Projected Outcome
Not financial advice. CPFIS returns are not guaranteed. CPF OA earns 2.5% p.a. on non-invested balances. First S$20,000 in OA cannot be invested.
Understanding CPF OA Investment for Singapore Investors
Every working Singaporean and Permanent Resident accumulates funds in their CPF Ordinary Account (OA), which earns a guaranteed 2.5% per annum — 3.5% on the first S$20,000. That guaranteed rate is one of the most competitive risk-free returns available in Singapore, but it also raises a persistent question: should you invest your CPF OA via the CPF Investment Scheme (CPFIS) to potentially earn more? This calculator helps you model both paths side by side, using your actual OA balance, a realistic expected return, and your investment time horizon — giving you a quantitative basis for your decision.
CPFIS was introduced by the CPF Board to allow members to invest their CPF savings in a range of approved instruments, from STI ETFs and Singapore-listed REITs to unit trusts and government bonds. The scheme is widely used, yet research has repeatedly shown that a significant portion of CPFIS participants underperform the benchmark 2.5% OA rate. With the US Federal Reserve raising rates to 3.75–4.00% in September 2026, many investors are revisiting the calculus on yield, risk and the genuine value of CPF’s guarantee.

The CPF OA Interest Rate: What You Actually Earn
The CPF OA interest rate has been 2.5% per annum for decades, pegged at the higher of 2.5% or the 3-month average of major local banks’ savings rates. In practice, 2.5% is always the floor. Crucially, the first S$20,000 in your OA earns an extra 1% — meaning it effectively earns 3.5% — but this extra interest is credited to your Special Account (SA) rather than OA. This S$20,000 is also ring-fenced: it cannot be invested via CPFIS under any circumstances. So when you model CPFIS investments, always subtract S$20,000 from your OA balance to find your true investable amount.
What CPFIS Allows You to Invest In
CPFIS-OA approved investments include Singapore Government Securities (SGS bonds), Singapore Savings Bonds (SSBs), STI-linked ETFs such as Nikko AM STI ETF and SPDR STI ETF, Singapore-listed equities on SGX, selected unit trusts and investment-linked insurance products, and gold (up to 10% of investable OA savings). Crucially, direct investment in overseas equities is not permitted through CPFIS — you must use a unit trust or ETF wrapper. Robo-advisors like Endowus are the most convenient way to access a diversified fund portfolio using CPF OA funds, as they handle all the CPF Board paperwork and fund selection for you.
How to Use This CPF OA Investment Calculator
- Enter your CPF OA Balance: Type or slide to your current OA balance. The calculator automatically deducts the mandatory S$20,000 non-investable floor to show your true investable amount.
- Set the % to Invest: Choose what proportion of your investable OA you want to deploy via CPFIS. At 100%, you invest everything above S$20,000. At 0%, you keep all funds in OA at 2.5%.
- Set Expected Annual Return: Enter the annual return you realistically expect from your CPFIS portfolio. 7% approximates long-run Singapore equity returns; adjust based on your strategy (bonds, REITs, global ETFs).
- Choose Your Time Horizon: How many years until you plan to access these funds? Longer horizons generally favour investing due to compounding, but also increase exposure to market volatility.
The calculator instantly shows you the projected CPFIS value, what the same amount would have grown to at 2.5% OA rate, the net gain or loss from investing, and your full OA portfolio value. A positive Investment Gain means investing outperforms the guarantee; negative means the OA floor would have served you better.

What Is the CPF Ordinary Account?
The CPF Ordinary Account is one of four CPF accounts that Singapore citizens and PRs hold. It receives the largest share of CPF contributions during the working years — 23% of gross salary for those below 55 under the current rates (as at Q3 2026) — and it earns a government-backed interest rate of 2.5% per annum. The first S$20,000 in the OA earns an additional 1% (effective 3.5%), but this extra interest is transferred to the Special Account or Retirement Account, not credited back to OA. This design encourages members to maintain a floor in OA while building the higher-yielding SA.
