Michigan Alimony Calculator 2026
Michigan law gives judges a standard, just and reasonable, instead of a formula. Any site that prints a Michigan alimony number is running unofficial math. This page shows what actually decides the award.

What Michigan courts weigh instead of a formula
MI sets alimony by judicial discretion; there is no statutory formula. Courts weigh the enumerated factors below.
Factors the court weighs
- Past relations and conduct of the parties
- Length of the marriage
- Ability of the parties to work
- Source and amount of property awarded to the parties
- Age of the parties
- Ability of the parties to pay support
- Present situation of the parties
- Needs of the parties
- Health of the parties
- Prior standard of living of the parties
- General principles of equity
MCL 552.23(1) statutory standard; factor list developed by Michigan case law (not statutory)
Assumptions
- This tool does not estimate a dollar amount for discretionary states: any number would be invented.
- No statutory guideline amounts or duration formula; any "Michigan alimony formula" found online is unofficial. Termination-on-remarriage terms per MCL 552.13.
- MCL 552.23 (spousal support; discretionary, no formula)
- MCL 552.13 (alimony in divorce and separate maintenance actions; termination on remarriage terms)
Estimate only. The court or state agency calculation controls.
Michigan alimony under MCL 552.23(1) (spousal support); MCL 552.13 (alimony; termination terms).
How Michigan decides spousal support without a formula
The controlling statute is MCL 552.23(1). It lets a court award spousal support "as the court considers just and reasonable" after looking at each party ability to pay and the character and situation of the parties, and all the other circumstances of the case. That sentence is the whole statutory test: no percentages, no income caps, no duration chart.
The working factor list comes from Michigan appellate decisions rather than the statute. Courts weigh the past relations and conduct of the parties, the length of the marriage, each party ability to work, the property each received, their ages, ability to pay, present situation, needs, health, the prior standard of living, and general principles of equity.
Some attorneys and software vendors circulate prediction formulas for settlement talks. None of them are law. A Michigan judge is free to ignore any such output entirely, which is why this page renders the factors instead of a number.
Older language still matters at the edges. MCL 552.13 carries the historical alimony provision, including the court power to make support terms end when the recipient remarries. Modern orders spell out their own modification and termination terms.

How to use this page
Treat the panel above as an evidence checklist. Each factor a Michigan judge weighs is something you can document: earnings history, health records, the property division, the standard of living during the marriage, and what each spouse can realistically earn now.
Be careful with any Michigan alimony calculator that outputs dollars and months. Those tools encode someone’s settlement heuristic, not Michigan law, and opposing counsel is not bound by them any more than the judge is.
Spousal support in Michigan is decided alongside the property division, and the two trade off. The source and amount of property awarded to each party is itself one of the factors, so the support question rarely stands alone.
Child support is different: that side of a Michigan case does have binding math. Our Michigan child support page runs the 2025 formula if children are involved.
What this estimate includes
- The MCL 552.23(1) statutory standard, quoted plainly
- The case-law factor list Michigan courts actually recite
- The MCL 552.13 remarriage-termination rule
- Links to the official statutes on the Michigan Legislature site
What it leaves out
- Any dollar estimate of a Michigan spousal support award
- Any duration prediction, because no schedule exists
- Property division itself, which is a separate equitable question
- Child support, which has its own formula and its own page here
Michigan spousal support FAQs
How is spousal support calculated in Michigan?
It is not calculated; it is weighed. MCL 552.23(1) directs the court to award what is just and reasonable after considering ability to pay and the circumstances of the case, and Michigan case law supplies the familiar factor list: conduct, length of the marriage, ability to work, property awarded, age, health, needs, prior standard of living, and equity. No statute converts those factors into dollars.
Is there any official Michigan alimony formula at all?
No. The prognosticator-style formulas some family lawyers use are private settlement tools with no legal force. The contrast with child support is sharp: MCL 552.605 binds courts to the child support formula manual, while spousal support has no equivalent manual to bind anyone.
How long does Michigan spousal support last?
As long as the order says, and the statute publishes no schedule tying years of support to years of marriage. Duration comes out of the same discretionary weighing as the amount. Periodic spousal support is generally modifiable on changed circumstances unless the parties agreed otherwise in a binding way.
Does remarriage end Michigan spousal support?
Often, but read the order. MCL 552.13 permits courts to terminate support when the recipient remarries, and many judgments build that term in expressly. Whether a particular award survives remarriage depends on the judgment language and the kind of support ordered.
Does misconduct change the award?
It can, as one factor among many. The past relations and conduct of the parties is the first factor Michigan courts recite, but Michigan has no rule that adultery mandates or bars an award the way some states do. Conduct gets weighed, not scored.
Why does this site calculate child support for Michigan but not alimony?
Because Michigan publishes binding math for one and not the other. The 2025 child support formula manual is law under MCL 552.605, so a calculator can run it faithfully. Spousal support has only a discretionary standard, so an honest page shows the factors and refuses to print a made-up number.
Good to know in Michigan
- Michigan statutes use the term spousal support; alimony is the older word and still appears in MCL 552.13. Court forms and the Friend of the Court use spousal support.
- Spousal support paid between the parents of the children in a case is not deducted from the payer income in the child support formula, a detail that surprises people running both numbers.
- The Friend of the Court can collect and enforce spousal support through the same income withholding machinery it uses for child support when the order provides for it.
