How it works
The rules behind your budget
Singapore has some of the most complex property financing rules in the world. Here's what runs behind the scenes when you calculate.
HDB Loans
MSR — Mortgage Servicing Ratio
Monthly mortgage payment cannot exceed 30% of gross monthly income. Enforced by HDB for all public housing loans.
Bank Loans
TDSR — Total Debt Servicing Ratio
Total monthly debt obligations cannot exceed 55% of gross monthly income. Enforced by MAS across all financial institutions.
Grants
CPF Housing Grants 2026
First-timers can receive up to $120,000 in EHG (families) plus CPF Housing Grant and PHG. Amounts vary by income, flat type, and proximity to parents.

FAQ
Questions everyone asks
With a 4-room resale HDB priced around $500,000, you need roughly $5,500-$6,500/month combined household income for an HDB loan (25-year tenure, no other debts). Your MSR limit of 30% determines your max monthly payment. Use our calculator above with your exact figures.
HDB loans offer a fixed 2.6% rate, 80% LTV, and more lenient credit assessment. Bank loans have variable rates (~2.5-4.0%) but allow higher income earners (no income ceiling). Most first-timers benefit from HDB loans for stability. Our calculator compares both side by side.
For an HDB loan (80% LTV), your entire 20% downpayment can come from CPF OA. For bank loans (75% LTV), 5% must be cash and the remaining 20% can come from CPF. Grants are credited to your CPF OA and count toward your downpayment.
First-timer families can get up to $80,000 (CPF Housing Grant) + $120,000 (Enhanced Housing Grant) + $30,000 (Proximity Housing Grant) = up to $230,000 in total grants. Singles 35+ get half the family amounts. Income ceilings and flat type restrictions apply.
Our calculator uses the latest official MSR (30%), TDSR (55%), HDB interest rate (2.6%), and grant frameworks. However, actual loan approval depends on HDB/bank assessment of your individual financial profile, credit history, and property valuation. Use this as a guide and consult a qualified property advisor for exact figures.
Yes, it's possible. If your CPF OA balance plus grants cover the 20% down payment and stamp duty, and your monthly CPF OA contributions cover the loan instalments, you may not need any cash at all. This is more common with HDB loans (which allow 100% CPF for the down payment) than bank loans (which require 5% in cash). Use our calculator to see your exact CPF vs cash split.
The Mortgage Servicing Ratio (MSR) limits your monthly loan repayment to 30% of your gross monthly income. This applies to all HDB loans and bank loans for HDB properties. For example, with a $6,000 household income, your maximum monthly repayment is $1,800. This is separate from TDSR (55%), which includes all debt obligations.
For HDB loans, the income ceiling is $14,000/month for families and $7,000/month for singles (35+). For Executive Condominiums (EC), the ceiling is $16,000/month. If your household income exceeds these limits, you'll need a bank loan instead (no income ceiling, but higher interest rates and stricter cash requirements).
With an HDB loan, your cash need can be as low as $0 if your CPF OA covers the 20% down payment and stamp duty. With a bank loan, you must pay at least 5% of the property price in cash, plus legal fees (~$3,000). Additional costs like Cash Over Valuation (COV) and renovation also require cash. Our calculator breaks down the exact CPF vs cash split for your situation.
BTO flats are typically 20-40% cheaper than resale flats of the same type and location, but come with 3-5 year waiting times. Resale flats are available immediately and qualify for more grants (CPF Housing Grant + Proximity Housing Grant), which can offset some of the price difference. Use our calculator with the BTO/Resale toggle to compare your affordability for each.
