Enter your gross monthly household income, existing debts, household type, and tenure. This checks the HDB loan income ceiling, runs the MSR (30%) and TDSR (55%) caps, and shows the maximum HDB flat you can afford — stress-tested at a 4% medium-term rate, with the actual repayment at the 2.6% HDB concessionary rate.

An HDB concessionary loan (2.6% p.a.) is for HDB flats only — not private condos, and not Executive Condominiums, which use bank loans. To take an HDB loan your gross monthly household income must be below the income ceiling, and you must meet citizenship and other eligibility conditions (confirmed via an HDB Flat Eligibility, or HFE, letter — this calculator does not model those non-income conditions). On top of the ceiling, your repayment has to fit inside two ratios at once: the Mortgage Servicing Ratio and the Total Debt Servicing Ratio.
Singapore specifics: The MSR caps your monthly home-loan repayment at 30% of gross income and applies only to HDB flats and ECs. The TDSR caps all your monthly debt at 55% of gross income and applies to every property type. Whichever cap is lower is the one that binds. The HDB concessionary loan covers up to 75% of the flat's value (lowered from 80% in August 2024), so you need at least a 25% down payment. Affordability is stress-tested at a 4% medium-term interest-rate floor set by MAS, even though the actual HDB loan rate is 2.6% — so the loan you qualify for is based on 4%, and your real monthly payment at 2.6% is lower. Income-ceiling figures are as of 2026; always confirm the current numbers with HDB.

An HDB concessionary loan (currently 2.6% p.a.) is for HDB flats only and has a gross monthly household income ceiling — around S$14,000 for families, S$7,000 for singles on the 35+ scheme, and S$21,000 for extended/multi-generation households as of 2026 (confirm the current figures with HDB). You also need to meet citizenship and other eligibility conditions and obtain an HDB Flat Eligibility (HFE) letter, and your repayment must fit within the Mortgage Servicing Ratio (MSR, 30% of gross income) and the Total Debt Servicing Ratio (TDSR, 55%).
As of 2026 the gross monthly household income ceiling for an HDB concessionary loan is approximately S$14,000 for families, S$7,000 for singles buying under the 35+ scheme, and S$21,000 for extended or multi-generation households. These figures change over time — always confirm the current ceiling with HDB. If your income exceeds the ceiling you can still buy an HDB flat, but you would finance it with a bank loan rather than the HDB loan.
The Mortgage Servicing Ratio (MSR) caps your monthly home-loan repayment at 30% of gross monthly income and applies only to HDB flats and Executive Condominiums. The Total Debt Servicing Ratio (TDSR) caps all of your monthly debt repayments — the new mortgage plus car, renovation, student loans and credit-card minimums — at 55% of gross monthly income and applies to all property. For an HDB flat you must pass both; whichever cap is lower is the binding one.
Take the lower of the MSR cap (30% of gross income) and the TDSR cap (55% of gross income minus existing debts) as your maximum monthly repayment. Convert that to a maximum loan using the 4% medium-term stress rate over your chosen tenure (up to 25 years for an HDB loan), then divide by 0.75 because the HDB loan covers up to 75% of the flat’s value. The remaining 25% is your down payment. This calculator does the arithmetic for you.
The HDB concessionary loan interest rate is 2.6% per annum, pegged at 0.1% above the prevailing CPF Ordinary Account interest rate. Even though your actual repayment is calculated at 2.6%, eligibility and affordability are stress-tested against a higher 4% medium-term interest-rate floor set by MAS, so the loan you qualify for is based on the 4% figure, not 2.6%.
