Guide · Selling and CPF
Don't sell your HDB after 55 before you've done this math
If you're in your 50s and thinking about your next property move, downsizing, upgrading or whatever it is, read this before you make any decisions. I sat down with a client in their early 50s recently, looking at their next property steps, and in the conversation I realised something: there's one CPF rule most owners have absolutely no idea exists, and it directly changes how much cash you walk away with when you sell.
Prefer to watch? This guide follows the video, with the CPF rules behind it and ways to plan around it.
In short:
- When you sell your flat, the CPF you used (plus accrued interest) goes back into your CPF account.
- If you're 55 or older when that happens, CPF first uses the refund to top up your Retirement Account to your Full Retirement Sum ($220,400 if you turn 55 in 2026). Only what's left is free to use.
- In my example, the same flat sold at the same price leaves you about $60,000 less cash if you sell after 55 instead of before.
- Plan early: the timing of your sale, a property pledge, and the Silver Housing Bonus can all change your numbers.
Where your sale money goes
When you sell an HDB flat, the money comes out in a fixed order:
- Your outstanding loan is paid off first.
- Your CPF refund goes back into your CPF account: every dollar of CPF you used for the flat (down payment, monthly instalments, stamp duty and fees), plus the interest it would have earned had it stayed in CPF ("accrued interest").
- Whatever is left is paid to you in cash.
You can see your exact CPF refund on CPF's Home Ownership Dashboard, and my sale proceeds calculator puts all three together.
The example
Let's set up a real scenario, using numbers that are common for a lot of HDB owners today:
| Your flat is worth | $550,000 |
|---|---|
| Outstanding loan | − $150,000 |
| CPF used over the years, refunded to your CPF when you sell | − $250,000 |
| Cash from the sale | $150,000 |
| Already in your CPF | $50,000 Ordinary Account, $50,000 Special Account |
| Your next home | A 3-room flat for $350,000 |
Here's where it gets interesting: what you do next, and when you do it, changes everything. Same flat, same sale price, same next flat. The only difference between the two scenarios below is whether you sell and buy before or after you turn 55.
Scenario 1: you sell and buy before 55
For the $350,000 flat, you can fully use your CPF refund of $250,000 plus the $50,000 already in your Ordinary Account. Together that's $300,000 of CPF towards the purchase, leaving a $50,000 gap that you top up in cash. But remember, you walked away with $150,000 in cash from the sale.
Result: $100,000 in cash left over, and your Special Account untouched at $50,000.
Scenario 2: you sell and buy after 55
This is the part most people don't know about, and the whole reason this guide exists. If you sell after you turn 55, everything changes, and it comes down to one thing: your Full Retirement Sum (FRS). When you turn 55, CPF sets a target for how much you should have in your new Retirement Account. If you turn 55 in 2026, that target is $220,400, and it's set higher for each later year's cohort.
- The moment you turn 55, CPF doesn't wait for you to do anything. Your Ordinary and Special Account savings ($50,000 + $50,000) are moved into your Retirement Account. That's $100,000, so you're $120,400 short of the FRS.
- When you sell, your $250,000 CPF refund isn't yours to use freely yet. CPF first uses it to close that $120,400 gap, which leaves $129,600 of the refund. Compared with the $250,000 you had to work with before 55, you've lost over $120,000 of usable funds before you've even looked at a new flat.
- With your $150,000 of cash, that's $279,600 in total, compared with $400,000 ($150,000 cash plus $250,000 CPF) before 55.
- For the new flat, there's another rule: you can use only up to half of your FRS from your Retirement Account towards the purchase, $110,200 in this example. Take that off the $350,000 price, and $239,800 still has to be paid out of your $279,600.
Result: $39,800 left over.
Side by side
| Sell before 55 | Sell after 55 | |
|---|---|---|
| CPF refund you can use freely | $250,000 | $129,600 |
| Total funds for the next home | $400,000 | $279,600 |
| Cash left after buying the $350,000 flat | $100,000 | $39,800 |
Same flat, same sale price, same purchase. The only thing that changed is your age when you did it, and that one factor costs about $60,000 in cash you'd otherwise be holding. Your own numbers will look different, because your flat's value, your loan and your CPF balances are different, but the principle stays the same: timing your sale around your 55th birthday changes how much cash you walk away with. It isn't just a date on the calendar, and it's the mistake I see people make all the time.
Why CPF does this
It isn't a penalty. Your Retirement Account is what pays you a monthly income for life through CPF LIFE, from your payout age (65 for most people). The FRS is the amount CPF wants set aside at 55 so that income is enough. The money CPF holds back isn't lost: it's still yours, just paid out monthly in retirement instead of being available as cash today.
