TDSR Calculator (2026)
Check if you meet Singapore's 55% Total Debt Servicing Ratio limit for property loans.
What is the Total Debt Servicing Ratio (TDSR)?
The TDSR is a framework set by MAS that limits your total monthly debt repayments to 55% of your gross monthly income. It ensures borrowers do not overextend themselves when taking on property loans, and applies to all property purchases in Singapore.

Quick Reference
- • TDSR limit: 55% of gross monthly income (all debts including new property loan)
- • MSR limit: 30% of gross monthly income (HDB and EC from developers only)
- • Stress-test rate: 4% p.a. or actual rate, whichever is higher
- • Credit card debt counted at 3.5% of outstanding balance for TDSR
Who This Calculator Is For
Understanding TDSR and MSR helps you plan your property purchase and loan eligibility before approaching a bank.
Home Loan Applicants
TDSR limits total monthly debt obligations (all loans combined) to 55% of gross monthly income. This determines your maximum home loan.
- •TDSR cap: 55% of gross monthly income
- •Includes: home loan + car loan + personal loans + credit card minimums
- •Calculated by banks: before approving mortgage
- •Stressed interest rate: used for variable-rate loans
HDB Flat Buyers (MSR also applies)
HDB flat buyers face an additional Mortgage Servicing Ratio (MSR) limit of 30% for the housing loan specifically.
- •MSR: max 30% of gross income on housing loan only
- •MSR applies to: HDB flats and executive condos (EC)
- •MSR is stricter: than TDSR for first-time HDB buyers
- •TDSR (55%): applies across ALL loans
Borrowers with Multiple Debts
Existing car loans, personal loans, and credit card balances reduce your TDSR headroom and lower your maximum home loan.
- •Car loan: typically $1,000–$2,000/month
- •Minimum credit card payment: 3% of outstanding balance
- •Clear debts before applying: to maximise loan
- •Joint application: adds incomes but also combined debts
How TDSR and MSR Work
The Total Debt Servicing Ratio (TDSR) framework was introduced by MAS to ensure borrowers do not overextend themselves. Your total monthly debt repayments (including the new property loan) must not exceed 55% of your gross monthly income.
For HDB flats and ECs purchased from developers, an additional Mortgage Servicing Ratio (MSR) of 30% applies. MSR considers only the property loan instalment, not other debts. You must satisfy both TDSR and MSR to qualify.
Banks use a stress-tested interest rate (currently 4% p.a. or the actual rate, whichever is higher) when computing TDSR. This ensures you can still afford repayments even if interest rates rise in the future.

TDSR vs MSR: What's the Difference?
Both ratios protect borrowers from over-leveraging, but they measure different things and apply to different property types.
| Ratio | What It Measures | Cap | Applies To |
|---|---|---|---|
| TDSR | All monthly debt repayments ÷ gross monthly income | 55% | All property types |
| MSR | Housing loan repayment only ÷ gross monthly income | 30% | HDB flats and ECs only |
| Key difference | TDSR covers ALL debts; MSR covers only the new housing loan | — | If buying HDB, both must be met |
Frequently Asked Questions
What is the TDSR limit in Singapore?expand_more
The Total Debt Servicing Ratio (TDSR) limit in Singapore is 55%. This means your total monthly debt obligations — including the new property loan, existing loans, credit card minimum payments, and other commitments — cannot exceed 55% of your gross monthly income.
What is the difference between TDSR and MSR?expand_more
The MSR (Mortgage Servicing Ratio) is an additional limit of 30% that applies specifically to HDB flats and Executive Condominiums purchased directly from developers. MSR caps the portion of income that goes toward the property loan only (excluding other debts). You must meet both TDSR (55%) and MSR (30%) when buying an HDB flat with a bank loan.
What counts as debt when calculating TDSR?expand_more
All existing monthly debt obligations are included: property loan repayments, car loan instalments, personal loan repayments, student loan payments, credit card minimum payments (typically 3.5% of outstanding balance), renovation loan repayments, and any other recurring financial commitments reported to credit bureaus.
How is income calculated for TDSR?expand_more
For salaried employees, gross monthly income includes your basic salary plus any fixed allowances. Variable income (bonuses, commissions, overtime) is typically haircut by 30%. For self-employed individuals, income is based on the latest 2 years of tax assessments, with the lower figure used. Rental income from investment properties is usually haircut by 20-30%.
