Singapore Home Loan Calculator: Understanding TDSR, LTV & MSR
Financing a property in Singapore involves navigating key regulatory frameworks designed to ensure prudent borrowing. The Total Debt Servicing Ratio (TDSR), Loan-to-Value (LTV) limits, and the Mortgage Servicing Ratio (MSR) are the main pillars. This calculator helps you estimate your loan amount, monthly instalment, and check your eligibility against these rules for both HDB concessionary loans and bank loans.
How Your Loan is Calculated
The calculation follows a clear sequence. First, the maximum loan tenure is determined based on the loan type and the borrower's age. For HDB loans, the maximum tenure is 30 years, and the loan must be fully repaid before the borrower's 65th birthday. For bank loans, the maximum tenure is 35 years.
Next, the maximum LTV is set. For HDB loans, it is a flat 80%. For bank loans, it is 75% only if the loan tenure is 30 years or less AND the loan ends before the borrower turns 65. If either condition is not met, the LTV limit drops to 55%. The minimum downpayment is 100% minus the LTV limit.
The loan amount is the property price minus your downpayment. The monthly instalment is calculated using a standard amortisation formula, spreading the principal and interest over the loan's tenure in equal monthly payments.
The Three Key Eligibility Tests
- TDSR (Total Debt Servicing Ratio): Your total monthly debt obligations (including the new home loan instalment, car loans, credit card payments, etc.) must not exceed 55% of your gross monthly income. This applies to all property loans.
- MSR (Mortgage Servicing Ratio): For loans on HDB flats and Executive Condominiums (ECs), the monthly mortgage instalment alone must not exceed 30% of your gross monthly income.
- LTV (Loan-to-Value): The loan amount cannot exceed the percentage of the property's value set by the rules, which depends on the loan type, tenure, and the borrower's age as described above.
You must pass all three tests to be eligible for the loan.
Example: A Couple Buying an HDB Flat
Consider a couple with a combined monthly income of S$9,000, buying a flat valued at S$450,000 with an HDB loan. They plan a 20% downpayment (S$90,000), a 25-year tenure at 2.6% interest, and have existing monthly debts of S$400.
- Loan Amount: S$360,000
- Monthly Instalment: ~S$1,630
- TDSR: (S$1,630 + S$400) / S$9,000 = 22.6% (Pass, under 55%)
- MSR: S$1,630 / S$9,000 = 18.1% (Pass, under 30%)
- LTV: 80% (Pass, meets HDB limit)
They would be eligible for the loan.
Frequent Scenarios and Tips
First-time HDB buyers often use the HDB concessionary loan for its stability. Remember to factor in CPF savings for the downpayment and stamp duty.
Upgraders to private property will use a bank loan. Be mindful that the LTV limit drops to 55% if you take a loan tenure longer than 30 years or if the loan extends past your 65th birthday, requiring a larger downpayment. Also, if you have an existing home loan, the TDSR calculation will include that instalment, making it harder to qualify for a second loan.
Self-employed individuals may need to provide additional documentation of their income for the TDSR assessment.
Next Steps: Documenting Your Loan
Once you have an estimate and are ready to proceed with a formal offer, you will need to formalise the agreement. A Loan Agreement is the comprehensive contract detailing all terms between you and the lender. For simpler commitments, a Promissory Note can serve as evidence of the debt and promise to repay. Using our documents, you can pre-fill key details like the loan amount, interest rate, and repayment schedule to create a draft for review.