OA funds are versatile. Singaporeans use them for housing down payments and mortgage repayments (HDB and private), approved education loans, insurance premiums under the Home Protection Scheme, and investment via CPFIS. This multi-purpose nature makes OA one of the most important financial accounts for Singapore households — which is why any decision to divert OA funds into market investments deserves careful analysis. The 2.5% floor is not just an interest rate; it is effectively a floor on your opportunity cost every time you consider CPFIS.
As at Q3 2026, the CPF Board confirmed that the 2.5% OA rate remains unchanged despite elevated global interest rates. The Monetary Authority of Singapore (MAS) and CPF Board review rates quarterly based on a formula pegged to commercial bank savings rates, but the 2.5% statutory minimum has held firm since 1999.
How CPFIS Works: Investing Your CPF OA
The CPF Investment Scheme (CPFIS) was established in 1986 to allow members to invest their CPF savings with the goal of achieving returns exceeding the CPF interest rates. To participate in CPFIS-OA, you must first open a CPFIS-approved investment account with a participating bank or broker — DBS, OCBC, and UOB all offer linked CPFIS accounts, as do brokers such as FSMOne, POEMS, and DBS Vickers. Once linked, you can transfer OA funds (minus the mandatory S$20,000 floor) to your investment account.
Approved CPFIS-OA instruments include Singapore equities listed on SGX, selected unit trusts, Singapore Savings Bonds (SSBs), Singapore Government Securities (SGS bonds), Exchange Traded Funds (ETFs) linked to the STI such as the Nikko AM STI ETF and SPDR STI ETF, gold products (capped at 10% of investable OA savings), and selected investment-linked insurance products. Direct investment in overseas equities, cryptocurrencies, or Singapore corporate bonds is not permitted under CPFIS.
Robo-advisors have simplified CPFIS access significantly. Endowus is the only MAS-licensed robo-advisor in Singapore that manages CPF OA funds directly. It provides access to institutional share classes of leading global and Singapore funds at management fees starting from 0.25% per year — significantly lower than retail unit trust charges. The process is fully digital: link your Singpass, authorise the CPF withdrawal, and Endowus handles everything from rebalancing to fund switches.
CPF OA 2.5% vs CPFIS: The Maths
The core question is simple: can your investment return reliably exceed 2.5% after fees, over your chosen time horizon, with acceptable volatility? The calculator above models this precisely, but it is worth examining a concrete example.
Assume a 35-year-old Singaporean with S$100,000 in CPF OA invests S$40,000 (50% of their S$80,000 investable balance) via CPFIS in a diversified equity ETF returning 7% per annum. After 25 years (to age 60):
| Path | Amount Invested | Value at Age 60 |
|---|---|---|
| CPFIS at 7% p.a. | S$40,000 | S$216,961 |
| CPF OA at 2.5% p.a. | S$40,000 | S$74,591 |
| Net Investment Gain | – | +S$142,370 |
At 7% annual return, the investment advantage is enormous over 25 years. However, this assumes consistent 7% returns with no drawdowns — a scenario that ignores real-world volatility. The CPF Advisory Panel’s 2019 study found that from 2004 to 2016, 79% of CPFIS-OA members who invested in unit trusts would have been better off leaving funds in OA. The average CPFIS investor underperformed the 2.5% benchmark by approximately 0.4% per year after fees. The lesson: the guaranteed 2.5% is harder to beat than it looks, especially after fund management fees of 1–2% on actively managed unit trusts.
Best Platforms for CPF OA Investment in Singapore
Choosing the right platform materially affects your net return from CPFIS, since fees compound just as returns do. Here are the main options for Singapore investors as at Q3 2026.
Endowus (CPF-licensed robo-advisor): The only digital wealth manager that accepts CPF OA funds directly. Offers a diversified range of institutional share class funds across global equities, Singapore equities, REITs, bonds, and the Infinity Global Stock Index Fund. Access fee from 0.25% p.a. Fund-level fees typically 0.2–0.5% for passive funds. Best for: hands-off, long-term OA investors who want global diversification. Use our Endowus referral code for a welcome bonus on your first investment.
