CPF accrued interest: what HDB sellers must repay

By Winfred Quek · 8 minute read · Last reviewed 27 Aug 2026

Quick answer: When you sell your HDB flat, you must repay the total amount withdrawn from CPF (for downpayment, mortgage instalments, and fees) plus accrued interest. Accrued interest is interest CPF Board credits to your Ordinary Account from the date of withdrawal until the sale completion date. On a SGD 200,000 CPF withdrawal over 20 years, accrued interest is approximately SGD 50,000 to 80,000, depending on interest rates. You can manage this by calculating early, planning your sale timing, or retaining more of your sale proceeds.

Rates and thresholds change. The current figures are kept in one place: the Singapore property rules reference.

Key Takeaways

According to CPF Board, accrued interest is credited to your OA at the statutory interest rate (currently 2.5% per annum) from the withdrawal date until the sale completion date.
On sale, you must repay the entire CPF amount withdrawn plus the accrued interest. This is a non-negotiable obligation; your sale proceeds are reduced dollar for dollar.
The longer you hold your HDB flat after taking a CPF withdrawal, the higher the accrued interest. A 20 year hold accumulates significant interest, often SGD 50,000 to 100,000 or more.
You can request a CPF repayment quotation from CPF Board 1 to 2 months before your intended sale date. The quotation is valid for 30 days and locks in the repayment amount.
Some sellers use the Voluntary Withdrawal (VW) scheme to repay CPF early and reduce accrued interest, but only if they have sufficient liquid savings outside CPF.

CPF accrued interest surprises most HDB sellers because they underestimate how much interest compounds over 15 to 25 years. Understanding the mechanics and planning your repayment is critical to maximizing your net sale proceeds.

How CPF accrued interest works

When you buy an HDB flat, you withdraw from your Ordinary Account (OA) to pay downpayment, mortgage instalments, and stamp duty. CPF Board credits interest to your OA at 2.5% per annum. This interest accumulates until you sell the flat, at which point you must repay both the original withdrawal and all accumulated interest.

Example: You buy a flat in 2005 and withdraw SGD 150,000 from CPF. By 2025 (20 years later), interest at 2.5% per annum compounds to approximately SGD 40,000. On sale in 2025, you repay SGD 150,000 plus SGD 40,000 = SGD 190,000 total. Your sale proceeds are reduced by SGD 190,000 before you receive any net balance.

Repayment mechanics on sale

On the sale completion date, your lawyer holds the sale proceeds and deducts several items before crediting you: (1) CPF repayment (withdrawal plus accrued interest), (2) stamp duty paid by you, (3) agent commission, (4) legal fees, and (5) any outstanding mortgage balance. What remains is your net cash proceeds.

The CPF repayment is deducted first, before other costs. If your sale price is SGD 500,000 and your CPF repayment is SGD 200,000, your proceeds are immediately reduced to SGD 300,000 (before agent commission, stamp duty, and fees).

Calculating your CPF repayment

You can request a CPF Repayment Quotation from CPF Board. Contact them online via their portal or phone 6225 5555. Provide your flat details, property valuation, and intended sale date. CPF Board will calculate the exact amount you must repay, including accrued interest up to your sale completion date.

Request the quotation 1 to 2 months before you intend to sell. The quotation is valid for 30 days. If your sale completes within that 30 day window, the quoted amount holds. If you sell after 30 days, you need a new quotation.

Step 1: Get your CPF balance statement. Log into CPF Board's online portal and download your statement showing total OA withdrawal over the years.

Step 2: Request a repayment quotation. Call CPF Board or use their online form. Provide the property address and your intended sale completion date (typically 8 to 12 weeks from now).

Step 3: Review the quotation. The quotation shows the original withdrawal amount, accrued interest calculated to the expected completion date, and total repayment.

Step 4: Factor into your sale price. If your quotation is SGD 250,000, ensure your sale price accounts for this repayment before calculating your net proceeds. A sale at SGD 500,000 minus SGD 250,000 CPF repayment leaves SGD 250,000 before other costs.

Strategies to minimize accrued interest

Voluntary Withdrawal (VW) scheme: If you have cash savings outside CPF, you can repay CPF voluntarily before selling. This stops accrued interest from accumulating further. Only use this if you have liquid cash available; do not draw from other investments or create debt to repay CPF early.

Timing your sale: Interest accrues daily. Selling sooner rather than later reduces total accrued interest. If you have flexibility on timing, selling 1 to 2 years earlier could save SGD 10,000 to 30,000 in accrued interest, depending on the amount withdrawn.

Maximizing sale price: The only way to truly "beat" accrued interest is to sell your flat for a higher price. A 5% higher sale price (from good positioning and marketing) often offsets years of accrued interest accumulation.

Frequently asked questions

Can I defer CPF repayment until after the sale?

No. CPF repayment is due on the sale completion date. Your lawyer deducts it from the sale proceeds immediately. You cannot receive your net balance first and repay CPF later.

What if my sale proceeds are less than my CPF repayment?

This can happen on deeply negative equity (rare). If your CPF repayment is SGD 300,000 and your sale price is only SGD 250,000, you have a shortfall of SGD 50,000. You must repay this shortfall in cash to CPF Board. Plan your sale carefully to avoid this scenario.

Does accrued interest count towards my Ordinary Account minimum of SGD 20,000?

No. Your CPF minimum of SGD 20,000 is separate from accrued interest. After repaying the CPF withdrawal and accrued interest on sale, you must retain SGD 20,000 in your OA if you re enter the CPF housing scheme.

Can I negotiate the CPF repayment amount?

No. CPF repayment is set by statute. The interest rate and calculation methodology are fixed by CPF Board. There is no negotiation; the amount in the quotation is binding.

Winfred's Take

Most sellers are shocked by their CPF repayment amount on sale. A couple who bought a flat in 2003 for SGD 250,000 and withdrew SGD 200,000 from CPF might face a repayment of SGD 400,000 or more by 2023 due to accrued interest alone. The good news: this is completely normal and expected by CPF Board. Plan for it by requesting a quotation early. If the repayment is larger than expected, it means your property has been a good investment and your equity is sufficient to absorb it.
