What Does It Mean?

CPF accrued interest is the interest that would have been earned on CPF funds used for property purchase, had the money remained in the CPF OA (currently 2.5% per annum). This amount must be refunded to CPF when the property is sold.

How Is It Calculated?

Accrued Interest = CPF Used × (1 + 2.5%)Years − CPF Used
Formula

The 2.5% interest compounds annually. After 10 years, $200,000 of CPF used accumulates ~$56,000 in accrued interest.

Worked Example

Suppose you use $250,000 from your CPF OA towards a property and hold it for 15 years before selling, with CPF OA earning 2.5% per annum:

$250,000
CPF Principal Used
~$112,000
Accrued Interest (15 yrs)
~$362,000
Total Refund to CPF on Sale

The $362,000 goes back into your CPF OA (not your pocket) when you sell. If the sale proceeds cannot cover the full refund, the shortfall is generally waived — but any cash profit is reduced by whatever you must return. This is why using more CPF up front can leave you "asset rich, cash poor" at resale.

Why It Matters

CPF accrued interest is the silent cost of using CPF for property. At 2.5% compounding, the amount you must refund to CPF on sale can dwarf the principal after two decades — leaving sellers "asset rich, cash poor" if their sale price barely covers the refund.

Frequently Asked Questions

What interest rate applies to CPF accrued interest?
The current CPF Ordinary Account rate of 2.5% per annum, compounded, is applied to the CPF amount you used for the property.
Do I lose money to accrued interest?
Not exactly — the refund goes back into your CPF (earning interest for retirement), not to the government. But it reduces the cash you walk away with at sale.
