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 27 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; Cost assumptions (rate, fees, commission), 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 and ECs?
For an HDB flat, or an executive condominium still within its minimum occupation period, 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.
