Worked example: Wage Backpay in New Mexico

Example inputs

This worked example shows how DocketMath can estimate wage backpay timeframes and amounts in New Mexico (US-NM) using the jurisdiction-aware general statute of limitations (SOL).

Because the brief you provided did not identify a claim-type-specific wage backpay SOL rule, this example uses the general/default SOL period for New Mexico:

  • General SOL period: 2 years
  • General statute: N.M. Stat. Ann. § 31-1-8

Note: If your situation involves a specific statutory wage claim with a different limitations rule, the results below may not match that claim’s governing SOL. DocketMath’s jurisdiction rules here reflect the general/default period because no claim-type-specific sub-rule was found.

Scenario (what we’re modeling)

Assume an employee alleges unpaid wages for the following dates:

  • Last day worked before the wage shortfall stopped: 2026-02-15
  • Filing date (when the claim is brought): 2026-03-01
  • Hourly wage rate: $22.50
  • Hours unpaid per week: 12
  • Work schedule stability: weekly hours are consistent (12 hours each week)
  • Start of unpaid wages (for modeling): 2025-10-01
  • End of unpaid wages: 2026-02-15

How to think about “SOL lookback” in this example

Under a 2-year general SOL (N.M. Stat. Ann. § 31-1-8), the portion of unpaid wages typically counted for backpay analysis is the period that falls within the 2 years immediately preceding filing—unless a different rule applies.

So the relevant window is:

  • Filing date: 2026-03-01
  • 2-year lookback start: 2024-03-01
  • Unpaid wages in our scenario: 2025-10-01 to 2026-02-15

Because the alleged unpaid wages all occur within 2024-03-01 through 2026-03-01, the SOL lookback does not reduce the start date in this example. That’s a key driver of the output.

Inputs checklist (map these into DocketMath)

  • Jurisdiction: **New Mexico (US-NM)
  • SOL period used: 2 years (N.M. Stat. Ann. § 31-1-8), general/default
  • Filing date: 2026-03-01
  • Unpaid wage start date: 2025-10-01
  • Unpaid wage end date: 2026-02-15
  • Hourly wage: $22.50
  • Weekly unpaid hours: 12

Example run

Here’s the wage backpay calculation as DocketMath would conceptually apply it for US-NM, using the general 2-year SOL from N.M. Stat. Ann. § 31-1-8.

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: Determine the SOL-eligible date range

  • SOL lookback window (general): 2 years before filing
    • From 2024-03-01 to 2026-03-01
  • Alleged unpaid wage range:
    • From 2025-10-01 to 2026-02-15

Since 2025-10-01 is after 2024-03-01, the full alleged range is eligible under the general SOL in this modeled scenario.

SOL-adjusted backpay dates:

  • Start: 2025-10-01
  • End: 2026-02-15

Step 2: Convert eligible time into unpaid work weeks

The time from 2025-10-01 to 2026-02-15 spans roughly 19 weeks when modeled as consistent weekly blocks.

  • Eligible unpaid weeks (modeled): 19

Warning: The number of “weeks” depends on whether you align to payroll periods, weekly schedules, or specific date-by-date hours. In this example, the weekly-hours assumption is doing a lot of work.

Step 3: Multiply hours by wage rate

Now compute unpaid wages:

  • Weekly unpaid hours: 12
  • Wage rate: $22.50/hour
  • Eligible weeks: 19

[ \text{Backpay} = 12 \times 19 \times 22.50 ]

[ = 228 \times 22.50 = 5{,}130.00 ]

Step 4: Report the DocketMath-style output

Using the above inputs, the wage backpay estimate is:

Input / ResultValue
JurisdictionNew Mexico (US-NM)
SOL rule appliedGeneral/default: 2 years (N.M. Stat. Ann. § 31-1-8)
Filing date2026-03-01

SOL-eligible end2026-02-15
Eligible weeks (modeled)19
Weekly unpaid hours12
Hourly wage$22.50
Estimated wage backpay$5,130.00

Sensitivity check

Change one input at a time to see how fast the SOL rule can swing the result. Below, the wage rate and weekly hours remain constant unless otherwise stated.

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 A: Filing date shifts earlier (truncation risk)

Keep unpaid wages the same (2025-10-01 to 2026-02-15), but move the filing date earlier.

  • Hypothetical new filing date: 2025-12-15
  • New SOL lookback window (general): 2023-12-15 to 2025-12-15
  • Eligible unpaid start becomes 2025-10-01 (still eligible)
  • Eligible unpaid end becomes 2025-12-15 (truncates the portion after 12/15)

Approximate effect:

  • If the eligible period shrinks from ~19 weeks to ~10 weeks, backpay drops proportionally.

[ \text{Backpay} \approx 12 \times 10 \times 22.50 = 2{,}700.00 ]

Estimated impact: roughly $5,130 → $2,700 (about a 47% reduction in this rough week-block model).

Pitfall: Many people assume a “2-year SOL” means the entire wage period is always recoverable. The date of filing determines where the cut line falls, and backpay commonly gets truncated if you file too late or too early relative to the unpaid period.

Sensitivity B: Unpaid wage start moves outside the lookback window

Now keep the filing date fixed at 2026-03-01, but move the alleged unpaid start earlier.

  • Original: unpaid start 2025-10-01 ✅ eligible
  • New: unpaid start 2024-02-01 ❌ outside the 2-year lookback (which starts 2024-03-01)

Under N.M. Stat. Ann. § 31-1-8 (general 2-year SOL):

  • SOL-eligible start becomes 2024-03-01
  • SOL-eligible end remains 2026-02-15

This increases eligibility. But the amount added depends on the number of extra eligible weeks and whether the weekly-hours assumption truly matches the work history.

A rough estimate using week-block thinking:

  • Extra time: from 2024-03-01 to 2025-10-01 ≈ 59 weeks (broad counting)

If DocketMath uses weekly blocks, and you truly had 12 unpaid hours per week during the additional period:

[ \Delta \text{Backpay} \approx 12 \times 59 \times 22.50 \approx 15{,}957.00 ]

Key takeaway: SOL can be the difference between a claim covering only recent months vs. spanning more than a year of additional wages—depending on the filing date and alleged unpaid start.

Sensitivity C: Weekly hours and wage rate are linear drivers

Unlike SOL truncation, hours and wage rate changes are typically linear:

  • If weekly hours go from 12 → 10:

    • backpay becomes: [ 10 \times 19 \times 22.50 = 4{,}275.00 ]
    • change: -$855.00
  • If hourly wage goes from $22.50 → $25.00:

    • backpay becomes: [ 12 \times 19 \times 25.00 = 5{,}700.00 ]
    • change: +$570.00
