Inputs you will need

Run this scenario in DocketMath using the Wage Backpay calculator.

To run wage backpay calculations in New Mexico (US-NM) with DocketMath, gather a small set of concrete inputs first. This keeps the calculation auditable and helps you avoid common “missing data” problems that can change the result.

Because DocketMath applies jurisdiction-aware defaults, the statute of limitations (SOL) setting affects what date range you should enter. For New Mexico, the applicable default SOL period for wage backpay–style calculations is:

  • 2 years under N.M. Stat. Ann. § 31-1-8
    • Important: DocketMath uses this general/default period because no claim-type-specific sub-rule was found in the jurisdiction data provided. In plain terms, treat 2 years as your default unless you have reason to use a different, more specific rule.

Before you open the calculator, collect these inputs (even if you start with estimates):

  • Work location / jurisdiction confirmation
    • Confirm the work was performed in New Mexico (US-NM).
  • Pay period schedule
    • The pay frequency (e.g., weekly, biweekly, semimonthly, monthly).
    • Any known “off-cycle” payments (bonus checks or special payments).
  • Backpay start date
    • The date the underpayment began (or the first day of the period you’re claiming).
  • Backpay end date
    • The date the underpayment ended (or the last day of the period you’re claiming).
  • Regular rate inputs
    • The hourly wage (or base pay rate) that should have applied.
    • If your wage changed during the period, you typically have two practical options:
      • run separate segments for each rate period, or
      • use the wage that applies to the largest portion of the timeframe you enter (less precise, but can work for a rough estimate).
  • Hours information
    • Total hours actually worked during the claimed period (or hours per pay period, if you have them).
    • Overtime hours, if applicable (for example, hours above a workweek threshold—use your pay setup that matches your records/tool inputs).
  • Payments received
    • Total amount you were paid during the claimed period, or itemized pay totals by pay date.
  • ☐ **Deductions / offsets (if applicable)
    • Any amounts you believe should be netted against backpay (for example, if the employer already paid a portion for the claimed hours).
  • ☐ **Documentation references (recommended)
    • Payroll stubs, timesheets, offer letter / wage notice, and any written communications about pay.

If you’re working with limited records, start with a minimum viable dataset: dates, wage rate, hours, and payments received. DocketMath can still be helpful, but missing or incorrect hours/pay changes will shift the output.

Pitfall to watch: Entering a backpay range outside the 2-year default SOL under N.M. Stat. Ann. § 31-1-8 can overstate the likely recoverable period. Use the SOL-adjusted window when you can.

Where to find each input

Use the following sources to locate the specific numbers DocketMath needs:

  • Work location / jurisdiction
    • Employment offer letter, onboarding paperwork, or pay-related documents showing worksite location.
  • Pay period schedule
    • Payroll stubs (look for “Pay Period” dates) and employer payroll policy documentation (if available).
  • Backpay start and end dates
    • Payroll stubs and timesheets:
      • Start date often corresponds to the first pay period reflecting the underpayment.
      • End date often corresponds to the last pay period where the correct wage is paid.
  • Regular hourly wage / base rate
    • Offer letter, wage notice, or the rate shown on payroll stubs.
    • If wages changed, look for effective-date details in HR messages or pay-stub history.
  • Hours worked
    • Timesheets, scheduling apps, or payroll stubs with hours by pay period.
    • If you only have totals, enter the total hours for the period you’re claiming.
  • Payments received
    • Pay stubs showing gross pay and pay dates.
    • If net pay is all you have, note that backpay calculations usually align more closely with gross wages—so if you use totals, try to use the gross-based totals reflected in your stubs.
  • Deductions / offsets
    • Payroll stubs list items such as taxes and benefits (typical payroll deductions).
    • Offsets for backpay should generally reflect wages already paid for the claimed period—not ordinary statutory deductions—so be careful to net only what corresponds to wages under the same time period.

Quick readiness checklist:

Run it

After you’ve collected your inputs, run the calculation in DocketMath’s wage-backpay tool here: /tools/wage-backpay

Enter the inputs in DocketMath and run the Wage Backpay calculation to generate a clean breakdown: Run the calculator.

Step-by-step inputs to enter (US-NM)

  1. Confirm New Mexico jurisdiction
    • Set US-NM in the tool (or confirm the tool is using the correct jurisdiction).
  2. Enter the claimed date range
    • Add your backpay start date and backpay end date.
  3. Apply the default SOL window
    • DocketMath is guided by the general SOL period for New Mexico: 2 years under N.M. Stat. Ann. § 31-1-8.
    • Because no claim-type-specific sub-rule was found in the provided ruleset, treat this 2-year period as the default.
  4. Add wage rate and hours
    • Enter the regular hourly wage.
    • Provide hours for the timeframe:
      • total hours for the whole period, or
      • hours per pay period (depending on the workflow the tool supports).
    • If overtime is part of your model, include overtime-related inputs if the tool offers them and your records support the values.
  5. Enter payments received
    • Provide the total wages paid during the claimed period (or per-pay-period totals, if that workflow fits your records).
  6. Review the outputs
    • DocketMath will generally compute:
      • what you should have been paid based on your wage rate and hours, then
      • the difference versus what you received, applying any netting/offsets as indicated by your inputs.

How changing an input typically affects the result

Input you changeLikely effect on output
Backpay start date moves forwardReduces the total claimed period → lower backpay estimate
Backpay end date moves forwardIncreases the period → higher estimate
Regular hourly wage increasesIncreases “should have been paid” → higher potential backpay
Hours worked increaseIncreases wages due → higher potential backpay
Payments received increaseReduces the remaining difference → lower backpay estimate
Overtime hours added (if applicable)Increases wages due if your tool model includes overtime

Warning: SOL mechanics can materially affect the recoverable window. The New Mexico default is 2 years under N.M. Stat. Ann. § 31-1-8, and DocketMath treats it as the default because no claim-type-specific sub-rule was found in the provided jurisdiction data.

After you run it, save your inputs and outputs. If you discover a wage change midstream, re-run using segmented date ranges/rates if the tool supports it (or approximate using the rate that most closely matches each sub-period).

Gentle note: This walkthrough is for calculating and organizing information, not legal advice. If your situation may involve a different SOL rule or unique wage/off-setting facts, consider getting guidance from a qualified professional.
