Banks calculate TDSR at the stress rate of 4%, not the loan's actual rate. Variable income (commissions, rental) is haircut by 30%.
What is TDSR?
The Total Debt Servicing Ratio is a Monetary Authority of Singapore rule limiting monthly debt obligations — across all credit facilities — to 55% of gross monthly income. Introduced in June 2013 to prevent borrowers from over-leveraging.
What counts as debt?
- The new home loan you are applying for (calculated at the 4% stress rate)
- Other property mortgages
- Car loans and renovation loans
- Credit-card minimum monthly payments
- Personal / student / unsecured credit lines
How income is assessed
- Fixed salary: taken at 100% of gross monthly income
- Variable income (bonuses, commissions, rental): haircut by 30% — only 70% counts
- Self-employed: usually based on the last 2 years of Notice of Assessment
