TDSR Explained How It Affects Your Mortgage Eligibility: Benefits of Applying via Homejourney

This Monetary Authority of Singapore (MAS) rule ensures borrowers avoid over-leveraging, protecting you in a safe property market. Homejourney simplifies TDSR calculations with its instant eligibility calculator, helping you assess borrowing power securely via Singpass.
This cluster article dives into TDSR Singapore mechanics, calculations, and impacts on home loans, linking back to our pillar guide on TDSR Explained: Mortgage Eligibility & Bank Rates Guide. Discover actionable steps to maximize eligibility using Homejourney's verified tools for transparent, stress-free financing.
What is TDSR and Why Does It Matter in Singapore?
TDSR (Total Debt Servicing Ratio) measures all your monthly debt obligations—including home loans, car loans, credit card minimums, and personal loans—against your gross income. Singapore's TDSR limit is 55%, stricter for private properties than HDB's 30% Mortgage Servicing Ratio (MSR). This framework, enforced by MAS since 2013, prevents financial overextension amid rising interest rates.
For example, with a S$10,000 monthly income, your total debts cannot exceed S$5,500. Exceeding this blocks mortgage approval, even with strong credit. Homejourney's platform verifies your TDSR instantly, prioritizing user safety by auto-filling data via Singpass for accurate assessments.
TDSR Calculation: Step-by-Step Guide
Understanding TDSR calculation is key to mortgage eligibility TDSR. Banks use a standardized formula assuming a 30-year loan at the higher of 3.5% interest or 0.5% above current rates, plus existing debts.
- Calculate monthly mortgage payment: Use loan amount, tenure, and stress rate.
- Add other debts: Car loans (e.g., S$800/month), credit cards (5% of limit), student loans.
- Divide by gross income: (Total debts / Income) ≤ 55%.
Real Example: Mr. Tan earns S$8,000/month, has S$500 car loan and S$300 credit card payments. For a S$1.2M condo, stress-tested mortgage is S$3,800/month. Total debt: S$4,600 (57.5%)—exceeds 55%, ineligible. Reduce debts to qualify for S$1.1M.
| Monthly Income | Max Total Debt (55% TDSR) | Est. Mortgage (After S$1,000 Other Debts) |
|---|---|---|
| S$6,000 | S$3,300 | S$2,300 |
| S$10,000 | S$5,500 | S$4,500 |
| S$15,000 | S$8,250 | S$7,250 |

How TDSR Affects Your Mortgage Eligibility
TDSR Singapore limits borrowing more than income alone. Self-employed? Banks average 2-year income and apply conservative stress tests. Variable income (e.g., commissions) gets haircut. Age 55+? Max tenure drops to 25 years, shrinking loan size.
HDB buyers face MSR (30%) alongside TDSR—double check needed. Investors: Rental income counts at 70% after deductions, but TDSR aggregates all properties. Poor credit? Even under 55%, approvals falter. Homejourney's tools factor these precisely, connecting you to partners like DBS, OCBC, UOB.
Current trend: With SORA rates fluctuating, stress tests amplify payments. The chart below shows recent interest rate trends in Singapore:
As seen, 3M SORA hovered around 3.0-3.2% in late 2025, pushing stress-tested payments higher and tightening eligibility.
