Why Closing Cost results differ in Arizona

The top 5 reasons results differ

Run this scenario in DocketMath using the Closing Cost calculator.

If you’re running the DocketMath “closing-cost” calculator for Arizona (US-AZ) and your outputs don’t match what you expected, the differences usually come from inputs and jurisdiction-aware rule handling—not from the tool “changing.” Even small shifts in dates or assumptions can move results.

Below are the top 5 causes we see when people compare results across scenarios in Arizona.

1. Confusing the default SOL window with a claim-specific window

   • Arizona’s general rule for criminal statute of limitations (SOL) is 2 years under A.R.S. § 13-107(A).
   • Your brief indicates no claim-type-specific sub-rule was found, so the tool (and your scenario) should treat this as the default period.
   • If another workflow used a different period (or a claim-specific override), the closing cost results can diverge even with the same fee inputs.

2. **Date boundary effects (exact day matters)

   • SOL calculations depend on the start and end dates you enter (for example, an event date vs. a filing or milestone date).
   • A one-day shift can move a scenario from “within 2 years” to “outside 2 years,” which can change how the scenario is classified—and that can impact the closing cost output.

3. Jurisdiction mismatch in cross-state scenarios

   • DocketMath applies jurisdiction-aware rules.
   • If you accidentally use dates or assumptions that were prepared under another state’s workflow, but then run them under US-AZ, the outputs may not align with your expectations.

4. Mismatched assumptions about which cost components are included

   • “Closing cost” models depend on which cost buckets/components you include as inputs.
   • If one run includes fewer components (or a different fee schedule basis) while the other run includes more, the totals can differ even when SOL timing is identical.

5. Premature or delayed “effective” milestone date entry

   • Many real-world workflows hinge on a key operational milestone (often acting like an “effective” date), such as a notice date, service date, or similar trigger.
   • Entering the wrong milestone date changes the SOL timeline, and depending on your DocketMath setup, that can alter the scenario outcome used by the calculator.

How to isolate the variable

Use this repeatable diagnostic approach to pinpoint what’s driving the mismatch.

• 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 checklist (repeatable)

Practical “single-variable reruns”

Do three targeted reruns and record each output:

This approach makes the cause obvious: the mismatch is either driven by SOL timing boundary inputs or by cost-component configuration.

Next steps

1. Standardize your date definitions

   • Write down which real-world milestone maps to your “start date” and “end date.”
   • If that mapping varies between runs, your comparisons won’t be apples-to-apples.

2. Use Arizona’s default SOL consistently

   • Arizona’s general SOL is 2 years under A.R.S. § 13-107(A).
   • Because no claim-type-specific sub-rule was found, avoid silently switching to other periods in your own process.

3. Document your DocketMath inputs before comparing

   • Capture at minimum:

     • jurisdiction (US-AZ)
     • SOL start date
     • SOL end date
     • enabled cost components

4. Treat unexpected differences as a data-quality signal

   • Most discrepancies come from input drift (dates or enabled buckets), not from a “rule conflict.”

Note (not legal advice): This is a diagnostic, informational explanation. If your situation depends on a specific claim type or a special procedural timeline, the default A.R.S. § 13-107(A) assumption may not fully match every real-world pathway.
