Why Alimony Child Support results differ in North Dakota

The top 5 reasons results differ
Run this scenario in DocketMath using the Alimony Child Support calculator.
If you run the DocketMath: alimony-child-support calculator for North Dakota (US-ND) and notice your results don’t match someone else’s, the difference is usually traceable to a small set of inputs and North Dakota-specific modeling rules. The calculator is designed to be jurisdiction-aware, but “garbage in, garbage out” still matters—especially in support calculations where small changes can swing the output.
Pitfall: Two people can use the same calculator name (“alimony + child support”) and still be running different scenarios—different income definitions, different time frames, or different health/deduction assumptions.
Here are the top 5 reasons results differ most often in North Dakota:
**Income used for each party differs (gross vs. net, verified vs. estimated)
- Even within the same jurisdiction, one scenario may include additional income streams (overtime, bonuses, self-employment adjustments) while another uses a narrower figure.
- Output impact: Monthly support figures can change directly because the algorithm is driven by available income inputs.
**Child support is affected by custody allocation (parenting time / number of overnights)
- Different custody schedules can shift the formula output in a way that’s often larger than expected.
- Output impact: Child support can move noticeably even when incomes stay constant.
DocketMath assumptions about deductions and mandatory payroll items
- If one set of inputs includes taxes, health insurance cost, or other recurring deductions differently than the other, the “effective” income can change.
- Output impact: Both child support and alimony estimates can shift because each component uses the net/available-income logic behind the scenes.
Alimony duration and “step” behavior assumptions
- Alimony outcomes often reflect scenario settings—how long payments are modeled to continue, and whether the output is treated as shorter-term vs. longer-term obligation.
- Output impact: The same incomes can still produce different ranges if the duration toggles differ.
Special circumstances you may or may not be encoding
- Examples include health coverage, extraordinary child expenses, or income that varies year-to-year.
- Output impact: The calculator reflects what you enter; if those items aren’t represented consistently, the outputs can diverge.
How to isolate the variable
To pinpoint why your North Dakota results differ, treat it like a debugging exercise. Use DocketMath iteratively and change one input at a time. A reliable way to isolate the variable is a paired comparison:
- Freeze the jurisdiction and tool settings so both runs use the same rule set.
- Compare one input at a time (dates, rates, amounts) and re-run after each change.
- Review the breakdown to see which segment or assumption drives the difference.
Step-by-step isolation workflow
- Create two scenarios
- Scenario A = your current inputs
- Scenario B = the other person’s inputs (or a “matching” version of them)
- Freeze everything except one category.
- Change only one input per run and record the delta.
Recommended “change one thing” checklist
Start with the inputs that most often drive variance:
- Base salary vs. bonus included?
- Self-employment averaged or single-year?
- Overnights per year set correctly?
- Children count and coverage consistent?
- Premium included monthly?
- Who pays it in your scenario?
- Payroll deductions entered in the same style?
- Duration assumptions matched?
If the difference is small after a change, move to the next category. If it jumps dramatically, you’ve likely found the driver.
Quick comparison table
| Input category | Scenario A | Scenario B | Output delta (child / alimony) | Likely cause |
|---|---|---|---|---|
| Income definition | $____ | $____ | $____ / $____ | Income base |
| Parenting time | ____ overnights | ____ overnights | $____ / $____ | Custody schedule |
| Health insurance | $____ | $____ | $____ / $____ | Deduction/expense |
| Alimony duration | ____ years | ____ years | $____ / $____ | Duration model |
| Other expenses | $____ | $____ | $____ / $____ | Expense inclusion |
For additional context on how the tool structures its inputs, begin with the calculator UI at /tools/alimony-child-support and cross-check the related questions shown in the broader /tools area.

Next steps
Once you’ve isolated the input that drives the variance, you can move from “why different?” to “what should we do with this?”
- Run 3–5 sensitivity checks
- Make small adjustments (for example, income ±5% or ±$100–$300/month for insurance) to see whether the output is stable or highly sensitive.
- Standardize your input style
- Use the same time window (monthly average vs. annualized).
- Use the same custody measurement (overnights).
- Use the same monthly health premium figure.
- Save your scenario set
- Keep a versioned record (Scenario A, Scenario B, and each “single variable changed” run). This makes it easier to explain what changed and why.
- Prepare for human review without guessing
- Use DocketMath outputs as scenario estimates, then align your next step to the specific questions you still can’t verify in the inputs.
Warning: If you copy numbers from pay stubs, spreadsheets, or prior filings, ensure they match the calculator’s expected monthly format—entering annual figures as monthly values is a common source of extreme mismatch.
