CPF Ordinary Account Uses Singapore
Singapore Investor’s Guide 2026 · Not financial advice
The CPF Ordinary Account (OA) in Singapore can be used for housing (HDB and private property purchases), approved investments via CPFIS, education, and certain insurance premiums, earning a base interest rate of 2.5% per annum. This is for informational purposes only and does not constitute financial advice.
What Is the CPF Ordinary Account?
The CPF Ordinary Account (OA) is one of three main CPF accounts (alongside the MediSave Account and Special Account/Retirement Account). As at 2026, employees below 55 contribute 23% of their monthly wages to CPF — of which a portion goes to the OA, based on their age bracket.
OA allocation rates (% of total CPF contribution, employees below 35): Approximately 23% of wages go to OA for those under 35, stepping down as workers age toward 55 when the focus shifts to building the Retirement Account. The OA earns a guaranteed minimum interest of 2.5% per annum, with an extra 1% on the first S$20,000 for members below 55 (subject to CPF Board updates each year).
As at April 2026, the CPF Board eliminated the Special Account for members aged 55 and above (CPF SA Closure 2025), moving OA/SA balances into the Retirement Account up to the Full Retirement Sum (FRS: S$213,000 for those turning 55 in 2026).
CPF OA Use 1: Housing Purchases
The most common OA use is funding property purchases — both HDB flats and private residential properties in Singapore. OA funds can be applied toward:
- Down payment: Initial cash component + OA funds for the remainder up to the CPF housing withdrawal limit.
- Monthly mortgage repayments: For HDB loans (2.6% interest, 0.1% above OA rate) and bank loans — OA is debited automatically each month.
- Stamp duty and legal fees: OA can pay these on top of the purchase price.
The CPF housing withdrawal limit is capped at the Valuation Limit (VL) — generally the lower of the purchase price or property valuation. Once VL is hit, further CPF usage is restricted unless you set aside the Basic Retirement Sum (BRS: S$106,500 for 2026 cohort). On sale, CPF used plus accrued interest at OA rate must be refunded to your CPF.
CPF OA Use 2: CPFIS Investments
Via the CPF Investment Scheme (CPFIS-OA), you can invest OA funds in approved instruments including: SGX-listed shares and REITs, Singapore unit trusts, ETFs, endowment insurance policies, and gold (up to 10% of investible savings). This allows OA funds to potentially earn above the 2.5% OA rate — but comes with market risk.
Key CPFIS-OA rules: You must maintain a minimum balance of S$20,000 in your OA before investing. Only amounts above S$20,000 are investible. If your investments underperform the OA interest rate, you are financially worse off — historically, many CPFIS investors have lagged the OA’s guaranteed 2.5% p.a.
For most retail investors, CPFIS-OA is best used for SGX-listed S-REITs or the NIKKO AM Singapore STI ETF (a low-cost proxy for the STI), which have historically outperformed the OA rate over 10-year periods. Avoid high-fee actively managed unit trusts that eat into your net return.
CPF OA Use 3: Education
OA funds can be used to pay tuition fees at approved Singapore educational institutions for yourself, your children, or other dependants. This applies to local polytechnics, universities, and some private institutions accredited by the CPF Board. The loan accrues interest at the OA rate and must be repaid to your CPF after graduation.
CPF OA Use 4: Insurance Premiums
OA can fund certain CPF-approved life insurance premiums — specifically the Dependants’ Protection Scheme (DPS, group term life up to S$70,000) and some MediShield Life components. Home Protection Scheme (HPS) premiums — which cover your outstanding HDB loan in case of death or permanent disability — are paid automatically from OA each year.
OA Interest Rate and Transfer to SA/RA
The OA earns 2.5% per annum guaranteed (extra 1% on first S$20,000 for under-55). To earn a higher rate, members under 55 can voluntarily transfer OA funds to the Special Account (pre-SA Closure) — earning 4% p.a. — or to the Retirement Account after 55. However, transfers to SA/RA are irreversible, so only transfer amounts you don’t need for housing or CPFIS investments.
As at 2026, with the SA closed for above-55 members, the OA-to-RA transfer strategy remains relevant for building up the FRS or ERS (Enhanced Retirement Sum: S$426,000 for 2026). Hitting the ERS gives the maximum CPF LIFE monthly payout at draw-down age.
Frequently Asked Questions
Can I use CPF OA to buy private property in Singapore?
Yes, CPF OA can be used to purchase private residential properties in Singapore, subject to the Valuation Limit and maintaining the Basic Retirement Sum in your CPF if you are 55 and above. The total CPF usage (OA) is capped at the Valuation Limit of the property.
What is the CPF OA interest rate in 2026?
The CPF Ordinary Account earns a guaranteed base interest rate of 2.5% per annum in 2026. Members below 55 receive an additional 1% interest on the first S$20,000 in their OA (combined with SA/MA), subject to the prevailing CPF Board rate announcement.
How much CPF OA can I invest via CPFIS?
You can invest CPF OA funds above the minimum S$20,000 threshold via CPFIS-OA. For example, if you have S$50,000 in your OA, you can invest up to S$30,000. Investible amounts can go into SGX-listed shares, REITs, ETFs, unit trusts, and gold (up to 10% of investible savings).
Should I transfer my CPF OA to SA?
Transferring OA to SA (for members under 55 before the SA Closure date) earns an extra 1.5% interest (SA rate: 4% vs OA: 2.5%). However, the transfer is irreversible — you lose access for housing or CPFIS. Consider transferring only funds you are certain you won’t need for housing repayments or investment purposes.
What happens to CPF OA when I sell my HDB flat?
When you sell your HDB flat, all CPF OA funds used for the purchase — plus accrued interest at the OA rate (2.5% p.a.) — must be refunded to your CPF account. This is called the CPF accrued interest refund. The refunded amount may be used for your next property purchase or to boost your Retirement Account balance.