FSMOne (formerly Fundsupermart): A comprehensive online brokerage offering CPFIS-approved unit trusts, ETFs, and Singapore equities. No platform fee for CPFIS accounts; individual fund charges apply (typically 0.5–1.5% for active funds, lower for passives). Best for: investors who want to pick individual funds or STI ETFs. Visit our FSMOne referral page for current promotions.
DBS Vickers / POEMS / UOB KayHian: Full-service brokerages that allow direct equity and ETF investing via CPFIS. Brokerage commissions typically 0.12–0.28% per trade. Best for: investors who want to buy STI ETF directly, or individual SGX-listed REITs, without ongoing management fees. Note that CPFIS does not allow investing in overseas equities directly — a locally listed ETF or unit trust is needed for global exposure.
For those not ready to invest OA funds, Syfe offers an excellent platform for managing SRS and cash investments — keeping OA in the safe 2.5% while actively growing other buckets.
CPF OA vs SRS: Tax Efficiency Compared
Many Singapore investors face a choice between directing additional savings into CPFIS or into a Supplementary Retirement Scheme (SRS) account. These are not mutually exclusive — in fact, many high-income earners do both — but understanding the trade-offs helps you allocate strategically.
CPF OA contributions are mandatory and already tax-deductible via the CPF relief structure. The OA earns a guaranteed 2.5% with no investment risk on the floor balance. CPFIS adds investment risk to your CPF stack in pursuit of higher returns. SRS, by contrast, is a voluntary top-up scheme that provides an immediate income tax deduction — reducing your taxable income by up to S$15,300 (Singaporeans/PRs) or S$35,700 (foreigners) per year. SRS funds earn only 0.05% if left as cash but can be invested in the same universe of instruments as CPFIS, plus certain additional categories. Withdrawals before age 62 attract a 5% penalty plus full taxation; withdrawals after 62 are only 50% taxable.
For most working Singaporeans in the 7–22% income tax bracket, SRS contributions offer an immediate tax saving that can be substantial. Use our SRS Tax Savings Calculator to model your exact annual tax saving before deciding between investing OA via CPFIS or topping up SRS first. The general rule of thumb: maximise CPF SA top-up (for the 4% guaranteed rate) and SRS (for tax savings) before actively investing OA via CPFIS.
CPF OA Investment as a Long-Term Retirement Strategy
At its core, the CPFIS decision is a retirement strategy question. The CPF Board’s goal is to ensure members have adequate savings for retirement, and the guaranteed 2.5% OA rate plays a central role in that plan. When you choose to invest via CPFIS, you are trading certainty for the possibility of higher returns — a trade-off that depends on your risk tolerance, investment knowledge, cost discipline, and time horizon.
For investors with a 20–30 year horizon and the discipline to stay invested through market cycles, a low-cost diversified equity portfolio (particularly through Endowus or a direct STI ETF purchase) has historically outperformed the 2.5% benchmark. For investors within 5–10 years of retirement, the guaranteed floor becomes increasingly valuable — the risk of a market downturn just before you need the funds can be devastating to your retirement readiness.
Use our Retirement Planning Calculator to understand how much you need at retirement, and pair it with our DCA Investment Calculator to model regular monthly investment contributions.

And if you are considering CPF transfers from OA to SA to maximise the 4% guaranteed SA rate before age 55, our CPF OA/SA Allocation Calculator shows the long-term impact of that decision versus investing OA via CPFIS.
Frequently Asked Questions
What is the CPF OA interest rate in Singapore in 2026?
The CPF Ordinary Account earns 2.5% per annum, which is the statutory minimum set by the CPF Board. The first S$20,000 in your OA earns an additional 1% (effective 3.5%), but this extra interest is credited to your Special Account or Retirement Account, not your OA. As at Q3 2026, the 2.5% OA floor remains unchanged despite higher global interest rates.
