Calculation formula (reference)

Ordinary hourly wage = monthly base wage ÷ 209 hours (40h/week basis)
Overtime premium = ordinary hourly × 1.5 × overtime hours
Night premium (add-on) = ordinary hourly × 0.5 × night hours
Holiday premium = ordinary hourly × 1.5 × holiday hours
Monthly shortfall = monthly statutory premium − comprehensive wage amount (0 if negative)
Total claimable = monthly shortfall × claim months (max 36)
