Educational only: Work and pay decision support, not tax, legal, financial or career advice.

Privacy: Calculations run locally; Wage101 does not receive your work or pay inputs.

Update policy: Reviewed when formulas or official dependencies change.

Scope: US work and pay planning using your own assumptions.

1. Formulas and units

Gross pay for this workday
grossDayPay = regularPay + timeAndHalfPay + doubleTimePay

Where

grossDayPay
Gross pay for this workday (USD/workday)Source: Calculated output
Regular pay
regularPay = min(hoursInWorkday, 8) × regularHourlyRate

Where

regularHourlyRate
Regular hourly rate (USD/hour)Source: User assumption
hoursInWorkday
Hours in this one workday (hours/workday)Source: User assumption
regularPay
Regular pay (USD/workday)Source: Calculated output
Time-and-a-half pay
timeAndHalfPay = min(max(hoursInWorkday − 8, 0), 4) × regularHourlyRate × 1.5

Where

regularHourlyRate
Regular hourly rate (USD/hour)Source: User assumption
hoursInWorkday
Hours in this one workday (hours/workday)Source: User assumption
timeAndHalfPay
Time-and-a-half pay (USD/workday)Source: Calculated output
Double-time pay
doubleTimePay = max(hoursInWorkday − 12, 0) × regularHourlyRate × 2

Where

regularHourlyRate
Regular hourly rate (USD/hour)Source: User assumption
hoursInWorkday
Hours in this one workday (hours/workday)Source: User assumption
doubleTimePay
Double-time pay (USD/workday)Source: Calculated output
Double-time hours
doubleTimeHours = max(hoursInWorkday − 12, 0)

Where

hoursInWorkday
Hours in this one workday (hours/workday)Source: User assumption
doubleTimeHours
Double-time hours (hours/workday)Source: Calculated output

Money inputs and outputs use USD. Pay, time, benefits and work-related costs use the units stated beside each input.

2. Worked example

Input assumptions

A confirmed nonexempt worker earns $20 per hour and works a 10-hour workday.

Calculation and outputs

Example

A confirmed nonexempt worker earns $20 per hour and works a 10-hour workday.

Gross pay for this workday
220.00 currency units
Regular pay
160.00 currency units
Time-and-a-half pay
60.00 currency units
Double-time pay
0.00 currency units
Double-time hours
0

Regular, time-and-a-half and double-time hours and pay remain separate for one workday.

Interpretation

Use the result only for one confirmed ordinary California workday; it is not a weekly overtime calculation.

3. Validation and boundary checks

  • The worked example uses the same shared-work-logic engine as the interactive planner.
  • Unsupported eligibility, policy branches and out-of-range assumptions fail closed.
  • Result cards, trace, CSV, PDF and methodology bind to named engine result fields.

4. Assumptions and source classification

  • General California nonexempt coverage and an ordinary workday have been confirmed.
  • The entered regular hourly rate is the correct legal regular rate for this workday.

Official dependencies used by this calculator are captured in the Wage101 evidence register and version-acknowledged in this page history. User-entered work and pay assumptions remain separate from those official inputs.

5. Limitations

  • Weekly overtime, seventh-day rules and work across multiple days are excluded.
  • Alternative workweeks, exemptions, collective agreements and industry-specific rules are excluded.

This is educational decision support, not personalised tax, legal, financial or career advice. Check how the rules that apply in United States treat your work and pay circumstances, and seek qualified advice where appropriate.

6. Update and evidence policy

Registered family-level suites test formula invariants and example reconciliation; the release ledger records that coverage without claiming a separate oracle for every line of public copy. Registered official sources block dependent public workflows when their evidence or version acknowledgement is unavailable or invalid. Work and pay inputs remain user-supplied because they vary by person, job and contract.
