Which CPF Account Is Used for Housing
Singapore’s CPF system has three main accounts: the Ordinary Account (OA), the Special Account (SA), and the MediSave Account (MA). Only the Ordinary Account can be used for property purchases and mortgage repayments.
The CPF OA earns interest at a rate of:
- 2.5% per annum (guaranteed floor rate for OA balances)
- An additional 1% per annum on the first $20,000 of OA balances (part of the extra interest applicable to the first $60,000 of combined CPF balances)
The Special Account earns 4% per annum — meaningfully higher than the OA. This rate differential is central to the retirement trade-off when a buyer uses OA savings aggressively for housing.
What CPF OA Can Be Used For
CPF OA can be applied to:
- Initial downpayment: The portion of the purchase price not covered by the bank loan (i.e., at least 25% for the first bank loan — 5% must be in cash, 20% can be CPF or cash)
- Monthly mortgage repayments: For both HDB loans and bank loans, the monthly instalment can be paid entirely from CPF OA if there is sufficient balance
- Stamp duties: BSD and ABSD can be paid using CPF OA (for eligible properties)
- Legal fees: Conveyancing legal fees for HDB purchases can be paid from CPF OA; for private property, CPF can be used for legal fees up to certain limits
CPF OA cannot be used to pay cash-over-valuation (COV) in HDB resale transactions — COV must be paid in cash.
Withdrawal Limits
The CPF Board caps how much OA can be withdrawn for housing through two limits:
Valuation Limit (VL)
The Valuation Limit (VL) is the lower of:
- The purchase price of the property, or
- The HDB/bank valuation of the property at the time of purchase
CPF withdrawal up to the VL is available without restriction (subject to the remaining lease rule — see below).
Withdrawal Limit (WL)
The Withdrawal Limit (WL) is 120% of the Valuation Limit. Once total CPF withdrawal for a property reaches the WL, no further CPF can be withdrawn for that property — the remaining monthly instalments must be paid entirely in cash.
Example: A property with a valuation of $500,000.
- VL = $500,000
- WL = $600,000 (120% × $500,000)
Total CPF withdrawal across the life of ownership (downpayment + monthly repayments) cannot exceed $600,000 for this property. Once this limit is hit, the owner pays monthly instalments from cash even if there is CPF OA balance available.
Remaining Lease Proration
For properties where the remaining lease does not cover the youngest owner to age 95, the Withdrawal Limit is prorated. For very short-lease properties (remaining lease < 20 years at the youngest buyer’s age), CPF use may be completely disallowed. See the dedicated CPF Housing Withdrawal Limits article for the proration formula.
The Accrued Interest Obligation
This is the most commonly misunderstood aspect of CPF housing usage. Every dollar of CPF OA withdrawn for property is not a grant — it must be refunded to CPF upon the sale of the property, together with the interest it would have earned at the OA rate of 2.5% p.a. if it had remained in the CPF account.
This is called the accrued interest obligation. It accrues from the date each CPF withdrawal is made.
Worked Example
A buyer withdraws $200,000 from CPF OA for a property purchased in 2016 and sells the property in 2026 — 10 years later.
- Principal withdrawn: $200,000
- Accrued interest at 2.5% p.a. compounded over 10 years: approximately $55,800
- Total CPF refund required on sale: approximately $255,800
This amount is refunded automatically from the sale proceeds before the net cash proceeds are released to the seller. The refunded amount goes back into the seller’s CPF OA — it is not lost money, but it reduces the liquid cash the seller receives from the sale.
Agent note: Sellers who have used CPF heavily for mortgage repayments over many years are often surprised at how large the CPF refund amount is relative to the gross sale proceeds. Always walk the seller through the estimated CPF refund amount when establishing the minimum acceptable sale price — they need to understand the net cash proceeds, not just the headline sale price.
The Retirement Trade-Off
Using CPF OA for housing is not “free money.” Every dollar used for housing is a dollar not growing in CPF at 2.5% p.a. (or in the SA at 4% p.a., if the buyer would otherwise have transferred OA to SA). For buyers with long holding periods, the compounding effect is significant.
There is a school of thought among financial planners that buyers with sufficient cash flow should pay mortgage instalments in cash and preserve CPF OA balances for retirement — because CPF statutory interest rates (2.5–4%) often exceed the after-tax yield on cash deposits, and because the Full Retirement Sum (FRS) threshold is rising annually.
CEA agents should not advise clients on whether to use CPF or cash for mortgage repayments — this is a financial planning decision. The agent’s role is to:
- Confirm that CPF is available for the purchase (correct CPF account, within withdrawal limits, lease meets age-95 rule)
- Flag the accrued interest obligation to sellers who have used CPF heavily, so they understand the net sale proceeds before signing an OTP
- Refer clients to a financial planner or the CPF Board for advice on whether to optimise CPF usage
CPF OA for HDB vs Private Property
| Feature | HDB Flat | Private Property |
|---|---|---|
| CPF OA for downpayment | Yes (HDB loan: up to full downpayment; bank loan: above 5% cash) | Yes (above 5% cash component) |
| CPF OA for monthly repayments | Yes | Yes |
| Withdrawal Limit (WL) | 120% of VL | 120% of VL |
| Accrued interest on sale | Yes — refunded to CPF OA | Yes — refunded to CPF OA |
| COV payable in CPF | No — cash only | N/A (no COV concept for private) |
| Remaining lease rule | Yes — age-95 rule applies | Yes — age-95 rule applies |
Using LEVR for CPF-Inclusive Affordability Checks
LEVR’s Property Affordability Calculator models the maximum purchase price for any buyer — and the downpayment breakdown (CPF vs cash) is an input that determines the actual cash required at completion. Use this to confirm that the buyer has sufficient CPF OA balance and cash on hand before proceeding to the OTP stage.
Disclaimer (Block 3): LEVR's calculator outputs are estimates based on inputs provided and current regulatory parameters as known at time of publication. They are not a guarantee of borrowing capacity, stamp duty liability, or CPF eligibility. Regulatory thresholds and rates may change. Always verify with IRAS, your bank, or a licensed financial advisor before making financial decisions.
