1. Introduction to CPF vs Cash Dilemma

In Singapore's property market, the CPF property decision between OA and cash is pivotal. CPF OA offers 2.5% risk-free interest, but using it means forgoing growth for housing.[1][4] Cash provides liquidity for investments potentially yielding higher returns.[2]

Why does this matter? Poor choices lead to eroded retirement savings or missed investment gains. Homejourney's analysis, grounded in CPF Board data, shows balanced use preserves flexibility. For first-time buyers, this guide ensures you meet MSR/TDSR limits safely.

Current CPF OA rate (Q1 2026): 2.5% p.a., with extra 1% on first $60,000 combined balances.[6] Compare to bank loans via Homejourney's bank rates page.

2. CPF OA Fundamentals

What is CPF OA?

CPF Ordinary Account holds 23% of wages (up to $6,800/month for those under 55), used for housing, education, healthcare.[4] It earns at least 2.5% p.a., floored against bank rates.[1]

Interest Rates Breakdown

OA: 2.5% base. First $20,000 OA earns up to 3.5% via extra interest.[1][4] Transfer to Special Account (SA) for 4%+.[1] These risk-free rates beat fixed deposits (0.8-1.6% as of Dec 2025).[4]

The chart below shows recent interest rate trends in Singapore:

Rates remain stable, making CPF a defensive asset amid SORA fluctuations around 3%.[6]

3. Singapore Property Payment Rules

HDB Flats

HDB loans: 10-25% downpayment, fully CPF-eligible (no mandatory cash).[3] Bank loans: 25% down (5% cash + 20% CPF/cash).[1]

Private Properties (Condo/Resale)

Always 25% downpayment: First 5% cash only, next 20% CPF OA or cash.[1][7] Foreigners: 100% cash + ABSD, no CPF.[7]

Property Type	Min Downpayment	Cash Required	CPF OA Allowed

HDB (Bank Loan)	25%	5%	20%
Private Property	25%	5%	20%

4. The CPF Opportunity Cost Explained

Using CPF OA forfeits 2.5% growth. $20,000 left in OA grows to $39,700 in 20 years.[4] Accrued interest must be refunded upon sale, plus original amount.[2]

Cash alternative: Invest in stocks (historical S&P 500 ~7-10% p.a.), but risky.[2] Keep $20,000 OA buffer for emergencies.[4]

5. When to Use CPF OA vs Cash

No choice: Insufficient cash for 5-25% down.[2]
CPF better: Cash earns >2.5% elsewhere (e.g., stocks).[2]
Cash better: Preserve CPF for retirement; low-risk profile.[1]
Combo: Use minimal CPF, keep $20k buffer.[4]

Insider tip: For Tengah HDB (~$500k), use CPF for 20% ($100k) if cash tight, but save cash for ABSD if upgrading.CPF取款限额完整指南：Homejourney房产买家必读

6. Real Calculations & Examples

Example 1: $1M Condo Downpayment

25% = $250k (5% cash $50k + 20% CPF $200k). CPF OA at 2.5%: $200k grows to $200k + $101k interest in 10 years if unused.[2]

Cash invested at 7%: $288k total.[2] Upon sale, refund $301k to CPF.

Example 2: HDB $600k (Bank Loan)

25% = $150k (5% cash $30k + $120k CPF). MSR limits instalments to 30% income.

8. Risks & Considerations
