Missouri Spousal Support Calculator

1. What is Missouri Spousal Support (Maintenance)?

In Missouri, spousal support is formally referred to as "maintenance." It is financial assistance paid by one spouse (the "payor") to the other (the "recipient") after a divorce. The purpose of Missouri spousal support is to provide for the reasonable needs of a spouse who lacks sufficient property, including marital property apportioned to them, to provide for their reasonable needs, and is unable to support themselves through appropriate employment. Unlike some states with strict formulas, Missouri courts have significant discretion when determining if maintenance should be awarded, and if so, the amount and duration of payments.

This Missouri Spousal Support Calculator is designed to help individuals understand a potential estimate, but it is crucial to remember that it is not a legal guarantee. Those considering divorce or already in the process in Missouri should consult with a qualified family law attorney in Missouri to discuss their specific circumstances.

2. Missouri Spousal Support Calculator Formula and Explanation

Because Missouri law does not provide a rigid formula for calculating spousal support, this calculator employs a common heuristic used for initial estimations. It considers the adjusted gross incomes of both parties and the duration of the marriage.

Our Simplified Estimation Model:

1. Adjusted Payor's Monthly Income (API): Payor's Gross Monthly Income - Monthly Child Support Paid by Payor
2. Adjusted Recipient's Monthly Income (ARI): Recipient's Gross Monthly Income + Monthly Child Support Received by Recipient
3. Income Difference (ID): API - ARI (If API is greater than ARI, otherwise $0)
4. Estimated Monthly Spousal Support: ID × (Support Percentage Factor / 100)
5. Estimated Duration of Support: Marital Duration (Years) × 0.4 (capped at 20 years for calculation purposes, as indefinite maintenance is rare but possible for very long marriages).

This formula provides a starting point. Courts in Missouri will consider many other factors, as outlined in Section 452.335 RSMo, before making a final determination. The "Support Percentage Factor" in our calculator is an adjustable variable because the court's discretion means there is no fixed percentage.

5. Key Factors That Affect Missouri Spousal Support

Missouri courts consider numerous factors when deciding on maintenance, as outlined in Section 452.335 RSMo. Our calculator simplifies these for an estimate, but a judge's decision will be based on a thorough review of:

• Financial Resources of the Spouse Seeking Maintenance: This includes marital property apportioned to them, their ability to meet their needs independently, and any child support received.
• Time Required for Education or Training: The period necessary for the recipient spouse to acquire appropriate education or training to find suitable employment.
• Standard of Living During the Marriage: The lifestyle established during the marriage is a significant consideration.
• Duration of the Marriage: Longer marriages often correlate with longer or higher maintenance awards, especially if one spouse has been out of the workforce for an extended period.
• Age and Physical/Emotional Condition of the Spouse Seeking Maintenance: Health issues or advanced age can impact a spouse's ability to become self-supporting.
• Ability of the Payor Spouse to Meet Their Needs While Paying Maintenance: The court must ensure the payor can afford to pay maintenance while also meeting their own reasonable needs.
• Conduct of the Parties During the Marriage: While less common for maintenance calculations, marital misconduct (e.g., adultery) can sometimes influence a judge's decision in Missouri, though it's not a primary factor for the amount.
• Custodial Arrangements for Children: If a spouse is the primary caregiver for a child whose condition or circumstances make it inappropriate for them to work outside the home, this can be a factor.

These factors mean that every Missouri spousal support case is unique, and outcomes can vary significantly based on individual circumstances.

6. Frequently Asked Questions (FAQ) About Missouri Spousal Support

Q2: How is the duration of spousal support determined in Missouri?
