DBS Home Loan Refinancing Calculator
Comprehensive Guide to DBS Home Loan Refinancing
Module A: Introduction & Importance
Refinancing your home loan with DBS Bank can potentially save you thousands of dollars over the life of your mortgage. As Singapore’s largest bank with over S$600 billion in assets, DBS offers some of the most competitive home loan packages in the market. This calculator helps you determine whether refinancing your existing home loan with DBS would be financially beneficial by comparing your current loan terms with potential new terms from DBS.
The importance of refinancing cannot be overstated in today’s volatile interest rate environment. According to the Monetary Authority of Singapore (MAS), home loan interest rates have fluctuated between 1.5% to 4.5% over the past decade. Even a 0.5% reduction in your interest rate can translate to significant savings over a 25-year loan term.

Module C: Formula & Methodology
Our calculator uses precise financial mathematics to determine your refinancing benefits. Here’s the methodology:
1. Monthly Payment Calculation
We use the standard mortgage payment formula:
M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]
Where:
M = Monthly payment
P = Principal loan amount
i = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years × 12)
2. Interest Savings Calculation
Total interest for each loan is calculated by:
Total Interest = (Monthly Payment × Total Payments) – Principal
3. Break-even Analysis
We determine how many months it will take for your monthly savings to cover the refinancing costs:
Break-even (months) = (Refinancing Costs) / (Monthly Savings)
4. Chart Visualization
The interactive chart shows:
- Cumulative interest paid under current loan (blue line)
- Cumulative interest paid with DBS refinancing (green line)
- Break-even point (red vertical line)
- Total savings area (shaded region)

Module F: Expert Tips for Maximum Savings
When to Refinance:
- When interest rates drop by at least 0.75% from your current rate
- When you’re 5+ years into your current loan (to avoid early repayment penalties)
- When your credit score has improved significantly (720+ for best rates)
- When DBS offers special promotions with waived fees
What to Watch Out For:
- Lock-in Periods: DBS typically has 2-3 year lock-ins. Calculate if you’ll stay that long
- Valuation Fees: Budget S$200-S$500 for property valuation
- Legal Fees: Even with coverage, check for any hidden costs
- Floating vs Fixed: Floating rates are lower but riskier in rising rate environments
- CPF Usage: Consider how refinancing affects your CPF contributions
Negotiation Strategies:
- Get quotes from 2-3 banks to leverage against DBS
- Ask about loyalty discounts if you’re an existing DBS customer
- Time your refinancing near month-end when banks have quotas to fill
- Consider bundling with DBS insurance products for better rates
Module G: Interactive FAQ
How does DBS determine my refinancing eligibility?
DBS evaluates several factors for refinancing eligibility:
- Loan-to-Value (LTV) Ratio: Maximum 75% for HDB, 80% for private properties
- Total Debt Servicing Ratio (TDSR): Must be ≤60% of your gross monthly income
- Credit Score: Minimum 650, but 720+ gets better rates
- Property Valuation: Current market value must support the loan amount
- Employment Stability: Typically require 2+ years with current employer
You can check your eligibility using DBS’s online pre-approval tool before applying.
What documents do I need to refinance with DBS?
Prepare these documents for a smooth refinancing process:
- NRIC (for Singaporeans/PR) or Passport (for foreigners)
- Latest 3 months’ payslips or 2 years’ NOA for self-employed
- Latest 12 months’ CPF contribution history
- Current home loan statement from existing bank
- Property tax bill or latest service & conservancy charges statement
- Option to Purchase (if refinancing during property purchase)
- Latest credit card and other loan statements
DBS may request additional documents depending on your specific situation.
How long does the DBS refinancing process take?
The typical refinancing timeline with DBS is:
| Stage | Duration |
| Application Submission | 1 day |
| In-Principle Approval | 1-3 working days |
| Property Valuation | 3-5 working days |
| Legal Documentation | 5-7 working days |
| Completion & Disbursement | 7-10 working days |
The entire process typically takes 3-4 weeks from application to completion.
Can I refinance if I’m still in the lock-in period with my current bank?
Yes, but there are important considerations:
- Early Repayment Penalty: Typically 1.5% of the redeemed amount
- Cost-Benefit Analysis: Use our calculator to see if savings outweigh penalties
- DBS Clause: Some DBS packages cover early repayment penalties up to S$1,500
- Negotiation: Your current bank might waive penalties if you refinance with them
Example: If your penalty is S$3,000 but you’ll save S$300/month, you’ll break even in 10 months. If you plan to stay in the property longer, it may still be worthwhile.
How does refinancing affect my CPF usage?
Refinancing has several CPF implications:
If you used CPF for initial purchase:
- You must refund the principal amount withdrawn plus accrued interest
- The accrued interest is calculated at the CPF OA rate (currently 2.5%)
- This may reduce your available CPF funds for other uses
If you didn’t use CPF initially:
- You can choose to start using CPF for the refinanced loan
- This may reduce your monthly cash outlay
- But remember CPF used must be repaid with interest when you sell
Use the CPF Housing Withdrawal Calculator to estimate the impact.
