Every payslip in Singapore has a CPF line on it, but most people never actually look at how that number is worked out. Understanding the mechanics matters — it affects your take-home pay, your CPF balances, and eventually your retirement payout. Here’s the breakdown without the jargon.
The basic split: employer and employee
CPF contributions are made up of two parts:
- Employee contribution — deducted directly from your monthly salary.
- Employer contribution — paid on top, by your employer, on your behalf.
Both portions go into your CPF account. The combined rate — employer’s share plus employee’s share — is what people usually mean when they talk about “the CPF rate,” and it’s higher than either party pays alone.
The exact percentages are not flat across the board. They depend primarily on your age, and to a lesser extent on your wage level. CPF rates are reviewed periodically by the government, particularly for older workers, so the exact numbers can change — always cross-check the current rates on the official CPF Board website (cpf.gov.sg) rather than an old screenshot or outdated article, including this one.
Why age matters so much
CPF contribution rates step down in bands as you get older. Workers in their 30s, 40s, and early 50s are typically on the highest combined rate. From around age 55 onwards, both the employee and employer rates gradually decrease in stages, continuing to step down further past age 60, 65, and beyond.
This tiered structure is meant to reflect the reality that take-home cash flow often matters more to older workers, while also easing the cost to employers of hiring older staff. If you’re in your late 50s or 60s and your CPF deduction looks smaller than a younger colleague’s on the same salary, that’s expected — it’s not an error on your payslip.
Ordinary Wage vs Additional Wage
CPF contributions are calculated differently depending on the type of wage:
- Ordinary Wages (OW) — your regular monthly salary. CPF contributions apply up to a monthly OW ceiling, which is reviewed periodically by the government. Any salary above that ceiling in a given month is not subject to CPF contributions.
- Additional Wages (AW) — bonuses, commissions, and other non-monthly payments. CPF on AW is capped using a separate annual formula (the AW ceiling), which factors in how much OW you’ve already earned for the year.
This is why a large annual bonus doesn’t always attract CPF contributions on the full amount — once you hit the AW ceiling for the year, no further CPF is deducted on additional wage payments for that year.
Where the contribution actually goes
Your CPF contribution isn’t a single pot — it’s split across three accounts, each with a different purpose:
- Ordinary Account (OA) — usable for housing, approved investments, insurance, and education. Earns a base interest rate set by CPF, with an extra 1% on the first S$20,000 of combined balances for most members.
- Special Account (SA) — for retirement and CPF-approved investments, earning a higher interest rate than OA.
- MediSave Account (MA) — for healthcare expenses, hospitalisation insurance premiums, and approved medical costs.
The proportion allocated to each account shifts with age too — younger workers typically have a larger share going into OA (useful for a first home), while the split shifts more toward MA and retirement savings as you get older.
What self-employed people should know
If you’re self-employed, there’s no employer contribution — you don’t get the “free” employer half that salaried employees receive. Self-employed CPF contributions are voluntary for the OA and SA, but MediSave contributions are compulsory once your net trade income crosses a set threshold, since MediSave is treated as more of a national requirement than a discretionary retirement top-up.
A quick sanity check on your payslip
If your CPF deduction doesn’t match what you expect:
- Confirm your age band — this is the single biggest factor.
- Check whether the pay includes AW (bonus/commission) versus pure OW — the calculation differs.
- Confirm your salary isn’t above the OW ceiling for that month, which would cap the CPF-eligible portion.
- If you’re a Singapore Citizen or PR of a certain immigration status, note that first- and second-year PRs are on a graduated contribution rate schedule, which is lower than the standard rate.
The bottom line
CPF contribution rates aren’t arbitrary — they follow a defined structure based on age, wage type, and wage level, reviewed periodically by policy. The rates you were quoted last year may not be this year’s rates, especially around the 55+ age bands where changes happen most often. When in doubt, the CPF Board’s official contribution rate tables are the definitive source — this guide is meant to help you understand the mechanics, not replace them.
