What is TDSR and Why Does It Matter in Singapore?
The Monetary Authority of Singapore (MAS) introduced TDSR in 2013 to prevent overborrowing amid rising property prices[4]. Today, the TDSR limit 55% applies to all property loans from financial institutions, covering not just mortgages but all debts like car loans, credit cards, and student loans[3].
For example, with a $10,000 monthly gross income, your total debt repayments can't exceed $5,500. This safeguards borrowers and stabilizes the market, as seen in recent tightening from 60% to 55% in December 2021[2]. Homejourney's eligibility calculator on our mortgage calculator page instantly shows your borrowing power under these rules.
TDSR Calculation: Step-by-Step Formula
TDSR calculation uses this MAS formula: (Total monthly debt obligations / Gross monthly income) x 100% ≤ 55%[7]. Banks stress-test at a minimum 4% interest rate floor for realism, even if current rates are lower[3].
- Gross monthly income: Pre-tax salary, excluding CPF. Variable income (bonuses, commissions) gets a 30% haircut, averaged over 12 months[3].
- Total debt obligations: Mortgage + existing loans + minimum credit card payments.
- Loan tenure: Based on income-weighted age of borrowers, max 75 years or retirement age[1].

Real-World TDSR Examples for Singapore Buyers
Scenario 1: Single buyer, $8,000 income, no debts, 4% rate, 30-year tenure. Max mortgage payment: $4,400 (55%). This affords ~$900,000 loan for a Punggol BTO flat.
Scenario 2: Couple, $15,000 combined, $1,000 car loan. Max total debt: $8,250. After car loan, mortgage capped at $7,250/month—enough for $1.5M condo in Yishun.

|---|---|---|
| $10,000 | $5,500 | $4,500 |
| $15,000 | $8,250 | $7,250 |
| $20,000 | $11,000 | $10,000 |

TDSR vs MSR: Key Differences for HDB Buyers
TDSR is universal at 55%; MSR caps HDB/EC mortgages at 30% of income[3]. Both apply, so HDB upgraders face dual limits. For private properties, only TDSR matters.
Insider tip: Joint applications with family can boost income-weighted age, shortening tenure but passing TDSR via higher earners[1]. Homejourney verifies your eligibility transparently.
Current Bank Rates Impact on TDSR Eligibility
Lower rates mean lower payments, freeing TDSR headroom. SORA (Singapore Overnight Rate Average) benchmarks most loans—track it via Homejourney.
