What varies by jurisdiction
In Mississippi (US-MS), alimony and child support are handled under different statutory frameworks and then modeled separately in DocketMath using jurisdiction-aware rules. Practically, this means you generally should not blend the two into one “combined” calculation—each component has its own inputs and logic.
Mississippi — Alimony & Child Support
Mississippi uses a discretionary test — there's no bright-line statutory threshold. A judge or clerk evaluates the factors below and rules based on the full financial and situational picture. The calculator cannot compute a specific answer here, but these are the factors a court will weigh.
What the court will weigh
Gather documentation for the factors that apply to your situation — judges grant waivers more readily when the affidavit is specific.
Financial resources of the party seeking support
The financial resources of the party seeking maintenance, including marital property apportioned to that party, and the party's ability to meet needs independently.
Time needed to acquire education or training
The time necessary for the party seeking maintenance to acquire sufficient education or training to find appropriate employment.
Standard of living during marriage
The standard of living established during the marriage.
Duration of the marriage
The length of the marriage, which typically influences both the amount and duration of any support award.
Age and physical/emotional condition
The age and the physical and emotional condition of the spouse seeking maintenance.
Ability of payor to meet own needs
The ability of the payor spouse to meet his or her own needs while paying maintenance.
Contributions to the marriage
Contributions of each party to the marriage, including homemaking, childcare, and supporting the other spouse's career or education.
Tax consequences
The tax consequences of the maintenance award to each party, including post-TCJA federal treatment (no deduction/no inclusion for orders after 2018).
Marital misconduct
In some states, evidence of marital fault such as adultery or cruelty may be considered; others prohibit fault consideration by statute.
Child-care responsibilities
Whether either party has primary custody of minor children such that employment outside the home would be inappropriate or difficult.
Armstrong factors
MS courts apply Armstrong v. Armstrong (1993) factors: income/expenses, health/earning capacity, needs, obligations/assets, length of marriage, presence of minor children, age of parties, standard of living, tax consequences, fault, wasteful dissipation, other factors.

Child support: guideline-based and driven by AGI and number of children
Mississippi child support is governed by Miss. Code § 43-19-101 (child) and uses a percentage-of-obligor-AGI structure. The verified facts packet specifies the percentage steps for 1/2/3/4/5+ children as:
- 14 / 20 / 22 / 24 / 26
- described as static since 1989 in the verified packet
So, when you use DocketMath’s Mississippi child support rules, the result will change most when you change either:
- the number of children (because it selects a different percentage step), or
- the obligor’s adjusted gross income (AGI) (because the percentage is applied to AGI).
Alimony: discretionary and modeled by alimony form and duration tiers
Mississippi alimony is addressed under Miss. Code § 93-5-23 (alimony). Unlike the percentage-of-AGI guideline structure used for child support, alimony is discretionary under the statute and can take multiple forms, including:
- periodic alimony
- lump-sum alimony
- rehabilitative alimony
DocketMath’s Mississippi alimony modeling also uses the verified marriage-duration tier parameters:
- short: max years 10
- mid: min years 10 and max years 20
- long: min years 20
This setup means the alimony outcome can shift as the case moves between these tier boundaries, especially when you keep the financial inputs constant but adjust the marriage duration.
Combined takeaway
Even with the same household income facts, outcomes can diverge because:
- child support follows a percentage-of-obligor-AGI guideline approach tied to Miss. Code § 43-19-101 (child) and selected by children count
- alimony is modeled under Miss. Code § 93-5-23 (alimony) with discretionary, form-specific logic and duration tiers
Gentle disclaimer: DocketMath is a tool for planning and comparison, not a substitute for legal advice.
What to verify
Before you rely on DocketMath’s output for Mississippi, verify the inputs below so the scenario you run matches how the tool should apply US-MS rules.
1) You’re using Mississippi (US-MS) rule modules
Confirm you’re using DocketMath’s Mississippi logic:
- child support tied to Miss. Code § 43-19-101 (child)
- alimony tied to Miss. Code § 93-5-23 (alimony)
If you switch jurisdiction settings, you should expect different formulas and factor handling.
2) Child support: AGI and children count
For child support modeling under Miss. Code § 43-19-101 (child), you should be able to document and consistently enter:
- obligor AGI (the income base)
- number of children (selects the percentage step 14 / 20 / 22 / 24 / 26 for 1 / 2 / 3 / 4 / 5+)
How outputs change: holding AGI constant while changing children count will cause stepwise changes because the selected percentage changes.
3) Income-cap behavior (tool-specific rule in the verified packet)
The verified facts packet specifies DocketMath uses:
- income cap: 100000
- income cap type: presumptive
To understand how that affects your scenario, test at least two points:
- one scenario at $100,000 AGI
- another scenario above $100,000 AGI
Checklist
- Run one scenario at $100,000 AGI
- Run another scenario above $100,000 AGI
- Compare results to see whether the tool flattens or adjusts behavior under the presumptive income-cap logic
4) Alimony: marriage duration tier inputs
DocketMath’s Mississippi alimony logic uses verified tier thresholds:
- short: max years 10
- mid: min years 10, max years 20
- long: min years 20
Checklist
- Confirm marriage duration in years
- Place it into the correct tier (short / mid / long) per the verified packet
5) Alimony type selection (important under Miss. Code § 93-5-23)
Because Miss. Code § 93-5-23 (alimony) covers multiple alimony forms, verify which form best matches your scenario:
- periodic alimony
- lump-sum alimony
- rehabilitative alimony
Checklist
- Select the alimony form you want the tool to model
- Ensure the marriage-duration inputs match the verified tier definitions
Warning: Don’t assume child support and alimony are calculated the same way in Mississippi. Child support is modeled from Miss. Code § 43-19-101 (child) using percentage-of-obligor-AGI steps, while alimony is modeled under Miss. Code § 93-5-23 (alimony) with discretionary, form- and duration-tier–based logic.
Using DocketMath for Mississippi (US-MS)
To make differences easier to see, run comparison scenarios in a “single-variable-at-a-time” style:
Hold AGI constant; vary children count (1 → 5+)
- Expect step changes aligned with the 14 / 20 / 22 / 24 / 26 percentages in the verified packet for 1/2/3/4/5+ children.
Hold children count constant; vary AGI around $100,000
- Compare results at $100,000 vs. above $100,000 to see the impact of the tool’s 100000 presumptive income cap.
Hold financial inputs constant; vary marriage duration around 10 and 20 years
- Watch for changes as the scenario moves between short (≤10), mid (10–20), and long (≥20) tiers.
Run separate alimony scenarios by alimony form
- Repeat the same inputs for periodic, lump-sum, and rehabilitative selections to see how outputs differ under Miss. Code § 93-5-23 (alimony).
