Inputs you will need
Run this scenario in DocketMath using the Alimony Child Support calculator.
Before you run DocketMath’s alimony-child-support calculator for Missouri (US-MO), gather the inputs that most directly affect the results. Child support and spousal maintenance (often called “alimony”) use different rules, but the calculator workflow still benefits from having consistent, verified facts in hand.
Below is a practical checklist of what to collect. If you’re missing something, you can still enter partial information, but your output may be incomplete or less accurate.
Child support inputs (typical)
Spousal maintenance (alimony) inputs (typical)
Missouri timing note (general): Missouri uses a default 5-year general statute of limitations period referenced in Mo. Rev. Stat. § 556.037. That section provides the general rule for limitations timing; it is not a claim-type-specific rule for alimony or child support in the information provided here. Use it only as a general timing reference, not as a substitute for case-specific guidance.
Timing inputs (often overlooked)
Where to find each input
To keep your workflow smooth in DocketMath, pull each input from documents you can trust. Use this “evidence map” to locate and verify figures.
| Input | Where to find it | What to look for |
|---|---|---|
| Gross monthly income | Pay stubs, W-2s, employer letters | Use consistent time periods (e.g., monthly average) |
| Other income | Tax returns, benefit statements | Bonuses, overtime, commissions, unemployment, SSI/SSDI (as applicable) |
| Parenting time schedule | Proposed custody plan, court order, shared calendar | Overnights and week/month rhythm |
| Children’s number | Birth certificates / case caption | Ensure the calculator reflects the correct count |
| Health insurance cost | Premium statements or payroll deductions | Amount attributable to children |
| Childcare costs | Receipts, daycare invoices | Monthly totals and payment method |
| Marriage length | Marriage certificate + dates | Convert to years/months |
| Health/age factors | Medical notes, HR documentation | Keep it factual and current |
| Monthly living expenses | Budget worksheet + statements | Rent, utilities, car payments, transportation |
For best results, standardize your numbers:
- Use monthly amounts (not weekly) unless DocketMath instructs otherwise.
- If your income fluctuates, consider your recent average (for example, a trailing 3–12 month average) rather than a single paycheck.
- Document parenting time in a way that’s unambiguous (for example, “Parent A has every other weekend + 2 midweek overnights”).
Caution: If you guess income or over-simplify parenting time (for example, “50/50” without confirming overnights), your DocketMath output can move meaningfully. Courts typically focus on actual schedules and verifiable earnings.
Run it
Once you’ve assembled the checklist above, you’re ready to run the calculator.
- Open DocketMath alimony-child-support: /tools/alimony-child-support
- Enter the required inputs in the calculator’s step-by-step flow:
- Start with child-related information (children, incomes, parenting time).
- Then input spousal maintenance factors (marriage length, income, and other relevant considerations).
- Review outputs and test sensitivity:
- If you change parenting time, child support output can change even with the same incomes.
- If you change income inputs, both child support and maintenance calculations may shift.
- If you add or remove verified costs (health insurance or childcare), expect adjustments rather than “minor rounding.”
How outputs typically change when you adjust inputs
Use these scenario prompts to sanity-check your results:
- Scenario A: Parenting time changes
- Same incomes, but different overnights → child support output usually changes.
- Scenario B: Income changes
- Higher gross income for one parent → results typically skew accordingly for the other parent’s obligation calculations.
- Scenario C: Add childcare / insurance costs
- Adding verified monthly costs → child-related totals can increase.
Missouri timing & limitations (general)
If your case involves timing questions, don’t rely only on general timelines. The note about Mo. Rev. Stat. § 556.037 (general 5-year limitations) is not a substitute for how courts treat support start dates, modifications, or enforcement specifics. For the exact application in your situation, consider speaking with a qualified attorney or reviewing official court guidance.
Good-faith reminder: This tool is for planning and estimation. Feeding DocketMath consistent, document-backed numbers—especially for income and parenting time—tends to produce the most useful outputs.
