If you’ve ever spoken to a friend who just sold their HDB flat, you may have heard a familiar refrain: “I thought I’d pocket a lot more cash.” Many homeowners walk away from their sale feeling surprised — sometimes even disappointed — at how little money actually makes it into their bank account.
That’s because before you see a single dollar in cash proceeds, the money you’ve drawn from your CPF Ordinary Account (OA) — along with accrued interest and any housing grants received — must be refunded to your CPF. It’s not an optional step; it’s a mandatory process designed to safeguard your retirement savings.
In this article, we’ll cut through the confusion and explain exactly what needs to be refunded, how much of your sale proceeds will go back into CPF, and what happens to those funds once they’re returned. By the end, you’ll know what to realistically expect when selling your HDB — and why your CPF account, not your bank account, might end up the biggest winner.
🏠 What Happens to Your CPF When You Sell Your HDB?
When you sell your HDB flat, don’t expect the full sale price to land neatly in your bank account. The proceeds go through a structured sequence of deductions, and CPF refunds sit high on that list.
If you’ve used your CPF Ordinary Account (OA) savings to finance your flat, the principal amount withdrawn plus the accrued interest must first be refunded back to your CPF. Accrued interest may sound like a penalty, but it isn’t — it’s the 2.5% yearly interest your CPF savings would have earned had you left the money in your OA. Think of it as a way to ensure your retirement pot keeps growing, even if you used those funds for housing.
Here’s the typical flow of your sale proceeds:
Outstanding loan repayment — Any remaining HDB or bank housing loan is cleared first.
CPF refund — Principal CPF used + accrued interest go back into your CPF account.
CPF Housing Grants refund — If you received grants (e.g. Family Grant, Enhanced Housing Grant), these are also refunded with interest.
Cash proceeds — Only after these steps are done will any remaining balance be disbursed to you in cash.
In short: your CPF account gets replenished before your wallet does.
💰 What Must Be Refunded?
When your HDB flat is sold, several components must be returned to your CPF before you can touch any cash proceeds. These refunds aren’t optional — they’re part of the rules that ensure your CPF savings remain intact for retirement. Here’s what goes back:
CPF principal withdrawn: The actual amount you used from your CPF Ordinary Account (OA) to pay for the flat, whether for downpayment, monthly instalments, or related costs.
Accrued interest: The 2.5% per year your CPF savings would have earned if they had stayed in your OA. This ensures your retirement funds keep compounding as though they were never withdrawn.
CPF Housing Grants: Any grants you received — such as the Enhanced Housing Grant or Family Grant — must be refunded in full, along with their accrued interest.
Retirement Account pledge refund (if aged 55 or above): If you pledged your property to meet your Retirement Account (RA) requirement, the pledged amount must be refunded upon sale to restore your RA to the Full Retirement Sum (FRS).
Together, these make up the total CPF refund — and they take priority over any cash proceeds you may be expecting.
📊 Common Scenarios When Selling Your HDB
Not every HDB sale plays out the same way. The outcome depends on your selling price, outstanding loan, and CPF usage. Here are the three most common scenarios:
Selling at a Profit
If your flat sells for significantly more than your outstanding loan and CPF refund, you’ll have leftover cash proceeds after meeting all obligations. Your CPF gets fully refunded, and the balance flows to your bank account.Break-Even Sale
Sometimes the sale price is just enough to cover the housing loan and CPF refund. In this case, you may walk away with little to no cash in hand — but your CPF savings are replenished, ready for future housing or retirement needs.Negative Sale (Shortfall)
If your flat sells for less than the outstanding loan plus CPF refund, the rules protect you. As long as the transaction is done at market value, you don’t need to top up the shortfall in cash. However, any option monies (like the option fee and exercise fee) you’ve received must still be refunded to your CPF account.
🏦 Where Does the CPF Refund Go?
Where your CPF refund lands depends largely on your age and the type of funds involved. Here’s how it works:
If you’re below 55: All refunded amounts — principal, accrued interest, and housing grants — are credited back into your Ordinary Account (OA). These savings can later be used again for another property purchase, education, or kept for retirement.
If you’re 55 and above: Refunds are first channelled into your Retirement Account (RA) to make up the Full Retirement Sum (FRS). Only after your RA has been topped up will any excess be credited back to your OA. This ensures your retirement savings are prioritised.
