Texas Alimony / Spousal Support Calculator
Generic planning model for Texas alimony scenarios using entered gross incomes and marriage length. Does not apply Texas law or predict a court order.
Estimate only — these are not official figures
This planning model does not implement state law. It applies the same heuristic in every state: 33% of the positive difference between the two entered annual gross incomes, or 25% when “Minor Children” is selected. That selection is only a model sensitivity; it does not calculate or subtract child support. The modeled duration horizon is four months per marriage year below 10 years, eight months per year from 10 through 19 years, and twelve months per year at 20 years or more. The model does not determine legal eligibility, need, ability to pay, the legally relevant income measure, taxes, assets or debts, marital standard of living, earning capacity, health, misconduct, child-support or custody interactions, deviations, the actual payer or recipient, or a court-ordered amount or duration. The Texas approach classification and official citation are context, not encoded law.
Do not rely on these amounts for budgeting or payment. For exact amounts, check the Texas Family Code, chapter 8: https://statutes.capitol.texas.gov/Docs/FA/htm/FA.8.htm; federal tax context: IRS Topic 452: https://www.irs.gov/taxtopics/tc452.

How This Calculator Works
Calculation methodology and assumptions
This planning model does not implement state law. It applies the same heuristic in every state: 33% of the positive difference between the two entered annual gross incomes, or 25% when “Minor Children” is selected. That selection is only a model sensitivity; it does not calculate or subtract child support. The modeled duration horizon is four months per marriage year below 10 years, eight months per year from 10 through 19 years, and twelve months per year at 20 years or more. The model does not determine legal eligibility, need, ability to pay, the legally relevant income measure, taxes, assets or debts, marital standard of living, earning capacity, health, misconduct, child-support or custody interactions, deviations, the actual payer or recipient, or a court-ordered amount or duration. Every result is therefore modeled or derived, not an official state-law calculation.
Key State Information
Texas is broadly classified as follows: maintenance is limited by threshold eligibility rules before amount and duration are considered. This classification is legal context only and never changes the calculator’s math. Chapter 8 first restricts court-ordered maintenance through statutory eligibility and minimum-reasonable-needs findings. It separately limits amount and duration. Gross-income difference alone does not establish eligibility, payer, amount, or term.
How to Use This Alimony Calculator
- 1
Enter scenario gross incomes
Enter annual gross incomes for a higher-earner and lower-earner scenario. These are model inputs only; the calculator does not apply Texas law’s income definition, taxes, deductions, assets, or earning-capacity findings.
- 2
Enter marriage duration
Marriage length changes only the model horizon: four months per marriage year below 10 years, eight months per year from 10 through 19 years, and twelve months per year at 20 years or more. It is not a legal duration rule.
- 3
Choose the minor-children sensitivity
Selecting minor children changes the generic rate from 33% to 25%. This is an editorial model sensitivity, not a child-support calculation or a state-law adjustment.
- 4
Review modeled results
Treat every amount and duration as a planning scenario, not eligibility advice, a state guideline result, or a prediction of a court order. Use the official state source linked on the calculator page for the controlling framework.
Example Calculation
Here is how this site’s generic planning model works; it is not a Texas alimony calculation.
With entered annual gross incomes of $120,000 and $45,000, no minor children selected, and a 12-year marriage, the model uses 33% of the positive $75,000 difference: $24,750 per year, rounded to $2,063 per month. Its disclosed horizon is 12 × 8 = 96 months.
Result: Modeled result: $24,750 per year (about $2,063 per month) and a 96-month model horizon. The calculator has not tested legal eligibility, need, ability to pay, taxes, child support, assets, or any state factors, so this is not a court-award estimate.
What Affects Your Results
Eligibility, Need, and Ability to Pay
Some states require threshold findings before amount or duration is considered. The calculator cannot make those findings and assumes no one is legally entitled or obligated.
Legally Defined Income and Resources
State law may use gross, net, adjusted, or otherwise defined income and may consider property, liabilities, benefits, earning capacity, and child-support interactions. The model uses only two entered gross-income figures.
Marriage and Household Circumstances
Official frameworks can consider duration, marital standard of living, age, health, contributions, education or training, children, and other facts. The model uses marriage length only for its disclosed horizon.
Support Form and Duration
Temporary, rehabilitative, reimbursement, durational, or other forms and their limits are state- and case-specific. The displayed model horizon does not select a legal form or predict an order.
Tips for Texas Residents
- Start with the official court or legislature source linked on this page. Eligibility, forms of support, duration, deviations, modification, and termination rules differ by state.
- Do not infer the legal payer or recipient from income rank alone. Courts may require threshold findings and consider income definitions, need, ability to pay, property, earning capacity, health, children, and other case facts.
- Do not subtract this modeled amount from a budget without separately accounting for taxes, child support, insurance, debt, and each household’s needs; the calculator includes none of them.
- For federal taxes, IRS Topic 452 distinguishes instruments executed after 2018 from pre-2019 instruments and certain later modifications. This calculator performs no federal or state tax calculation.
- A family-law attorney or qualified local legal-aid service can apply current law to facts and documents that this four-input model cannot evaluate.

Our editorial standardsFrequently Asked Questions
How is alimony calculated in Texas?
Texas Family Code, chapter 8 is the official starting point. Chapter 8 first restricts court-ordered maintenance through statutory eligibility and minimum-reasonable-needs findings. It separately limits amount and duration. Gross-income difference alone does not establish eligibility, payer, amount, or term. This planning tool does not implement the state guideline or factors. This planning model does not implement state law. It applies the same heuristic in every state: 33% of the positive difference between the two entered annual gross incomes, or 25% when “Minor Children” is selected. That selection is only a model sensitivity; it does not calculate or subtract child support. The modeled duration horizon is four months per marriage year below 10 years, eight months per year from 10 through 19 years, and twelve months per year at 20 years or more. None of its results determines a court award.
How long does alimony last in Texas?
This tool’s “duration” is only the disclosed model horizon, not a prediction of a court order. It cannot determine whether support is legally available or which statutory form, limit, exception, modification rule, or termination event applies. Check Texas Family Code, chapter 8 at https://statutes.capitol.texas.gov/Docs/FA/htm/FA.8.htm.
Is alimony tax deductible in Texas?
This calculator does not calculate federal or state tax effects. IRS Topic 452 says payments under instruments executed after 2018 generally are not deductible by the payer or included by the recipient; pre-2019 instruments generally retain the former treatment unless a later modification expressly adopts the repeal. State treatment can differ. See https://www.irs.gov/taxtopics/tc452.
