How is the monthly mortgage calculated?
The monthly repayment uses the standard amortization formula: M = P × r(1+r)ⁿ / ((1+r)ⁿ − 1), where P is the loan amount, r is the monthly interest rate, and n is the total number of monthly payments. Each month a portion of your payment goes towards interest and the rest reduces the principal.
Singapore loan-to-value (LTV) limits
- First housing loan: up to 75% LTV — 5% cash + 20% cash/CPF down payment.
- Second housing loan: up to 45% LTV — 25% cash + 30% cash/CPF down payment.
- Third loan or more: up to 35% LTV.
- Tenure beyond 65 years of age or 30 years (private) / 25 years (HDB) reduces the LTV cap.
Don't forget TDSR
Your total monthly debt obligations — including the new mortgage — must not exceed 55% of your gross monthly income under the Total Debt Servicing Ratio (TDSR) framework. Banks also stress-test the loan at a higher rate (currently ~4.0%) to ensure you can still afford repayments if rates rise.
