1. CPF Basics for Monthly Mortgage Payments

CPF Ordinary Account (OA) savings earn 2.5% p.a. floor interest (Q1 2026) and can fund CPF monthly mortgage payments for HDB flats and private properties.[3][1] This includes downpayments, monthly installments, stamp duties, and legal fees, preserving your cash for emergencies.[3] Homejourney's mortgage calculator at https://www.homejourney.sg/bank-rates#calculator simulates your OA usage instantly.

Key rule: Property lease must cover the youngest buyer to age 95 for full CPF usage.[5] For resale HDB, minimum 20-year lease required. Refunds with accrued interest are mandatory upon sale to restore retirement savings.[3]

2026 CPF Interest Rates Table

Account	Q1 2026 Rate	Usage for Housing
Ordinary Account (OA)	2.5% p.a. (floor)	Downpayments, installments
Special Account (SA)	4% p.a. (floor)	Top-up OA if needed
MediSave (MA)	4% p.a. (floor)	Limited top-ups

Source: CPF Board Q1 2026.[1] Pro tip: Use OA first as it earns the lowest rate, topped up from SA for higher returns.

2. How CPF Loan Repayment Works

To use CPF for monthly mortgage payments, apply via CPF Portal with Singpass after HFE letter or OTP.[3] Banks like DBS, OCBC, UOB auto-deduct from OA monthly; HDB via their portal.[1] Monthly CPF OA accrual (from salary contributions) covers repayments, with refunds on over-usage.[2]

Process: 1) Get HFE from bank/HDB. 2) Submit CPF usage request. 3) Set up GIRO for cash shortfall. Homejourney's multi-bank application at https://www.homejourney.sg/bank-rates uses Singpass to pre-fill CPF data for faster approval.

Downpayment Requirements 2026 Table

Property/Loan Type	Downpayment %	Min Cash %	CPF Allowed
HDB Resale (HDB Loan)	25%	5%	20%
HDB BTO (HDB Loan)	10-25%	0%	100%
Private Property (Bank Loan)	25%	5%	20% up to valuation

Verify on HDB/CPF sites; filter budgets on Homejourney property search.[1][2]

3. Pros and Cons of CPF Servicing Mortgage

Pros of CPF monthly mortgage: Reduces cash outflow, OA earns 2.5% offsetting loan rates (~3% SORA), preserves liquidity for investments.[1][2] Tax-free interest, automatic deductions simplify budgeting.

Cons: Locks retirement funds (refund on sale with interest), opportunity cost if OA interest < loan rate, limited by OA balance.[3] Cannot use for non-housing after age 55 without penalties.

Pro: Up to 30% mortgage burden reduction via CPF OA monthly.[1]
Con: Sale refunds reduce net proceeds.[3]

4. HDB Loans vs Bank Loans with CPF

HDB loans (2.6% fixed, 0.1% above OA) allow full CPF for BTO downpayments; bank loans (SORA-based) cap CPF at 20% downpayment but unlimited monthly.[1][3] Banks offer flexibility but fluctuate with rates.

Example: $500k HDB resale – HDB loan: 25% down ($125k, 5% cash min), full CPF monthly ok. Bank loan: Same downpayment, but compare rates on Homejourney bank-rates from DBS, OCBC, UOB, HSBC.

5. CPF OA Monthly Limits and Regulations

No hard cap on monthly CPF loan repayment beyond OA balance + accrual; must leave interest buffer (~3 months).[2] TDSR (55% income) includes CPF payments.[6] For private properties, CPF up to lower of price/valuation.[5]

Insider tip: Refund overpayments monthly to compound interest. Use Homejourney's tools for precise limits.

6. TDSR, MSR, and CPF Usage

Total Debt Servicing Ratio (TDSR) limits debts to 55% gross income; Mortgage Servicing Ratio (MSR) 30% for HDB.[1] CPF counts fully, but OA buffer proves affordability.[2]

Example: $10k income – MSR $3k max. CPF covers without cash stress. Test on Homejourney calculator.

7. Interest Rates and SORA Impact

SORA (Singapore Overnight Rate Average) benchmarks bank loans at ~3% (2026).[1] CPF OA at 2.5% provides effective offset. Fixed HDB at 2.6% stable.

The chart below shows recent interest rate trends in Singapore:

Rates stable ~3% favor CPF usage for long tenures.[1] Track live SORA on Homejourney.

8. Key 2026 CPF Changes Affecting Mortgages

Higher contributions boost OA for more CPF monthly mortgage capacity.[4] MMSS matches MA top-ups up to $1k.[7] Younger workers gain compounding for housing.[4]

Downside: Lower take-home pay; plan via Homejourney eligibility tools.

9. Real Singapore Examples and Calculations

Example 1: Punggol BTO HDB ($500k, 25-year HDB loan @2.6%) Monthly: $2,300. CPF OA covers fully if balance sufficient. Cash saved: $55k/year.

Calc: OA needed ~$500k principal use + interest refund. Vs cash: CPF saves liquidity, earns 2.5%.[1]

Example 2: Tampines Private Condo ($1.2m, 30-year bank loan SORA+0.5%) Monthly $5k. CPF covers 80%, cash 20%. TDSR compliant at $15k income.
