Calculate base pay first
- Total working hours × gross hourly wage = base pay.
- Each allowance is then calculated separately and added.
Formula for each allowance
- Eligible hours × hourly wage × rate = allowance amount.
- Example: 40 night hours × €20 × 25% = €200 night allowance.
Overlapping hours
- An hour can be both a night and Sunday hour.
- Whether both allowances are payable depends on applicable rules rather than the arithmetic.
Gross is not net
- The calculator adds gross amounts.
- Tax exemptions, contributions and contractual rules are not assessed automatically.
