CPF vs Cash for Mortgage: Which is Smarter? | Homejourney
For most Singapore homebuyers, using cash over CPF for mortgage payments is smarter if you prioritize retirement savings and sale flexibility, as CPF earns guaranteed 2.5-4% interest while avoiding CPF accrued interest refunds upon property sale[1][2]. This cluster article dives into the tactical comparison, building on our pillar guide to Singapore home financing.
At Homejourney, we prioritize your safety and trust by verifying data from official sources like CPF Board and HDB, helping you make confident decisions without the risks of negative cash proceeds from CPF refund sale.
Why CPF vs Cash for Mortgage Matters in Singapore
Singapore's property market ties CPF tightly to homeownership, but using CPF Ordinary Account (OA) funds for mortgages means repaying with accrued interest upon sale, potentially leaving you with little cash[1][2]. Cash payments preserve CPF for retirement growth at risk-free rates up to 4% in Special Account (SA), hedging inflation[1][4].
This decision impacts Total Debt Servicing Ratio (TDSR) at 55% and Mortgage Servicing Ratio (MSR) at 30% for HDB flats[3]. Homejourney's bank rates page lets you compare DBS, OCBC, UOB rates instantly to see affordability.
Key Differences: CPF vs Cash Mortgage Payments
Using CPF feels convenient—no cash outflow—but it depletes your OA, which earns 2.5% (3.5% on first S$20,000). Transfer OA to SA for 4%+ to maximize growth[2]. Cash keeps liquidity for emergencies or investments.
| Using CPF | Using Cash | |
|---|---|---|
| Retirement Impact | Reduces future CPF Life payouts | Grows CPF for higher payouts[2] |
| Sale Proceeds | CPF refund sale with accrued interest may cause negative cash[1][2] | Full cash proceeds, no refund[1] |
| Interest Earned | Misses 2.5-4% CPF returns | CPF compounds risk-free[1][4] |
| Flexibility | Less cash for opportunities | Backup fund if job loss[2] |
Bank loans cap CPF use after Basic Retirement Sum (BRS): up to 20% of purchase price post-BRS[1][5]. HDB loans allow full CPF for resale flats[1].
Understanding CPF Accrued Interest Calculation
When you use CPF for downpayment or repayments, you must refund the principal plus accrued interest (at 2.5% compounded) upon sell property CPF return[1]. Example: S$100,000 CPF used at purchase, sold after 10 years at 2.5% = ~S$128,000 refund[1].
This erodes profits. In 2021, 9% of sales faced negative cash[2]. Read our deep dive: CPF Accrued Interest Explained: Impact on Property Sale | Homejourney .
Real Example: HDB Flat in Punggol vs Condo in Toa Payoh
Scenario 1: S$500,000 Punggol BTO HDB flat, HDB loan 2.6%, 25 years. Downpayment S$50,000 (10%). Monthly: S$1,800.
- Cash payments: CPF grows to S$300,000+ in 10 years at 3% avg.
- CPF payments: Refund S$250,000+ accrued on sale, netting S$50,000 cash vs S$200,000[1].
Scenario 2: S$1.2M Toa Payoh condo, bank loan 3.5% SORA-based, 25% down (S$240,000: 5% cash, 20% CPF/cash). Using cash monthly saves on accrued interest property bite[1]. Use Homejourney's mortgage calculator for your numbers.
