How lenders in Singapore assess affordability
MAS limits total monthly debt repayments to 55% of gross monthly income (TDSR). For an HDB flat, or an executive condominium whose minimum occupation period has not ended, mortgage repayments are also capped at 30% of gross monthly income (MSR).

Financial institutions work out these ratios at an interest rate of at least 4% for residential property loans, and count at most 70% of variable income such as bonuses or rental income.

OwnerCost's 28% of gross income is its own planning ceiling for monthly owner cost. It is not the TDSR or MSR.

How we calculate
