Key Takeaways
- • CPF accrued interest is charged at 2.5% a year, compounding, on CPF OA used for a property.
- • On a sale, CPF principal plus accrued interest is returned to your CPF before you see cash proceeds.
- • Compounding makes the bill grow sharply with holding period -- it roughly doubles over about 28 years.
- • The refunded money is yours -- it returns to your CPF account, it is not lost -- but it reduces cash in hand.
- • In a low-price-growth scenario, accrued interest can turn an apparent paper gain into thin or negative cash.
Every CPF dollar you use for a property carries a quiet tag: 2.5% a year, compounding. It does not show up on a statement you check monthly. It surfaces at one moment -- the day you sell -- and it surprises people every time.
This piece does the maths plainly, with worked examples over 5, 10 and 20 years, so you can see the shape of the bill before it arrives.
What is CPF accrued interest, and why does it exist?
When you take money out of your CPF Ordinary Account to buy a home, that money stops earning the 2.5% it would have earned sitting in the OA. According to the CPF Board, to make your retirement savings whole, the CPF system charges "accrued interest" -- the interest your CPF would have earned had you not used it.
That accrued interest accumulates at 2.5% a year and compounds. When you sell the property, you must return to your CPF account both the principal you used and all the accrued interest. Only after that return is settled do you receive your cash proceeds.
It is important to be clear: accrued interest is not a fine or a fee paid to the government. It is your own money, returning to your own CPF account, restoring the retirement balance you drew down. But for cash-in-hand purposes, it behaves like a deduction from your sale.
How fast does the bill grow? Worked examples
The single most useful thing to understand is how compounding stretches the number over time. The table below shows CPF principal used, grown at 2.5% compounding, at three holding periods. Figures are rounded.
| CPF OA used | After 5 years | After 10 years | After 20 years |
|---|---|---|---|
| $100,000 | ~$113,000 | ~$128,000 | ~$164,000 |
| $200,000 | ~$226,000 | ~$256,000 | ~$328,000 |
| $300,000 | ~$339,000 | ~$384,000 | ~$491,000 |
| $400,000 | ~$452,000 | ~$512,000 | ~$655,000 |
Illustrative. Assumes a single lump of CPF compounding at 2.5%/yr from purchase. In reality CPF is used progressively over the loan, so the actual accrued total differs -- confirm your exact figure with the CPF Board.
Two things stand out. First, the bill never shrinks -- it only grows. Second, the growth accelerates: over a 20-year hold, $300,000 of CPF used carries roughly $191,000 of accrued interest on top. At a 2.5% compounding rate, the amount roughly doubles every 28 years.
How does accrued interest shrink your net sale proceeds?
Net cash from a property sale is, roughly:
The CPF refund line is the one buyers forget. Consider a stylised example. You bought a property, used $250,000 of CPF over a 10-year hold (so accrued interest brings the CPF refund to roughly $320,000), and the outstanding loan at sale is $600,000. If you sell for $1.4M:
| Line | Amount |
|---|---|
| Sale price | $1,400,000 |
| Less: outstanding loan | −$600,000 |
| Less: CPF refund (principal + accrued interest) | −$320,000 |
| Less: agent commission and legal costs (illustrative) | −$30,000 |
| Cash in hand | ~$450,000 |
Illustrative only -- figures are placeholders to show the structure, not a market estimate. Selling costs vary; SSD applies if sold within the holding-period window.
The $320,000 returns to your CPF account -- it is not lost wealth. But if you were counting on the "$1.4M minus $600,000 loan = $800,000" headline as cash for your next purchase, the real cash figure is $450,000. That gap is what trips up upgraders planning a chain of moves.
What happens if you sell at a loss?
If your sale proceeds are not enough to fully refund the CPF used plus accrued interest, you generally do not have to top up the shortfall in cash, provided the property was sold at or above market value and the loss is genuine. The unrefunded portion is, in effect, absorbed. The detail matters and has conditions -- I cover it in what happens to your CPF if you sell at a loss.
Can you reduce your accrued-interest bill?
You cannot change the 2.5% rate or the compounding. But you can influence how large the bill grows:
- Use less CPF. Paying more of the purchase and instalments in cash means less CPF principal, so less accrued interest. See cash vs CPF for the monthly mortgage.
- Make voluntary refunds. You can voluntarily refund CPF used (with accrued interest) back to your OA while still holding the property. This stops further accrual on the refunded amount.
- Mind the holding period. Compounding is time-driven. A shorter hold carries a smaller accrued total -- though selling decisions should be driven by strategy, not just this line.
Winfred's Take
CPF accrued interest is the most under-modelled number in Singapore property. Owners look at "price went up, I made money" and forget that the CPF refund line eats a real share of the cash. I have watched upgraders commit to a new purchase on the strength of a headline gain, then discover the cash they could actually extract was a third smaller once the CPF refund was settled. It is not a reason to fear CPF -- the money returns to you. But every sale-to-buy plan I build for a client puts the CPF refund, with accrued interest, front and centre. Plan with the cash number, not the headline number.

Frequently asked questions
Where can I see my exact accrued interest?
Your CPF account statement shows the principal CPF used for your property and the accrued interest to date. The CPF Board is the authoritative source for your number -- the table in this article is illustrative.
Is accrued interest a tax or penalty?
No. It is the interest your CPF savings would have earned if not used for the property. It returns to your own CPF retirement account on sale. It is restoration of your retirement balance, not a charge to the state.
Does accrued interest apply to HDB and private property?
Yes. Any CPF Ordinary Account money used for either an HDB flat or private property accrues interest at 2.5%, compounding, and must be refunded on sale.
Can I avoid accrued interest by paying with cash?
Paying with cash means you use less CPF, so less accrued interest builds up. You cannot eliminate accrued interest on CPF you have already used, but you can limit future accrual by using cash or making voluntary refunds.
What if I am over 55 when I sell?
The CPF refund rules interact with the Retirement Account from age 55. The refunded CPF is generally directed according to your retirement savings position at the time. Confirm the specifics with the CPF Board, as the rules around age 55 changed in recent years.
A note from Winfred: The worked figures here are illustrative and assume simplified compounding. Your actual accrued interest depends on exactly when each CPF amount was used. For a real sale decision, get your precise figure from your CPF statement or the CPF Board. This article is general guidance, not personal financial advice.
