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: Market-neutral work and pay planning using your own assumptions.

1. Formulas and units

Total holiday pay
totalHolidayPay = basePayForNotWorkedHours + workedHolidayPay + fixedBonus

Where

fixedBonus
Fixed holiday bonus (currency units)Source: User assumption
totalHolidayPay
Total holiday pay (currency units)Source: Calculated output
workedHolidayPay
Worked holiday pay (currency units)Source: Calculated output
basePayForNotWorkedHours
Pay for hours not worked (currency units)Source: Calculated output
Worked pay
workedHolidayPay = workedHolidayHours × baseHourlyRate × selected rule factor

Where

baseHourlyRate
Base hourly rate (currency units/hour)Source: User assumption
workedHolidayHours
Holiday hours worked (hours)Source: User assumption
factor
Entered factor (factor)Source: User assumption
workedHolidayPay
Worked holiday pay (currency units)Source: Calculated output
Not-worked pay
basePayForNotWorkedHours = notWorkedHolidayHours × baseHourlyRate

Where

baseHourlyRate
Base hourly rate (currency units/hour)Source: User assumption
notWorkedHolidayHours
Paid holiday hours not worked (hours)Source: User assumption
basePayForNotWorkedHours
Pay for hours not worked (currency units)Source: Calculated output
Straight-time comparison
straightTimePay = (notWorkedHolidayHours + workedHolidayHours) × baseHourlyRate

Where

baseHourlyRate
Base hourly rate (currency units/hour)Source: User assumption
notWorkedHolidayHours
Paid holiday hours not worked (hours)Source: User assumption
workedHolidayHours
Holiday hours worked (hours)Source: User assumption
straightTimePay
Straight-time comparison (currency units)Source: Calculated output
Uplift
upliftOverStraightTime = totalHolidayPay − straightTimePay

Where

totalHolidayPay
Total holiday pay (currency units)Source: Calculated output
straightTimePay
Straight-time comparison (currency units)Source: Calculated output
upliftOverStraightTime
Uplift over straight time (currency units)Source: Calculated output

Money inputs and outputs use the currency selected in the scenario without changing the canonical methodology. Pay, time, benefits and work-related costs use the units stated beside each input.

2. Worked example

Input assumptions

Apply a 1.5 total multiplier to six worked hours, plus eight paid hours not worked and a 50 bonus.

Calculation and outputs

Example

Apply a 1.5 total multiplier to six worked hours, plus eight paid hours not worked and a 50 bonus.

Total holiday pay
560.00 currency units
Worked holiday pay
270.00 currency units
Pay for hours not worked
240.00 currency units
Straight-time comparison
420.00 currency units
Uplift over straight time
140.00 currency units

Worked, not-worked, straight-time and uplift amounts remain explicit.

Interpretation

Use the result only for the rule interpretation and factor you entered.

3. Validation and boundary checks

  • Rule type is a closed categorical choice.
  • Hours, rate, factor and bonus are non-negative.
  • Total multiplier and premium addition are calculated differently.

4. Assumptions and source classification

  • Every rule term is entered by the user.
  • A premium addition factor of 0.5 means straight time plus 0.5 times base pay.
  • A total multiplier of 1.5 means 1.5 times base pay.

This calculator has no current policy-data dependency. Its work and pay assumptions are user supplied. Registered family-level regression suites exercise the shared work-logic engine and worked-result reconciliation.

5. Limitations

  • No legal entitlement, public-holiday calendar, employer policy or payroll tax is applied.
  • The tool cannot determine which rule applies.
  • Confirm rule wording and eligibility independently.

This is educational decision support, not personalised tax, legal, financial or career advice. Check the treatment of your circumstances under the rules that apply to you 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. There is no official threshold or benchmark to refresh for this calculator. Work and pay inputs remain user-supplied because they vary by person, job and contract.
