HDB Sale Proceeds Estimator — How Much Cash You Actually Walk Away With
Everyone knows their HDB's market value. Almost nobody knows how much cash they'll actually pocket after the sale. Here's the formula and three worked examples.
Answer: Your cash-in-hand = sale price − outstanding loan − CPF refund (principal + accrued interest at 2.5% p.a.) − agent commission (2%) − unrecovered renovation costs. On a $600,000 HDB with $180,000 loan outstanding and $153,000 CPF refund, you walk away with roughly $250,000 cash and $153,000 back in your CPF OA.
The Formula
Cash in hand = Sale Price
− Outstanding HDB/Bank Loan
− CPF Principal Used
− CPF Accrued Interest (2.5% p.a.)
− Agent Commission (typically 2%)
− Unrecovered Renovation / Misc Costs
The CPF refund (principal + accrued interest) goes back into your CPF OA — not into your pocket. This is the part that surprises most sellers. The refunded CPF can be used for your next property purchase.
Worked Examples
Assumptions: $180,000 loan outstanding, $120,000 CPF principal used over ~10 years, $33,000 accrued interest, $5,000 misc costs
| Item | $500,000 Sale | $600,000 Sale | $700,000 Sale |
|---|---|---|---|
| Sale price | $500,000 | $600,000 | $700,000 |
| − Outstanding loan | $180,000 | $180,000 | $180,000 |
| − CPF principal refund | $120,000 | $120,000 | $120,000 |
| − CPF accrued interest | $33,000 | $33,000 | $33,000 |
| − Agent commission (2%) | $10,000 | $12,000 | $14,000 |
| − Misc / reno writeoff | $5,000 | $5,000 | $5,000 |
| Cash in hand | $152,000 | $250,000 | $348,000 |
| CPF OA refund | $153,000 | $153,000 | $153,000 |
The CPF OA refund ($153,000) is not cash you can spend freely — it goes back into your CPF account. But you can use it for your next property.
CPF Accrued Interest — The Hidden Cost
This is the number that catches most sellers off guard. The longer you've owned, the more accrued interest you owe back to CPF. Here's how it grows on $120,000 of CPF usage:
| Years Owned | CPF Principal | Accrued Interest (2.5%) | Total CPF Refund |
|---|---|---|---|
| 5 years | $120,000 | $15,600 | $135,600 |
| 10 years | $120,000 | $33,600 | $153,600 |
| 15 years | $120,000 | $54,600 | $174,600 |
| 20 years | $120,000 | $79,200 | $199,200 |
Simplified calculation assumes all CPF was used at point of purchase. In reality, CPF is drawn down progressively (monthly mortgage payments), so actual accrued interest may differ. Check CPF portal for your exact figure.
Agent Commission
The standard HDB seller agent commission is 2% of sale price. Some agents charge 1.5% for higher-value flats. This comes out of your sale proceeds.
| Sale Price | Commission (2%) | Commission (1.5%) |
|---|---|---|
| $500,000 | $10,000 | $7,500 |
| $600,000 | $12,000 | $9,000 |
| $700,000 | $14,000 | $10,500 |
| $800,000 | $16,000 | $12,000 |
Commission is negotiable. Always confirm the rate before signing the exclusive agency agreement.
Where Your Proceeds Go
After selling your HDB, you have two pools of money:
Cash in hand
This is yours to use freely. Most upgraders put it toward the down payment on their next property. You can also invest it, hold it, or use it for renovation. No restrictions.
CPF OA refund
Goes back into your CPF Ordinary Account. You can use it for the next property purchase (down payment, stamp duty, monthly mortgage). You cannot withdraw this as cash until age 55 (subject to BRS/FRS rules).

FAQ
What is CPF accrued interest and why does it reduce my cash proceeds?
CPF accrued interest is the 2.5% per annum interest you would have earned if the CPF money had stayed in your OA instead of being used for your HDB. When you sell, you must refund the principal + accrued interest to your CPF OA. This is mandatory — you cannot take it as cash. After 10 years, accrued interest on $120K of CPF usage is roughly $32K–$35K.
Do I have to pay agent commission when selling HDB?
You are not legally required to use an agent, but most HDB sellers do. The standard commission is 2% of the sale price. On a $600K HDB, that is $12,000. If you sell without an agent (DIY), you save this cost but handle all viewings, negotiations, and paperwork yourself.
Can I keep the cash proceeds from my HDB sale?
Yes — after the CPF refund, loan repayment, and fees are deducted, the remaining cash is yours. You can use it for your next property down payment, invest it, or keep it in the bank. There is no restriction on how you use the cash portion.
What happens to my HDB grants when I sell?
CPF housing grants (like the Enhanced CPF Housing Grant) are treated the same as CPF usage. The grant amount plus accrued interest at 2.5% p.a. must be refunded to your CPF OA when you sell. This reduces your cash proceeds and increases your CPF OA balance.
How do I find out my exact CPF usage and accrued interest?
Log in to the CPF website (cpf.gov.sg) with Singpass, go to My CPF > Home Ownership > Property. It shows the total CPF principal used and the accrued interest to date. This is the exact amount that will be refunded to your OA upon sale.
Does renovation cost affect my sale proceeds?
Renovation is a sunk cost — it does not get refunded. But it indirectly affects your proceeds because it reduces your net gain. If you spent $40K on renovation and it increased your sale price by $20K, you effectively lost $20K. Most renovations do not recover their full cost at resale.
