Worked example: Wage Backpay in Utah

Example inputs
Below is a worked example showing how DocketMath’s Wage Backpay calculator could model a wage-backpay amount in Utah (US-UT) using a general statute of limitations rule.
Jurisdiction-aware rule used (Utah):
- General SOL period: 4 years
- Utah Code: Utah Code § 76-1-302
- Source (Utah Courts): https://www.utcourts.gov/en/legal-help/legal-help/procedures/statute-limitation.html
Note: For this example, no wage-backpay–specific sub-rule was located. DocketMath therefore uses the general/default 4-year period associated with Utah Code § 76-1-302 rather than a claim-type-specific SOL.
Facts we will plug into the calculator
Assume a worker alleges unpaid wages for a continuous period. For simplicity, we model a steady hourly rate and a consistent number of hours per week.
- State (jurisdiction): Utah (US-UT)
- Pay rate (gross): $20.00/hour
- Hours worked but unpaid: 40 hours/week
- Start of unpaid period: May 1, 2021
- End of unpaid period: December 31, 2022
- Filing date (date suit is commenced): April 15, 2025
- Wage backpay calculation approach: unpaid wages × eligible workweeks (including within SOL lookback)
Derived timing inputs (to connect the SOL to dollars)
The key question in a limitations-driven wage-backpay model is: Which weeks fall within the 4-year lookback from the filing date?
- SOL length: 4 years
- Lookback start date: April 15, 2025 minus 4 years ⇒ April 15, 2021
- Lookback window (inclusive conceptually): from April 15, 2021 through April 15, 2025 (but unpaid work ended earlier in our scenario)
Because the unpaid period runs May 1, 2021 → December 31, 2022, everything unpaid after April 15, 2021 is within the lookback window.
That means, in this specific scenario, the full unpaid period is inside the SOL window.
Example run
You can run the same scenario in DocketMath here: /tools/wage-backpay.
Gentle note: This is a worked example for modeling purposes and should not be treated as legal advice. Actual wage disputes may require more detailed payroll records and could involve additional factual or legal issues.
Step 1: Calculate eligible weeks within the SOL period
Unpaid period:
- From May 1, 2021 through December 31, 2022
Since the SOL lookback starts April 15, 2021, the entire unpaid span is within the 4-year SOL window tied to Utah Code § 76-1-302.
To convert dates into workweeks for a model like this, we assume:
- 40 hours/week
- A week-based count of the interval (typical “worked example” simplification)
Interval length (calendar-based):
- May 1, 2021 → Dec 31, 2022 covers about 86 weeks.
Warning: Real-world wage records are not always perfectly aligned to week boundaries and may include partial weeks, off-cycle pay periods, overtime premiums, or varying schedules. Use DocketMath to reflect your actual payroll pattern rather than relying on a week-approximation if you have detailed records.
Step 2: Compute weekly unpaid wages
- Weekly unpaid wages = 40 hours/week × $20.00/hour
- Weekly unpaid wages = $800/week
Step 3: Compute wage backpay over eligible weeks
- Backpay = $800/week × 86 weeks
- Backpay = $68,800
So under this example configuration, the modeled wage backpay is:
| Input category | Value |
|---|---|
| Wage rate | $20.00/hour |
| Hours/week | 40 |
| Weekly unpaid wages | $800 |
| Eligible weeks (within 4-year lookback) | 86 |
| Modeled wage backpay | $68,800 |
What would change this number inside DocketMath?
Even with the same filing date, backpay changes if any of these inputs change:
- Pay rate ($/hour): scales linearly (doubling the rate doubles backpay)
- Hours per week: scales linearly
- Unpaid start date: can reduce eligible weeks when it falls outside the 4-year window
- Filing date: shifts the 4-year lookback window, potentially bringing older unpaid weeks into (or pushing them out of) eligibility
Sensitivity check
To show how DocketMath’s SOL-driven logic affects the output, here are three quick variations. All scenarios keep the wage inputs identical ($20/hour, 40 hours/week) and adjust only timing.
Common baseline:
- Weekly unpaid wages: $800/week
- Unpaid end date stays December 31, 2022
- Filing date stays April 15 of the indicated year unless otherwise noted
Scenario A: Filing date later (more recent lookback shifts eligibility)
- Filing date: April 15, 2026
- SOL lookback start: April 15, 2022
Unpaid period: May 1, 2021 → Dec 31, 2022
Eligible portion: from April 15, 2022 through Dec 31, 2022 (roughly the last ~36–38 weeks, depending on week counting)
Approximate:
- Eligible weeks: 38
- Backpay: $800 × 38 = $30,400
Effect vs. baseline ($68,800): large decrease because the lookback window no longer includes the earlier 2021 weeks.
Scenario B: Filing date earlier (lookback starts before unpaid period)
- Filing date: April 15, 2023
- SOL lookback start: April 15, 2019
Unpaid period: May 1, 2021 → Dec 31, 2022
Because the lookback start is well before May 1, 2021, everything unpaid is within the 4-year period.
Approximate:
- Eligible weeks: 86
- Backpay: $800 × 86 = $68,800
Effect vs. baseline: likely unchanged in this fact pattern because the unpaid period is fully within the window.
Scenario C: Unpaid start date moved forward (shorter unpaid period)
- Unpaid start date: October 1, 2021 (instead of May 1, 2021)
- Filing date: April 15, 2025
Now the unpaid period is shorter:
- October 1, 2021 → Dec 31, 2022 ≈ 62 weeks (approx.)
Backpay:
- $800 × 62 = $49,600
Effect vs. baseline: decreases because fewer workweeks are included, not because the SOL cutoff removes any portion.
Quick comparison table
| Scenario | Filing date | Unpaid start | Eligible weeks (approx.) | Modeled backpay |
|---|---|---|---|---|
| Baseline | 4/15/2025 | 5/1/2021 | 86 | $68,800 |
| A (later filing) | 4/15/2026 | 5/1/2021 | 38 | $30,400 |
| B (earlier filing) | 4/15/2023 | 5/1/2021 | 86 | $68,800 |
| C (later unpaid start) | 4/15/2025 | 10/1/2021 | 62 | $49,600 |
Pitfall: SOL math can be deceptively “binary” in worked examples. In real wage disputes, weekly vs. daily accrual, partial weeks, and changes in pay rate can shift the eligible week count enough to matter—especially when the unpaid period starts near the lookback boundary (here, around April 15, 2021 for the 4/15/2025 filing date).
