How Singapore Mortgages Work
Singapore mortgages are regulated by MAS (Monetary Authority of Singapore) with several key rules that affect how much you can borrow and what your monthly payment will be.
Loan-to-Value (LTV) Limits
- First housing loan: Up to 75% LTV (bank loan) or 80% (HDB loan for HDB flats). Reduced to 55% if loan tenure exceeds 30 years or extends past age 65.
- Second housing loan: Up to 45% LTV. Reduced to 25% if loan tenure exceeds 30 years or extends past age 65.
- Third and subsequent loans: Up to 35% LTV. Reduced to 15% if loan tenure exceeds 30 years or extends past age 65.
Source: MAS Notice 632 (residential property loans).
TDSR. Total Debt Servicing Ratio
Your total monthly debt obligations (including the new mortgage, car loans, credit cards minimum payments, personal loans, etc.) cannot exceed 55% of your gross monthly income. This is calculated at a stress test rate (currently 4% for residential property loans) to ensure you can still service the loan if rates rise.
MSR. Mortgage Servicing Ratio (HDB / EC only)
For HDB flats and Executive Condominiums from developers, your mortgage payment cannot exceed 30% of gross monthly income. This is stricter than TDSR and often limits how much HDB buyers can borrow even when their total debt is well within TDSR.
Minimum Cash Downpayment
Regardless of CPF balance, a minimum 5% of the purchase price must be paid in cash (for first-time buyers with max 75% LTV). The remainder of the downpayment can be paid from CPF Ordinary Account or cash. For lower LTV loans, the minimum cash requirement is higher.
What Drives Your Monthly Payment
- Loan amount (principal). The property price minus your downpayment. Bigger property or smaller downpayment = bigger loan = higher monthly payment.
- Interest rate. The annualised cost of borrowing. A 1% rate change on a $1M loan is roughly $500/month difference.
- Loan tenure. Length of the loan in years. Longer tenure = lower monthly payment but much higher total interest paid.
- Loan type. Fixed rate (predictable), floating rate (SORA-pegged, variable), or hybrid. Each has trade-offs.
Additional Costs Beyond the Mortgage
Monthly mortgage isn't your only recurring cost. Budget for:
- Maintenance / condo fees, $300-$1,000+/month for condos; $80-$200/month for HDB
- Property tax. Paid annually; owner-occupier rates are progressive starting 0% on the first $12,000 of Annual Value
- Mortgage insurance. Reducing-term life insurance to cover the loan if you pass away (~$30-$100/month depending on age and amount)
- Fire insurance. Typically $15-$40/month, often bundled with the loan
- Utilities, internet, SP services. Varies by household usage
Frequently Asked Questions
How is monthly mortgage calculated?
Monthly mortgage payment is calculated using the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n - 1], where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments. The calculator handles this automatically. Just enter property price, downpayment, interest rate, and loan tenure.
What's the maximum loan I can get in Singapore?
For residential property: LTV (Loan-to-Value) is capped at 75% for your first housing loan, 45% for your second, and 35% for your third onwards. However, actual approval depends on TDSR (Total Debt Servicing Ratio capped at 55% of gross monthly income) and, for HDB/EC loans, MSR (Mortgage Servicing Ratio capped at 30%).
What interest rate should I use?
As of April 2026, Singapore mortgage rates are in the ~1.4-2.5% range for fixed packages, with SORA-pegged floating packages tracking 3-month compounded SORA (~1.2% as at late 2025) plus a bank spread of 0.5-0.8%. Exact rates vary by bank, lock-in period, and your loan profile. Regardless of the actual rate, MAS requires banks to apply a 4% stress test rate in the TDSR calculation to ensure affordability if rates rise. Always check current SORA at the MAS eService and current bank packages before committing.
How do I lower my monthly payment?
Three main levers: (1) Longer loan tenure (max 35 years for private, 25 for HDB) reduces monthly payment but increases total interest. (2) Larger downpayment reduces the principal. (3) Lower interest rate via refinancing or better loan package. Each has trade-offs. Talk to a mortgage broker or Jet about what's optimal for your situation.
What's included in monthly mortgage vs total housing cost?
This calculator shows principal + interest only. Your total monthly housing cost also includes: maintenance/condo fees ($300-800+ for condos, $80-200 for HDB), property tax (for owner-occupier: progressive rates starting from 0% on AV up to $12K), insurance (mortgage reducing term + fire insurance, ~$50-150/month), and utilities. Budget at least an extra 15-20% on top of the mortgage for these costs.
Can I use CPF for my mortgage?
Yes. CPF Ordinary Account (OA) can be used for downpayment (at least 5% must be cash, the rest can be CPF), monthly repayments, and stamp duty. Usage is capped at the Valuation Limit and Withdrawal Limit based on property age, tenure, and age of owner. CPF used must be refunded with accrued interest when you sell.
How much is the monthly payment on a $1.5 million condo in Singapore?
At 75% LTV, your loan is $1.125M. At current fixed rates (~1.5% p.a.) over 25 years, monthly payment is roughly $4,500. At 2.5%, roughly $5,050. At the 4% stress test rate, roughly $5,930. Add maintenance fees ($300-800/mo) and property tax for total housing cost. Use the calculator above with your actual numbers.
Should I take a fixed or floating rate mortgage in Singapore?
Fixed rates (currently ~1.4-2.5%) lock your payment for 2-3 years, giving predictability. Floating rates (SORA-pegged, currently ~1.0-1.5% all-in) are cheaper now but can rise. Most buyers take fixed for the first 2-3 years, then refinance. If you plan to sell within 3-5 years, floating may save you money. If holding long-term, fixed gives peace of mind. Always compare at least 3 bank packages.
