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:
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).
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.
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.
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.
**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.
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.
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)
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 change | Keep constant | Expected direction of change |
|---|---|---|
| Event/start date | All fees + principal | Total increases if the SOL-covered window lengthens |
| As-of date | Event date + principal | Total increases if more time accrues |
| Principal amount | Dates + fee categories | Total scales up/down with principal-dependent parts |
| Fee category inclusion | Dates + principal | Total shifts by exactly the included component(s) |
| Accrual frequency/rounding | Same dates + categories | Total may differ even with identical “business logic” otherwise |
- 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:
