To calculate if refinancing is worth it, divide your total refinancing costs (e.g., $3,000-$8,000 in Singapore) by your monthly savings from the lower rate. If the break-even period is shorter than your planned stay in the property, it's financially beneficial.
This cluster article focuses on the precise calculations Singapore homeowners need for refinancing decisions, building on our pillar guide to Singapore Mortgage Refinancing: The Complete Homejourney Guide. At Homejourney, we prioritize your financial safety by verifying rates from trusted banks like DBS, OCBC, UOB, HSBC, and Hong Leong Finance, ensuring transparent comparisons in a secure environment.
What is Mortgage Refinancing in Singapore?
Refinancing means taking a new loan to pay off your existing home loan, typically to secure a lower interest rate or better terms. Unlike repricing (staying with the same bank for a new rate), refinancing lets you switch banks like from DBS to Hong Leong Finance for competitive Hong Leong Finance refinancing rates.
In Singapore, most home loans peg to SORA (Singapore Overnight Rate Average), currently around 3.0-3.5% for 3-month SORA plus bank margin as of 2026. Refinancing makes sense if rates drop or your profile improves (e.g., higher income reducing TDSR). Homejourney's platform lets you compare Hong Leong Finance mortgage refinance options safely.
Key Factors Before Calculating: Singapore-Specific Rules
Under MAS regulations, Total Debt Servicing Ratio (TDSR) caps debt at 55% of income, and Loan-to-Value (LTV) limits apply (e.g., 75% for first HDB resale). Lock-in periods (2-5 years) trigger clawback fees if broken early—factor these in.
Hidden costs include valuation ($500-$1,500), legal fees ($2,000-$3,000), admin fees ($200-$500), and possible clawback (3 months' interest). Total costs: 0.5-1% of loan amount. Always check if you're past lock-in via Homejourney's bank rates page.
Step-by-Step: How to Calculate If Refinancing is Worth It
Follow this proven break-even formula, adapted for Singapore from standard methodologies[1][2][5].
- Gather Current Loan Details: Loan balance (e.g., $800,000), rate (e.g., 3.8%), remaining tenure (25 years), monthly payment ($4,200).
- Find New Loan Quote: Use Homejourney to compare rates—e.g., switch to Hong Leong Finance at 3.2% SORA + 0.5% margin. New payment: $3,950 (use our mortgage calculator).
- Calculate Monthly Savings: $4,200 - $3,950 = $250.
- Estimate Total Costs: $5,000 (legal + valuation + fees).
- Compute Break-Even Months: Costs ÷ Savings = $5,000 ÷ $250 = 20 months (1.7 years).
- Compare to Timeline: If staying 5+ years, refinance. Lifetime savings: $250 x 300 months = $75,000 minus costs.
This method ensures accuracy—input your numbers on Homejourney for instant results[3][6].
Real Singapore Example: HDB Refinance Calculation
Consider a $600,000 HDB loan in Tampines at 3.7% (payment: $3,150, 23 years left). Switching to Hong Leong Finance refinance at 3.1% drops payment to $2,900 ($250 savings). Costs: $4,200. Break-even: 17 months.
If selling in 2 years, skip it. But for 10 years, save $27,000 net. Track SORA trends on Homejourney to time it—rates fell 0.5% in early 2026 per MAS data.
The chart below shows recent interest rate trends in Singapore:
As seen, SORA stabilized post-2025 peak, favoring refinancers now.
Hidden Costs That Kill Savings: Singapore Breakdown
- Clawback Penalty: 1.5-3 months' interest if breaking lock-in (e.g., $3,000 on $800k loan).
- Valuation & Legal: Mandatory for bank switches; HDB flats need HDB approval.
- Processing Fees: $200-$1,000 per bank.
- CPF Changes: Accrued interest refunded but recalculated.
Total: Often $3,000-$10,000. Use our refinancing calculator at https://www.homejourney.sg/bank-rates#calculator to simulate. See Hidden Costs of Hong Leong Finance Refinance 2026 for details.
When to Refinance: Timing Tips for Singaporeans
- Post-lock-in expiry (check via Singpass on Homejourney).
- SORA drops >0.5% (monitor live on our platform).
- Income rise improves TDSR.
- Equity >20% LTV.
Avoid if selling soon or rates rising. For HDB vs bank, banks beat HDB's 2.6% p.a. flat rate—see our HDB Loan vs Bank Loan 2026 Guide.
