Why Closing Cost results differ in Mississippi

The top 5 reasons results differ

If you’re seeing different Closing Cost outcomes in Mississippi (US-MS) using DocketMath, the cause is usually traceable to one of these five issues. Mississippi’s general/default statute of limitations (SOL) period is 3 years under Miss. Code Ann. § 15-1-49. Also, no claim-type-specific sub-rule was found, so differences generally don’t come from switching to a shorter/longer SOL category—rather, they come from inputs, timing, and how the calculation applies the same 3-year window.

Here are the most common drivers:

  1. Different “event date” used to start the 3-year SOL window

    • DocketMath’s closing-cost results can change materially if users treat different dates as the trigger (for example: contract signing vs. default date vs. filing date).
  2. Mismatched “as-of” date for the calculation

    • A later “as-of” date can increase amounts that accrue over time, affecting totals when the tool calculates what falls within (and/or beyond) the SOL-covered timeframe.
  3. Inconsistent debt/principal assumptions

    • Small changes to the principal or how unpaid amounts are defined can ripple through percentage-based components, caps, or derived fees that depend on the starting amount.
  4. Fee components toggled or categorized differently

    • Closing-cost tools often separate totals into categories (e.g., recording-related costs, service fees, attorney-related line items, and other closing add-ons). If one run includes a category another run omits, totals won’t match.
  5. **Rounding and accrual frequency differences (monthly vs. per-day)

    • Two runs can diverge if one calculation uses daily accrual while another uses monthly accrual—or if values are rounded at different steps.

Pitfall: The most frequent “mystery discrepancy” is that two runs use different start dates for the SOL-covered window, so the same fee logic is applied over different time spans.

How to isolate the variable

To pinpoint the exact reason for the mismatch, use a controlled comparison—only change one input at a time.

  1. Lock the Mississippi baseline first

    • Use the general/default 3-year SOL: Miss. Code Ann. § 15-1-49.
    • Because no claim-type-specific sub-rule was found, don’t swap to an alternate SOL period unless you have a separate, clearly documented basis.
  2. Run two calculations with one change Focus on the smallest realistic difference that could explain the delta, such as:

    • Event/start date
    • As-of date
    • Principal amount
    • Which fee categories are included/excluded
    • Accrual frequency/rounding option (if available in DocketMath)
  3. Use a simple “difference table” Capture the same set of outputs from both runs—typically:

    • Baseline total
    • Time span used (days/months)
    • Each major fee category
    • Any interest/accrual component (if shown)
What you changeKeep constantExpected direction of change
Event/start dateAll fees + principalTotal increases if the SOL-covered window lengthens
As-of dateEvent date + principalTotal increases if more time accrues
Principal amountDates + fee categoriesTotal scales up/down with principal-dependent parts
Fee category inclusionDates + principalTotal shifts by exactly the included component(s)
Accrual frequency/roundingSame dates + categoriesTotal may differ even with identical “business logic” otherwise
  1. Sanity-check that the effective window matches 3 years
    • Since the general period is 3 years, results that implicitly treat the covered window as shorter/longer based on your chosen dates are a strong sign you’re not comparing apples-to-apples.

Next steps

Once you isolate the cause, you can make your inputs consistent and your results reproducible:
