. Oregon has no statutory formula for spousal support, so any online calculator is a rough estimate built on rules of thumb from other states or general patterns. Use one for ballpark thinking, but don't rely on it to negotiate a settlement. The seven factors in ORS 107.105(1)(d) are what Oregon courts actually apply, and they don't reduce to a formula.

How long do you have to be married in Oregon to get alimony?

There is no minimum marriage length in the statute. Courts can award alimony after any length of marriage if the facts justify it. In practice, marriages under five years rarely produce support unless one spouse has a serious health issue or made a documented sacrifice. Marriages over 15 years are where maintenance support becomes common. Duration is one of the seven statutory factors, not a hard cutoff.

Does Oregon have permanent alimony?

Oregon calls it "indefinite maintenance support" rather than permanent alimony, but the effect is similar. It can last until the recipient remarries, a court modifies it, or one spouse dies. Indefinite support is most common after very long marriages where one spouse cannot realistically become self-supporting. Even indefinite orders can be modified later under ORS 107.135 if circumstances change substantially.

Does cheating or adultery affect alimony in Oregon?

Oregon is a no-fault divorce state. Courts do not consider marital misconduct like adultery when dividing property or setting spousal support. ORS 107.025 allows dissolution based solely on irreconcilable differences. A spouse's affair does not raise or lower the alimony award. Economic misconduct (hiding assets, wasting marital funds) is a separate matter and can be raised in property division.

Can a husband get alimony from a wife in Oregon?

Yes. Oregon spousal support law is gender-neutral. Either spouse can receive or pay support based on the same statutory factors. The court looks at the income gap and each spouse's circumstances, not who is male or female. Male recipients are less common statistically but are routinely awarded support when the facts support it.

What happens to alimony if I remarry in Oregon?

Spousal support terminates automatically on the remarriage of the receiving spouse under Oregon law, unless the decree specifically says otherwise. You don't need to file a motion. The obligation ends by operation of law. The paying spouse should keep documentation of the new marriage in case they need to prove the termination date if a dispute comes up later.

Is Oregon alimony taxable income in 2024?

For divorces finalized after December 31, 2018, no. The Tax Cuts and Jobs Act of 2017 removed the deduction for paying spouses and the income inclusion for receiving spouses. Alimony is now tax-neutral at the federal level for modern divorces. Oregon conforms to federal treatment here. If your divorce was finalized before January 1, 2019, the old rules (deductible and taxable) still apply to that decree.

How does property division affect alimony in Oregon?

Oregon courts consider each spouse's financial resources, including property received in the settlement, when setting spousal support. If the lower-earning spouse gets a house with significant equity, a pension, or investment accounts, the court may reduce support accordingly. Structuring property and support together is common in negotiations, and what you agree to on one side directly moves the other.

Can we agree on our own alimony amount without a judge deciding?

Yes, and this is the normal path in an uncontested divorce. You and your spouse negotiate an amount, type, and duration, put it in a written settlement agreement, and file it with your dissolution paperwork. The judge reviews it for basic fairness and signs off. Courts almost always approve negotiated agreements. This gives both parties far more control than contested litigation and moves faster for less money.

How do I stop paying alimony in Oregon if my ex is living with someone?

You file a motion to modify or terminate under ORS 107.135, showing that your ex's cohabitation has reduced their financial need. Cohabitation alone doesn't automatically end support. You have to show the new partner contributes to household expenses. Gather evidence: lease agreements, bank records, social media, testimony. The court decides whether the cohabitation is a substantial change in circumstances justifying modification.

What is the difference between transitional and maintenance alimony in Oregon?

Transitional support is time-limited and meant to help a spouse re-enter the workforce, finish education, or gain job skills. Maintenance support is longer-term, covering ongoing needs when one spouse cannot become self-supporting within a defined window. Transitional is more common in shorter marriages. Maintenance is more common after long marriages with a large, persistent income gap. Courts can award both types in one case.

Do I need a lawyer to get alimony in Oregon?

No. You can request spousal support in your dissolution petition and negotiate it directly with your spouse without an attorney. Oregon's self-help forms at courts.oregon.gov support self-represented filers. That said, if the amount is significant, incomes are complex, or one spouse is self-employed, a one-time consultation with a family law attorney before finalizing numbers is almost always worth the cost.

How long does it take to get an alimony order in Oregon?

In an uncontested divorce where both spouses agree on support terms, you can have a final decree in 60 to 90 days after filing in most Oregon counties, subject to a mandatory 90-day waiting period from service of process. Contested alimony litigation typically takes six months to two years depending on complexity and court backlog. Multnomah County tends to have longer dockets than smaller counties.
