Michigan has no statutory alimony formula
Michigan has no statutory alimony formula, so this figure uses the AAML national guideline (30% of the payor's gross income minus 20% of the payee's, capped at 40% of combined income) purely as a ballpark. The figure below is an estimate to give you a ballpark — a Michigan judge decides the actual amount and duration using the factors listed beneath the calculator. About this method.

Eligibility: No minimum marriage length; either party may be awarded support. Support is awarded only where the estate and effects of the parties are insufficient for suitable support and maintenance.
Factors Michigan Courts Weigh
- •Past relations and conduct of the parties, including marital fault
- •Length of the marriage
- •Each party's ability to work and earning capacity
- •Source and amount of property awarded to each party in the divorce
- •Age of the parties
- •Ability of the paying party to pay spousal support
- •Present situation and needs of each party
- •Health of the parties
- •Prior standard of living during the marriage and whether either party supports others
- •Contributions of each party to the joint marital estate
- •Effect of cohabitation on a party's financial status
- •General principles of equity
How Michigan Alimony Works
- •Michigan has NO statutory formula for the amount or duration of spousal support. Under MCL 552.23 the court awards support 'as the court considers just and reasonable' based on the parties' ability to pay, character and situation, and all circumstances of the case.
- •The governing factors come from case law, principally Sparks v. Sparks, 440 Mich. 141 (1992), which a court must consider and weigh; no single factor is dispositive and courts must make specific findings.
- •Practitioners and some local courts use an informal benchmark of roughly 30-40% of the income gap between spouses as a starting estimate, but this is NOT a binding statute or court rule and judges are free to depart from it.
- •Spousal support in Michigan can be modifiable (periodic) or non-modifiable (in gross / lump sum); modifiable support generally ends on remarriage or death unless otherwise ordered.
- •The 2017-2018 federal Tax Cuts and Jobs Act changes (post-2018 awards are not federally tax-deductible to the payor or taxable to the payee) affect Michigan awards; no recent Michigan statutory alimony reform has replaced the discretionary Sparks framework as of June 2026.
This is an estimate for educational purposes only, not legal advice. Alimony is highly discretionary; a Michigan judge can order a different amount or duration. Consult a licensed Michigan family-law attorney about your situation. See the official Michigan resource.
How Michigan Calculates Alimony
Michigan addresses spousal support under MCL 552.23. It uses a guideline equation that takes a percentage of the payor's gross income and subtracts a percentage of the payee's gross income, with statutory caps. The calculator above applies that equation to your figures and shows each step.
Unlike child support, alimony is one of the most discretionary areas of family law. Even in states with a guideline equation, the figure is a starting point a judge can adjust after weighing the statutory factors, the length of the marriage, and each spouse's needs and ability to pay. Treat any number here as an informed estimate, not a guaranteed award.
Key Rules in Michigan

How Long Alimony Lasts in Michigan
Under the AAML national guideline, duration is a share of the marriage length that rises with the length of the marriage; marriages of 20+ years may receive indefinite support. This is an illustration, not a state durational rule.
What Counts as Income
Michigan's calculation uses each spouse’s gross income — earnings before taxes, including wages, bonuses, commissions, self-employment income, and many recurring sources. Courts can also impute income to a spouse who is voluntarily unemployed or underemployed, meaning support can be based on what a spouse could earn rather than what they currently do. Use your most recent pay stubs and tax return for the most accurate estimate.
Eligibility & Modifying an Order
No minimum marriage length; either party may be awarded support. Support is awarded only where the estate and effects of the parties are insufficient for suitable support and maintenance.
Alimony orders can usually be modified when there is a substantial change in circumstances — for example, a significant change in either spouse's income, the recipient's remarriage or cohabitation, retirement, or the payor's loss of employment. The specific rules and any non-modifiable agreements depend on your court order and Michigan law.
Frequently Asked Questions
Is this Michigan alimony calculator accurate?
It applies the Michigan guideline from MCL 552.23 to the numbers you enter, so it gives a close estimate of a typical guideline award. It is not an official court calculation — a judge can order a different amount after weighing the statutory factors.
Is alimony taxable in Michigan?
For divorces finalized after December 31, 2018, alimony is not deductible by the payor and is not taxable income to the recipient under federal law. Most states follow the federal treatment, but check Michigan's current rules for state income tax.
Does cheating affect alimony in Michigan?
It depends on the state. Some states let courts consider marital misconduct among the alimony factors, while others bar it entirely. Review MCL 552.23 and speak with a Michigan attorney about how fault is treated where you live.
Can alimony be changed later?
Usually yes. Alimony can often be modified when there is a substantial change in circumstances — such as a large change in income, the recipient's remarriage or cohabitation, or the payor's retirement — unless your order or agreement makes it non-modifiable.
Disclaimer
This calculator provides estimates for educational purposes only and is not legal advice. Alimony is highly fact-specific and discretionary; the amount and duration a Michigan court actually orders may differ significantly from any estimate here. For advice about your situation, consult a licensed Michigan family-law attorney.
