Spreadsheet checks before running Closing Cost in Idaho

What the checker catches

Run this scenario in DocketMath using the Closing Cost calculator.

Before you run Closing Cost calculations in Idaho, DocketMath’s spreadsheet checker is built to catch the kinds of input problems that most often cause results to change after the fact—especially mistakes involving timing.

In Idaho, the key timing concept (for this workflow) is the general statute of limitations (SOL) period. Idaho sets a 2-year general SOL period in Idaho Code § 19-403. Because no claim-type-specific sub-rule was found for this particular closing-cost spreadsheet workflow, this checker uses the general/default 2-year period rather than any specialized period.

In practice, the checker validates your spreadsheet inputs so you don’t accidentally feed the calculator dates and fields that can’t be right under the Idaho timing assumption. Here are the main checks it’s designed to run:

  • Missing or invalid dates
    • Flags blank “event date” fields, dates entered in the wrong format (for example, as plain text), or impossible dates (like 02/30).
  • Date order issues
    • Detects scenarios where the timeline can’t logically be true (for example, a “filing date” that appears earlier than the “event date” used to start the SOL clock).
  • SOL window misalignment
    • Verifies whether your date range fits the 2-year window under Idaho Code § 19-403 (general/default SOL period).
  • Off-by-one and day-count inconsistencies
    • Spreadsheet date logic sometimes counts days differently (for example, inclusive vs. exclusive). The checker looks for consistency so your timeline math doesn’t “drift.”
  • Wrong worksheet references
    • If your Closing Cost inputs are pulled from the wrong tab or column, you can still get a “clean-looking” output—based on incorrect data. The checker is meant to catch common reference mix-ups.
  • Unit and rounding issues
    • Helps identify cases where money fields are entered inconsistently (for example, “12500” instead of “12,500.00”) or where formatting mixes dollars/percent-like values.

Gentle warning: Even when the math looks precise, bad or mismatched dates can still produce confidently wrong outputs. A spreadsheet can pass a “math sanity check” while failing a “jurisdiction timing” check—particularly around the SOL window assumption. This checker targets that gap.

Idaho timing rule used by the checker (general/default for this workflow):

Disclaimer: This is a practical spreadsheet-validation step, not legal advice. SOL timing can depend on case-specific facts, and claim types may affect analysis in ways this general checker does not automatically model.

When to run it

Run the checker before you execute DocketMath Closing Cost and before you export or share results. A reliable sequence looks like this:

  1. Build or refresh your spreadsheet inputs
    • Populate every date field your model uses.
    • Confirm currency and percentage fields are consistently formatted.
  2. Run the spreadsheet checker
    • Validate:
      • date presence and formatting
      • timeline order
      • 2-year general SOL alignment (per Idaho Code § 19-403 for this workflow)
      • reference integrity (correct worksheet/tab/column links)
  3. Run DocketMath Closing Cost
    • Once the checker reports no blocking input issues, proceed with the calculation.
  4. Re-run after edits
    • Any time you change an event date, filing date, or a date-derived field, rerun the checker.

Practical “trigger” list

Re-check whenever you:

  • update a transaction/event date
  • adjust a deadline or filing date
  • copy values between tabs (references often shift)
  • change how you format dates (for example, from “Jan-3” to “2026-01-03”)

How outputs change when the checker finds problems

If the checker flags an issue, the most common effects are:

  • Timing adjustment: your dataset may fall outside the 2-year window (or your start date may be wrong).
  • Calculation integrity change: the Closing Cost result may still compute, but the assumptions behind the timeline (and therefore the interpretation of the output) become unreliable.
  • Auditability improvement: you’ll have clearer evidence of what broke (for example, “event date missing” or “date order impossible”), which makes it easier to fix the spreadsheet quickly.

Try the checker

You can start the workflow directly here: /tools/closing-cost. Use that as your entry point, then run the spreadsheet checker portion first to validate inputs before relying on the calculated output.

Inline checklist for Idaho (US-ID):

Idaho timing reference used by the checker:

  • General/default SOL = 2 years under Idaho Code § 19-403
  • No claim-type-specific sub-rule was found for this closing-cost spreadsheet workflow, so the checker relies on the general period.

If you get a timing warning after running the checker, don’t just overwrite it—review the actual date inputs. Most timing issues come from:

  • swapped columns (event vs. filing vs. comparison)
  • a single cell formatted as text (so it doesn’t behave like a true date)
  • “clever” date formulas that return empty strings
  • copied dates into the wrong row range

Pitfall to watch: A spreadsheet can show “no error” while still using the wrong date cell. The checker’s reference-validation step is meant to catch exactly that kind of silent mismatch before the Closing Cost calculator turns bad inputs into confident-looking numbers.
