Louisiana Alimony Calculator 2026

There is no Louisiana alimony formula to run. A judge weighs nine Civil Code factors, and final support can never top one-third of the payer’s net income. This page shows the factors and the few hard rules instead of inventing a number.

What Louisiana courts weigh instead of a formula

LA sets alimony by judicial discretion; there is no statutory formula. Courts weigh the enumerated factors below.

Factors the court weighs

The income and means of the parties, including the liquidity of such means
The financial obligations of the parties, including any interim allowance or final child support obligation
The earning capacity of the parties
The effect of custody of children upon a party’s earning capacity
The time necessary for the claimant to acquire appropriate education, training, or employment
The health and age of the parties
The duration of the marriage
The tax consequences to either or both parties
The existence, effect, and duration of any act of domestic abuse committed by the other spouse upon the claimant or a child of one of the spouses, regardless of whether the other spouse was prosecuted for the act of domestic violence

La. Civ. Code art. 112(C) (nine enumerated factors)

Assumptions

This tool does not estimate a dollar amount for discretionary states: any number would be invented.
Final periodic support is capped at one-third of the obligor’s NET income (art. 112(D)); the cap may be exceeded, and a lump sum awarded, in the domestic-abuse and fault-based divorce cases the article lists. Entitlement requires the claimant to be free from fault before the divorce filing (art. 112(A)), with a presumption of entitlement for abuse victims (art. 112(C)). Interim spousal support under art. 113 is a separate discretionary award while the case is pending; it terminates 180 days after the divorce judgment absent good cause.

Estimate only. The court or state agency calculation controls.

Louisiana alimony under La. Civ. Code art. 112 (final periodic support); La. Civ. Code art. 113 (interim spousal support).

How Louisiana decides spousal support without a formula

Louisiana splits spousal support into two civil-law remedies. Interim spousal support under Civil Code article 113 keeps the household running while the divorce is pending, based on the claimant’s needs, the other spouse’s ability to pay, any child support obligation in play, and the standard of living during the marriage. It ends 180 days after the divorce judgment unless the court finds good cause to extend it.

Final periodic support under article 112 is the long-term award, and it has a gate: the claimant must need support and must be free from fault in the breakup before the petition for divorce was filed. A spouse who was the victim of domestic abuse during the marriage is presumed entitled to it.

Once through the gate, the judge weighs nine listed factors: the income and means of each side including how liquid those means are, existing financial obligations including child support, earning capacity, the effect of child custody on earning capacity, the time the claimant needs for education or training, health and age, the length of the marriage, tax consequences, and the existence and effect of domestic abuse.

The one hard number in the article is a ceiling, not a formula. Article 112(D) caps final periodic support at one-third of the obligor’s net income. The cap can be exceeded, and even converted to a lump sum, in the domestic-abuse divorce situations the article lists, but it never turns into a computation that produces the award itself.

Everything else is discretion. Nothing in the Civil Code multiplies incomes, sets duration bands, or scores the marriage, which is why any Louisiana alimony calculator that prints a monthly figure is guessing at something the law leaves to the judge.

How to use this page

Use the panel above as a preparation checklist rather than a calculator. It lists the nine factors a Louisiana judge must weigh, so you can pull evidence for each one that touches your marriage: income records and how reachable the money actually is, obligations, health, the custody arrangement, and what retraining would take.

The one number worth computing yourself is the ceiling. One-third of the paying spouse’s net income is the most a final periodic award can be outside the abuse exceptions, so it frames every negotiation even though it decides nothing by itself.

Keep the two remedies straight. Interim support runs on need and lifestyle while the case is pending and dies 180 days after the judgment; final periodic support needs the freedom-from-fault showing and the factor weighing. Numbers discussed for one do not carry over to the other.

Be wary of any site that prints a Louisiana alimony estimate. With no formula in the Civil Code, such numbers are imported from other states’ rules or invented, and a Louisiana judge is bound by neither.

Louisiana spousal support FAQs

How is alimony calculated in Louisiana?

It is not calculated; it is weighed. Article 112 directs the judge through nine factors, from income and earning capacity to the duration of the marriage and domestic abuse, and then bounds the result: final periodic support cannot exceed one-third of the obligor’s net income. No percentage or chart in the Civil Code produces the award.

What is the difference between interim and final spousal support?

Timing and test. Interim support under article 113 runs while the divorce is pending, based on need, ability to pay, any child support obligation, and the marital standard of living; it ends 180 days after the divorce judgment absent good cause. Final periodic support under article 112 is the post-divorce award, which requires freedom from fault and the nine-factor weighing.

Does fault matter for Louisiana spousal support?

Decisively, for the final award. A spouse seeking final periodic support must be free from fault before the divorce petition was filed; serious misconduct that contributed to the breakup can bar the claim entirely. The code also presumes entitlement for a spouse who was the victim of domestic abuse during the marriage.

Is there really a one-third cap?

Yes. Article 112(D) says the final periodic award shall not exceed one-third of the obligor’s net income. The same subsection lets courts exceed the cap, and award a lump sum, in the listed domestic-abuse divorce situations. Note the base is net income, unlike the child support guidelines, which run on gross.

How long does Louisiana spousal support last?

As long as the judgment says. The Civil Code publishes no duration schedule tied to marriage length; duration comes out of the same discretionary weighing as amount. Final periodic support also ends by law on remarriage of the receiving spouse, and interim support has its built-in 180-day sunset after the divorce.

Why does this site show calculators for some states but only factors here?

Because the honest answer differs by state. Texas has a statutory ceiling formula and New York a published equation, so those pages compute. Louisiana publishes factors plus a ceiling, so this page renders the factors and the ceiling. Running invented math would misstate the law we cite.

Good to know in Louisiana

Louisiana court papers say spousal support, not alimony; older cases used alimony pendente lite for what article 113 now calls interim spousal support.
Louisiana is a community property state, so the property partition happens in its own proceeding and can change what support is realistic; the factor list looks at the means each spouse ends up with.
