CPF for Dummies: What You Actually Need to Know When You Start Working

Growing up, nobody in my family talked about money. Not in a secretive way — it just wasn't a topic. My parents worked hard, paid bills, and told me to study. Personal finance wasn't something that was taught at home or in school. I think that's true for a lot of Singaporeans.

So when I got my first payslip, I did what most people do: stared at it for five minutes, felt confused, and moved on. I knew my monthly salary. I didn't fully understand why the bank deposit was smaller, what "CPF" actually meant, or whether I was supposed to be doing anything with it.

This is the explainer I wish someone had given me at 22. Not the full textbook version — just enough to actually understand what's happening to your money.

What CPF actually is

CPF (Central Provident Fund) is a mandatory savings scheme run by the government. Every month, a percentage of your salary is set aside automatically — you contribute some, and your employer tops it up. For most employees under 55, the total is 37% of your salary: 20% from you, 17% from your employer.

On a $4,000 salary, that's $800 from you and $680 from your employer — $1,480 going into CPF every month. Your take-home becomes $3,200. The CPF money is yours, it's just locked in separate accounts with different rules.

That money goes into three accounts: Ordinary Account (OA), Special Account (SA), and MediSave. Each has different rules for what you can use it for.

The three accounts explained simply

Ordinary Account (OA) — 2.5% interest

This is the most flexible account. You can use OA money for: buying an HDB flat (downpayment and monthly loan repayments), paying for CPF-approved investments (stocks, ETFs via CPF Investment Scheme), and education loans.

The interest rate is 2.5% per year, guaranteed. That's better than most bank savings accounts for money you won't need in the short term. The catch: once you've used it for a house, it's gone until you sell.

Special Account (SA) — 4% interest

SA is basically your retirement account. The interest rate is 4% — significantly better than OA — but the tradeoff is you can't touch it until you're 55, and even then only under certain conditions. SA money is for retirement, not anything else.

One thing worth knowing: you can voluntarily top up your SA with cash (up to the Full Retirement Sum cap) to earn the guaranteed 4%. It's basically a risk-free 4% that beats most savings accounts — the tradeoff is you can't touch it until retirement.

MediSave — 4% interest

MediSave covers healthcare: hospitalisation bills, approved outpatient treatments, MediShield Life premiums (Singapore's compulsory health insurance), and some approved health screening. It also earns 4% interest.

You don't need to actively manage MediSave — MediShield Life premiums are deducted automatically. But it's worth knowing the balance is there for medical expenses.

All three earn interest automatically. You don't have to do anything — the money just grows while it sits there.

How the contributions split (with real numbers)

For someone below 35, the 37% total contribution splits across accounts roughly like this:

The numbers shift slightly as you get older (CPF contribution rates change at 55, 60, 65). But for most people just starting out, 37% is the number to remember.

The first thing to sort: a savings account

Most people just leave their salary sitting in whatever account the bank gave them when they were 15. That account is probably earning 0.05% interest. There are options that earn 20–30x that on the same money, just for doing things you're already doing — like crediting your salary and using a debit card.

Don't overthink this. Pick whichever Big 3 account pairs with the card you'll actually use, credit your salary there, done. You can always switch later. The main thing is not leaving money in a basic passbook account earning 0.05%. (I wrote a deeper breakdown of savings account traps and how to actually compare them.)

Getting your first credit card

A lot of people avoid credit cards because their parents told them cards are dangerous. And they're right that carrying a balance is dangerous — the interest rate is around 26% per year, which means debt compounds faster than almost any investment can keep up with.

But if you pay the full bill every month — which you absolutely should — a credit card is just a cashback machine. You're spending money you would have spent anyway, and getting 1.5–5% back on it. For someone spending $1,500/month on everyday purchases, that's $20–75 back every month for doing nothing differently.

For a first card, go cashback. Look for no annual fee (or easy waiver). DBS Live Fresh, OCBC 365, and UOB One cashback are common starting points. Your bank will often offer you a card when you open a salary account — ask if they'll waive the fee. (I wrote a separate article on credit card traps in Singapore that goes deeper into what the fine print actually hides.)

Emergency fund first, investing second

The unsexy but genuinely important one. Before you put money into any investment, build a cash cushion first — typically 3–6 months of your expenses. For most people in their mid-20s, that's roughly $8,000–15,000 sitting in an accessible savings account.

This isn't money for investing. It's your financial safety net — for if you lose your job, get hit with a medical bill your insurance doesn't cover, or have some other unexpected cost that needs cash fast. Without this, you might end up having to sell investments at exactly the wrong time (markets dip, you need money, you sell at a loss) or worse, rack up credit card debt.

Once you have it, stop building it. The point isn't to hoard cash forever — 3–6 months is enough. Beyond that, the money is better off invested.

Order of operations: emergency fund first → pay off any credit card debt → then invest. Putting money into a robo-advisor while carrying credit card debt at 26% interest is just moving money in circles.

One more thing: SRS

The Supplementary Retirement Scheme (SRS) is worth knowing about, even if you don't use it immediately. You can contribute up to $15,300/year (for Singapore citizens), and every dollar you put in reduces your taxable income by that amount — meaning a tax refund roughly equal to your marginal tax rate.

For someone in the 7% tax bracket (chargeable income $40,000–80,000), putting $10,000 into SRS saves $700 in taxes. The money can be invested in stocks, ETFs, or unit trusts within the SRS account. It's locked until 62, but with a penalty for early withdrawal rather than fully inaccessible.

Most people don't need to worry about SRS in year one — sort your emergency fund and a savings account first. But knowing it exists, and that it becomes more valuable as your income grows, puts you ahead of most people your age.

The actual checklist for your first year of work

1. 1.Open a salary account at DBS, OCBC, or UOB. Credit your salary there and pick a matching credit card.
2. 2.Set up credit card autopay to clear the full balance monthly. Non-negotiable.
3. 3.Build an emergency fund of 3–6 months of expenses before anything else. Boring but foundational.
4. 4.Track your spending for 2 months. Just observe — no restrictions yet. You need real numbers before you can make real decisions.
5. 5.Once the emergency fund is funded, start investing a fixed monthly amount into low-cost index ETFs (STI ETF on SGX, or global ETFs like IWDA via a brokerage).
6. 6.Toward the end of the year, look at SRS if your income is high enough to pay meaningful income tax.

None of this is complicated. The hard part is just that nobody tells you any of this when you start working. You finish school, land the job, get the payslip, and you're basically on your own. Most people in their mid-20s are either doing nothing or copying what their colleagues mention at lunch. Neither is a strategy.

A bit of structure early — even imperfect — puts you meaningfully ahead. The compounding works in your favour the earlier you start. That's the one thing every finance article gets right.
