The HDB concessionary loan rate is pegged at the CPF OA rate plus 0.1%, which equals 2.6% per annum as of 2026.
The maximum loan tenure is 25 years for HDB loans and 30 years for bank loans (subject to MAS regulations and your age).
At the 75% Loan-to-Value limit, the minimum down payment is 25% for both an HDB loan and a bank loan. A bank loan needs at least 5% in cash. If a bank loan runs past age 65, or its tenure exceeds 25 years on an HDB flat or 30 years on other property, MAS caps LTV at 55% with at least 10% in cash.

This calculator uses the standard amortization formula to compute monthly mortgage payments based on loan amount, interest rate, and loan tenure. It also calculates the total interest paid over the full loan period. In Singapore, home loans come from banks (floating or fixed rate) or HDB (for HDB flats only, at concessionary rate).
The HDB Concessionary Loan rate is currently 2.6% per annum. Bank loans offer floating rates typically starting lower but subject to market changes. HDB loans allow up to 75% Loan-to-Value with no lock-in period and allow penalty-free early repayment. Bank loans may offer lower initial rates but often have lock-in periods of around 1 to 3 years with penalties for early repayment or refinancing. MAS caps a first bank housing loan at 75% LTV with at least 5% in cash, or 55% with at least 10% in cash if the tenure exceeds 25 years on an HDB flat or 30 years on other property, or the loan runs past age 65.
A $400,000 HDB loan at 2.6% for 25 years: monthly payment approximately $1,815. Total paid over 25 years: about $544,403. Total interest: about $144,403. A bank loan at 1.8% for the same amount and tenure: monthly payment approximately $1,657, total interest about $97,022 - a saving of about $47,381 if rates stay constant. TDSR limits all debt obligations to 55% of gross monthly income.
