HDB Max Loan Calculator
Calculate your maximum HDB housing loan eligibility in seconds with our precise calculator
Introduction & Importance of HDB Max Loan Calculator
The HDB Max Loan Calculator is an essential financial tool for Singaporeans looking to purchase public housing through the Housing & Development Board (HDB). This calculator helps potential homebuyers determine their maximum loan eligibility based on HDB’s strict financial guidelines, ensuring they make informed decisions about their housing purchases.
Understanding your maximum loan amount is crucial because:
- It determines your budget for HDB flat selection
- Helps you plan your monthly finances with accurate repayment estimates
- Prevents over-commitment to housing loans that may strain your finances
- Allows you to compare different flat options based on affordability
- Helps in financial planning for other life goals alongside home ownership
According to HDB’s official website, the maximum loan amount is determined by several factors including income, age, existing financial commitments, and the property’s valuation. Our calculator incorporates all these variables to provide the most accurate estimate possible.
How to Use This HDB Max Loan Calculator
Follow these step-by-step instructions to get the most accurate results from our calculator:
-
Enter Your Combined Monthly Income
Input the total gross monthly income of all applicants. This includes basic salary plus any fixed allowances. For variable income (like bonuses), HDB typically considers 70% of the average variable income over the past 12 months.
-
Select Your Loan Tenure
Choose your preferred loan repayment period in years. The maximum tenure is typically 25 years or until the youngest applicant reaches age 65, whichever is shorter. Longer tenures result in lower monthly payments but higher total interest.
-
Input the Current Interest Rate
The default rate is set to HDB’s concessionary rate (currently 2.6% p.a.). You can adjust this if you’re considering different financing options. Note that HDB’s rate is pegged to the CPF Ordinary Account interest rate plus 0.1%.
-
Specify Existing Loan Obligations
Enter any current monthly debt repayments you have (car loans, personal loans, credit card debts, etc.). This affects your Mortgage Servicing Ratio (MSR) calculation.
-
Enter the Property Price
Input the purchase price of the HDB flat you’re considering. For resale flats, this is the agreed purchase price. For BTO flats, use the selling price from HDB.
-
Provide the Youngest Applicant’s Age
This determines the maximum loan tenure you can take, as the loan must be fully repaid by the time the youngest applicant turns 65.

Formula & Methodology Behind the Calculator
Our HDB Max Loan Calculator uses the following financial formulas and HDB guidelines to compute your results:
1. Maximum Loan Amount Calculation
The maximum loan amount is determined by the lower of these two values:
- 90% of Property Price: HDB allows loans up to 90% of the purchase price or valuation (whichever is lower) for first-time applicants buying directly from HDB.
- Income-Based Calculation: Your maximum loan is also limited by your income and financial commitments through the Mortgage Servicing Ratio (MSR).
2. Mortgage Servicing Ratio (MSR)
The MSR is calculated as:
MSR = (Monthly Loan Repayment + Other Property-Related Payments) / Gross Monthly Income × 100%
HDB’s current MSR limit is 30% of your gross monthly income. Our calculator ensures your loan doesn’t exceed this ratio.
3. Monthly Repayment Calculation
We use the standard amortization formula to calculate monthly repayments:
Monthly Payment = P × (r(1+r)^n) / ((1+r)^n - 1)
Where:
- P = Loan principal amount
- r = Monthly interest rate (annual rate divided by 12)
- n = Total number of payments (loan tenure in years × 12)
4. Loan Tenure Calculation
The maximum loan tenure is the lesser of:
- 25 years, or
- 65 minus the youngest applicant’s age
5. Total Interest Calculation
Total interest is calculated as:
Total Interest = (Monthly Payment × Total Payments) - Loan Amount

-
Time Your Application Strategically
