Tracking CPF allocations across different age groups
For the past three years, I have been logging my own CPF statements in a spreadsheet, line by line, every quarter. What began as a casual check on monthly contributions turned into a quiet fascination with how the four CPF accounts fill up, slow down, and rebalance as birthdays tick by. My interest sharpened when a cousin in Perth asked me how the system compares with Australian superannuation, which prompted me to put pen to paper on the whole age-based mapping.
This write-up pulls from my own observations, scattered across conversations with relatives in Singapore, alongside notes I picked up on a recent trip through Sydney and Melbourne. I am not a financial adviser, and the figures below are drawn from CPF Board statements and published allocation tables. The aim is simply to share what the numbers look like at each life stage, with a few reflections on how this private savings engine sits beside the way Australians think about their retirement pot.
The four-account CPF framework
Singapore's CPF splits mandatory contributions into four accounts: the Ordinary Account, the Special Account, the MediSave Account, and the newer Retirement Account. Each one has a distinct purpose, ranging from housing and investments to healthcare and lifelong payouts. The way employer and employee shares are split into these buckets depends almost entirely on the contributor's age, which is why the framing of allocation by age group is genuinely useful rather than just bureaucratic repetition.
The Ordinary Account carries the lowest interest floor at 2.5 percent, while the Special, MediSave, and Retirement Accounts all earn 4.0 percent on the first S$60,000 of combined balances, then 4.0 percent on the next S$30,000 held in the Retirement Account. These floors matter because they set a baseline against which I benchmark any voluntary top-up or Singapore Savings Bond purchase. I sometimes look up the latest ssb rates page on this very blog to compare what I could earn on top of the statutory floor.
What I appreciate about the framework is how each account nudges a different behaviour. The Ordinary Account pushes me towards property decisions or cash. The Special Account penalises early withdrawal with its higher interest. MediSave quietly grows in the background, and the Retirement Account is a long-term payout engine I will only fully tap into decades from now.
Allocations in the early working years
In one's 20s and early 30s, the allocation ratios tilt heavily towards the Ordinary Account. For employees below 55, around 23.5 percent of the total CPF contribution goes into the Ordinary Account, with smaller slices flowing into the Special, MediSave, and Retirement buckets. This phase is also when property down payments and BTO ballot attempts usually happen, which explains why so much of the paycheck is steered into the more liquid account.
Looking back at my own statements from age 27, the Ordinary Account filled fastest, while the Special Account crawled along with just under 7 percent of total monthly allocations. The Retirement Account did not yet exist in its current form, so the Special Account was doubling as the high-interest engine back then.
This stage also tends to overlap with the spending stretch most Australians would recognise from their own early-career years, even with different acronyms. A friend in Brisbane once told me about kitting out her first apartment, and the math around saving for a deposit felt oddly familiar to my own CPF-OA-driven goal of building a BTO down payment.
Mid-career shifts
Once a contributor crosses the mid-career threshold, usually somewhere between 35 and 50, the allocation pie begins to reweight. The Special Account share gradually increases as the Ordinary Account slice decreases, and from age 55 onwards there is a fuller pivot into the Retirement Account. The official allocation tables shift incrementally every few years, so it is less a single cliff than a gentle slope, but the directional change is consistent.
Here is a simplified snapshot of how the percentages move across three life stages for an employee earning above the S$750 monthly threshold. These figures are rounded for clarity and pulled from CPF Board allocation charts and my own records.
| Age Band | Ordinary Account | Special Account | MediSave Account | Retirement Account |
|---|---|---|---|---|
| Below 35 | 23.5% | 6.5% | 8.0% | – (held in SA) |
| 35–45 | 21.5% | 7.5% | 9.0% | – (held in SA) |
| 45–50 | 18.5% | 9.5% | 10.5% | – (held in SA) |
| 55–60 | 12.5% | 4.0% | 11.5% | 16.0% |
| 60–65 | 4.5% | 0.5% | 10.5% | 28.5% |
| 65–70 | 2.5% | 0.0% | 9.5% | 29.5% |
Reading across the rows, the Ordinary Account share is almost halved by the late 50s, while the Retirement Account grows to claim the largest slice. MediSave creeps up steadily because healthcare spending typically rises with age, and the system's architects have clearly anticipated that pattern.
