Texas Alimony & Spousal
Support Calculator

Texas uses a statutory formula to calculate spousal maintenance, providing a more predictable framework for divorcing spouses than pure judicial discretion. Under Tex.

Fam. Code § 8.051, the court applies a mathematical formula based on each spouse's gross income to determine both the amount and duration of alimony payments.

While the formula provides a presumptive guideline, Texas courts retain the ability to deviate from it when circumstances warrant.

The formula-based approach in Texas was designed to reduce divorce litigation costs and increase consistency across family law cases. The state's formula considers limited to lesser of $5,000/month or 20% of obligor's gross income; marriage must be 10+ years; duration capped at 5-10 years depending on marriage length.

However, the formula is just a starting point — judges may adjust the final spousal maintenance award based on the specific facts of each case, including the standard of living during the marriage, the age and health of both parties, and the distribution of marital property.

Use our Texas alimony calculator above to estimate your spousal maintenance obligation or entitlement based on the formula. Whether you are the paying spouse or the receiving spouse, the formula output gives you a realistic range to negotiate from before engaging with an attorney.

Family law attorneys in Houston and across Texas can explain how local courts apply the formula in practice and whether your facts support a deviation.

Texas recognizes several types of spousal maintenance: temporary (spousal support), contractual, court-ordered maintenance. Each serves a different purpose and applies under different divorce circumstances.

The type of alimony awarded depends on the length of the marriage, the financial circumstances of both spouses, and the specific needs demonstrated by the requesting party.

Temporary alimony (also called pendente lite spousal maintenance) is awarded during the divorce proceedings to maintain the financial status quo while the case is pending. This type of support ensures that the lower-earning spouse can cover living expenses — including housing, utilities, and basic needs — until Texas courts issue a final spousal maintenance order.

Temporary support automatically terminates when the final divorce decree is entered.

Texas distinguishes between contractual spousal maintenance (agreed upon by the spouses in a divorce settlement) and court-ordered spousal maintenance. Contractual alimony is governed by the terms of the divorce agreement and is generally non-modifiable unless the agreement itself provides for modification.

Court-ordered spousal maintenance is subject to modification based on a material change in circumstances.

Texas uses a statutory formula to determine presumptive spousal maintenance amounts based on each spouse's gross income. The formula works as follows: limited to lesser of $5,000/month or 20% of obligor's gross income; marriage must be 10+ years; duration capped at 5-10 years depending on marriage length.

This mathematical approach provides a starting point that both parties and their family law attorneys can use to estimate likely alimony obligations before going to court. For example, if the higher earner brings home $8,000/month and the lower earner makes $3,000/month, the formula produces a specific presumptive figure that the court can then adjust based on the circumstances of the case.

The formula calculates a presumptive amount, but Texas courts are not strictly bound by it. Judges may deviate from the formula result if the presumptive amount would be unjust or inappropriate given the specific circumstances of the divorce.

Common reasons for deviation include significant disparity in assets, one spouse's contribution as a homemaker, family violence, or the tax consequences of the spousal maintenance award.

Duration of alimony is also guided by statutory formulas in Texas, typically based on a percentage of the length of the marriage. For shorter marriages, spousal maintenance duration in many jurisdictions runs **15–30%** of the marriage length as a general benchmark — though Texas courts retain discretion to deviate based on the specific circumstances of each case.

For marriages exceeding 20 years, courts may award indefinite alimony. Use our Texas alimony calculator to estimate both the amount and duration based on your specific monthly gross income figures and marriage length.

Texas family law limits spousal maintenance using the "minimum reasonable needs" standard under Tex. Fam.

Code § 8.051. Unlike many states where alimony is based on maintaining the marital standard of living, Texas courts only award spousal maintenance sufficient to meet the requesting spouse's minimum reasonable needs.

This makes Texas one of the most restrictive states for alimony eligibility.

