Home Loan / Mortgage Calculator Singapore
Estimate your monthly mortgage repayment, total interest and down payment for a Singapore home loan. Enter the price, down payment, interest rate and tenure — everything is computed instantly in your browser and nothing is sent anywhere.
Figures are indicative estimates based on a fixed interest rate over the full tenure. Actual bank packages often use floating or step-up rates, so your real repayment may differ. This tool does not check your eligibility or income — verify with your bank or a licensed mortgage adviser before committing.
What the calculator does
The calculator first works out your loan amount as the property price minus your down payment. It then applies the standard amortisation formula over your chosen tenure and interest rate to produce a fixed monthly instalment. From that instalment it derives the total you would repay over the life of the loan and how much of that is interest.
Key financing limits (informational, not advice)
- Loan-to-Value (LTV): For a first housing loan from a bank on a private property, the LTV is generally capped at 75% of the price or valuation (whichever is lower). You therefore fund at least 25% yourself.
- Cash portion: Of that 25% minimum down payment, at least 5% must be paid in cash; the remaining 20% can come from cash and/or your CPF Ordinary Account.
- Loan tenure: The maximum tenure for full 75% LTV is 30 years for private property (25 years for an HDB flat). A longer tenure — up to 35 years — or one that runs past age 65 tightens the LTV cap to 55%.
- TDSR: Your total monthly debt repayments, including this loan, must not exceed 55% of your gross monthly income under the Total Debt Servicing Ratio rule. This can limit your loan below the LTV cap.
- One-off costs: Beyond the down payment, budget for Buyer's Stamp Duty (BSD), any Additional Buyer's Stamp Duty (ABSD) and legal fees around completion.

|---|---|---|
| Maximum LTV — 1st housing loan | 75% | Of price or valuation, whichever is lower. |

| Minimum cash down payment | 5% | Must be paid in cash. |
| Maximum tenure — private (full LTV) | 30 years | Beyond 30 (up to 35) years the LTV cap drops to 55%. |
| Maximum tenure — HDB flat | 25 years | Bank loan on an HDB flat. |
| Total Debt Servicing Ratio (TDSR) | 55% | Of gross monthly income, across all debts. |

How is a monthly mortgage payment calculated?
A monthly mortgage payment is worked out using the standard amortisation formula. It depends on three inputs: the loan amount, the monthly interest rate (the annual rate divided by 12), and the loan tenure in months (the years multiplied by 12). Each equal monthly instalment covers the interest accrued that month plus a slice of the principal, so the loan is fully repaid by the end of the tenure. Early instalments are mostly interest and later ones are mostly principal. This calculator applies that formula to the loan amount that remains after your down payment.
What is the maximum home loan I can get in Singapore?
For your first residential property loan from a bank, the maximum Loan-to-Value (LTV) limit is generally 75% of the property price or valuation, whichever is lower. That means you can borrow up to 75% and must fund at least 25% as a down payment. The 75% cap assumes a loan tenure of up to 30 years for private property (25 years for an HDB flat) that does not run past age 65; a longer tenure or an older borrower lowers the LTV cap to 55%. Second and subsequent housing loans are also capped at lower LTV limits.
What is TDSR?
TDSR stands for Total Debt Servicing Ratio. It is a Monetary Authority of Singapore (MAS) rule that limits your total monthly debt repayments — including the new home loan, car loans, credit cards and other commitments — to at most 55% of your gross monthly income. Banks apply TDSR when sizing the loan they can offer you, so even if you meet the LTV limit, your actual approved loan may be smaller if your income cannot support the repayments within the 55% cap.
How much down payment do I need?
For a first private property loan at 75% LTV, the minimum down payment is 25% of the price. Of that, at least 5% must be paid in cash, and the remaining 20% can come from cash and/or your CPF Ordinary Account. On top of the down payment you should also budget for Buyer's Stamp Duty (BSD), any Additional Buyer's Stamp Duty (ABSD) and legal fees. These are all one-off costs due around completion, separate from the monthly repayment.