In Australian terms, the comparison is broadly similar to how the Superannuation Guarantee continues to flow into your super account regardless of age, although the Australian system does not split super into four parallel pots. The closest local analogue would be how a worker in Sydney might split voluntary contributions between an industry fund and a separate investment-linked account, but the mechanics are far less prescriptive.
Approaching the withdrawal age
The most eye-opening change happens at age 55, when the Retirement Account is created using combined balances. From that point, monthly payouts are calculated based on the higher of the Retirement Account balance or the Full Retirement Sum, currently S$205,800 for those turning 55 in 2024. Anything above the Basic Retirement Sum is gradually transferred into the Retirement Account, while amounts above the Full Retirement Sum become Additional Retirement Savings that earn the same base interest.
In my own records, the year I turned 55 was when my statement layout visibly changed. The Special Account column shrunk to a barely used row, and the Retirement Account took its place as the dominant balance. I had mentally prepared for this, but seeing it in print still made the shift feel real, similar to the way Australians approaching their preservation age start receiving letters about how their super will transition into pension-phase drawdowns.
A useful observation here is that Retirement Account interest is tax-exempt within certain caps, which is one of the quiet ways CPF behaves more like a tax-advantaged wrapper than a plain savings account. Reading my monthly statements in a café in Adelaide once, I realised how rarely this benefit gets compared head-to-head with the way Australian super earnings are taxed at concessional rates.
Observations from real statement pages
A few patterns have emerged from my own spreadsheet and from informal chats with co-workers and family. The Ordinary Account tends to peak early and slowly drain once housing obligations are settled, since most contributors stop topping it up voluntarily once they have used it for a property purchase. MediSave growth runs in a remarkably straight line for most contributors, simply because the allocation rarely drops and withdrawals tend to be lumpy rather than monthly.
The Retirement Account's real power shows up in the late 60s and beyond, when the compounding interest on a larger balance can exceed monthly cash payouts from many private annuities. I have also noticed that voluntary top-ups to the Special Account, before it merges into the Retirement Account, flatten out anyone's retirement shortfall earlier than late-career cash transfers.
This is one reason the fixed deposit comparison write-up on this site matters: it helps me decide whether to lock cash into a bank product or to channel spare money into CPF-SA where the 4 percent floor beats most fixed deposit rates for a retiree.
A side note on lifestyle spending: while the focus here is retirement, I still keep a running tally of discretionary outgoings, including my monthly indulgence of seasonal fruits. For a snapshot of how that compares with weekend market prices closer to home, I recently published a monthly exotic fruit tracker that doubles as a small reminder that enjoyment and retirement planning can coexist in the same household budget.
Drawing parallels with the Australian super system
Stepping back from CPF specifics, the Australian superannuation system shares the same philosophical backbone: forced savings during working life, tax preferences, and age-based rules that change what you can touch. Australia's preservation age currently sits between 59 and 60 for most workers, with the Superannuation Guarantee at 11.5 percent of ordinary time earnings, set to rise to 12 percent by 2025.
Where the two systems differ sharply is in granularity and liquidity. CPF locks funds into purpose-built accounts with strict withdrawal rules, while Australian super is broadly one pooled balance accessible only after preservation age. Singaporeans can use CPF for housing, education, and healthcare in ways Australians cannot use super, which means the two systems shape household behaviour quite differently even though both ultimately aim for a dignified retirement.
What I tell anyone asking me about whether one system is "better" is that the comparison is rarely a clean one. A young professional in Parramatta with a stable job and rising wages might find the Australian system straightforward, while a Singaporean relative in Toa Payoh could unlock property equity decades before retirement. The right answer depends on whether the household needs early liquidity or a guaranteed late-life payout.
Practical habits worth keeping in mind across both systems:
- Track the official allocation tables every year or two, since even small percentage shifts compound over decades.
- Match voluntary top-ups with your highest-interest account first, especially the Retirement Account once created.
- Keep at least six months of expenses in a separate liquid bucket outside CPF or super, so forced savings do not become a forced emergency fund.
- Revisit your property and healthcare plans in line with your age band, since the allocation tables themselves reflect those life priorities.
