Singapore HDB Sale Proceeds Calculator 2026 — Net Cash After CPF Refund, Outstanding HDB Loan, Agent Commission & 2.5% CPF Accrued Interest for Singapore HDB Flat Sellers

Net cash proceeds = Sale Price − Outstanding Loan − CPF Refund (principal + 2.5% accrued interest) − Agent Commission − Legal Fees − HDB Admin Fee − Seller’s Stamp Duty (if within 3 years) − any other costs. This calculator performs all these deductions automatically. The key inputs to verify are: exact outstanding loan balance (from HDB flat portal or bank), total CPF OA used including grants (from my.cpf.gov.sg via Singpass), and the agreed sale price.

Under Singapore’s CPF rules, any CPF Ordinary Account (OA) funds withdrawn for housing (down payment, monthly mortgage, housing grants) must be refunded to your CPF OA when the property is sold. This is because CPF is a retirement savings fund, and the government requires these funds to be returned to ensure you have adequate retirement savings. The refund includes the principal amount withdrawn plus accrued interest at 2.5% p.a. (the rate your OA would have earned had the money stayed in CPF). The refund goes back into CPF OA, not your bank account.

CPF accrued interest is calculated at 2.5% per annum on the CPF principal withdrawn, compounded from the date of each withdrawal. For a simplified estimate, this calculator applies 2.5% compound interest to the total CPF used over the full holding period. The exact amount is determined by CPF Board based on the precise date and amount of each CPF withdrawal. For example: S$200,000 CPF used over 10 years accrues approximately S$56,250 in interest, meaning S$256,250 total must be refunded to CPF OA. Check your exact amount at my.cpf.gov.sg.

Cash proceeds are the net amount transferred to your bank account after all deductions. CPF refund is the amount returned to your CPF Ordinary Account — it is not cash you can spend freely. The CPF refund can only be used for another property purchase (using CPF OA) or remains locked in CPF for retirement (earning 2.5% interest). If you need cash for your next property down payment or renovation, you must plan your cash proceeds carefully, as the CPF OA refund, while large, has restricted usage compared to direct cash.

Singapore HDB resale agent commission for sellers is typically 2% of the sale price (for a sole agent) or can be negotiated to 1% if you are also buying through the same agent or if the market is slow. For a S$600,000 flat, 2% commission = S$12,000 (plus GST at 9%). There is no fixed legal rate — it is negotiable. Some sellers opt for a co-broking arrangement (1% to buyer’s agent, 1% to seller’s agent) or direct HDB resale via the HDB Resale Portal without agent commission, though this requires more administrative effort from the seller.

Seller’s legal fees for an HDB resale flat typically range from S$1,500 to S$3,000 for conveyancing, including: resale checklist endorsement, Option to Purchase legal review, completion documentation, and CPF discharge. The exact amount varies by law firm. Some sellers opt for HDB’s in-house legal service (HDB’s appointed lawyers) which can be slightly cheaper. HDB also charges a resale administrative fee: S$80 for 3-room and below, S$40 for 4-room and above (buyer pays some components too). Allocate S$2,500–3,500 as a conservative estimate for total legal and admin costs.

Seller’s Stamp Duty (SSD) applies if you sell your HDB flat within 3 years of the purchase date (date of Option to Purchase exercise). The SSD rates for HDB are: Year 1 (within first year): 12% of sale price; Year 2 (between 1 and 2 years): 8%; Year 3 (between 2 and 3 years): 4%. After 3 years, no SSD applies. Note: the HDB Minimum Occupation Period (MOP) is 5 years, which means you cannot even sell most HDB flats within the 5-year MOP. However, in special cases (financial hardship, divorce, etc.) where HDB approves an early sale, SSD would apply if within 3 years.

The housing grants (EHG, CHG, PHG) are credited to your CPF OA and used for housing. When you sell, these grant amounts are included in the CPF OA refund calculation — the principal grant amount plus the 2.5% p.a. accrued interest since the grant was received must be returned to CPF OA. The grants do not go back to HDB — they return to your CPF OA. You do not pay them back in cash. However, after MOP, if you buy another HDB resale flat using CPF OA, the returned grant funds (now in your CPF OA) can be used again.

