The Total Debt Servicing Ratio (TDSR) limits your total monthly debt payments to 55% of your gross monthly income, directly determining your mortgage eligibility TDSR in Singapore.[5] This rule, enforced by the Monetary Authority of Singapore (MAS) since 2013, ensures responsible borrowing amid high property prices.[1][2]

What is TDSR and Why Does the 55% Limit Matter?
TDSR Singapore measures all your monthly debt obligations—including mortgages, car loans, credit cards—against your gross income.[4] The TDSR limit 55% caps these at 55% to prevent over-leveraging, tightened from 60% in December 2021 to stabilize the market.[2][5]
For example, with a $10,000 monthly income, your total debts cannot exceed $5,500. This affects mortgage eligibility TDSR by reducing loan quantum if you have existing debts. Homejourney's calculator at https://www.homejourney.sg/bank-rates#calculator instantly shows your limit, factoring in real-time data for DBS, OCBC, UOB, and more.
Unlike MSR (30% for HDB/EC mortgages only), TDSR applies to all loans property-wide.[2] Recent updates as of 2026 confirm the 55% threshold remains, with banks like HSBC and Standard Chartered applying it strictly.[1]
How is TDSR Calculated? Step-by-Step Breakdown
TDSR calculation uses: TDSR = (Total Monthly Debt Payments / Gross Monthly Income) x 100.[4] Debts include full mortgage/loan instalments, minimum credit card payments, and 20% of guarantor obligations.[1]
Income: Fixed pay (100%), variable (bonuses, rentals) haircut 30% over 12 months.[2] Assets like stocks can add income: $100,000 eligible assets yield ~$625/month over 48 months after 70% haircut.[1]
Actionable Steps for TDSR Calculation:
- Sum all debts: e.g., $2,000 mortgage + $500 car + $200 cards = $2,700.
- Assess income: $8,000 fixed + $2,000 bonus (70% = $1,400) = $9,400.
- Compute: $2,700 / $9,400 = 28.7% (under 55%).
- Test new mortgage: Add projected payment; stay below 55%.
Joint applicants use aggregated totals and income-weighted average age for tenure (max 35 years private, 30 HDB minus age).[1][3] Try Homejourney's tool at https://www.homejourney.sg/bank-rates for precise TDSR calculation.
TDSR Examples: Real Singapore Scenarios
Scenario 1: Single buyer, $6,000 income, no debts. At 3% interest, 25-year tenure, TDSR allows ~$330,000 loan (monthly ~$1,800, 30% of income).[3]
| Income | Max Debt (55% TDSR) | Est. Mortgage (~3% rate, 25yrs) |
|---|---|---|
| $10,000 | $5,500 | $800,000-$900,000 |
| $15,000 (joint) | $8,250 | $1.2M-$1.4M |
| $6,000 + $1,000 car loan | $2,530 left | $350,000-$400,000 |
With $1,000 car loan, borrowing drops sharply—pay off debts first. For HDB upgraders in areas like Punggol, factor MSR too. Homejourney verifies your scenario safely via Singpass integration.
How to Improve Your Mortgage Eligibility Under TDSR
Boost capacity: 1) Pay down debts (e.g., clear cards for instant 5-10% gain).[2] 2) Increase fixed income or stabilize variable proofs. 3) Use assets for extra income stream.[1]
- Reduce Debts: Target high-interest first; refinance car loans if over-TDSR.