To qualify for court-ordered spousal maintenance in Texas, the requesting spouse must demonstrate that they lack sufficient property and earning capacity to provide for their minimum reasonable needs. At least one of these conditions must also apply: the marriage lasted 10+ years and the spouse cannot earn sufficient income, a spouse has been convicted of or received deferred adjudication for family violence within two years of the divorce filing, the requesting spouse has an incapacitating physical or mental disability, or a child of the marriage requires substantial care due to a disability.

Texas law also caps the monthly amount at the lesser of $5,000 or 20% of the paying spouse's average monthly gross income.

The length of the marriage is the single most important factor in determining how long alimony lasts in Texas. Short-term marriages (generally under 10 years) rarely result in long-term alimony awards.

When spousal maintenance is granted for a short marriage, it is typically rehabilitative and limited to 2–5 years — enough time for the receiving spouse to become self-supporting through education or training.

For moderate-length marriages (10–20 years), spousal maintenance duration in Texas is often set as a percentage of the marriage length. As a general benchmark used by many courts, that figure falls in the range of **30–50%** of the marriage — though Texas judges have discretion to award more or less based on the specific facts.

A 15-year marriage, for example, might result in a alimony award lasting 5–7 years. The specific duration depends on factors like the age of the receiving spouse, their earning capacity, and whether they sacrificed career opportunities during the marriage.

Long-term marriages (20+ years) may qualify for indefinite or permanent spousal maintenance in Texas, particularly when the receiving spouse is older, has limited earning capacity, or made significant career sacrifices to support the family. Even permanent alimony is subject to review and modification if circumstances change substantially — for example, if the paying spouse retires or the receiving spouse begins cohabiting with a new partner.

Under the Tax Cuts and Jobs Act (TCJA) of 2017, alimony payments pursuant to divorce agreements executed after December 31, 2018 are no longer tax-deductible for the paying spouse or taxable income for the receiving spouse. This was a major change from prior law, where the payor could deduct spousal maintenance payments and the recipient reported them as gross income.

If your divorce was finalized before 2019 and you have not modified the agreement, the old tax rules may still apply to your payments. See IRS Publication 504 (Divorced or Separated Individuals) for the federal tax treatment that applies regardless of state.

Spousal maintenance orders in Texas can be modified if either spouse demonstrates a material change in circumstances. Common grounds for modification include significant changes in income (job loss, disability, retirement, or substantial raise), changes in the receiving spouse's financial needs, or the receiving spouse becoming self-supporting sooner than expected.

The party seeking modification bears the burden of proving the changed circumstances to Texas courts.

Spousal maintenance in Texas typically terminates automatically upon the remarriage of the receiving spouse or the death of either party. Texas also allows termination or reduction of alimony if the receiving spouse enters into a supportive cohabitation arrangement — essentially living with a new partner in a marriage-like relationship.

In Texas, child support and alimony are calculated separately but interact with each other. Most Texas courts calculate child support first using the state's child support guidelines — use the Texas Child Support Estimator to see how that figure is determined — then determine spousal maintenance based on the remaining gross income available to each spouse.

This sequencing matters because child support obligations reduce the paying spouse's available income for alimony purposes. Some states impose a combined cap, limiting total support payments (child support plus spousal maintenance) to a percentage of the payor's gross income, often **40–50%**.

Unlike child support, which follows formulaic guidelines tied to income changes, alimony modification generally requires a more substantial showing of changed circumstances. Child support generally takes priority in Texas — if the paying spouse's income drops, courts typically preserve child support obligations before adjusting spousal maintenance obligations.

Child support also ends when the child reaches the age of majority, which may trigger a review of alimony if the paying spouse's financial picture changes significantly during the divorce process.

Alimony is one component of the overall divorce financial picture. The Texas Divorce Cost Estimator projects total attorney fees and filing costs for your case.

For divorces with children, the Texas Child Support Estimator calculates guideline support amounts using Texas's income model. And for marital property allocation, the Texas Property Division Calculator covers Texas's equitable distribution or community property rules.
