The CPF account earmarked for retirement income. Earns 4% guaranteed (with an extra 1% on first S$60,000 combined). Funds are merged into your Retirement Account at age 55.
The Special Account is earmarked specifically for retirement. It earns 4% guaranteed (with an extra 1% on the first S$60,000 combined balance), making it one of the most attractive risk-free returns available to Singapore residents.
On your 55th birthday, your SA balance is transferred into your Retirement Account up to the Full Retirement Sum. Any remaining SA balance stays in SA and continues to earn 4%.
For employees under 35, ~16% of each month's CPF contribution goes into SA. The share grows with age — by 50, SA receives ~37% of contributions.
This age-graded allocation reflects the design intent: when you're young and need housing, OA gets the larger share. When you're closer to retirement, more is funnelled into SA.
Voluntary cash top-ups via RSTU: up to S$8,000 / year for tax relief, with the same amount available for family-member top-ups. These contribute directly to SA before age 55.
OA → SA transfer: irreversible, but instantly upgrades 2.5% to 4%. Best done in your 30s and 40s while OA isn't fully committed to housing.
Don't invest SA via CPFIS-SA: the bar for investment success is the 4% guaranteed rate. Few funds beat that net of fees. SA is the safe-anchor account — leave it earning 4%.
Hitting the FRS in SA early (sometimes called 1M55 — million-by-55 — though the FRS is far less than a million) is a popular goal among financially-disciplined Singaporeans.
The math: starting at age 30, you'd need to top up ~S$5,000/year on top of your standard contributions to reach FRS by 55, assuming average wage growth and full CPF participation.
From 1 January 2025, the SA closes for those aged 55 and above — its balance flows entirely into the Retirement Account up to FRS / ERS, and the rest into OA. Plan SA top-ups accordingly while you're still eligible.
The CPF account earmarked for retirement. Earns 4% guaranteed (with an extra 1% on the first S$60,000 combined balance). Funds flow into your Retirement Account at age 55 up to your chosen Retirement Sum.
Technically yes via CPFIS-SA on approved unit trusts and ETFs, but the bar is the 4% guaranteed rate. Few funds beat that net of fees consistently — most planners advise leaving SA alone and letting it compound at 4%.
Your SA balance is swept into the new Retirement Account up to your applicable Retirement Sum. Any remainder used to stay in SA, but from 1 January 2025, the SA closes for those above 55 — surplus above FRS/ERS flows into OA.
Yes if you can afford it. The 4% guaranteed return + RSTU tax relief (up to S$8,000/year) is one of the most efficient long-term savings moves in Singapore — provided you're comfortable with the lock-in until 55+.
