TDSR (Total Debt Servicing Ratio) in Singapore: Everything Property Buyers Need to Know

Reading Time: 5 minutes

If you’re buying a home in Singapore, one of the most important rules that determines how much you can borrow is the TDSR (Total Debt Servicing Ratio).

Implemented by the Monetary Authority of Singapore (MAS), TDSR ensures borrowers don’t take on more debt than they can handle — promoting long-term financial stability and preventing a property bubble.

Whether you’re applying for a home loan, refinancing your mortgage, or planning to buy an investment property, understanding TDSR (Total Debt Servicing Ratio) is crucial to your financing strategy in 2025.

What Is TDSR (Total Debt Servicing Ratio)?

TDSR (Total Debt Servicing Ratio) is a mortgage lending framework introduced by MAS in 2013 to ensure that borrowers do not overextend themselves financially.

It limits the portion of a borrower’s gross monthly income that can go toward debt repayments — including home loans, car loans, credit cards, and personal loans.

In simple terms:

TDSR = (Total monthly debt obligations ÷ Gross monthly income) × 100%

TDSR (Total Debt Servicing Ratio) Limit in Singapore

As of 2025, the TDSR limit in Singapore remains at 55%.

That means your total monthly loan repayments (including housing, car, credit, and other debts) cannot exceed 55% of your gross monthly income.

Example:
If you earn S$10,000 per month, your total monthly debt obligations cannot exceed S$5,500.

This rule ensures borrowers have enough income left for daily living expenses and future financial stability.

Why TDSR Was Introduced

The TDSR (Total Debt Servicing Ratio) was launched by the Monetary Authority of Singapore (MAS) on 29 June 2013 to curb rising household debt and speculative property purchases.

Before TDSR, many buyers stretched their finances thin to buy multiple properties, assuming property prices would always rise.

TDSR changed that by forcing both banks and borrowers to adopt responsible lending practices.

How TDSR (Total Debt Servicing Ratio) Works

When assessing your loan application, banks calculate your TDSR ratio by considering:

1. Gross Monthly Income
   • Includes salary, rental income, bonuses, dividends, etc.
   • For variable income, banks typically apply a 30% haircut to account for fluctuations.
2. Monthly Debt Obligations
   • Mortgage repayments (including new loan)
   • Car loans, student loans, and personal loans
   • Credit card minimum payments (usually 3% of outstanding balance)
   • Hire purchase or renovation loans
3. Stress-Tested Interest Rate
   • MAS requires banks to calculate mortgage payments using a medium-term interest rate (currently 4% for residential loans) even if your actual loan package offers a lower rate.
4. Loan Tenure
   • The longer the loan tenure, the smaller your monthly repayment — but interest costs will be higher over time.

Example of TDSR Calculation

Let’s say:

• Gross monthly income: S$12,000
• Existing car loan: S$800/month
• Credit card debt: S$300/month
• Proposed mortgage repayment: S$4,200/month

Total debt = S$800 + S$300 + S$4,200 = S$5,300

TDSR = (S$5,300 ÷ S$12,000) × 100% = 44.2%

✅ Since 44.2% < 55%, the buyer meets the TDSR requirement.

TDSR vs MSR (Mortgage Servicing Ratio)

While both relate to loan eligibility, TDSR and MSR are different.

In short, TDSR is broader, while MSR is more targeted at HDB and EC buyers.

Exceptions and Exemptions from TDSR

MAS allows some flexibility under specific circumstances.

1. Refinancing Owner-Occupied Properties

Borrowers refinancing their own home are exempted from the 55% TDSR limit if:

• They bought the property before 29 June 2013, and
• They are not taking on additional loan amounts.

2. Refinancing Investment Properties

Investment property refinancing is allowed above the 55% limit only if:

• The borrower commits to a repayment plan to reduce TDSR to 55% within a set period.

3. Bridging Loans

Temporary bridging loans — often used when buying a new property before selling an existing one — may be partially exempted from TDSR if backed by sale proceeds.

How to Improve Your TDSR Ratio

If your TDSR exceeds 55%, you may need to improve your financial standing before banks approve your loan.

Here are some strategies:

1. Reduce existing debt — pay off personal or car loans.
2. Increase income — include rental income or bonuses (with supporting documents).
3. Add a co-borrower — combining incomes can help lower TDSR percentage.
4. Extend loan tenure — lowers monthly repayment amount, thus improving TDSR.
5. Avoid multiple credit cards or overdrafts — these inflate your debt profile.

How TDSR Affects Property Buyers in Singapore

The TDSR framework impacts every aspect of property financing:

1. First-Time Home Buyers

TDSR ensures you buy within your means. Even if you qualify for a large loan, banks will cap borrowing to keep your total debt under 55% of your income.

2. Property Investors

For investors, TDSR restricts leveraging on multiple properties, ensuring stable financial exposure. It also prevents speculative buying sprees.

3. High-Income Earners

While high earners can take larger loans, TDSR still applies equally. So, your total monthly debt payments cannot exceed 55% of your income — regardless of wealth.

Documents Needed for TDSR Assessment

To calculate TDSR (Total Debt Servicing Ratio), banks require:

• Latest 3 months’ payslips
• CPF contribution history (12 months)
• Income tax notice of assessment (NOA)
• Employment contract or company letter (for variable income)
• Loan statements for existing debt obligations

Having these ready speeds up loan processing and ensures accurate assessment.

Impact of TDSR on Property Prices in Singapore

Since its introduction, TDSR has helped maintain a healthy balance in Singapore’s property market by:

• Curbing over-leverage among investors
• Reducing default risks during interest rate hikes
• Encouraging responsible borrowing
• Stabilizing property demand and price growth

TDSR complements other cooling measures like ABSD (Additional Buyer’s Stamp Duty) and LTV (Loan-to-Value) limits to ensure long-term market sustainability.
