What will your CPF actually refund?

Every dollar of CPF you put into a home keeps earning 2.5% — against you. On sale, you must refund the principal and that accrued interest back to your own CPF. Drag the years and watch the debt to yourself grow.

— What this actually means

"The refund isn't a fee. It's interest you owe yourself — quietly compounding."

Most people treat CPF as free money for the downpayment. It isn't. The moment you draw it out, CPF keeps charging that money 2.5% a year — compounded monthly — and you're the one who has to pay it back on sale.

Hold for ten years and the accrued interest alone can run to six figures. It doesn't vanish; it just moves from your sale proceeds back into your CPF. You keep it — but it's locked, not cash.

The dangerous case is the negative sale: if a soft market means your price barely clears the outstanding loan, there may be nothing left to refund CPF — and the shortfall comes out of your own pocket in cash. That's how a family can sell at what looks like a profit and still need to top up.

"A break-even sale on paper can still leave you writing a cheque to complete it."
