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 80% 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 2-3 years with penalties for early repayment or refinancing.
A $400,000 HDB loan at 2.6% for 25 years: monthly payment approximately $1,819. Total paid over 25 years: $545,700. Total interest: $145,700. A bank loan at 1.8% for the same amount and tenure: monthly payment approximately $1,671, total interest $101,300 - a saving of $44,400 if rates stay constant. TDSR limits all debt obligations to 55% of gross monthly income.
