How to Interpret This Louisiana Estimate
This section explains why the calculator may move up or down. For the legal framework, eligibility standards, and source citations, use the dedicated Louisiana law guide.
Interim spousal support under La. Civ. Code art. 113 is designed to maintain financial stability during the divorce and generally ends 180 days after the divorce judgment unless extended for good cause. Final periodic spousal support under arts. 111 and 112 is a separate post-divorce remedy based on need, ability to pay, and freedom from fault. In Louisiana, spousal support is designed to address financial disparity between spouses after divorce. A spouse seeking final periodic support must generally prove need for support and freedom from fault before the divorce filing. The court also considers the other spouse's ability to pay and the parties' income, means, obligations, health, earning capacity, custody responsibilities, and tax consequences. Interim support has a different standard and focuses more on need, ability to pay, child support obligations, and the marital standard of living.
Conservative final periodic support estimate based on need and ability to pay: 25% of the difference between payer net income and recipient net income, capped at one-third of payer net income. The calculator uses net income for this planning estimate. Planning approach: Conservative final periodic support estimate based on need and ability to pay: 25% of the difference between payer net income and recipient net income, capped at one-third of payer net income. Louisiana does not use a mandatory income-difference formula for final periodic support. The one-third figure is a statutory cap on final periodic support, not a presumptive award. The court considers all relevant factors, including income and means, financial obligations, earning capacity, custody of children, time needed for education or training, health and age, duration of the marriage, tax consequences, and domestic-abuse circumstances. Interim spousal support follows a different standard and is not capped by the one-third final-support cap. This calculator uses a conservative need-based estimate and enforces the final-support cap.
Because Louisiana uses community property rules, property division under La. Civ. Code arts. 111-117, especially arts. 112, 113, 114, and 115 may reduce ongoing spousal support need. Louisiana requires freedom from fault for final periodic spousal support.
Marriage duration shapes both amount and length of support in Louisiana. For mid-length marriages, final support may be appropriate when one spouse lacks sufficient means and is free from fault. Courts evaluate earning capacity, health, custody obligations, and the time needed to improve self-support. Duration guidelines: Louisiana has no fixed marriage-length duration formula for final periodic support. Final periodic support may continue as long as statutory need and ability to pay are shown, subject to modification, termination, or further court order. Interim spousal support generally terminates 180 days after the divorce judgment unless extended for good cause. Final periodic support generally terminates upon the death of either party, remarriage of the recipient, or a judicial determination that support is no longer required, and may be affected by cohabitation or changed circumstances.
La. Civ. Code art. 111 authorizes interim periodic support and final periodic support. La. Civ. Code art. 112 governs final periodic support for a spouse in need who is free from fault.

Final support is available only to a spouse who is in need and free from fault before the filing of the divorce proceeding. Courts evaluate need, ability to pay, and statutory factors rather than using a mandatory formula.
Income and earning capacity: Louisiana courts evaluate the income and means of each spouse, including the liquidity of those means. The calculator reflects income disparity through this planning approach: Conservative final periodic support estimate based on need and ability to pay: 25% of the difference between payer net income and recipient net income, capped at one-third of payer net income.
