TDSR calculator Singapore
The Total Debt Servicing Ratio (TDSR) caps a borrower's monthly debt repayments, including the new property loan, at 55% of gross monthly income. Variable and rental income count after a haircut of at least 30%. A residential loan from a bank is tested at the higher of 4% and its own rate, not at the rate first paid.
Rules last changed on 30 September 2022.

Current rates
| Rule | Setting |
|---|---|
| Limit on total monthly debt repayments | 55% of gross monthly income |
| Variable and rental income | Counted after a haircut of at least 30% |
The loan fits when the ratio does not exceed the limit.
| Loan | Rate the ratio is tested at |
|---|---|
| Bank loan, residential property | The higher of 4% and the loan's own rate |
| Bank loan, non-residential property | The higher of 5% and the loan's own rate |
| HDB loan | The higher of 3% and the HDB loan rate |
The loan's own rate is its thereafter rate: the highest it can charge after any introductory or promotional rate.
The limit, worked
MAS's rule, applied: a borrower earning S$10,000 a month, with S$5,500 of monthly repayments before the new loan, is at 55%. That does not exceed the limit, so the borrowing fits; any new loan would have to fit in what is left.

Questions
How is TDSR calculated?
Add up every monthly debt repayment, including the new property loan's instalment, and divide by gross monthly income. The result may not exceed 55%.
What income counts?
Fixed income counts in full. Bonuses, commissions and other variable income, and rental income, count after a haircut of at least 30%; a lender may apply more.
Which interest rate is the loan tested at?
The higher of a floor and the loan's own rate after any introductory rate: 4% for a residential loan from a bank, 5% for non-residential, from 30 September 2022.
