Why Closing Cost results differ in Wisconsin

The top 5 reasons results differ

If you run a Closing Cost calculation in Wisconsin (US-WI) with DocketMath, you may see different results across runs, files, or scenarios. Those differences usually trace back to a small set of jurisdiction-aware inputs and rules.

Here are the top 5 reasons closing-cost results differ in Wisconsin:

1. Different statute-of-limitations (SOL) assumptions

   • Wisconsin’s general SOL for criminal statutes is 6 years under Wis. Stat. § 939.74(1).
   • In the provided jurisdiction data, no claim-type-specific sub-rule was found. So DocketMath should use the general/default 6-year period as the basis.
   • If an input date lands near the boundary of that 6-year window, small changes can flip whether the model treats costs as “within time” versus “time-barred” (depending on the calculation’s internal logic).

2. Misalignment of the key date you choose Closing-cost outputs often depend on one or more date inputs, such as:

   • event/filing date (or the trigger date for the timing window)
   • measurement/valuation date
   • any start/end window date(s) for cost components
     If one run uses an earlier start date (or a different end date), the calculated time window changes, and the totals can move materially.

3. Different assumptions about “what costs belong” DocketMath’s closing-cost calculator typically aggregates a set of cost lines. Even if the timing is identical, totals can change if the runs:

   • include different fee categories, or
   • exclude a component unintentionally (for example, one run omits a category due to mapping/defaults rather than an intentional choice).

4. Rounding and currency formatting differences Tools sometimes round at different stages (per line/per period, or only at the final sum). Two workflows that differ only in rounding can produce small-but-noticeable discrepancies—especially when there are many components.

5. Jurisdiction-aware rules applied inconsistently DocketMath is designed to apply US-WI rules. If one scenario is accidentally run with a different jurisdiction setting, or if a mixed-jurisdiction dataset is used, the SOL window and timing logic can change—leading to divergent outputs.

How to isolate the variable

To find out why your Closing Cost totals differ, isolate one factor at a time when comparing two DocketMath runs.

Use this checklist while comparing your two scenarios:

• DocketMath should apply 6 years under Wis. Stat. § 939.74(1) (general/default rule)

A practical method:

1. Start with the two runs that disagree the most.
2. Re-run one scenario and change only one variable (for example, the event/trigger date).
3. If the output flips or jumps, that variable is likely the driver.
4. Repeat until you narrow the difference to a single “difference source.”

Next steps

Once you isolate the variable, you can tighten your analysis without guessing:

• If the difference comes from timing:

  • Standardize your date definitions and document what each date field means (event/trigger, start, end, measurement/valuation).
  • Keep the same date logic across all scenarios.
• If the difference comes from cost line selection:

  • Lock the cost taxonomy (the exact list of fee categories included).
  • Exclude items only if you also exclude them consistently across every comparison run.
• If the difference comes from rounding:

  • Align rounding settings and/or record how totals were rounded.
• If the difference seems unrelated to input changes:

  • Re-check that US-WI rules are actually being applied in every run, including the general 6-year SOL basis under Wis. Stat. § 939.74(1).

Gentle disclaimer: This guidance focuses on modeling and calculation differences, not legal outcomes. If your work depends on legal conclusions, treat calculation outputs as decision-support and verify assumptions against the full factual record and applicable law.
