Central Provident Fund (CPF)
Concept
The Central Provident Fund (CPF) is Singapore's mandatory social-security savings system covering three pillars: retirement, housing and healthcare. Both employee and employer contribute; the money is split across separate accounts with different purposes and interest rates. Members may invest a portion under the CPF Investment Scheme (CPFIS), and at retirement CPF savings are converted into lifelong income through CPF LIFE.
Key rules & facts
- Four accounts:
- Ordinary Account (OA) — the flexible one: housing, approved insurance, investment and education. Base rate 2.5% (verify current).
- Special Account (SA) — long-term retirement savings; higher floor rate 4% (verify current, and the 2025 SA-closure changes for members aged 55+ whose SA is being restructured).
- MediSave Account (MA) — healthcare and MediShield Life premiums; also earns the higher floor rate (verify).
- Retirement Account (RA) — created at age 55 by transferring OA + SA up to the applicable retirement sum; funds CPF LIFE.
- Extra interest: an extra +1% on the first $60,000 of combined balances, and a further +1% on the first $30,000 for members aged 55+ (verify tiers and caps — these change).
- CPFIS: split into CPFIS-OA and CPFIS-SA investing only in MAS-included/approved products. The SA list is materially more restrictive (e.g. no direct shares or gold). "First-dollar" / percentage limits apply — e.g. shares ≤ 35% and gold ≤ 10% of investible savings (verify current caps and the minimum sums that must stay in OA/SA before investing).
- Retirement sums at 55: Basic (BRS), Full (FRS = 2 × BRS), and Enhanced (ERS). Above the FRS a member may withdraw the excess; setting aside only the BRS requires a property pledge/charge on a Singapore property (verify current dollar figures — these are revised yearly).
- CPF LIFE: a national annuity paying lifelong monthly income out of the RA. Three plans — Standard, Basic, Escalating. Payouts start between age 65 and 70 depending on when the member elects to begin (verify current payout-eligibility age rules).
Key data
| Account | Primary uses | Rate (verify current) | Investable under CPFIS? |
|---|---|---|---|
| OA | Housing, insurance, investment, education | Base 2.5% | Yes — CPFIS-OA (broader list) |
| SA | Retirement savings | Floor 4% | Yes — CPFIS-SA (restricted list) |
| MA | Healthcare, MediShield Life | Floor 4% (verify) | No (healthcare-earmarked) |
| RA | Funds CPF LIFE payouts | Retirement-sum rate (verify) | No |
| Retirement sum (age 55) | Relationship | Note |
|---|---|---|
| BRS | Base tier | Needs a property pledge to set aside only this (verify) |
| FRS | = 2 × BRS | Withdraw amounts above FRS in cash (verify) |
| ERS | Highest tier | Top up for larger CPF LIFE payouts (verify multiple of FRS) |
Exam angle
Recall of account purposes and CPF LIFE mechanics, plus situational questions on whether a CPF-funded investment is permissible (OA list vs the tighter SA list) and on payout logic (which account funds CPF LIFE, when payouts start).
⚠ The trap
Assuming OA and SA share the same investable list — the SA list is much more restrictive (no direct shares/gold). Second trap: confusing the retirement-sum tiers (BRS/FRS/ERS) with the CPF LIFE plan names (Standard/Basic/Escalating) — different concepts.
Worked example
A 40-year-old wants to buy an individual stock using CPF. This is only possible under CPFIS-OA (subject to the ≤35% shares limit and the minimum OA balance rule) — not from the SA, whose approved list excludes direct shares (verify current limits).
Takeaway
OA is flexible; SA is guarded; MA is healthcare; RA + CPF LIFE = lifelong income. All precise rates, caps and sums change yearly — hedge them.
