“Calin, our flat can sell for $650,000. So we’ll have about $500,000 to put into the condo, right?”
I wish I could say yes every time. (I am a human too, I like giving good news.) But the truth is, the selling price and the money you actually walk away with are two VERY different numbers.
Last month a lovely couple sat across from me with their own spreadsheet. They had subtracted their outstanding loan and assumed everything else was theirs to spend. When I showed them the CPF refund and its accrued interest, the room went quiet. Their cash was less than half of what they had planned for.
Nothing was wrong with their flat. Nobody was cheating them. They just hadn’t been told how HDB sale proceeds work.
And with HDB resale prices easing for a third straight quarter in URA’s latest flash estimates, every dollar matters more than before. So let me walk you through it, the same way I do with my sellers before we even talk about listing.
How HDB sale proceeds are paid out, in order
When your sale completes, the money doesn’t land in your bank account in one lump sum. It’s paid out in a fixed order:
(1) Your outstanding housing loan is cleared first. Whether it’s an HDB loan or a bank loan, the lender gets paid before anything else.
(2) Anything you owe HDB is deducted next. This includes outstanding upgrading costs, any upgrading levy, and arrears. If you are buying a second subsidised flat and have already collected its keys, your resale levy is deducted here too.
(3) Your CPF is refunded. This is the CPF principal you used for the flat, PLUS the accrued interest on it, plus any housing grants and their interest. It all goes back into your CPF account, not your pocket.
(4) Whatever is left is your cash proceeds.
Most people remember step 1. Step 3 is the one that surprises them.
The CPF refund: the part nobody warns you about
Every dollar of CPF you used for your flat (the downpayment, the stamp duty, every monthly instalment paid from your Ordinary Account) has to be returned when you sell.
And not just the dollar itself. CPF also adds back the interest that money WOULD have earned if it had stayed in your Ordinary Account. That rate is 2.5% a year today, compounded. CPF calls this “accrued interest”.
Two things make it bigger than people expect:
(1) It keeps growing even after your loan is fully paid. Accrued interest is calculated on the CPF you withdrew, not on what you owe the bank. So a flat you paid off ten years ago is still accruing interest today.
(2) It compounds over a long time. A $100,000 downpayment made 14 years ago has grown to roughly $141,000 at 2.5% a year. You need to refund all of it.
Here’s the good news, and I always say this slowly: this money is still yours. It goes back into your CPF Ordinary Account, and you can use it for your next home. It is not a fee or a penalty. It is your retirement savings being put back where it belongs. The catch is that it isn’t CASH, so it can’t pay for things CPF won’t cover, like renovation, furniture, or the cash portion of a condo downpayment.
Pro-tip : Log in to your CPF Home Ownership dashboard and look at the “What Happens If” section. It shows exactly how much you’d need to refund if you sold today. Please do this BEFORE you sign anything. It takes five minutes and it is the most useful number in the whole exercise.
A worked example: what your HDB sale proceeds really look like
Let me use a typical upgrader couple. The numbers are rounded and for illustration only.
They bought a 4-room resale flat 14 years ago. Over the years they have used $230,000 from their CPF for it. They still owe $110,000 on their HDB loan. They sell at $650,000.
(1) Selling price: $650,000
(2) Less outstanding HDB loan: –$110,000
(3) Less CPF refund ($230,000 principal + about $66,000 accrued interest): –$296,000
(4) Cash proceeds: $244,000
So from a $650,000 sale, about $296,000 goes back to their CPF and $244,000 is cash.
And they still have selling costs to pay from that cash: agent commission (negotiable, plus 9% GST) and conveyancing fees. If they are moving to a condo, the cash has to cover the minimum 5% cash downpayment, the Buyer’s Stamp Duty that’s payable before their CPF can be used, and renovation. Suddenly $244,000 is not as roomy as it sounded.
That couple from last month? We redid the plan together, and they still upgraded, just with a more realistic budget and a timeline that didn’t keep them up at night. Happy clients. Happy agent.
What if the sale proceeds aren’t enough to refund your CPF?
This worries many older homeowners, especially those with an older flat and a lot of CPF used over the years.
Imagine a flat that sells at market value for $380,000. The owner still owes $90,000 on the loan, and the CPF refund due is $320,000. After the loan is paid, only $290,000 is left, which is $30,000 short of the full refund.
Do they need to top up the $30,000 in cash? No. CPF is clear on this: if you sold at market value, you only refund what’s left after the loan, and the shortfall is NOT topped up in cash. In this example, the whole $290,000 goes to CPF and there is no cash left.
Two things to watch here:
(1) “At market value” matters. If you sell BELOW market value (to a relative at a “friendly” price, for example), you may have to make up the full refund in cash. Please talk to me before agreeing to a family discount.
(2) The deposit you received counts. The option fee and exercise fee your buyer paid you in cash (up to $5,000 in total for an HDB resale) are treated as part of the selling price. If your CPF refund isn’t fully covered, that money may need to go back into CPF too. Don’t spend the deposit before completion!
If you are 55 or older
The rules change slightly once you turn 55, so I want to flag this separately.
Your CPF refund will first be used to top up your Retirement Account to the Full Retirement Sum. Only the balance stays in your Ordinary Account. If you pledged your property to meet your retirement sum, the pledged amount must be refunded too.
This doesn’t mean the money is lost. It means higher CPF LIFE payouts later. But if you planned to use those proceeds for your next home, the numbers need checking. There is a helpful exception: if you buy a 3-room or smaller HDB flat within 3 years of selling, and it costs less than your old flat sold for, you may be able to use your Retirement Account savings above the Basic Retirement Sum for it.
I’ve walked several clients through this, including one who owned an HDB flat after 55 and another who upgraded to a condo at 55. Every case was different, so please don’t rely on a rule of thumb here.
Buying another HDB flat with a second HDB loan? Read this
If you plan to take a second HDB housing loan for your next flat, HDB doesn’t let you keep all of your cash proceeds.
You must put your full CPF refund (you may keep up to $20,000 in your Ordinary Account) and part of your cash proceeds towards the new flat before HDB grants the loan. Generally, you can keep the higher of $25,000 or 50% of your cash proceeds, including the deposit you received.
In our worked example, the couple would keep $122,000 of their $244,000 cash. The other half goes into the next flat.
Many sellers find this out only at the HFE letter stage. Plan for it early.
Three ways to get more from your HDB sale proceeds
(1) Check your CPF refund before you price your flat. Your asking price and your timeline should be built around the cash you’ll actually receive, not the headline price.
(2) Consider a voluntary housing refund, if it suits you. You can return CPF to your account in cash before you sell, which reduces the refund later. It doesn’t create more money. It simply moves it into CPF earlier, where it earns interest. Whether it makes sense depends on your cash needs, so think it through first.
(3) Get the order of selling and buying right. If you need your cash proceeds for the next purchase, the timing between your sale and your new purchase becomes critical. I wrote a whole guide on whether to sell first or buy first, because it’s the question every upgrader asks me.
If your sale is happening because of a divorce, the CPF refund is split according to how much each of you used, and the cash split is a separate conversation. I explain this gently in my guide on what happens to your property when you divorce.
My honest advice before you sell your HDB flat
A good sale isn’t only about the highest price. It’s about knowing, before you start, how much cash and how much CPF you’ll end up with, and whether that’s enough for your next home.
When I sit down with my sellers, the very first thing we do is this calculation. Sometimes it confirms the plan. Sometimes it changes it completely. Either way, I’d rather you find out at my dining table than at your lawyer’s office.
