How TDSR and MSR work

TDSR (Total Debt Servicing Ratio) limits all your monthly debt obligations — including the new mortgage, car loans, credit card minimums and personal loans — to 55% of gross monthly income. It applies to all property loans. MSR (Mortgage Servicing Ratio) additionally caps the property loan alone at 30% of income, but only for HDB flats and Executive Condominiums; for HDB/EC the lower (MSR) limit usually binds.

Banks compute the maximum loan by converting your affordable monthly payment into a principal at the 4% medium-term stress rate (5% for non-residential), not your actual package rate. The maximum loan is also capped by the Loan-to-Value limit (up to 75% of property value for a first bank loan), so the binding constraint is the lowest of TDSR, MSR and LTV.

FAQ

Why use 4% and not my real rate?
MAS requires banks to stress-test affordability at a 4% floor so you can still repay if rates rise. This reduces the qualifying loan versus today's lower rates.
Does MSR apply to my condo?
No. MSR applies only to HDB flats and ECs. For private property, only TDSR (and LTV) apply.
How is variable income treated?
Bonuses, commissions and rental income are counted at 70% (a 30% haircut). Enter income after that haircut for an accurate result.
Is the LTV limit included here?
No — this shows the income-based (TDSR/MSR) cap only. Your actual loan is the lower of this and 75% of the property value.
