Quick Answer
If you’re below 55 years old, Your HDB net proceeds = sale price minus outstanding loan, CPF principal refund plus accrued interest, agent commission, and legal fees. On a $550,000 HDB with a $200,000 loan and $150,000 CPF used, most owners walk away with $80,000–$130,000 in cash — the rest is returned to CPF and reusable for the next purchase. But on a side note, if you’re selling your flat and the completion date of your flat is on your 55th birthday or after, your refunded CPF + Accrued interest will have to go to fulfil your Full Retirement Sum (FRS) before you can you utilise the remaining refunded CPF for your next house.
Introduction
Here is a conversation that plays out in almost every upgrader consultation in Singapore: the homeowner has done the mental arithmetic, subtracted their outstanding loan from their expected sale price, and arrived at a comfortable figure. Then the real breakdown appears on screen, and the cash number is $50,000 to $80,000 lower than expected.
This is not because anything went wrong. It is because the CPF refund — the most significant and consistently misunderstood deduction — was left out of the calculation.
If you are approaching your HDB's Minimum Occupation Period (MOP) and starting to think about upgrading, getting your net proceeds figure right is the single most important number to establish before anything else. It determines your upgrade budget, your financing requirements, and whether a bridging loan will be necessary.
This guide walks through every deduction, with a worked example, so you know exactly what to expect.
What Are the Deductions That Hit Your HDB Sale Proceeds?
Four categories of deduction apply to every HDB resale transaction in Singapore.
-
Outstanding loan repayment Whether you have an HDB concessionary loan or a bank loan, the outstanding balance is settled in full at the point of sale completion. This is straightforward — whatever remains on your loan statement is deducted before you see any proceeds.
-
CPF refund (principal + accrued interest) This is the deduction that catches most sellers off guard. Under CPF Board rules, every dollar you used from your CPF Ordinary Account (OA) for your property purchase — downpayment, monthly instalments, or both — must be returned to your CPF OA when you sell. Crucially, this includes accrued interest at 2.5% per annum, calculated as if those funds had remained in your OA earning interest from the day they were withdrawn.
If you withdrew $120,000 in CPF over 10 years, the accrued interest alone could add $15,000–$20,000 to your refund obligation. The CPF refund does not disappear — it sits in your OA and can be redeployed toward your next property purchase — but it is not cash in your bank account.
-
Agent commission Traditional property agents in Singapore typically charge 1–2% of the sale price for selling an HDB flat. On a $550,000 transaction, that ranges from $5,500 to $11,000.
-
Legal and administrative fees Conveyancing fees for a standard HDB resale sale run approximately $2,000–$3,000 if you’re using a Bank Loan, depending on the law firm. Conversely, if you are using a HDB Loan, you may have the option to engage a HDB Lawyer for your conveyancing and which is much cheaper, typically under $500.
How Much Cash Will I Actually Receive After Selling?
The honest answer: less than most people assume, but the full picture is more useful than the headline number suggests.
Here is a worked example for a 4-room HDB flat in a mature estate:
| Item | Amount |
|---|---|
| Sale price | $600,000 |
| Less: Outstanding HDB loan | -$180,000 |
| Less: CPF refund (principal + accrued interest) | -$165,000 |
| Less: Agent commission (1%) | -$6,000 |
| Less: Legal fees | -$2,500 |
| Cash proceeds (to bank account) | $246,500 |
| CPF refund (to OA — reusable) | $165,000 |
| Total usable funds | $411,500 |
The $165,000 in your CPF OA is genuinely yours — it is available for your condo's downpayment once it clears back into your account, within 21 days after the HDB sale completes. The key distinction is between liquid cash and CPF-locked funds, because condo purchases require a minimum 5% cash downpayment that cannot be paid from CPF.
Can My Net Proceeds Cover a Condo Downpayment?
For most HDB upgraders, the combined cash proceeds and CPF refund are sufficient to cover the 25% downpayment required for a condo purchase — but the split between cash and CPF matters.
