Missouri Alimony Calculator
Build a planning estimate for Missouri maintenance from both incomes and marriage length. Courts apply Mo. Rev. Stat. §452.335 factors — this tool shows a transparent difference-% amount plus duration bands. Click any i for detail.
Missouri planning inputs
Income figures are
i
Income basis
Use comparable figures for both spouses (both annual or both monthly). |
|
|---|---|
Payor income ($)
i
Payor income
Spouse with greater ability to pay. Net is preferable when available. |
|
Recipient income ($)
i
Recipient income
Spouse seeking support — include wages and steady other income. |
|
Marriage length (years)
i
Marriage length
Missouri duration discussions often track short / moderate / long marriages. We sketch a duration ceiling from your years married. |
|
Share of income difference (%)
i
Difference share
Planning dial for amount. Missouri does not mandate this percent — adjust to match settlement talks. |
How to use this calculator

- Compare the monthly estimate with the modeled duration band.
Results explained
Missouri support is factor-based under Mo. Rev. Stat. §452.335. This calculator uses a share of income difference and marriage-length duration fractions for stress-testing — not a court order.

How the estimate is built
Annual sketch = diff% × max(0, payor − recipient). Monthly = annual ÷ 12. Duration sketch uses marriage-year × band factor.
Example scenario
Payor $135,000, recipient $48,000, 40% difference → gap $87,000 → ~$34,800/year (~$2,900/month). Fourteen-year marriage → mid-band duration sketch.
FAQ
Is there a Missouri guideline formula?
Missouri has no single statewide amount formula used here — courts weigh statutory factors (Mo. Rev. Stat. §452.335). This page is a planning sketch only.
Temporary vs long-term?
This page does not separate temporary orders from long-term awards — map types with your attorney.
Child support first?
Child support affects ability to pay. Model child support separately before locking maintenance.
Tax treatment?
Federal tax treatment of alimony depends on divorce date and agreement terms — not modeled here.
