# HDB Sale Proceeds Calculator: Cash, CPF Refund and Resale Timeline Work out the cash you keep from selling your HDB flat: price less loan, CPF refund with 2.5% accrued interest, resale levy, agent and legal fees. Interactive tool: https://lookup.sg/tools/hdb-sale-proceeds-calculator ## How this works When you sell, the price first repays your outstanding housing loan. What is left goes back to each owner's CPF Ordinary Account: the CPF principal you used for the flat (downpayment, monthly instalments, stamp duty and legal fees) plus accrued interest. Only the balance after that is paid to you in cash. Accrued interest is the interest your CPF would have earned had it stayed in the Ordinary Account: 2.5% a year, computed monthly and compounded yearly. It runs from each withdrawal until the sale, which is why the refund can be far larger than the CPF you used. If you sell at market value and the proceeds are not enough to refund everything, you do not have to top up the shortfall in cash. From the cash, deduct the resale levy if HDB is collecting it from this sale (you are buying a second subsidised flat and collected its keys first), the subsidy recovery on a Plus or Prime flat bought from HDB, your agent's commission (negotiable, plus 9% GST if the agency is GST-registered) and legal fees. HDB's own conveyancing fee is about S$0.45 per S$1,000 above the first S$60,000. Timeline: register an Intent to Sell, wait 7 days, then grant an Option to Purchase, which the buyer has 21 calendar days to exercise. Resale completion is about 8 weeks after HDB accepts the resale application. Cash is credited the next working day and the CPF refund within 7 to 14 working days. ## FAQs ### How much CPF do I need to refund when I sell my HDB flat? All the CPF principal used for the flat plus accrued interest at 2.5% a year. For example, S$100,000 used upfront and left for 10 years becomes a refund of about S$128,000. ### What if my sale proceeds are not enough to refund my CPF? If you sell at market value, CPF Board does not require you to top up the shortfall in cash. You still receive no cash proceeds, because everything after the loan goes back to CPF. ### How long does it take to sell an HDB flat? About 8 weeks from HDB accepting the resale application to completion, after a 7-day wait from your Intent to Sell and up to 21 days for the buyer to exercise the Option to Purchase. Allow roughly 3 months end to end once you have a buyer. ### When do I receive the cash from selling my flat? HDB credits the cash proceeds to your bank account by the next working day after resale completion. The CPF refund is made within 7 to 14 working days. ### Is the resale levy deducted from my sale proceeds? Only if you sell this flat after collecting the keys to a second subsidised flat. Then HDB deducts the levy (for example S$40,000 for a 4-room bought as a family) from the net proceeds. If you sell first, you pay the levy in cash at key collection instead. ## Sources - [HDB: Resale flat completion for sellers (proceeds timing)](https://www.hdb.gov.sg/managing-my-home/selling-a-flat/process-for-selling-a-flat/resale-flat-completion) - [HDB: Option to Purchase when selling a flat](https://www.hdb.gov.sg/managing-my-home/selling-a-flat/process-for-selling-a-flat/option-to-purchase) - [HDB: Approval of resale application for sellers (legal fees)](https://www.hdb.gov.sg/managing-my-home/selling-a-flat/process-for-selling-a-flat/resale-flat-application/approval-of-application) - [HDB: Resale levy and subsidy recovery](https://www.hdb.gov.sg/buying-a-flat/bto-sbf-and-open-booking-of-flats/conditions-after-buying-a-new-flat) - [CPF: How CPF interest is computed](https://www.cpf.gov.sg/service/article/how-is-my-cpf-interest-computed-and-credited-into-my-accounts) --- Source: Lookup (https://lookup.sg) · Data as of October 2026 · Listings compiled from Singapore government open data (data.gov.sg), OneMap and Overture Maps places.
