Key Takeaways

  • TDSR limits a borrower's total monthly debt payments to 55% of their gross monthly income.
  • Covers all outstanding debt obligations, including housing loans, car loans, and credit card balances.
  • Applies to all home loans issued by financial institutions in Singapore.
  • Variable income is subject to a 30% hair-cut deduction for debt service calculations.

Detailed Explanation

The Total Debt Servicing Ratio (TDSR) is a regulatory framework introduced by the Monetary Authority of Singapore (MAS) to prevent over-leveraging among property buyers. It restricts the maximum percentage of a borrower's gross monthly income that can be spent on total monthly debt repayments (including home loans, car loans, credit cards, and personal loans) to 55%.

TDSR applies to all housing loans granted by financial institutions in Singapore. For variable income (like commissions or rental), only 70% of the gross amount is counted towards the income assessment. Furthermore, for joint applications, a income-weighted average age is used to determine the maximum loan tenure.

Real-World Example If a borrower has a gross monthly salary of S$10,000, their maximum monthly debt obligations cannot exceed S$5,500 under the 55% TDSR cap. If they already pay S$1,500/month for a car loan and credit cards, the maximum home loan installment they can qualify for is S$4,000/month.