The Minimum Occupation Period (MOP) is the minimum period you must physically occupy your HDB flat before you can sell it on the open market. For most HDB flats, the MOP is 5 years from the date you collected the keys (or the date of legal completion for resale). Prime Location Public Housing (PLH) flats have a 10-year MOP. During the MOP, you cannot sell the flat, rent out the entire flat, or buy a private property in Singapore. After MOP, you are free to sell, and you also become eligible to buy a private property if you wish to upgrade.

You can sell your HDB flat even if the CPF refund (principal + accrued interest) exceeds the net sale price after loan repayment. However, in this scenario, you will have negative cash proceeds and must top up the shortfall in cash. CPF Board will refund only up to the actual cash received (after loan repayment) to your CPF OA — any balance that cannot be returned due to insufficient proceeds is treated differently under CPF rules. In cases of hardship, CPF Board may exercise discretion on accrued interest. Consult HDB and CPF Board directly if you are in this situation.

Negative cash proceeds occur when the sale price is insufficient to cover: (1) outstanding loan balance + (2) CPF refund (principal + 2.5% accrued interest) + (3) selling costs. This is most common for sellers who: used a large CPF OA amount for a flat that hasn’t appreciated much; sold after many years with large compounded CPF interest; bought at a peak price with a large loan; or used significant housing grants that also accrue interest. Modelling proceeds before accepting an offer is essential to avoid being surprised at completion.

Your outstanding HDB concessionary loan or bank mortgage loan must be fully repaid from the sale proceeds before you receive any cash. The outstanding balance is deducted before CPF refund. If your loan balance is large relative to the sale price, your net cash could be very low or negative even before the CPF refund is deducted. Get your outstanding loan balance from MyHDBPage (for HDB loans) or your bank’s internet banking / statement (for bank loans) to get an accurate figure for this calculator.

No. Capital gains from selling your HDB flat or private residential property are not subject to income tax in Singapore, as Singapore does not have a capital gains tax. The only “sale tax” is the Seller’s Stamp Duty (SSD) — which applies to HDB sales within 3 years and private property within 3 years. After the respective holding periods, you pay no additional tax on the sale profit itself. However, rental income from the flat before sale is taxable as income. For non-residents selling Singapore property, withholding tax rules may apply — consult IRAS.

When you sell your HDB, the CPF refund (principal + accrued interest) returns to your CPF OA. You can immediately use this CPF OA balance towards your next private property purchase — for the 5% down payment (CPF can cover the 20% CPF+cash down payment component), monthly mortgage repayments, and stamp duties if using CPF is permitted. There is typically a 1–3 month delay between HDB completion and when the CPF refund shows in your account. Plan your condo purchase timing accordingly, as you may need bridging cash before the CPF refund arrives.

Log in to my.cpf.gov.sg using your Singpass. Navigate to “My Dashboards” → “Property” → “My Properties.” This shows a detailed breakdown of: total CPF withdrawn for each property, the breakdown by year, and the current accrued interest amount. You can also use CPF’s housing calculator to project the refund at different sale dates. This is the most accurate source — always use this figure rather than estimating, as the actual accrued interest depends on the precise dates and amounts of each CPF withdrawal over your ownership period.

The typical Singapore HDB resale timeline after agreeing on a price: Day 1: Grant Option to Purchase (OTP) to buyer. Day 1–21: Buyer exercises OTP. Week 3–4: Submit HDB resale application online (both parties). Week 4–8: HDB processes application, buyer arranges HDB/bank loan. Week 8–12: HDB approval letter issued, completion appointment scheduled. Week 12–14: Completion appointment at HDB Hub — loan repaid, CPF refund processed, net cash disbursed. Total: approximately 8–12 weeks from OTP grant to completion. CPF OA refund typically appears 1–2 weeks after completion.