Housing grants: If the grants refunded (with accrued interest) exceed $30,000, CPF may apportion the refund across different accounts — OA, Special Account (SA), RA, and MediSave Account (MA) — instead of crediting everything into the OA.
In short: refunds strengthen your CPF balances first, with the distribution guided by your age and grant usage.
🎁 Housing Grants, Resale Levy & PLH Clawback
When selling your HDB, it’s not just your CPF principal and accrued interest that go back — grants and other policy costs also come into play.
Housing grants: Any CPF Housing Grants you received (such as the Family Grant or Enhanced Housing Grant) must be refunded in full, along with accrued interest. While this reduces your immediate cash proceeds, it replenishes your CPF savings for future use.
Resale levy: If you plan to buy another subsidised flat — like a BTO, resale with grants, or an Executive Condo — you’ll need to pay a resale levy. This levy ensures fairness by redistributing subsidies across different households. The levy is deducted directly from your sale proceeds.
| Flat Type | Singles Levy | Families Levy |
|---|---|---|
| 2-room | $7,500 | $15,000 |
| 3-room | $15,000 | $30,000 |
| 4-room | $20,000 | $40,000 |
| 5-room | $22,500 | $45,000 |
| Executive | $25,000 | $50,000 |
| Executive Condo (EC) | N/A | $55,000 |
PLH subsidy recovery (clawback): If your flat falls under the Prime Location Public Housing (PLH) model, you’ll need to return between 6% and 9% of your resale price as a subsidy recovery when you sell.
Together, these refunds, levies, and clawbacks can take a significant bite out of your expected cash proceeds — so it’s worth checking them early before planning your next move.
🏡 HDB Loan Rules After Selling
If you’re planning to buy another flat after selling your current one, HDB has rules on how your proceeds and CPF savings are handled before granting you a new loan:
Use of cash proceeds: You must use at least $25,000 or 50% of your cash proceeds (whichever is higher) towards your next flat purchase. You can’t simply keep all the cash from your sale.
CPF retention limit: You’re allowed to retain up to $20,000 in your CPF Ordinary Account (OA). Any balance above that must be used for your next flat.
Loan-to-Value (LTV) restrictions: If you’re taking a second HDB concessionary loan, the maximum loan amount is generally lower than for first-time buyers. HDB imposes stricter LTV limits to ensure you use your available resources first.
In short: if you’re upgrading or buying again, be prepared — not all of your proceeds are freely disposable, and HDB will expect you to channel both cash and CPF savings into your next home.
🔎 How to Check Your Refund Amount
Before you commit to selling, it’s wise to get clarity on how much of your sale proceeds will flow back into CPF. Thankfully, there are official tools that make this straightforward:
CPF Property Withdrawal Statement: Available on the CPF website, this statement shows exactly how much CPF you’ve used for your flat and the accrued interest that must be refunded.
CPF Home Ownership Dashboard: A personalized tool that gives you a clear breakdown of your refund obligations when selling, including CPF usage, interest, and grants.
HDB calculators: Use HDB’s online calculators to estimate your sale proceeds and check your resale levy payable if you’re planning to buy another subsidised flat.
By combining these resources, you’ll get a realistic picture of your CPF refund and the actual cash you can expect to walk away with after the sale.
⚠️ Key Things to Take Note Of
Selling your HDB flat isn’t just about finding a buyer — it’s about understanding how much you’ll actually keep after all the deductions. Here are the essentials to remember:
Accrued interest grows yearly: The longer you’ve held your flat, the larger the CPF refund required, since interest compounds at 2.5% annually.
Grants and accrued interest reduce cash proceeds: Even if your sale price looks healthy, refunds can eat significantly into your expected cash.
Negative sale rules protect you: If your proceeds after loan repayment can’t fully cover the CPF refund, you don’t need to top up the shortfall in cash — provided the sale is at or above market value.
Always check your statements: Review your CPF Property Withdrawal Statement and HDB resale levy details before selling. This ensures there are no surprises when the transaction is completed.
When you sell your HDB, your CPF refund comes first — covering the principal you used, the accrued interest, and any housing grants — before you see a single dollar in cash.
Because of these deductions, plus factors like resale levy and PLH clawbacks, your net cash proceeds are often much smaller than expected.
Before making a move, always check your CPF Home Ownership Dashboard and use HDB’s calculators or property valuation tools to get a clear picture of your proceeds. That way, you can plan your next step with confidence and avoid unpleasant surprises.
