Total Debt Servicing Ratio Calculator
Total Debt Servicing Ratio (TDSR) measures how much of your gross monthly income is used to repay all your monthly debt obligations, including your property loan, car loan, personal loans and other outstanding debts.
In Singapore, the current TDSR threshold is generally 55% of gross monthly income.
If your gross monthly income is $10,000, your total monthly debt commitments should generally not exceed:
*If you are already paying $1,500 per month for a car loan and other debts, this leaves up to $4,000 per month for the assessed property loan repayment, subject to the lender’s credit assessment.
Mortgage Servicing Ratio (MSR) measures how much of your gross monthly income can be used specifically for your housing loan repayment. It applies to housing loans for HDB flats and Executive Condominiums where the MSR requirement applies.
The current MSR limit is 30% of gross monthly income.
If your gross monthly income is $10,000, your maximum monthly housing loan repayment under MSR would generally be:
*This means the assessed monthly mortgage repayment should generally not exceed $3,000, even if you have sufficient room under the TDSR limit.
Total Debt Servicing Ratio (TDSR) considers your overall monthly debt obligations, which may include:
The purpose of TDSR is to assess your total debt burden rather than looking only at your new mortgage.
TDSR (Total Debt Servicing Ratio) measures your total monthly debt obligations against your gross monthly income. This includes your proposed home loan as well as other debts such as car loans, personal loans, credit card obligations and existing property loans. The current TDSR threshold is 55% of gross monthly income.
MSR (Mortgage Servicing Ratio) is more specific. It looks only at the monthly repayment for the housing loan and is capped at 30% of gross monthly income.
Unlike TDSR, which generally applies to property loans granted by financial institutions, MSR only applies to housing loans for the purchase of HDB flats and Executive Condominium (EC) units purchased directly from developers. It does not generally apply when purchasing a private condominium or landed property.
For property purchases where MSR applies, borrowers may need to meet both the 30% MSR limit and the applicable TDSR requirements. This means that even if your total debt falls within the TDSR limit, the amount you can borrow may still be restricted if your monthly housing instalment exceeds the MSR limit.
For example, if your gross monthly income is S$10,000, your monthly housing loan repayment would generally need to stay within S$3,000 under the 30% MSR limit, while your overall debt obligations would separately be assessed under TDSR.
Understanding your borrowing capacity before committing to a property can help you plan your purchase more confidently. By checking your estimated TDSR in advance, you can:
A few minutes spent checking your estimated affordability upfront can help you make a more informed property purchase and reduce potential delays during the home loan application process.
If your TDSR exceeds 55%, the loan amount you qualify for may be reduced. You can consider reducing your existing debts, lowering the property loan amount, choosing a more affordable property or improving your assessable income before applying. MAS sets the TDSR threshold at 55%, although financial institutions may have limited circumstances where loans above the threshold can be granted under the applicable rules.
You may also use our TDSR Calculator to estimate how much changes to your income, existing financial commitments or desired loan amount could affect your home loan eligibility.
Yes, but your credit score is not part of the TDSR formula itself. TDSR measures your monthly debt obligations against your gross monthly income, while your credit history helps lenders assess your overall creditworthiness and repayment behaviour.
Even if you meet the 55% TDSR requirement, the bank will still conduct its own credit assessment before approving your home loan. A weaker credit profile, such as a history of late payments or other credit concerns, may therefore affect your loan approval or the amount the bank is prepared to offer.
