What the checker catches

Running a Washington “Closing Cost” calculation without screening the spreadsheet inputs can quietly create downstream errors—especially when the spreadsheet’s rows, dates, and assumptions don’t line up with Washington’s general statute of limitations (SOL) framework.

DocketMath’s Closing Cost tool is most accurate when your spreadsheet already passes a few jurisdiction-aware checks. Here’s what a good “spreadsheet checker” catches before you calculate closing-related amounts for US-WA.

1) Missing or mis-ordered key dates

A typical closing-cost spreadsheet includes dates like:

Accrual date (when the relevant event occurred)
Notice or demand date (if applicable to your workflow)
Filing date (when you plan to submit or document)
Computation end date (sometimes implicit)

The checker flags problems such as:

Blank date cells
Dates stored as text (e.g., 01/15/2026 entered as a string)
Chronology violations (e.g., filing date earlier than accrual date)

Why it matters in Washington: the tool’s results can be distorted if SOL screening logic is fed incorrect date order. For this checker workflow, Washington’s general SOL period is 5 years under RCW 9A.04.080.

Pitfall: If your spreadsheet has an “MM/DD/YYYY” string that spreadsheet software interprets inconsistently, your SOL window calculation can flip—leading to a “timely” classification when it should be “out of window,” or vice versa.

2) SOL window mismatches (jurisdiction-aware)

Washington’s jurisdiction data for this workflow uses:

General SOL period: 5 years
General statute: RCW 9A.04.080

Important: In this checker run, no claim-type-specific sub-rule was found, so the workflow uses the default general period. That means:

The checker applies 5 years as the baseline SOL window
It does not switch to a different SOL based on a claim subtype—unless you explicitly encode that logic elsewhere

3) Incomplete scope of charges/cost components

Closing-cost spreadsheets often break costs into components (e.g., fees, adjustments, third-party charges). The checker verifies:

Every cost component has a value or a clear “not applicable” indicator
You don’t accidentally skip a row after copy/paste
Units are consistent (e.g., dollars vs. cents)

If the tool expects numeric fields but finds blanks, the checker can prevent totals from silently undercounting.

4) Inconsistent naming that breaks mapping

DocketMath calculations rely on your spreadsheet structure lining up with expected fields. The checker catches:

Duplicate column headers
Similar-but-not-identical labels (e.g., Closing Cost vs. Closing costs)
Columns shifted by one position due to an added column mid-sheet

5) Negative or impossible numbers

Some spreadsheets accidentally produce:

Negative fees (often caused by sign conventions in formulas)
Percent fields expressed inconsistently (e.g., 3 meaning 3% vs. 3.0)

The checker flags these so your Closing Cost output doesn’t look precise but be wrong underneath.

When to run it

Run the spreadsheet checker at the moment you’re about to compute, not after you’ve already shared totals or exported reports.

Use this timing approach:

Run the checker before importing a spreadsheet into the Closing Cost workflow. It is especially helpful when you have multiple entries or when a teammate provided the inputs.

Best point in the workflow

Before you open DocketMath’s Closing Cost calculator.
After you finalize inputs (dates, amounts, component rows).
Before you export figures into emails, case chronologies, or settlement summaries.

Recommended cadence

Initial pass: Right after importing a spreadsheet or rebuilding a template.
Pre-calculation pass: Every time you update the filing date, accrual date, or any cost component.
Pre-export pass: Immediately before you submit or share your results.

Quick checklist for “go/no-go”

Use these checks to decide whether to proceed:

Warning: If you update only one date but not dependent date-driven calculations (like “years elapsed”), formulas can remain stale. The checker helps detect that mismatch before you run Closing Cost.

Here’s how to think about inputs and outputs with a Washington-focused run (US-WA):

Upload the spreadsheet, review the warnings, and then run the calculation once the inputs are clean: Try the checker.

What you enter (typical inputs)

Accrual date
Filing date (or your computation reference date)
Cost components (fees/charges/line items)
Any percentage or adjustment parameters your spreadsheet uses

What the checker does

Before calculating, DocketMath’s spreadsheet checker:

Validates date integrity (format + chronology)
Applies the general SOL period of 5 years under RCW 9A.04.080
Confirms the spreadsheet structure is consistent enough for mapping
Helps prevent math drift from blanks, shifts, or impossible values

How outputs change when inputs are fixed

To make the impact concrete, watch what happens when a single variable changes:

Scenario	Input change	Checker outcome	Closing Cost impact
A	Accrual date entered as text	Date parsing flagged	Prevents unreliable SOL window logic
B	Filing date earlier than accrual	Chronology flagged	Blocks or warns before SOL-based classification
C	Missing one fee component	Components incomplete	Totals won’t undercount silently
D	SOL window crossing due to updated filing date	SOL classification changes using 5-year default	Downstream totals and timing-sensitive outputs adjust accordingly

Because Washington’s workflow here uses the default general 5-year SOL (per RCW 9A.04.080) and no claim-type-specific override was identified in this run, your SOL classification should move strictly as that 5-year window is crossed based on the dates you provide.
