Formula and Logic
This calculator uses a simplified model based on common spousal support guidelines followed in many U.S. jurisdictions. It is not a substitute for legal advice.
Core calculation steps:
- Base duration: 50% of marriage length for marriages under 10 years, up to 100% of marriage length (capped at 10 years) for marriages 10+ years.
- Support type adjustment: Temporary support capped at 2 years, rehabilitative at 5 years, permanent support follows base duration rules.
- Disability adjustment: +2 years added if the payee has a work-limiting disability.
- Dependent child adjustment: +1 year per child (max 3 years total).
- Income ratio adjustment: +1 year if payee income is less than 50% of payor income.
- Jurisdiction-specific caps: Adjustments applied for California, Texas, New York, Florida, and other states per local guidelines.
Practical Notes
Spousal support rules vary significantly by jurisdiction. Keep these legal-specific considerations in mind:
- All calculations are estimates only. Court-ordered support duration depends on judicial discretion and case-specific evidence.
- Many jurisdictions consider additional factors not included here, such as marital misconduct, separate property, and retirement plans.
- For marriages lasting 10+ years in California, courts may order indefinite support rather than a fixed term.
- Texas has strict caps on spousal support duration (max 5 years) regardless of marriage length for most cases.
- Always consult a qualified family law attorney in your jurisdiction to get advice tailored to your case.

Frequently Asked Questions
Is this spousal support duration estimate legally binding?
No. This tool uses generalized guidelines and is not recognized by any court. All spousal support orders must be issued by a judge or approved in a signed marital settlement agreement.
Can I use this tool for jurisdictions outside the United States?
No. This calculator is designed for U.S. state jurisdictions only. Spousal support (alimony) rules in other countries, provinces, or territories follow entirely different legal frameworks.
What if my marriage was a same-sex marriage?
The calculation factors apply equally to all legal marriages, including same-sex marriages, as long as the marriage was legally recognized in your jurisdiction.
Additional Guidance
Spousal support laws change frequently. Check your state’s most recent family code or equivalent legislation before relying on any estimate.
If you are low-income, many jurisdictions offer free or sliding-scale family law legal aid services to help with support negotiations.
Keep detailed records of all income, assets, and marriage-related expenses to present as evidence if your case goes to court.
