About this calculator

Estimates the maximum spousal maintenance a Texas court can order: the lesser of 20% of the paying spouse's average monthly gross income or the statutory dollar cap (editable, Texas Family Code Chapter 8), plus an estimated duration tier based on the length of the marriage. This is an estimate only, not legal advice — actual awards depend on the specific court, county guideline worksheets, and judicial discretion, and a judge may deviate from the guideline for good cause.

FormulaTexas maintenance cap = min(20% × payor's average monthly gross income, statutory dollar cap). Duration tiers scale with marriage length under Family Code Ch. 8.

FAQ

What is the Texas formula for alimony/spousal support?

The lesser of 20% of the paying spouse's average monthly gross income or the statutory dollar cap, with duration set by marriage length.

What is the maximum spousal maintenance in Texas?

Texas caps court-ordered spousal maintenance at the lesser of 20% of the paying spouse's average monthly gross income or the statutory dollar cap (editable here), and duration is tied to the length of the marriage under Texas Family Code Chapter 8.

Is Texas spousal support guaranteed at this amount?

This is an estimate only, not legal advice — actual awards depend on the specific court, county guideline worksheets, and judicial discretion, and a judge may deviate from the guideline for good cause.

Does this account for taxes on alimony?

No — since 2019, alimony is not federally tax-deductible for the payor or taxable income for the recipient for divorces finalized after 2018; this estimate is a pre-tax guideline figure only.

Accuracy and limitations

  • Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
  • Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
  • This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
