Worked example: Closing Cost in Florida

Example inputs

Run this scenario in DocketMath using the Closing Cost calculator.

Below is a worked example showing how to estimate a closing cost number in Florida using DocketMath and jurisdiction-aware rules for Florida’s general timeline logic. You can try the same workflow here: /tools/closing-cost.

This example focuses on the time-based component reflected in the DocketMath closing-cost calculator (for example, how long something runs before a cost outcome is triggered). It does not attempt to cover every fee category that may apply in a real transaction.

Scenario (Florida / US-FL)

Assume a user is modeling a matter with these inputs:

• Jurisdiction: US-FL (Florida)
• Start date: 2026-01-15
• End date / trigger date (derived): 2026-05-15

  • That’s a span of 120 days (about 4 months).
• Base filing/processing amount: $1,500
• Daily rate multiplier: $8.50 per day
• One-time closing fee: $250
• Estimated time window rule: Use Florida general default period when a claim-specific rule is not found.

Florida rule used (general default)

For this worked example, no claim-type-specific sub-rule was found, so DocketMath uses the general/default period:

• General Statute: Florida Statute **§ 775.15(2)(d)
• General SOL / period: 4 years

Important note (dataset constraint): This example uses Florida’s general default period (4 years) because the walkthrough did not identify a claim-type-specific sub-rule. That means the calculation is governed by the general rule rather than a specialized shorter/longer rule.

Example run

Let’s run the numbers as DocketMath would, using the jurisdiction-aware setup for Florida (US-FL) and the 4-year general default period from Fla. Stat. § 775.15(2)(d).

Run the Closing Cost calculator using the example inputs above. Review the breakdown for intermediate steps (segments, adjustments, or rate changes) so you can see how each input moves the output. Save the result for reference and compare it to your actual scenario.

Step 1: Confirm the time span against the general default period

• Modeled span: 120 days
• General default period: 4 years

  • 4 years ≈ 1,460 days (practical approximation for this example)

Because 120 days < 1,460 days, the model treats the matter as occurring within the default period window.

Step 2: Compute a time-weighted cost component

In this walkthrough, DocketMath’s closing-cost calculation is represented with a simple structure:

1. Time-based component = (Number of days) × (Daily rate multiplier)
2. Add fixed/one-time fees = base amount + one-time closing fee
3. Apply any closing adjustment tied to the time window

   • In this example: none additional, since we’re within the general default window and no claim-type-specific deviation was identified.

Using the inputs:

• Time-based component = 120 days × $8.50/day = $1,020
• One-time amounts = Base $1,500 + Closing fee $250 = $1,750

Step 3: Total estimated closing cost output

Total closing cost estimate:

• $1,750 + $1,020 = $2,770

✅ DocketMath output (this example run): $2,770

Sensitivity check

Real modeling rarely uses a single date range and a single daily multiplier. To show how the closing-cost estimate changes, here are three targeted sensitivity tests. Each one keeps everything constant except the factor being tested.

Disclaimer: This is a modeling exercise to illustrate how the calculator responds to inputs. It isn’t legal advice and won’t account for every real-world fee schedule, contract term, or procedural change.

Sensitivity A: Change the trigger window length (days)

Keep:

• Base amount = $1,500
• Daily multiplier = $8.50
• One-time closing fee = $250
• Florida default period rule remains 4 years (Fla. Stat. § 775.15(2)(d))

Run three versions:

Takeaway: Every extra day adds $8.50 to the estimate in this simplified structure, as long as the modeled window continues to be treated under the same general default logic.

Sensitivity B: Change the daily rate multiplier

Keep:

• Days = 120
• Base amount = $1,500
• One-time closing fee = $250

Takeaway: The daily multiplier scales the time-based component directly, which often has a larger impact than one-time fees when the timeline is long.

Sensitivity C: Crossing the 4-year default period (rule boundary check)

This test is focused on the jurisdiction-aware guardrail effect. For Florida, the general default period used here is 4 years under Fla. Stat. § 775.15(2)(d).

Keep:

• Base amount = $1,500
• Daily multiplier = $8.50
• One-time closing fee = $250

Compare:

• Within default: 1,000 days
• Beyond default: 1,600 days (clearly exceeds 4 years ≈ 1,460 days)

Takeaway: In this walkthrough, the calculator’s time component continues to scale with days. The practical significance of the 4-year period is which timing rule applies; because this example uses the general default (and does not identify a claim-specific deviation), the boundary is handled using that general-period logic.
