Louisiana Alimony Calculator
Estimate spousal support (alimony) in Louisiana. Understand the types of alimony available, how courts calculate amounts, and how long payments may last. Updated for 2026.
Louisiana has a statutory cap for final periodic support: the amount shall not exceed one-third of the obligor's net income per La. C.C. art. 112(D). For interim spousal support under La. C.C. art. 113, there is no strict formula, but courts consider the needs of the claimant, the ability of the other party to pay, the standard of living during the marriage, and any interim or final child support obligation. Interim support is available regardless of fault; final periodic support requires the claimant to be free from fault.
