Background
CPF distinguishes between ordinary wages, which are paid for work in the month such as basic salary and fixed allowances, and additional wages, such as annual bonuses and leave encashment. Ordinary wages are capped at S$8,000 a month from January 2026, while additional wages are capped by an annual ceiling of S$102,000 minus the ordinary wages already subject to CPF in the year.
The Employment Act sets out how hourly and daily rates are calculated for overtime, public holiday work and salary deductions. These formulas use the monthly basic rate of pay rather than gross salary, which is why the numbers can look lower than a simple division of your salary by hours worked.
