Of all the costs involved in selling a Singapore property, CPF accrued interest is the one that catches the most people off guard. Not because it's hidden — it's disclosed clearly by the CPF Board — but because it compounds quietly in the background for years, and the full amount only becomes visible at the point of sale.
Understanding it isn't complicated. Planning around it is what makes the difference.
What CPF Accrued Interest Actually Is
When you use CPF funds to buy a property — either for the down payment or for monthly mortgage repayments — those funds leave your CPF Ordinary Account. Had they stayed in your account, they would have earned the CPF OA interest rate, currently 2.5% per annum (with additional interest on the first $60,000).
Accrued interest is the CPF Board's way of accounting for that opportunity cost. It's the interest your withdrawn funds would have earned, calculated from the date of each withdrawal to the date of sale.
When you sell your property, you are required to refund both the principal CPF amount used and the accrued interest back into your CPF accounts before you pocket any cash proceeds.
Why The Numbers Surprise People
The surprise comes from compounding and time. If you bought your property 15 years ago and used $200,000 of CPF, the accrued interest on that amount alone — at 2.5% per annum, compounding — adds up to roughly $85,000. The total refund due to CPF would be around $285,000, not $200,000.
Add in the CPF contributions made monthly toward the mortgage over those same 15 years, each with their own accrued interest, and the total figure can be significantly higher than most homeowners intuitively estimate.
How To Find Your Own Accrued Interest Figure
You can check your CPF accrued interest amount directly through the CPF Board's website by logging in with your Singpass. Under "My Statement," look for the "Properties" section, which shows the total CPF principal withdrawn and the accrued interest to date.
That figure updates periodically. For planning purposes, it's worth checking it annually — and always before making any decision about selling or upgrading.
A proper financial roadmap for any property move starts with this number. Everything else — what you can afford to upgrade to, how much cash you'll have, whether the timing makes sense — flows from there.
