TDSR and LTV calculator: how much can I borrow?
A home loan in Singapore is capped twice: by loan-to-value, a share of the price, and by debt servicing, a share of your income tested at a stress rate. The lower of the two is what you can borrow.
Rates in force on 23 Sept 2026
Work out how much you can borrow
Loan number 1, 75% LTV over 30 years. Capped by the total debt servicing ratio. Interest at the configured default rate, not a quote.
LTV limits in force from 20 Aug 2024; TDSR and MSR in force from 30 Sept 2022; Default interest rate assumption, set from 1 Jan 2020.
How much of the price can a bank lend?
A bank can lend up to 75%, 45% and 35% of the price or valuation on a borrower's first, second and third or later housing loan, falling to 55%, 25% and 15% if the tenure exceeds 30 years (25 for an HDB flat) or the loan runs past age 65; an HDB loan covers up to 75%.
What is the TDSR limit in Singapore?
Under the total debt servicing ratio, all monthly debt repayments including the new home loan may not exceed 55% of gross monthly income, and the loan is tested at a medium-term interest rate of at least 4% for a bank loan (3% for an HDB loan).
What is the MSR for HDB flats?
For an HDB flat, the mortgage servicing ratio caps the home loan instalment alone at 30% of gross monthly income, on top of the 55% TDSR.
Loan-to-value limits
| Loan | Maximum LTV | Long tenure or past age limit | Minimum cash |
|---|---|---|---|
| First housing loan | 75% | 55% | 5% |
| Second housing loan | 45% | 25% | 25% |
| Third or later housing loan | 35% | 15% | 25% |
Debt servicing limits
| Limit | Share of monthly income |
|---|---|
| Total debt servicing ratio (TDSR), all loans | 55% |
| Mortgage servicing ratio (MSR), HDB flats | 30% |
Stress-test rate: 4% for bank loans, 3% for HDB loans. Where you leave the interest rate blank, the calculator uses 3%, an assumption rather than a quote.
