California Alimony Calculator
Estimated temporary support = 40% of payer gross monthly income minus 50% of recipient gross monthly income (common Santa Clara-style guideline approximation).
California refers to ongoing payments between former spouses as spousal support. Temporary support during a divorce is often guided by local court formulas, while long-term support after judgment is based on the statutory factors in Family Code § 4320. Courts focus on need, ability to pay, marital standard of living, and the goal of reasonable self-support.
Calculate for CA →Florida Alimony Calculator
35% of payer income − 25% of recipient income (need-based educational estimate under § 61.08)
Florida awards alimony based on the receiving spouse's need and the paying spouse's ability to pay. Following major statutory reforms, Florida eliminated permanent alimony and now relies primarily on bridge-the-gap, rehabilitative, and durational forms of support. Courts must evaluate statutory factors before determining amount and duration.
Calculate for FL →Georgia Alimony Calculator
Educational estimate based on income disparity, demonstrated need, ability to pay, marriage length, and Georgia statutory factors.
Georgia awards alimony based on the needs of one spouse and the other spouse's ability to pay, with courts exercising substantial discretion. The state does not use a mandatory mathematical formula for determining alimony. Instead, judges evaluate statutory factors and the overall equities of the marriage and divorce.
Calculate for GA →New York Alimony Calculator
30% of payer income − 20% of recipient income within the statutory income cap (DRL § 236(B) presumptive maintenance)
New York uses the term maintenance for spousal support and employs statutory formulas that provide presumptive maintenance amounts in many cases. Courts begin with the statutory calculation but may deviate when the formula would be unjust or inappropriate after considering statutory factors. Maintenance awards are intended to address economic disparities created by the marriage and divorce.
Calculate for NY →Ohio Alimony Calculator
Educational estimate based on Ohio spousal support worksheets, income disparity, marriage length, and statutory factors under Ohio Revised Code § 3105.18.
Ohio refers to post-divorce payments as spousal support and does not impose a mandatory statewide formula for final awards. Courts determine whether support is appropriate and reasonable by applying the factors listed in Ohio Revised Code § 3105.18. While some counties use worksheets or local guidelines for settlement discussions, final decisions remain discretionary.
Calculate for OH →Texas Alimony Calculator
Estimated maximum maintenance = lesser of $5,000 per month or 20% of payer gross monthly income, subject to statutory eligibility requirements.
Texas uses the term spousal maintenance for court-ordered post-divorce support and imposes some of the nation's strictest eligibility requirements. Unlike many states, support is not presumed based solely on income disparity, and a spouse must first satisfy statutory eligibility thresholds before a court considers amount and duration.

How accurate is this alimony calculator?+
This tool provides educational estimates based on simplified formulas and general guidelines. Actual court awards depend on state law, judge discretion, and case-specific evidence. Always consult a family law attorney.

Formulas vary by state. California uses a 40%/50% gross-income guideline for estimates; Texas caps maintenance at $5,000/month or 20% of payer income; Illinois uses 33.33% payer net minus 25% recipient net; New York and Florida use their own guideline structures. Select your state in the calculator for the matching formula.
Does alimony vary by state?+
Yes — significantly. Each state page uses a different simplified formula, duration rules, and eligibility notes based on local spousal support law. California, Texas, Florida, New York, and Illinois each produce different estimates from the same inputs.
Is this legal advice?+
No. SettleCompass is an educational resource only. We are not a law firm and do not provide legal advice. Use these estimates for planning and research, not as a substitute for professional counsel.
How long does alimony typically last?+
Duration depends on marriage length and state law. Short marriages (under 5 years) often see 1–3 years of support. Marriages of 10–20 years may see 5–10 years. Marriages over 20 years may result in long-term support.
