This is the one that ambushes people. I’ve watched it happen across a table more than once, and it’s never fun to be the one saying it.

Say you sell your flat for $650,000. Round number, just for the example. In your head, that’s $650,000. That’s the condo deposit. That’s the plan you’ve been carrying around for two years.

Then reality lines up to take its cut.

First the loan. Then CPF wants its money back.

The outstanding loan comes off the top. Fine, you expected that one.

Then your CPF has to be refunded. And not just what you took out. You also put back the accrued interest on top: the interest that money would have earned if you’d left it sitting in your CPF and never touched it.

That rate is 2.5% a year, and it compounds. Quietly. The entire time you’ve lived there.

What that actually looks like

Suppose you used $200,000 of your CPF for the flat, and you’ve been there ten years. At 2.5% compounding, that’s roughly $56,000 of accrued interest you have to return to your CPF when you sell.

Now, that money isn’t gone. It’s yours. But here’s the catch that trips people up: it goes back into your CPF, not into your bank account for the next place. So the cash that actually lands in your hands is a good deal smaller than the $650,000 you’d been picturing.

Don’t get me wrong; this isn’t a loss. It’s your own money, moved to your own account. But if you’ve been planning your next move as though the full sale price is cash in hand, that gap is where the plan quietly breaks.

Run it before the showflat, not after

Do this number now, while it’s still just arithmetic. Loan, CPF refund, accrued interest, then what’s left. Because the worst time to find out what you actually walk away with is after you’ve fallen in love with a place you now can’t quite afford.
