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.

Payslips must be itemised, showing basic pay, allowances, overtime, deductions and CPF. Comparing a payslip against an independent calculation is the easiest way to catch mistakes, especially in the first month of a new job, after a pay rise, or when you cross an age band.

The Central Provident Fund is Singapore's mandatory savings scheme for citizens and permanent residents. Contributions are shared between employee and employer and flow into the Ordinary Account for housing, education and investment, the Special Account for retirement, and MediSave for healthcare. Because the money is locked up for specific purposes, many people underestimate how much of their total pay it represents.
