Estimate spousal support under state formulas — Illinois, New York, Texas, Massachusetts, and Colorado have statutory guidelines; other states are estimated from common court outcomes.
Unlike child support, most states have no binding alimony formula — judges weigh statutory factors like marriage length, earning capacity, and standard of living. But a meaningful minority use real formulas: Illinois (33.3% of payor's net income minus 25% of recipient's, capped at 40% of combined), New York (a dual formula with a $241,000 payor income cap from March 2026), Texas (capped at the lesser of $5,000/month or 20% of gross), Massachusetts (30-35% of the income difference), and Colorado (an advisory 40%-of-combined formula).
For formula states this tool implements the statute directly, including duration multipliers where they exist (Illinois's marriage-length table, Massachusetts's percentage brackets). For discretionary states we show a reference range based on income difference — clearly labeled as such.
There is no universal minimum, but duration matters everywhere. Texas requires 10+ years for most maintenance awards. Massachusetts caps duration at 50% of marriage length for marriages under 5 years, rising to indefinite alimony after 20 years.
For divorces finalized after 2018, alimony is not deductible by the payor and not taxable income to the recipient under federal law. Some states differ for state income tax.
In formula states, yes. New York uses a lower percentage formula when the payor also pays child support; Illinois calculates maintenance first, which then changes net income for child support.
Usually yes, on a substantial change in circumstances — job loss, retirement, remarriage or cohabitation of the recipient. Some agreements make alimony non-modifiable by contract.