How much of my CPF OA can I invest via CPFIS?
You can invest the amount in your CPF OA above S$20,000. This mandatory floor of S$20,000 must always remain in your OA and cannot be invested via CPFIS. For example, if your OA balance is S$100,000, your maximum investable amount is S$80,000. You do not have to invest all of it — you can choose any portion up to the S$80,000 ceiling.
Which platforms can I use to invest my CPF OA in Singapore?
The main CPFIS-approved platforms in Singapore are Endowus (the only robo-advisor licensed to manage CPF funds), FSMOne, DBS Vickers, POEMS (Phillip Securities), UOB KayHian, and OCBC Securities. Each platform offers different instruments and fee structures. Endowus is generally the most convenient for passive, diversified investing; full-service brokerages suit investors who prefer to pick individual REITs or ETFs directly.
Is it worth investing CPF OA or keeping it at 2.5%?
It depends on your investment approach, time horizon, and fee discipline. A 2019 CPF Advisory Panel study found that 79% of CPFIS-OA unit trust investors would have been better off earning 2.5% in their OA from 2004 to 2016. However, investors who used low-cost ETFs or index funds and maintained a long horizon (20+ years) have generally outperformed the OA benchmark. The key risk factors are high fund fees, poor market timing, and insufficient time horizon.
What is the minimum return I need to beat the CPF OA rate?
You need to earn more than 2.5% per annum net of all fees to beat the CPF OA rate on your invested amount. In practice, this means your gross investment return must exceed 2.5% plus your annual management fee. If you use a platform charging 1.5% per year in fund fees, you need gross returns of at least 4% to break even with OA. This is why low-cost index funds and ETFs are significantly better suited for CPFIS than actively managed unit trusts.
Can I invest my CPF OA in S-REITs?
Yes. Singapore-listed REITs (S-REITs) are approved CPFIS-OA investments, and you can buy them through a CPFIS-approved brokerage such as DBS Vickers, POEMS, or FSMOne. Many Singapore investors use CPFIS to hold REITs like Mapletree Logistics Trust, CapitaLand Integrated Commercial Trust, or Keppel DC REIT for their dividend distributions. Distributions are credited to your CPFIS investment account, not your OA directly.
What happens if my CPFIS investment loses money?
If your CPFIS investments fall in value, the loss is absorbed by your CPF account — your OA balance reflects the lower market value of the investment. Unlike the guaranteed 2.5% rate, CPFIS investments carry full market risk with no capital protection from the CPF Board. If your CPFIS portfolio value falls below the invested amount, you cannot claim the lost funds back. This is why maintaining the mandatory S$20,000 OA floor as a guaranteed buffer is an important part of prudent CPF investment management.
How does CPF OA investment compare to SRS investing in Singapore?
Both CPFIS (using OA) and SRS let you invest for retirement, but they differ in tax treatment. SRS contributions give you an immediate income tax deduction — reducing your taxable income dollar-for-dollar up to S$15,300 per year for Singaporeans and PRs. CPF contributions already receive a separate CPF tax relief. SRS withdrawals after age 62 are only 50% taxable; CPFIS gains are entirely tax-free since they remain within the CPF umbrella. For high-income earners, SRS often offers a higher immediate return (through tax savings) than trying to beat the OA rate via CPFIS.
What return should I use in the CPF OA investment calculator for Singapore?
For a diversified Singapore equity portfolio (STI ETF), historical returns have averaged around 6–7% per annum over long periods, though this includes significant volatility. For a balanced portfolio mixing equities and bonds, 4–5% is a reasonable projection. For a pure Singapore REIT portfolio, 7–9% (including distributions) has been achievable over the last decade, though REITs carry interest rate sensitivity. Always use the net-of-fees return in the calculator — subtract your annual platform and fund management fees from the gross expected return.
