Spreadsheet checks before running Closing Cost in Louisiana

What the checker catches

Running a Louisiana “Closing Cost” calculation is usually straightforward—until a spreadsheet quietly feeds the calculator the wrong inputs (or outdated assumptions). A closing-cost spreadsheet checker for Louisiana (US-LA) should validate the items that most often break totals, timelines, or compliance workflows.

Below are the high-value checks DocketMath’s closing-cost calculator workflow should confirm before you hit the calculation button.

1) Missing or malformed core inputs

A typical closing-cost sheet includes line items such as taxes, recording fees, title/settlement charges, and lender-required costs. Common spreadsheet failures include:

• Empty cells for fee amounts
• Text-formatted numbers (e.g., "1,250" stored as text)
• Negative fees entered by error (e.g., credits entered where debits belong)
• Currency columns mixed with percentage columns
• Percent fields that don’t match the fee basis

Checker outcomes

• Identify which rows are blank, non-numeric, or inconsistent
• Flag negative values (or unexpected sign changes) to prevent silent arithmetic errors

2) Date-related logic errors tied to Louisiana general prescription

Louisiana uses a prescription (statute of limitations) framework that impacts deadlines for claims. Even if your closing-cost totals don’t directly depend on prescription timing, spreadsheets often bundle date math into the same workflow.

For this Louisiana (US-LA) checker workflow, the general/default prescription period is:

• 1 year
• La. Rev. Stat. Ann. § 9:2800.9

Important: The guidance used here is general/default only. No claim-type-specific sub-rule was found in the provided jurisdiction data, so the checker treats 1 year as the baseline rather than assuming special timelines for particular claim categories.

Checker outcomes

• Confirm that the “event date” and any “deadline date” you’ve entered are valid dates
• Highlight entries where a deadline falls earlier than the modeled baseline (or where the date gap is not 1 year)

3) Spreadsheet column alignment and row mapping

Even when numbers look right, they can be mapped to the wrong fee categories. A robust checker should verify:

• Fee category names match the calculator’s expected row identifiers
• Columns for “amount,” “basis,” and “rate” aren’t shifted after copy/paste
• Totals reference the correct line-item ranges
• Summary rows are not double-counting (for example, if subtotals are included alongside their component lines)

Checker outcomes

• Detect mismatched headers
• Warn if totals include rows that should be excluded

4) Rounding and formatting drift

Closing-cost totals can differ by small amounts due to rounding. These issues are easy to miss because they may only change cents.

Common problems include:

• Rounding each line to 2 decimals and then summing vs. summing first and rounding at the end
• Using inconsistent precision for percent calculations
• Mixing display formatting (what you see) with underlying stored values (what the spreadsheet computes)

Checker outcomes

• Report the rounding method used in your sheet
• Flag cases where a rounding approach could change the cents total

5) Sanity checks for totals

A good checker includes “reasonableness” constraints to stop runaway numbers. Examples:

• Total fees = 0 when you’ve entered multiple non-zero line items
• Total negative when credits exceed debits unintentionally
• Unusually large entries (e.g., a $12,500 fee where similar fees are typically in the $200–$2,000 range in your historical sheet)

Checker outcomes

• Surface outliers so you can review the source cells
• Reduce the chance of unnoticed copy/paste, misplaced decimals, or incorrect unit entry (e.g., dollars vs. cents)

When to run it

Timing matters. Run the checker at points in your workflow where bad inputs would otherwise propagate into downstream outputs.

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.

Recommended run points (spreadsheet lifecycle)

• Before first calculation

  • After importing/exporting a lender or settlement dataset
• After any bulk edits

  • Copy/pasting fee blocks, updating rates, or changing tax assumptions
• After date changes

  • Any adjustment to “event date,” “review date,” or “deadline date”
• Before generating a PDF/export

  • Ensures the displayed totals match the numbers used for closing-cost outputs
• On every major “what-if” scenario

  • Particularly if you compare different fee structures or timing assumptions

Quick decision checklist

Because Louisiana’s general/default prescription baseline is 1 year under La. Rev. Stat. Ann. § 9:2800.9, date validation is a key guardrail when your spreadsheet workflow includes deadline computations—even if the closing-cost numbers themselves aren’t dependent on prescription timing.

Try the checker

You can test this right away with DocketMath’s closing-cost tool:

1. Open the calculator here: ** /tools/closing-cost
2. Run the checker on your spreadsheet inputs by doing the following:

   • Load or copy the fee lines into the tool’s input structure
   • Confirm date fields are real dates (not text)
   • Verify you’re using 1 year as the default baseline for any prescription-related deadline logic under La. Rev. Stat. Ann. § 9:2800.9

What to expect when inputs are correct

• Totals compute consistently with line items
• Rounding produces stable cent-level results
• Date gap validation shows conformity with the 1-year baseline used for this general/default rule set

What to expect when something is off

DocketMath’s spreadsheet checks typically surface problems like:

• Non-numeric fee entries that would otherwise become zeros or NaNs
• Misaligned fee category rows (for example, an amount intended for “recording fee” fed into “taxes”)
• Dates that don’t parse—leading to incorrect deadline math
• Unexpected negative values in debit/credit sections

If you want to verify the whole workflow end-to-end, start small:

• Feed in 3–5 line items
• Add one date field
• Confirm the checker passes
• Then expand to the full closing-cost sheet
