Calculate how much HDB flat you can afford based on MSR, TDSR, and available grants.
Every HDB flat purchase in Singapore is capped by two separate debt-servicing ratios, and your maximum loan is whichever one bites first. The Mortgage Servicing Ratio (MSR) limits your home loan repayment — for this flat alone — to 30% of your gross monthly income, and applies only to HDB flats and executive condominiums. The Total Debt Servicing Ratio (TDSR) is broader: it caps all your monthly debt repayments, including this home loan, at 55.00000000000001% of gross monthly income, and applies to every property purchase in Singapore regardless of type.
This calculator computes the maximum loan allowed under each ratio separately, then takes the lower of the two — exactly as HDB and banks do when assessing your loan. If you have significant existing debts (car loans, credit cards, personal loans), TDSR often becomes the binding constraint even though MSR is the HDB-specific rule, because your other obligations eat into the 55% ceiling before the home loan is even added.
The maximum loan-to-value (LTV) ratio is 75% for an HDB loan and 75%for a bank loan under this calculator's simplified first-housing-loan assumption, meaning you'll need to fund the remaining portion through CPF Ordinary Account savings and/or cash. Loan tenure is capped at 25 years for HDB loans and 30 years for bank loans, and a longer tenure lowers your monthly instalment but increases total interest paid over the life of the loan.
The EHG is a tiered grant for eligible first-timer buyers that phases out as household income rises. Families with monthly income up to $1,500 qualify for the maximum grant of $120,000, tapering down in steps to $45,000 for families earning up to $9,000 a month, above which no EHG applies. Singles face the same taper structure at half the grant amounts — from $60,000 down to $30,000 for incomes up to $4,500 a month. This calculator applies the tier matching the household income you enter, and adds any applicable CPF Housing Grant or Proximity Housing Grant on top for resale-flat first-timers.
This tool provides educational estimates only, not licensed financial or mortgage advice. Actual loan eligibility, grant amounts, and interest rates depend on your full credit profile, the specific flat, prevailing bank rates, and HDB's final assessment. Consult HDB or a bank loan officer before committing to a purchase.

MSR (Mortgage Servicing Ratio) caps home loan repayments at 30% of gross monthly income and applies only to HDB flats and executive condominiums. TDSR (Total Debt Servicing Ratio) caps all debt repayments — including the home loan — at 55% of gross monthly income and applies to every property purchase.
Whichever is more restrictive for your income and existing debts. This calculator computes both and uses the lower (binding) loan amount, exactly as banks and HDB do.
EHG is available to eligible first-timer families and singles buying a resale flat (or new flat, subject to conditions), with the grant amount tapering down as household income rises. This calculator estimates your EHG based on the income tiers you enter.
