Singapore mortgage calculator — how to use
Enter your property price, down payment amount, interest rate, and loan tenure to calculate your monthly mortgage repayment in Singapore. The calculator works for both HDB flat purchases and private property or condo purchases. It also generates a full year-by-year amortisation schedule showing exactly how much principal and interest you pay each year.
What is the minimum down payment for a home loan in Singapore?
For an HDB bank loan, the minimum down payment is 25% of the purchase price (LTV limit of 75%). For a private property bank loan, the minimum down payment is also 25% for your first property. If you are taking an HDB concessionary loan, the minimum down payment is 20% (LTV limit of 80%). At least 5% of the down payment must be in cash — the remainder can come from your CPF Ordinary Account.
HDB loan vs bank loan — which should you choose?
The HDB concessionary loan rate is 2.6% per annum, fixed at 0.1% above the CPF Ordinary Account interest rate. Bank loan rates are currently 3.0%–3.8% per annum but can be fixed for 2–3 years. The HDB loan offers more stability and flexibility while bank loans may offer lower initial rates but carry refinancing risk when the fixed period ends.
How is mortgage calculated in Singapore?
Singapore mortgage repayments are calculated using the standard reducing balance method. Each monthly payment covers the interest on the outstanding loan balance plus a portion of the principal. In early years, a larger portion goes toward interest. Over time, as the principal reduces, more of each payment goes toward principal. This is shown clearly in the amortisation schedule above.
