Washington Alimony / Spousal Support Calculator
Estimate alimony/spousal support in Washington. Calculate monthly payments based on income, marriage length, and Washington guidelines.
How This Calculator Works
Calculation methodology and assumptions
Washington alimony calculations consider the income difference between spouses, marriage duration, and family circumstances. Common guidelines use 30-35% of the income difference (25% if there are minor children, since child support is also paid). Duration is typically proportional to marriage length: short marriages (<10 years) get 3-5 years of support, medium (10-20 years) get 5-15 years, and long marriages (20+ years) may receive permanent/indefinite support.
Key State Information
Washington uses judicial discretion in setting alimony, considering multiple factors. Since Washington has no state income tax, alimony payments don't affect state tax liability. Note: Alimony is no longer deductible for federal taxes (post-2018 TCJA).
