Executive Summary: How to Use CPF for Your HDB Purchase Safely
For most Singaporean buyers, CPF Ordinary Account (CPF OA) savings are the single biggest tool to finance an HDB flat – from down payment to monthly instalments and even legal fees.[8] Used well, CPF helps you buy a home earlier without overstretching your cash. Used wrongly, it can compromise your retirement, blow your budget for an upgrade, or even limit your future home options due to CPF HDB rules on lease and withdrawal limits.[8]

Chapter 1: CPF Basics for HDB Buyers
1.1 What is CPF OA and why it matters for HDB
Your CPF Ordinary Account (OA) is where a portion of your monthly CPF contributions go. For most working adults, OA contributions range from 23% to 11% of wages (combined employer + employee), decreasing with age as more is channelled to SA and MA.[3] CPF OA earns at least 2.5% p.a., with extra interest on the first S$60,000 combined balance (up to 3.5% for many members).[8]
For HDB buyers, CPF OA is crucial because you can use it to:
- Pay HDB down payment with CPF
- Service your monthly HDB loan or bank loan instalments
- Pay stamp duty and legal fees
- Pay for the compulsory Home Protection Scheme (HPS) for HDB flats[8]
In heartland estates like Punggol, Sengkang or Jurong West, young couples often rely heavily on CPF OA because their cash savings are still building up. I’ve seen many couples in their late 20s manage a S$500,000–S$600,000 4-room resale flat with almost entirely CPF, keeping cash as emergency reserves instead of locking it into the property.
1.2 CPF Housing Scheme overview
CPF usage for property is governed by the CPF Housing Scheme. Under this scheme, your OA can be used to buy:
- New HDB BTO flats from HDB
- HDB resale flats
- New or resale private properties in Singapore (not the focus of this guide)[8]
Key high-level rules for HDB:
- The flat must have a remaining lease of at least 20 years to use CPF at all.[8]
- CPF usage may be capped when the lease does not cover the youngest buyer till age 95.[8]
- Total CPF plus loan is capped by HDB or bank loan-to-value rules and MAS income rules.
1.3 CPF vs cash: why CPF is not “free money”
Many first-time buyers treat CPF like free money because they never touch it physically. In reality, every dollar of CPF you use for housing has to be “returned” when you sell the flat – principal plus accrued interest you would have earned if the money stayed in CPF.[8]
This has three big implications:
- If your flat does not appreciate much, you may get very little cash proceeds after refunding CPF.
- Using too much CPF can shrink your retirement nest egg later.
- Upgraders may find they have less cash on hand after sale than they expected.
Homejourney’s role is to make these trade-offs transparent so you can decide, not wake up 15 years later wondering where your sale proceeds went.
Chapter 2: What You Can Use CPF OA for in an HDB Purchase
2.1 Allowed uses of CPF OA for HDB
According to CPF’s official guidance, your OA savings can be used for all major parts of an HDB purchase under the Housing Scheme.[8]
2.2 What you cannot use CPF for
You cannot use CPF OA to pay for:
- Renovation works (tiling, carpentry, hacking, lighting)
- Furniture and appliances (sofa, beds, fridge, aircon units, etc.)
- Monthly conservancy or service and conservancy charges (S&CC)
- Property tax – must be paid in cash
This is where many buyers in mature estates like Tampines or Ang Mo Kio get a shock. They budget CPF carefully for purchase but forget that renovation for an older 4-room resale can easily hit S$40,000–S$60,000. That is why Homejourney encourages you to always run a full budget, including renovation and post-move costs, together with your home loan planning.
2.3 CPF usage when buying with co-owners
When you buy with a spouse, parent or sibling, your combined CPF OA can be used, but usage must follow:
- Ownership shares (e.g. 50–50, 99–1)
- CPF housing limits based on the youngest owner’s age and remaining lease[8]
Example: Husband (30) and wife (28) buy a 4-room resale in Bukit Panjang with 88 years lease left. CPF usage limits are based on the 28-year-old’s age, not the older spouse. This affects how much CPF they can use before hitting valuation and withdrawal limits (explained in Chapter 4).
Chapter 3: CPF Down Payment for HDB – HDB Loan vs Bank Loan
3.1 HDB loan vs bank loan: down payment structure
The way you use CPF for HDB down payment depends mainly on whether you take an HDB concessionary loan or a bank loan.

3.2 Using CPF OA for down payment – practical examples
Example 1 – 4-room BTO in Tengah (S$380,000 assumed):
- Price: S$380,000
- HDB loan: 75% = S$285,000
- Down payment 25%: S$95,000
- You can use up to S$95,000 CPF OA if you have enough in OA. No minimum cash required for HDB loan.[6]
Example 2 – 4-room resale in Queenstown (S$800,000 assumed):
- Price: S$800,000
- Bank loan: 75% = S$600,000
- Down payment 25%: S$200,000
- Minimum 5% cash: S$40,000 (cannot be CPF)
- CPF OA usable for down payment: S$160,000
