How the CPF SA Interest Rate Is Set

The CPF SA interest rate is based on: 80% of 12-month fixed deposit rate + 20% savings deposit rate of major local banks, subject to a statutory minimum floor of 4% per annum introduced on 1 January 1999. In practice, Singapore deposit rates have generally been below 4%, making the floor the operative rate. An extra 1% is earned on the first S0,000 of combined CPF balances (capped at S0,000 from OA), effectively giving SA up to S0,000 an enhanced 5% return.

CPF SA Interest Rate History: Key Milestones

Pre-1999: SA rates were higher (5–6.5%) during the high-interest 1980s and early 1990s. January 1999: 4% statutory floor introduced for SA and MA; 2.5% floor for OA. 2007–2008: Extra 1% on first S0,000 combined CPF balances introduced. 2023–2024: Rising market rates briefly made the formula exceed 4%; rates normalised back. January 2025: CPF SA closed for members under 55 — balances transferred to OA and MA.

Impact of SA Closure on Future Interest Rates

Members under 55 (post-closure): SA balances shifted to OA (2.5% p.a.) and MA (4% p.a.) — the high-interest 4% benefit from SA is largely lost for younger members. Members at 55+: Retirement Account continues to earn 4% floor — equivalent to old SA. SA Shielding (OA-to-SA transfer strategy to preserve SA during FRS top-up) is now moot as SA no longer exists for those under 55.

Maximising CPF Returns in the Post-SA World (2026)

For members under 55: (1) Top up MA to Basic Healthcare Sum (S1,500) to maximise 4% earning pool. (2) Invest OA via CPFIS in low-cost ETFs if you can beat 2.5% net of fees. (3) Use SRS (S5,300/year) as your high-growth tax-advantaged retirement vehicle — invest in STI ETF, S-REIT ETF, or dividend stocks. (4) At 55, top up RA via RSTU to earn 4% and qualify for tax relief.

What is the CPF Special Account interest rate in Singapore?
The CPF SA historically earned 4% per annum, subject to a statutory minimum floor introduced in 1999. An extra 1% is earned on the first S0,000 of combined CPF balances.
Why was the CPF Special Account closed in 2025?
The CPF SA for members under 55 was closed on 19 January 2025, as announced in Budget 2024. Balances were transferred to OA and MA. The RA at 55+ continues to provide 4% p.a. for retirement savings.
What happens to my CPF SA balance after the SA closure?
For members under 55, SA balances were reallocated to OA (2.5%) and MA (4%) according to age-based allocation rates. For members at 55+, SA balances transferred to the Retirement Account, which earns the same 4% floor rate.
Does the CPF Retirement Account earn the same interest as the old SA?
Yes. The RA earns the same 4% p.a. floor rate as the old SA, plus the extra 1% on the first S0,000 of combined CPF balances.
How can I maximise CPF returns now that the SA is closed?
Top MA to Basic Healthcare Sum (S1,500) for 4% returns; invest OA via CPFIS if you can beat 2.5%; use SRS (S5,300/year) as your high-growth retirement vehicle; top up RA via RSTU at 55+ for 4% and tax relief.
