Washington Alimony Calculator: Estimate Spousal Maintenance
Wondering how much alimony you may pay or receive in a Washington divorce? Use our free Washington alimony calculator to compare one spouse’s monthly financial need with the amount the other spouse may have available to pay.
Washington law calls alimony spousal maintenance. Unlike child support, Washington maintenance is not calculated with a statewide formula. This tool gives you a starting point for budgeting and discussing possible support, not a prediction of what a judge will order.
Important: Washington does not have an official alimony formula. This calculator is a budgeting tool based on two issues Washington courts consider: financial need and ability to pay. It does not determine whether maintenance will be awarded, the amount a judge may order, or how long payments may last.
The result is not a court order or legal advice. Property division, child support, taxes, earning ability, the length of the marriage, and other facts may change the outcome. Use the estimate as a starting point and have a Washington family law attorney review your full financial picture.
Want More Than an Estimate?
Your monthly budget is only one part of a maintenance decision. A Washington family law attorney can review your income, expenses, property, earning ability and length of marriage, then explain what facts may matter most.
Beyond the Number
What Does Your Washington Alimony Estimate Mean?
Your result compares one spouse’s monthly financial shortfall with what the other spouse may have available after reasonable expenses. It can help you build a post-divorce budget, test different income scenarios and prepare questions for a lawyer.
It does not mean alimony will be awarded. Under RCW 26.09.090, a Washington court may award maintenance in an amount and for a period it considers fair after reviewing the spouses’ circumstances. There is no statewide formula, automatic percentage or fixed payment schedule.
Washington courts consider factors including:
- The financial resources of the spouse requesting maintenance, including separate and community property awarded in the divorce
- Whether that spouse can meet their needs independently
- The time needed for education or training that may help that spouse find suitable work
- The standard of living during the marriage or domestic partnership
- The length of the marriage or domestic partnership
- The requesting spouse’s age, physical and emotional condition, and financial obligations
- Whether the other spouse can meet their own needs while paying maintenance
The statute also says maintenance is decided without regard to misconduct. In other words, the court does not use maintenance to punish a spouse for causing the breakup.
Common Questions
Frequently Asked Questions About Washington Spousal Maintenance
These are common questions people ask after using a Washington alimony calculator.
Washington does not use a statewide formula to calculate alimony. Instead, a judge considers the factors in RCW 26.09.090, including the requesting spouse’s financial resources and needs, the other spouse’s ability to pay, the length and standard of living of the marriage, and the time needed for education or job training.
This calculator estimates a possible monthly amount by comparing financial need with ability to pay. That can be useful for budgeting, but it is not a formula used by Washington courts.
There is no automatic right to alimony in Washington, and the law does not set a minimum length of marriage. Either spouse or domestic partner may request maintenance.
A judge reviews whether support is fair based on the parties’ finances and the other factors required by law. A gap between incomes may matter, but income alone does not decide the issue.

Washington law does not set a fixed maintenance schedule. The payment period depends on the purpose of the award and facts such as the length of the marriage, the requesting spouse’s age and health, financial resources, and the time needed to become more self-supporting.
Some maintenance lasts while a spouse completes education or job training. Other awards may continue longer when a lengthy marriage, age, health or limited earning ability makes financial independence less realistic. The court can also award temporary maintenance while the divorce is pending.
You may hear rough rules based on a fraction of the marriage’s length, but those are not Washington statutes and do not bind a judge. For that reason, this calculator does not produce a duration estimate.
Possibly. Either spouse may ask the court for temporary maintenance while a divorce, legal separation or related family law proceeding is pending. Under RCW 26.09.060, the request must include facts supporting the amount requested.
A temporary maintenance order generally ends when the final decree is entered or the proceeding is dismissed. Any maintenance that continues after the divorce must be addressed in the final orders. The final amount and payment period may be different from the temporary award
Use monthly take-home income and reasonable monthly living expenses for each spouse. Income may include wages, self-employment earnings, bonuses, commissions, retirement income and other regular sources of money.
Expenses may include housing, utilities, food, transportation, insurance, health care, minimum debt payments and other necessary costs. Avoid mixing one-time expenses with recurring monthly costs. Washington’s Financial Declaration form can help you identify the financial information courts commonly request.
If income changes often or a spouse owns a business, a simple calculator may miss important details.
Sometimes. Washington courts generally may change future maintenance payments after a substantial change in circumstances. However, a separation agreement incorporated into the decree may expressly limit or prevent modification.
A job loss, major income change or serious change in financial need may support a request, but the result depends on the order and the facts. Filing quickly can matter because a court generally can modify only payments due after the request was filed.
Usually. Unless the spouses agreed otherwise in writing or the decree says something different, future maintenance ends when either party dies or when the receiving party remarries or registers a new domestic partnership. Review the exact terms of the maintenance order before assuming payments have ended.
For divorce or separation instruments executed after December 31, 2018, the paying spouse generally cannot deduct maintenance on a federal tax return, and the receiving spouse generally does not include it in federal taxable income. Different rules may apply to older instruments and certain later modifications. The IRS explains the current federal treatment of alimony.
Washington does not have an individual state income tax, but taxes can still affect the income and budget figures used in a maintenance discussion. Ask a tax professional how the rules apply to your agreement.
