How the Numbers Work

TDSR
55% of gross monthly income
Total Debt Servicing Ratio. All monthly debt obligations (including the new mortgage, stress-tested) must not exceed 55% of gross income. This is a hard MAS limit for bank loans.
MSR
30% (HDB & EC only)
Mortgage Servicing Ratio. For HDB and EC bank loans, the mortgage instalment alone must not exceed 30% of gross income. A tighter constraint than TDSR for these property types.
Stress Test Rate
4.0% p.a.
MAS requires banks to stress-test affordability at a minimum floor rate of 4.0% p.a. regardless of the actual prevailing loan rate.
Reference Rate (instalment estimate)
3.5% p.a.
The estimated monthly instalment shown uses 3.5% p.a. as a reference (current market ballpark). The max loan calculation uses the 4.0% stress test rate.
LTV (Loan-to-Value)
75% / 45% / 35%
For bank loans: 75% LTV for 1st property, 45% for 2nd, 35% for 3rd+. The down payment floor (5% cash + remainder via CPF) applies for 1st property.
Down Payment Breakdown
1st property: 25% min
At least 5% must be in cash (OTP exercise). The remaining 20% can come from CPF OA. For 2nd property and above, 25% cash downpayment is required (no CPF for down payment on 2nd+).
