Alimony Calculator Alabama 2026
Alabama has no formula for the amount of alimony. This page applies the state's rule on how long it can last and shows a clearly labelled illustration of the amount from both incomes. Everything runs privately in your browser, with no sign-up.
Not legal advice — a court decides. Alabama has no formula for the amount of alimony; a judge decides it, within the statutory time limits shown.
Alabama Alimony Formula & Factors
Alabama has no formula for the amount of alimony, but it limits how long alimony can last. Under Ala. Code § 30-2-57 the court awards rehabilitative or periodic alimony only if it finds that one spouse lacks a separate estate sufficient to preserve, as far as possible, the economic status quo of the marriage, that the other spouse can supply those means without undue economic hardship, and that the circumstances make an award equitable.
In deciding whether an award is equitable the court weighs the length of the marriage, the standard of living, relative fault for the breakdown, the age and health of the spouses, future employment prospects, and each spouse's contributions and sacrifices for the other or the family.
What This Alimony Calculator Alabama Tool Estimates
Because Alabama law gives no figure to calculate, the dollar amount on this page is an illustration only. It uses the reference method recommended by a commission of the American Academy of Matrimonial Lawyers (AAML) and adopted by its Board of Governors in March 2007: 30% of the payor's gross income minus 20% of the recipient's gross income, limited so that the recipient ends up with no more than 40% of the couple's combined gross income. The method is set out in Mary Kay Kisthardt's article in the Journal of the American Academy of Matrimonial Lawyers (vol. 21, 2008) and summarised by Maryland's highest court in Boemio v. Boemio (2010).
The AAML method is not Alabama law and Alabama courts are not bound by it. It lists its own reasons to depart from the result, such as a spouse caring for a young or disabled child, age or health, or a career given up for the other spouse. It was written when alimony was still tax-deductible for the payer, and it does not apply when combined gross income is above $1,000,000 a year. Treat the figure as a starting point for a conversation with a lawyer, not as a prediction.

Worked Example: Alimony Calculator Alabama
Take gross incomes of $8,000 and $3,000 a month. Under the AAML reference method, 30% of $8,000 is $2,400 and 20% of $3,000 is $600, a difference of $1,800. The limit is 40% of the combined $11,000, which is $4,400, less the recipient's own $3,000: $1,400. The illustrative amount is the lower figure, $1,400 a month ($16,800 a year). This is an illustration, not an amount set by Alabama law.
For a 12-year marriage, the Alabama rule on length gives up to 12 years.
These are the figures the calculator shows when the page first loads. A real order depends on evidence a calculator cannot see.
Alabama Alimony Duration Rules
Rehabilitative alimony comes first and is limited to five years unless there are extraordinary circumstances. Periodic alimony is available when rehabilitation is not feasible or has not fully worked. A spouse is eligible for periodic alimony for no longer than the length of the marriage, measured to the filing of the complaint, unless the court finds that a deviation is equitably required. If the marriage lasted 20 years or longer there is no time limit.
An award can be modified on a showing of a material change in circumstances, and it ends on the death of either spouse or as provided in section 30-2-55.
Is Alimony Taxable in Alabama?
For federal income tax, alimony or separate maintenance paid under a divorce or separation agreement executed after 2018 is not deductible by the payer and is not included in the recipient's income. Payments under an agreement executed before 2019 are generally still deductible by the payer and taxable to the recipient, unless the agreement was later modified and the modification expressly adopts the new rule (IRS Topic No. 452). Child support is never deductible and is not income.
This page does not cover Alabama state income tax. State rules are set separately and can differ from the federal rule, so check with the state tax agency or a tax adviser.
Modifying Alabama Alimony
Whether an order can be changed depends on its wording and on the type of support. In most cases either spouse can ask the court to modify periodic payments after a substantial change in circumstances, unless the decree or the spouses' agreement makes the support non-modifiable.
Read the order itself and Ala. Code § 30-2-57 before relying on a general rule, and get advice from a family lawyer licensed in Alabama about your own case. Nothing on this page is legal advice.

Frequently Asked Questions
How is alimony calculated in Alabama?
Alabama has no formula for the amount. Under Ala. Code § 30-2-57 the court awards alimony only if one spouse lacks the means to preserve the economic status quo of the marriage, the other can pay without undue hardship, and an award is equitable. The amount on this page is an illustration using the AAML reference method, not Alabama law.
Does Alabama use a formula for alimony?
No. Ala. Code § 30-2-57 sets no percentage for the amount. It does set time limits: rehabilitative alimony for up to five years, and periodic alimony for no longer than the length of the marriage unless the marriage lasted 20 years or more.
How long does Alabama alimony last?
Rehabilitative alimony is limited to five years unless there are extraordinary circumstances. Periodic alimony may last no longer than the marriage did, so up to 12 years after a 12-year marriage, unless the court finds a deviation is equitably required. After a marriage of 20 years or more there is no time limit (Ala. Code § 30-2-57).
Can Alabama alimony be modified?
It depends on the order. In most cases either spouse can ask the court to modify periodic payments after a substantial change in circumstances, unless the decree or the spouses' agreement makes the support non-modifiable. Check the wording of your order and Ala. Code § 30-2-57 before relying on a general rule.
Is alimony taxable in Alabama?
For federal income tax, alimony paid under a divorce or separation agreement executed after 2018 is not deductible by the payer and is not income to the recipient (IRS Topic No. 452). Agreements executed before 2019 generally keep the old treatment, deductible by the payer and taxable to the recipient, unless a later modification expressly adopts the new rule. This page does not cover Alabama state income tax, which is set separately.
Is this Alabama alimony calculator free and private?
Yes. It is free, needs no sign-up, and the calculation runs in your browser, so the incomes you type are not uploaded by the calculator.
How do I use this alimony calculator Alabama tool step by step?
Enter each spouse's monthly gross income and the length of the marriage in years, then press Calculate. The result shows the monthly and yearly figure, what kind of figure it is, and how long support could last under Alabama law or, where the law is silent, under the reference method. Change any number and press Calculate again to compare.
Why does the alimony calculator Alabama estimate not match what the judge orders?
Because Alabama has no formula for the amount. A judge weighs the factors in Ala. Code § 30-2-57 on the evidence in each case, and the figure here is only an illustration using the AAML reference method. Two couples with the same incomes can receive different orders.
Does adultery affect Alabama alimony?
It can. The relative fault of the spouses for the breakdown of the marriage is one of the factors the court must consider in deciding whether an alimony award is equitable (Ala. Code § 30-2-57(f)(3)).
Does this alimony calculator Alabama result include child support?
No. The figure is spousal support only. Child support is worked out separately under Alabama's child support guidelines.
