Your CPF savings are not held in a single lump. They are divided into separate accounts, each doing a different job for a different stage of life. Once you understand how the CPF accounts Singapore uses fit together, the whole system makes far more sense: why some money is earmarked for housing, some for healthcare, and some for retirement. This guide walks through each account, how contributions are shared out, how interest works in general terms, and the important shift that happens at age 55. It keeps to the mechanics and points you to the CPF Board for any current figures.
The Four CPF Accounts and What They Do
While you are working, most people have three main CPF accounts. A fourth appears later. Here is the shape of it.
- Ordinary Account (OA): The most flexible of the accounts. It is used mainly for housing, and under CPF rules it can also support certain insurance, approved investments, and education needs.
- Special Account (SA): Built for retirement and longer term savings. It generally earns a higher interest rate than the OA and has tighter rules on use, reflecting its long horizon.
- MediSave Account (MA): Reserved for healthcare. It pays for approved hospital and medical costs and for premiums under national medical insurance schemes.
- Retirement Account (RA): Created when you turn 55, drawing together savings to provide income in retirement.
Each account is a tool for a purpose. The OA is your near term and housing account, the SA and RA are your retirement accounts, and the MA is your health account. Keeping that mental model makes the rest easier to follow.
The Ordinary and Special Accounts
The Ordinary Account is where many Singaporeans first put CPF to work, because it can go toward a home. Savings here can help fund the purchase of a flat or property and related payments, subject to CPF rules and limits. Beyond housing, the OA can be used for certain approved investments through the CPF Investment Scheme and for some education costs, again within the conditions the CPF Board sets. Because it is the most accessible account, it also tends to earn the lowest CPF interest rate of the group.
The Special Account is quieter but powerful. It is designed to sit and grow for retirement, and it generally earns a higher rate than the OA. The trade off is less flexibility: the SA is not meant for everyday or housing use in the same way. Over a long career, the higher interest and the discipline of leaving it untouched are precisely what help retirement savings compound.
The MediSave Account
MediSave is your dedicated healthcare account, and it is one of the most reassuring parts of CPF. It can be used for approved hospital stays, day surgery, certain outpatient and chronic treatments, and premiums for national medical insurance such as MediShield Life. Because healthcare costs can arrive suddenly and be large, having a ring fenced pool for them reduces the risk of a medical event derailing your finances.
MediSave has its own rules on how much can be used for particular treatments and on annual limits for certain uses, and there is a ceiling on how much can accumulate in the account. These figures are set by the CPF Board and are reviewed over time, so check the current limits on the official CPF website rather than relying on a remembered number.
How Contributions Are Allocated
When a CPF contribution is made, it is split across your accounts. The important thing to understand is that the split is not fixed for life. The proportion flowing into the OA, SA, and MA changes as you move through age bands, and the exact percentages are determined by the CPF Board.
In broad terms, younger workers tend to see more of their contribution directed toward the Ordinary Account, which supports housing early in life, while the share moving toward retirement and healthcare shifts as you get older. That is the general pattern, but the precise allocation percentages change and should never be quoted from memory. Always confirm the current allocation table on the CPF website.
Here is a plain summary of each account and its main uses:
| CPF account | Main uses |
|---|---|
| Ordinary Account (OA) | Housing, approved investments, certain education and insurance uses |
| Special Account (SA) | Retirement savings, generally at a higher interest rate |
| MediSave Account (MA) | Approved healthcare costs and national medical insurance premiums |
| Retirement Account (RA) | Retirement income from age 55 onward |
Interest and the Move to a Retirement Account
CPF savings earn interest, and the accounts are not all treated the same way. In general terms, the retirement oriented accounts tend to earn more than the Ordinary Account, and there have historically been additional interest arrangements for certain balances and for older members. The actual rates are set and revised by the CPF Board, so verify the current CPF interest rates on the official site before you plan around any number.
The most significant change happens at 55. At that point a Retirement Account is created for you. Savings from the Special Account, and then the Ordinary Account, are drawn together into the RA up to the applicable retirement sum, and this forms the basis for your future retirement payouts. The Special Account’s role changes through this transition, and the details, including the relevant retirement sums, are governed by CPF Board rules that evolve. When you approach 55, read the current rules directly so you understand exactly what will happen to your balances.
Making the Accounts Work for You
You do not need to memorise every rule to benefit from CPF. A few sensible habits go a long way:
- Log in with Singpass to the CPF Board’s official services to see each account balance and your contribution history.
- Before a home purchase, check what your OA can be used for under the current rules.
- Before any CPF investment, understand that the CPF Investment Scheme has its own conditions and that all investing carries risk, including loss of capital.
- For any percentage, ceiling, or rate, treat the CPF Board as the source of truth.
A Note on This Guide
This article is general information about how CPF accounts in Singapore work, not financial advice. Your age, goals, and circumstances matter, so consider them and, where relevant, consult a licensed financial adviser or the CPF Board before deciding. Do not act on any specific rate, allocation, or limit that you have not confirmed with the official source.