CPF's own rule is that if you're 55 or older, your housing refund is first used to top up your Retirement Account to your retirement sum. Any balance after that stays in your Ordinary Account, where you can use it for your next home or, from 55, withdraw it in cash.
Where the $110,200 comes from
When you're 55 or older and right-sizing to a 3-room or smaller HDB flat, CPF lets you use the part of your Retirement Account refund that's above your Basic Retirement Sum (BRS, half the FRS: $110,200 for 2026) towards the new flat, as long as:
- you buy the new flat within three years of selling your old home;
- the new flat costs less than the price you sold your old home for; and
- you haven't yet been put on a CPF LIFE plan.
How much CPF you can use for any purchase after 55 also depends on the remaining lease of the flat you buy: CPF wants the lease to cover the youngest buyer to at least age 95 for full use. Check your own case with CPF before you commit.
The 2026 retirement sums
| If you turn 55 in 2026 | Amount | What it means |
|---|---|---|
| Basic Retirement Sum (BRS) | $110,200 | The amount you can keep in your Retirement Account if you own a property with a long enough lease and pledge it |
| Full Retirement Sum (FRS) | $220,400 | The target CPF tops up to first, including from your housing refund |
| Enhanced Retirement Sum (ERS) | $440,800 | The most you can put into your Retirement Account, for higher monthly payouts |
Your retirement sums are fixed in the year you turn 55. Each later cohort's sums are higher.
Why this matters
This isn't just a number on a slide. I've seen it play out in real life more than once. Some owners end up unable to cash out at all, because their sale turns out negative: what they owe wipes out what they can take back. Others can't fully pay for the smaller home they want, because the numbers just don't stretch far enough. The worst case is getting stuck, unable to move forward, at exactly the point in life when you should be settling into retirement, not stressing over CPF shortfalls.
Five ways to plan around it
- Do the math before 55. If you already plan to right-size in the next few years, compare selling before and after your 55th birthday with your own numbers. The refund goes back to CPF when the sale completes, so plan around the completion date, not just when you decide to sell, and check the timing with CPF.
- Know your four numbers. Your flat's likely price, your outstanding loan, your CPF refund (from the Home Ownership Dashboard) and your Retirement Account balance against your FRS. With those, you can see exactly how much cash you'll have.
- Check the Silver Housing Bonus. If at least one owner is a Singapore citizen aged 55 or above and you right-size to a 3-room or smaller flat, you may get a cash bonus of up to $30,000 (plus $10,000 more for a 2-room or smaller flat) for committing up to $60,000 to your Retirement Account and joining CPF LIFE. Since 1 December 2025, your CPF housing refund can count towards that commitment, so the top-up in scenario 2 may help you qualify. There are eligibility conditions, such as income, so check with HDB.
- Ask CPF about a property pledge. If you own a property with a long enough lease, you can pledge it at 55 and set aside only the BRS instead of the FRS. It changes what you need to refund later, so understand the trade-off first.
- Keep a buffer. Don't plan to spend every dollar of cash on the next flat. Leave room for renovation, moving, a gap in timing between selling and buying, and your own retirement.
If you'd rather stay in your flat, HDB's Lease Buyback Scheme lets you sell part of your remaining lease back to HDB for retirement income instead. It's a different route, and worth comparing.
If you're in your 50s, or approaching them, and thinking about your next property move, don't wait until it's too late to plan around this. Every situation is different, because your CPF balances, your flat's value and your timeline are different, and they all change the outcome. Before 55 you still have room to plan; after 55 a lot of that flexibility disappears. The best time to figure out your numbers is now, while you still have options.
I can go through your own numbers with you in a property health check, so you don't end up finding out the hard way.

Questions people ask me
If I sell after 55, do I lose the CPF money that tops up my Retirement Account?
No. It stays yours and pays you a monthly income through CPF LIFE from your payout age. You just can't use it as cash or for your next home now.
Can I take my CPF refund out in cash after 55?
Only what's left after your Retirement Account is topped up to your required retirement sum. That balance can stay in your Ordinary Account for your next home, or be withdrawn in cash.
I'm already 55. Is it too late?
Not at all, but the numbers work differently. Check how much you can use for your next home, whether a property pledge or the Silver Housing Bonus applies to you, and leave a buffer.
What is the Full Retirement Sum in 2026?
$220,400 for members turning 55 in 2026. The Basic Retirement Sum is $110,200 and the Enhanced Retirement Sum is $440,800.
Does this only apply to HDB flats?
No: CPF refunds work the same way when you sell a private property you bought with CPF. The example uses an HDB flat because that's where most right-sizing happens.
