HDB Affordability Calculator (2026)
Find out how much HDB flat you can afford based on your household income, CPF savings, and eligible grants.
What is the HDB Affordability Calculator?
This calculator estimates the maximum HDB flat price you can afford based on your household income, CPF OA savings, and eligible housing grants. It factors in the 30% MSR rule, HDB loan terms at 2.6% p.a., and up to 80% LTV to determine your purchasing power.

How HDB Affordability Is Calculated
Your maximum HDB purchase price depends on three factors: loan amount (based on MSR and loan tenure), CPF OA savings, and housing grants you qualify for.
The Mortgage Servicing Ratio (MSR) caps your monthly loan repayment at 30% of gross monthly income for HDB loans. This determines the maximum loan you can take, which is then added to your CPF OA balance and eligible grants to arrive at your affordable price.
With an HDB loan, you can borrow up to 80% LTV (Loan-to-Value) over a maximum tenure of 25 years at the concessionary interest rate of 2.6% p.a. The remaining 20% downpayment can be paid entirely from CPF OA.
Step 1: MSR Check
Maximum monthly instalment = 30% of gross monthly household income
Step 2: Maximum Loan
Calculate max loan from MSR instalment, 2.6% interest rate, and up to 25-year tenure
Step 3: Add CPF OA
Your CPF Ordinary Account savings can cover the 20% downpayment and more
Step 4: Add Grants
EHG up to $120,000 + CPF Housing Grant + Proximity Grant further increase your budget
Frequently Asked Questions
What is the income ceiling for buying an HDB flat?expand_more
The gross monthly household income ceiling for purchasing a new HDB flat (BTO) is $14,000. For Executive Condominiums (EC), the income ceiling is $16,000. Singles buying under the Single Singapore Citizen Scheme have a ceiling of $7,000. These ceilings apply to the combined gross monthly income of all applicants and occupiers listed in the application.
What is the MSR 30% rule for HDB loans?expand_more
The Mortgage Servicing Ratio (MSR) limits your monthly HDB loan instalment to 30% of your gross monthly income. For example, if your household earns $8,000 per month, your maximum monthly repayment is $2,400. This applies only to HDB loans — bank loans for HDB flats are subject to the TDSR limit of 55% instead.
Can I use CPF to pay for my HDB flat?expand_more
Yes, you can use your CPF Ordinary Account (OA) savings to pay for your HDB flat. CPF OA can be used for the downpayment (up to 20% of the purchase price with an HDB loan), monthly mortgage instalments, stamp duty, and legal fees. However, there is a CPF usage limit — the total CPF used cannot exceed the Valuation Limit (VL) plus the current balance in your OA.
How much downpayment do I need for an HDB flat?expand_more
For an HDB loan, the minimum downpayment is 20% of the purchase price, which can be fully paid using CPF OA savings. For a bank loan, the minimum downpayment is 25% — with at least 5% in cash and the remaining 20% payable by CPF OA or cash. First-time buyers with lower incomes may also receive grants that reduce the effective downpayment.
What grants are available for first-time HDB buyers?expand_more
First-time Singapore citizen buyers may qualify for the Enhanced CPF Housing Grant (EHG) of up to $120,000 based on household income, the CPF Housing Grant of $50,000 to $80,000 for BTO or resale flats, and the Proximity Housing Grant (PHG) of up to $30,000 if buying near parents or married children. These grants directly reduce the purchase price.
