1. What CPF can be used for housing?
Only the CPF Ordinary Account (OA) can be used for housing. Special Account, Medisave, and Retirement Account funds cannot. OA can be applied to:
- Downpayment for an HDB or private property (subject to LTV / CPF use rules)
- Monthly mortgage instalment (in lieu of cash)
- Buyer's Stamp Duty (BSD)
- Legal fees for conveyancing
- HDB Home Protection Scheme (HPS) insurance premium
- Pledging as security to support an HDB or bank housing loan
CPF OA earns interest at 2.5% per annum (floor rate, reviewed quarterly). When used for housing, the OA balance decreases — but the "notional" interest you would have earned still accumulates as accrued interest, which you must refund on sale.
2. Valuation Limit and Withdrawal Limit
CPF Board imposes two ceilings on how much OA can be used over the life of the housing loan:
- Valuation Limit (VL) — the lower of the purchase price or the property valuation at the time of purchase. CPF use up to VL is freely allowed.
- Withdrawal Limit (WL) — currently 120% of VL. To continue using CPF between VL and WL, you must have set aside the Basic Retirement Sum (BRS) in your CPF.
See the dedicated Withdrawal Limit guide for the mechanics and BRS requirement.
3. Accrued interest — the "forgotten cost"
Every dollar of CPF OA used for housing is treated as a withdrawal from your retirement savings. On sale of the property, you must refund:
- The principal CPF used, plus
- The accrued interest at 2.5% per annum, compounded
For a borrower who used $200,000 of CPF over 10 years, the accrued interest is roughly $56,000 — and the total CPF refund on sale is $256,000. If sale proceeds are insufficient (after paying off outstanding loan), the shortfall is waived for new home purchases but the AI is real otherwise.

4. The age 95 rule (Budget 2024)
From 10 August 2024, CPF usage for housing loans is restricted to ensure that retirement adequacy is preserved:
- Borrower's age + loan tenure ≤ 95 years (for HDB loans).
- The loan tenure should ideally end by the youngest buyer's age 65 to qualify for the full CPF use and LTV.
- Older buyers face reduced LTV (e.g. 55% instead of 75%) and reduced Withdrawal Limits.
See the dedicated Age 95 Rule guide.
5. CPF refund on sale
On sale of the property, the CPF refund (principal + accrued interest) is computed and paid back into the seller's CPF OA before any cash proceeds are released. The order of priority is:
- Outstanding mortgage to bank / HDB
- CPF refund (principal + accrued interest) to seller's OA
- Cash to seller (the residual)
If the sale price is low (property has depreciated) or the loan is still large, the cash to the seller may be very small or zero. See the CPF Refund on Sale guide for worked scenarios.
