How CPF Contributions Are Worked Out
Each month, you and your employer each pay a percentage of your wage into your CPF. The percentages depend on your age and, for Permanent Residents, how long you have held that status. The total is rounded to the nearest dollar. Your own share drops the cents, and your employer pays the rest.
Only the first S$8,000 of monthly Ordinary Wages attracts CPF. Lower-paid employees are treated differently: up to $500 a month only the employer pays, and between $500 and $750 the employee's share is phased in.
The contribution is then split. MediSave gets its share first, then the Special Account, or the Retirement Account if you are above 55. The Ordinary Account gets what is left. As you get older, less goes to the Ordinary Account and more to retirement and healthcare.
