CPF Refund and Accrued Interest: Why the Sale Price Isn't What Hits Your Bank
Sell for $680,000 and you don't get $680,000. Your loan, your CPF refund with accrued interest, and costs come out first. Here's the order of payments, with a full worked example.
The rule, in plain English
When you bought your home, you probably paid part of it with CPF. Downpayment, monthly instalments, maybe a housing grant, maybe the stamp duties and legal fees. Every one of those dollars came out of your Ordinary Account (OA), and when you sell, every one of them goes back.
Not just the dollars, either. You also refund the interest those dollars would have earned if you'd left them in CPF, charged at 2.5% a year and compounded from each withdrawal date right up to completion day. CPF calls this accrued interest.
Two things to hold in your head at once. First, this isn't a penalty: the refund goes into your own CPF, and you can use it for your next home or your retirement. Second, it isn't cash. It never touches your bank account. And that's why "sold for $680,000" and "I have $680,000" are two very different sentences.
What counts toward the refund:
- CPF used for the downpayment
- CPF used for monthly instalments over the years
- Housing grants (they were CPF monies credited to your OA)
- Stamp duties and legal fees paid with CPF
- Each with its own accrued interest, from the date it left your OA
The order of payments on completion
On completion day, your sale proceeds get spent in a fixed order. You don't choose the sequence:
- The outstanding loan — HDB or bank — is paid off first.
- The CPF refunds come next: principal plus accrued interest, for each owner. Note that the option fees your buyer paid count as part of the proceeds here.
- The costs of selling: legal fees, agent commission, any resale levy if you're a second-timer.
- Whatever is left is your cash. This is the only line that reaches your bank account.
If you're 55 or older, one more step: the refund first tops up your Retirement Account to the Full Retirement Sum, and only the balance stays in your OA.
Worked example: a $680,000 sale
Say you bought a resale flat in 2017. Over nine years you used $240,000 of CPF: downpayment, instalments, and a grant. The accrued interest on that, at 2.5% a year compounded, comes to roughly $59,700. Now you sell for $680,000 in 2026:
Worked example at CPF OA rate 2.5% p.a., compounded · Computed 17 Jul 2026
| Line | Amount | Where it goes |
|---|---|---|
| Sale price | $680,000 | The number on the contract |
| Less: outstanding loan | −$205,000 | To HDB or the bank |
| Less: CPF principal used | −$240,000 | Back to your CPF OA |
| Less: CPF accrued interest (9 yrs) | −$59,700 | Back to your CPF OA |
| Less: legal + commission (est.) | −$15,000 | Lawyer and agency |
| Net cash to your bank | ≈ $160,300 — about 24 cents in the dollar of the contract price. The $299,700 CPF refund isn't lost; it's back in your CPF for the next place. But it was never cash. | |

Your numbers will differ. Your loan balance, your exact CPF usage, and your sale price all move the result, sometimes by six figures. Which is why this maths belongs at the start of a sale, not at completion.
Negative cash sale: when the maths goes the other way
Sometimes the loan plus the CPF refund adds up to more than the sale price. That's a negative cash sale, and it's more common than people think, especially with flats bought recently with heavy CPF usage.
A quick example. Sell for $750,000. Outstanding loan: $495,000. That leaves $255,000. CPF refund needed: $335,000. Shortfall: $80,000.
Here's the part that matters: if you sold at or above market value, you generally don't have to top up that $80,000 in cash. CPF takes what the proceeds allow after the loan is cleared, and the required refunds are pro-rated. You walk away with zero cash, but not a bill.
Sell below market value, though, and the protection disappears. You may be asked to top up the difference in cash. This is one reason I insist on pricing from transacted sales rather than hopeful numbers: the "market value" line isn't an opinion, it's the boundary between zero cash and owing money.
Before you list, get three numbers
1. Your outstanding loan. One phone call to HDB or your bank, or it's on your latest statement.
2. Your CPF used plus accrued interest. Log in to the CPF website with Singpass; the exact figure, updated monthly, is under your property statement. No guessing needed.
3. A realistic sale price. Built from recent transactions in your block and town, not asking prices. That third number is the one I can give you, free, with the comparables shown: get a home valuation.
With those three numbers you'll know your net position before anyone lists anything. If you're selling to buy next, the sequencing matters just as much as the sums: selling your HDB to upgrade to a condo maps the timeline and the ABSD remission clock.

Common questions
CPF refunds, asked and answered
Yes. Housing grants are credited into your CPF Ordinary Account, so they count as CPF monies used for the flat. The grant amount plus accrued interest must go back into your CPF when you sell, just like your own contributions.
On the sale completion date. The clock runs from each CPF withdrawal you made — downpayment, instalments, grants, stamp duties — right up to the day the sale completes, compounding at 2.5% a year.
If you sold at or above market value, you generally do not have to top up the shortfall in cash. CPF takes what the proceeds allow after the loan is cleared, and the required refunds are pro-rated. Note that option fees you received count as part of the proceeds. Sell below market value, though, and you may be asked to top up the difference.
Yes. The refund first tops up your Retirement Account to the Full Retirement Sum. Whatever is left after that stays in your Ordinary Account. If you pledged your property toward your retirement sum, that pledged amount must also be refunded.
Yes. Once the refund lands back in your Ordinary Account, it is available for eligible housing payments on your next purchase: downpayment, stamp duties, and instalments. Many upgraders fund most of their next flat this way. The catch is only when you needed cash specifically, for instance the minimum 5% cash portion on a private purchase.
