Quick Answer
How much house can I afford in Singapore?
In Singapore, HDB flat buyers can borrow up to 90% LTV with MSR limited to 30% of monthly income. Private property buyers face TDSR at 55% and LTV of 75%. CPF OA can fund the down payment and monthly installments. BSD and ABSD (up to 60% for foreign buyers) significantly affect affordability. Our mortgage calculator factors in CPF OA usage, LTV limits, and stamp duties specific to your citizenship and property type.

How Mortgage Calculation Works
The mortgage calculator uses the standard amortization formula to compute your monthly payment. The loan amount (property price minus down payment) is divided into equal monthly payments over the loan term. Each payment consists of both principal and interest, with the proportion shifting over time — early payments are primarily interest, while later payments are primarily principal. The calculator generates a full amortization schedule showing the balance, principal paid, and interest paid for each month of the loan term.
Mortgage Payment Formula
M = P × [r(1+r)^n] / [(1+r)^n - 1], where M = monthly payment, P = loan principal (property price minus down payment), r = monthly interest rate (annual rate divided by 12), and n = total number of monthly payments (loan term in years × 12). Total interest paid = (M × n) - P. The amortization schedule shows that total interest often approaches or exceeds the principal for longer loan terms, making extra principal payments a valuable strategy for reducing total borrowing costs.
Worked Example: Mortgage Payment
A home priced at S$400,000 with a 20% down payment (S$80,000) results in a loan principal of S$320,000. At a 6.5% annual interest rate over a 30-year term: monthly rate r = 0.005417, n = 360 payments. Monthly payment M = S$320,000 × [0.005417(1.005417)^360] / [(1.005417)^360 - 1] = S$2,023. Total interest paid over 30 years = approximately S$408,280 — exceeding the original loan principal. With a 15-year term at the same rate, the monthly payment rises to S$2,788 but total interest drops to S$181,840, saving S$226,440 in interest.
Country-Specific Mortgage Considerations for Singapore
Singapore has unique property buying rules including different down payment requirements, mortgage interest deductibility, property tax structures, and closing costs. Our calculator accounts for GST at 9% where applicable, local property tax rates, and region-specific insurance requirements. Some countries require mortgage insurance for down payments below 20%, while others have government first-home buyer grants or stamp duty exemptions that affect total upfront costs.
Mortgage Methodology and Data Sources
Interest rate data is sourced from central bank publications and major lender rate sheets. Property tax rates come from local government tax authorities. Insurance estimates are based on national averages from insurance industry data. All rates and rules are verified at least quarterly and updated when central banks announce rate changes or when governments modify housing policy. Our amortization calculations follow standard financial mathematics as used by lending institutions worldwide.
