Example inputs

Run this scenario in DocketMath using the Damages Allocation calculator.

This worked example shows how DocketMath can allocate damages using a jurisdiction-aware baseline for Illinois. We’ll focus on selecting the correct statute of limitations (SOL) lookback window, then applying it to an illustrative damages timeline.

Note: This is a practical walkthrough of calculations and assumptions—not legal advice. Real cases may involve additional, claim-specific rules that aren’t covered by this general example.

What DocketMath needs (for this calculator)

Inputs for a typical damages-allocation run include:

Jurisdiction: Illinois (US-IL)
Date the claim accrued (start point for SOL lookback)
Date suit was filed
Damages timeline (a list of dated amounts, e.g., payments, losses, or categories that accrue over time)
Allocation method: allocate “covered vs. time-barred” portions based on the SOL window
Default SOL period: 5 years (Illinois general SOL)

Illinois SOL rule used in this example (general/default)

Illinois’s general/default SOL period is 5 years under 720 ILCS 5/3-6. The jurisdiction data provided here uses that general period, and no claim-type-specific sub-rule was found for this demonstration.

General SOL Period: 5 years
General Statute: 720 ILCS 5/3-6

Concrete inputs for the run

Assume the following:

Jurisdiction: US-IL (Illinois)
Accrual date: January 15, 2020
Suit filed: January 20, 2025
SOL period: 5 years (general default)
Therefore, the covered window runs from January 15, 2020 through January 15, 2025 in this example.

Now consider damages that accrue in these dated chunks:

Segment	Date accrued	Description	Amount
1	2019-12-20	Early loss period	$12,000
2	2020-03-01	Losses within window	$5,500
3	2021-07-10	Losses within window	$9,250
4	2024-11-30	Losses within window	$7,800
5	2025-01-16	Late loss (just after window cutoff)	$3,600

These segments intentionally straddle the SOL boundary so you can see allocation change.

Example run

Below is the worked allocation logic you’d apply via DocketMath for an SOL-based covered vs. time-barred split using Illinois’s general 5-year SOL from 720 ILCS 5/3-6.

Run the Damages Allocation 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: Compute the SOL cutoff date

Accrual date: 2020-01-15
General SOL period: 5 years
Cutoff (end of covered period): 2025-01-15

Interpretation for allocation in this example:

Accrued on/before 2025-01-15 → covered
Accrued after 2025-01-15 → time-barred (for this general SOL test)

Step 2: Classify each damages segment

Segment	Date accrued	Covered vs. time-barred	Amount
1	2019-12-20	Before 2020-01-15 → time-barred	$12,000
2	2020-03-01	Between 2020-01-15 and 2025-01-15 → covered	$5,500
3	2021-07-10	Within window → covered	$9,250
4	2024-11-30	Within window → covered	$7,800
5	2025-01-16	After 2025-01-15 → time-barred	$3,600

Step 3: Totals

Covered damages total = $5,500 + $9,250 + $7,800 = $22,550
Time-barred damages total = $12,000 + $3,600 = $15,600
Gross total = $22,550 + $15,600 = $38,150

How DocketMath presents the output (what to look for)

Using DocketMath’s damages-allocation tool (/tools/damages-allocation), you’d typically look for:

SOL cutoff date (computed from accrual + 5 years under 720 ILCS 5/3-6)
Covered damages and time-barred damages
Potentially a segment-by-segment allocation table, depending on how the tool formats results

Warning: This example uses the general/default SOL period from 720 ILCS 5/3-6 because no claim-type-specific sub-rule was found in the provided jurisdiction data. If a specific Illinois claim type has a different SOL, the allocation window—and therefore totals—can change materially.

Sensitivity check

Small changes to timing can swing allocations, especially when damages straddle the cutoff date. Here are three targeted adjustments and the resulting allocation impact under the same general Illinois rule (5 years, 720 ILCS 5/3-6).

To test sensitivity, change one high-impact input (like the rate, start date, or cap) and rerun the calculation. Compare the outputs side by side so you can see how small input shifts affect the result.

Sensitivity 1: Filing date pushed 10 days later

Change only “suit filed” from 2025-01-20 to 2025-01-30.

Under a simple allocation approach keyed to accrual + SOL, the cutoff remains 2025-01-15.
The classification of segments stays the same.

Result:

Covered = $22,550
Time-barred = $15,600

Takeaway: In many SOL allocation calculators, “filing date” may matter for some eligibility presentations, but the window end often remains tied to accrual + SOL unless the tool explicitly uses filing date as the boundary.

Sensitivity 2: Accrual date moved 30 days earlier

Move accrual from 2020-01-15 to 2019-12-16.

New cutoff:

2019-12-16 + 5 years = 2024-12-16

Reclassify segments:

Segment 4 (2024-11-30) stays covered.
Segment 5 (2025-01-16) remains time-barred.
Segment 1 (2019-12-20) becomes covered because it is now after 2019-12-16.

New result:

Covered damages = $12,000 + $5,500 + $9,250 + $7,800 = $34,550
Time-barred damages = $3,600
Gross total remains $38,150

Takeaway: Accrual date selection is often the biggest driver. A 30-day shift moved Segment 1 from time-barred to covered.

Sensitivity 3: Late loss date changed across the cutoff by 1 day

Keep accrual at 2020-01-15, cutoff at 2025-01-15, and change Segment 5 from:

2025-01-16 ($3,600) to 2025-01-15 ($3,600)

Then Segment 5 becomes covered (on the cutoff date).