A standard condo purchase with a bank loan requires:
Minimum 5% cash (cannot be paid by CPF)
Remaining 20% can be cash or CPF
Up to 75% LTV loan from a bank (subject to TDSR limits)
And something that most buyers forget: The Buyer Stamp Duty (BSD)
On a $1.2 million condo, that means $60,000 in cash minimum. Using the example above, $246,500 in cash proceeds comfortably covers this. The remaining $165,000 in CPF can supplement the 20% balance.
Where timing complications arise: if you are purchasing the condo before your HDB sale completes, your cash and CPF are not yet available. A bridging loan covers this interim period — but it adds financing costs. The cleanest approach for most upgraders is to sell first, then buy.
The Numbers That Surprised My Client
Drawing my experience from one of my recent cases: Client A reached out to us as he was thinking of buying a bigger HDB flat as his children are growing up and they felt they needed more space.When I went through the numbers with them, they were shocked that their CPF has accrued much more interest than they have thought, and that the amount they would have to refund will “eat into” their sales proceeds, thereby limiting their renovation budget. After much contemplation, we suggested for him to hold off his selling process. If he were to sell his flat and discover later that his sales proceeds may not be as much as he thought, it may induce unwarranted stress for Client A.Hence, it is often prudent to have an agent go through the numbers with you once before you make any decision to sell or buy. Especially if you are 55 years and above or are about to hit 55. That is because your Special Account (SA) will be converted to your Retirement Account (RA) and your CPF refund will go to your RA after the sale of your unit if you have not fulfilled your Basic or Full Retirement Sum (FRS).
Here’s also a bonus scenario for you to ponder: After deducting the outstanding bank loan from your sale price, what if the CPF + Accrued interest is more than what remains? In this case, it will be considered a Negative Sale but this is a topic for another day!
How HomeUp Approaches This
At HomeUP, we run your personal net proceeds calculation at the very start of the planning call and potential payments like BSD which most buyers may forget— before we discuss condo budgets, timelines, or any listing strategy. The number tells us everything: how much flexibility you have, whether a simultaneous sell-buy is feasible, and what price band of condo is realistic given your current equity.
This matters because most upgraders approach the process with a condo in mind first and the HDB sale second. That creates misaligned expectations. We work backwards — establish your real proceeds, then identify the condo you can genuinely afford, then build the timeline around it.
On fees: HomeUP charges a fixed $1,999 to sell your HDB — not a percentage of your sale price. On a $600,000 sale, a 1% traditional commission would cost $6,000. You save $4,001. On a $700,000 flat, you save $5,001. That saving goes directly into your upgrade fund, not your agent's pocket.
Our agents are CEA-licensed and operate on a coordinated sell-buy model. We handle both transactions — your HDB exit and your condo entry — as a single, sequenced process, not two separate engagements with two different agents pulling in different directions.
Your upgrade plan is only as good as the numbers underneath it. Before you attend a single showflat launch or speak to a bank about financing, get your net proceeds figure confirmed by someone who can run the full calculation.

FAQ
Does the CPF accrued interest refund mean I lose money?
No. The accrued interest goes back into your CPF OA — it increases your CPF balance. You can use it for your next property purchase. The "loss" feeling comes from expecting cash and receiving CPF instead.
When does the CPF refund hit my account after selling?
CPF Board typically processes the refund within 10–14 working days after the HDB sale is completed. You cannot use these funds for your condo purchase until they have cleared into your OA.
Can I avoid the CPF refund by not using CPF for my next purchase?
No — the refund obligation exists regardless of what you do next. It is triggered by the sale of the property that CPF was used to purchase.
What if I have both an HDB loan and CPF usage — which gets settled first?
Both are settled at completion. The sale proceeds are used to repay the outstanding loan, and separately, the CPF Board is notified to receive the CPF refund amount from the proceeds.
How accurate is a HomeUP net proceeds estimate?
We use your actual outstanding loan balance, CPF statement figures, and current market valuation. It is as accurate as the numbers you provide. The only variable is the final sale price, which we advise on based on comparable transacted prices.
