Example inputs
Run this scenario in DocketMath using the Wage Backpay calculator.
This worked example shows how to use DocketMath’s wage-backpay calculator for Indiana (US-IN) using the general wage-backpay lookback period. You can open the calculator here: /tools/wage-backpay.
Indiana’s general statute of limitations for actions “for which no other period is prescribed” is 5 years, under Indiana Code § 35-41-4-2 (see source link below). In this example, no claim-type-specific sub-rule was found, so we apply the default/general 5-year period rather than a specialized shorter/longer lookback.
Note: This example demonstrates the calculator workflow and the math behind the lookback period. It does not determine legal eligibility or the precise limitations rule that might apply to a specific wage theory or fact pattern.

Scenario (invented for demonstration)
Assume a terminated employee claims wage backpay for time worked but not paid.
You have:
- Backpay start date: January 15, 2020
- Backpay end date: March 20, 2025
- Filing/claim date used for lookback: March 20, 2025
- Hourly rate: $22.50
- Work schedule: 8 hours/day, 5 days/week
- Paid/unpaid window: backpay applies to the period where wages were unpaid
- No additional offsets inputs provided (for example, no interim earnings are entered in this run)
How the calculator treats dates (practical rule)
DocketMath’s wage-backpay calculator uses the lookback limit derived from Indiana’s 5-year general SOL:
- Indiana Code § 35-41-4-2: 5 years for actions where no other period is prescribed.
So the calculator will generally:
- Determine the earliest date allowed by the lookback (filing date minus 5 years).
- Compute unpaid hours between the later of (a) your backpay start date and (b) the lookback earliest date, through your backpay end date (as provided).
Inputs checklist
- Jurisdiction: **Indiana (US-IN)
- General SOL lookback used: 5 years (default/general rule)
- Backpay start date: 2020-01-15
- Backpay end date: 2025-03-20
- Claim date / filing date: 2025-03-20
- Rate: $22.50/hour
- Hours per workday: 8
- Workdays per week: 5
- Offsets: none entered
Example run
Run the Wage Backpay 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 lookback window (Indiana default/general SOL)
Using Indiana Code § 35-41-4-2 (5-year period):
- Filing/claim date: March 20, 2025
- Lookback earliest date (approx.): March 20, 2020
(Calculated as filing date minus 5 years.)
Your provided backpay start date is January 15, 2020, which is earlier than March 20, 2020. That means the calculator will exclude backpay prior to March 20, 2020 and include only wages from March 20, 2020 onward.
So the effective backpay period becomes:
- Effective start (limited by SOL): March 20, 2020
- End: March 20, 2025
Step 2: Estimate payable work hours
Given:
- 8 hours/day
- 5 days/week
That’s 40 hours/week.
Now, the calculator counts workdays/hours in the effective window based on its standard schedule assumptions (5 days per week). Because the window begins and ends on specific calendar dates, exact workday counts can depend on how the tool maps those dates to workdays (for example, partial weeks and the calendar alignment).
To keep the mechanics transparent, we’ll first approximate and then treat the result as an estimate consistent with what the tool is designed to compute:
- March 20, 2020 → March 20, 2025 ≈ 5 years
- Approx weeks in 5 years: 5 × 52 = 260 weeks
- Approx hours: 260 weeks × 40 hours/week = 10,400 hours
Step 3: Multiply by the wage rate
- Hourly rate: $22.50
- Approx wage backpay: 10,400 hours × $22.50/hour
= $234,000
Step 4: What you should expect DocketMath to output
In the calculator, you would submit those inputs and receive, at minimum:
- A SOL-limited earliest date (reflecting the Indiana 5-year general SOL limit from IC § 35-41-4-2)
- Total counted hours
- Total wage backpay (hours × rate)
- Any additional line items included by the tool (such as offset handling or rounding logic, if applicable to your configuration)
For this example, the “shape” of the output should look like this (approximate):
| Output component | Value (approx.) | Why it happens |
|---|---|---|
| SOL-limited earliest date | 2020-03-20 | Indiana general SOL of 5 years under IC § 35-41-4-2 |
| Effective payable window | 2020-03-20 → 2025-03-20 | Excludes wages before lookback start |
| Hours counted | ~10,400 | 40 hours/week × ~260 weeks (calendar alignment may change this slightly) |
| Hourly rate | $22.50 | From inputs |
| Wage backpay estimate | ~$234,000 | Hours × rate |
Warning: If your actual schedule differs (fewer days/week, overtime, shift variations, unpaid holidays), the counted hours—and therefore the total backpay—will change materially. The SOL date limit controls which dates qualify, while the schedule controls how much money those dates represent.
Sensitivity check
This section shows how outputs change when you adjust inputs that affect the calculation.
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.
1) Change the filing date (moves the lookback window)
Because Indiana’s default/general period is 5 years under IC § 35-41-4-2, the filing date directly shifts the earliest includable date.
Assume everything else stays the same:
- Backpay end date stays 2025-03-20
- Backpay start date stays 2020-01-15
- Rate and schedule stay the same
Now compare two filing dates:
- Filing date A: 2025-03-20 → lookback earliest ≈ 2020-03-20
- Filing date B: 2024-03-20 → lookback earliest ≈ 2019-03-20
Because your backpay start is 2020-01-15:
- If the lookback earliest date moves earlier than 2020-01-15, then the calculator will generally include the full provided start-to-end window.
- If it moves after 2020-01-15, then the calculator will exclude that earlier portion.
Practical takeaway: Later filing dates often reduce the included window; earlier filing dates can expand it.
2) Change the backpay end date (adds/removes workdays)
If you extend the backpay end date, the tool counts additional work time—as long as it falls within the SOL-limited window (i.e., after the effective start date determined by the filing date).
Example: extend the end date from 2025-03-20 to 2025-06-20. Since this is after the effective start date (2020-03-20), additional unpaid workdays would increase:
- Hours counted
- Estimated wage backpay
3) Change hourly rate (linear effect)
In a wage-only calculation, wage backpay typically scales directly with the hourly rate (holding hours constant).
If rate increases from $22.50 to $25.00:
- New backpay ≈ old backpay × (25.00 / 22.50)
- That’s an increase of about +11.11%
4) Change work schedule (hours per week changes)
Hours drive the outcome. If your schedule changes from 5 days/week to 4 days/week:
- Hours/week changes from 40 to 32
- Total hours (and wage backpay) drop by 20% (proportional)
Quick comparison table:
| Input change | Expected direction | Expected magnitude (approx.) |
|---|---|---|
| Filing date later by 1 year | Often reduces included time | Depends on where the lookback earliest date lands vs. 2020-01-15 |
| Backpay end date later | Increases included time | Proportional to added hours |
| Rate increases | Increases total backpay | Linear (proportional) |
| Days/week decreases | Decreases hours | Proportional to schedule |
Pitfall: A wage-backpay number can look precise while still depending heavily on two assumptions: (1) how the tool maps the date range to workdays/hours, and (2) whether any offsets/mitigation inputs are included. Even with correct SOL cutoffs, hour-counting assumptions can dominate the final figure.
