Buying an HDB flat involves understanding affordability limits set by MSR and TDSR as well as the difference between an HDB concessionary loan and a bank loan. This calculator estimates monthly repayments, total interest payable and the minimum income required to qualify for both HDB loans (2.6%) and bank loans (from 1.50%). It also factors in the key differences: HDB loans offer up to 80% LTV with no cash down payment required while bank loans offer lower rates but require 5% cash and cap LTV at 75%. 

Use this tool to compare both options side by side before deciding which financing route makes more sense.

More Details

An HDB concessionary loan is financing provided directly by HDB for Singapore Citizens buying HDB flats. The interest rate is pegged at 0.1% above the CPF Ordinary Account rate which currently sits at 2.6% p.a. HDB loans offer up to 80% LTV, no lock-in period and allow 100% CPF for the down payment.

Mortgage Servicing Ratio (MSR) limits home loan repayments to 30% of gross monthly income. It applies to all HDB flats and EC purchases both HDB loans and bank loans. Banks use a 4% stress test rate when calculating MSR which reduces maximum borrowing capacity.

▸ HDB loan:
2.6% fixed, 80% LTV, no lock-in and no cash required.
▸ Bank loan:
From 1.50%, 75% LTV, 2-year lock-in, 5% cash required. Bank loans are currently cheaper but come with rate fluctuation risk and less flexibility.

Maximum loan depends on income (MSR 30%), property price and LTV limit (80% HDB / 75% bank). For a $500,000 flat with $10,000 income, maximum loan is approximately $450,000 to $480,000 depending on loan type and tenure.

Bank Rates Are Now Lower But Is Switching Right for Everyone?

With bank rates at 1.50% to 1.75% versus HDB's 2.6% savings are significant, roughly $200 per month on a $400,000 loan. However, HDB loans offer stability, no lock-in and the flexibility to refinance later without penalty.

For first time buyers unsure about rate movements, starting with an HDB loan keeps options open. For those confident in their finances and comfortable with a 2-year lock-in, a bank loan delivers substantial savings. Our calculator helps compare both scenarios side by side.: Quote Icon

How to Use Our HDB Loan Calculator (FAQs)

What loan amount should I enter?

Enter the amount being borrowed not the property price. For HDB loans this is up to 80% of the property price. For bank loans, up to 75%. Subtract the down payment from property price to get the loan amount.
For HDB concessionary loans use 2.6% which is the current fixed rate. For bank loans use the rate offered by the bank typically 1.50% to 2.00% for fixed rates in 2026. Check current rates before calculating.
Maximum tenure is 25 years for HDB loans or 30 years for bank loans but cannot extend beyond age 65. Longer tenure means lower monthly payments but more total interest paid.
The calculator uses a standard amortisation formula that spreads the loan evenly across all months while accounting for interest. Each payment covers both interest and principal.
This calculator provides estimates only actual offers depending on credit score, income verification, property valuation and bank specific policies.
The calculator shows total monthly repayment. How much comes from CPF versus cash depends on individual CPF balances and personal preference.

An HDB loan calculator helps compare repayments between an HDB concessionary loan at 2.6% and bank loan options but the right choice depends on more than just monthly payments. For home buyers leaning toward a bank loan our home loans page compares rates from 15+ banks including fixed and floating packages for HDB flats, private properties and Executive Condos. Our mortgage calculator provides broader affordability estimates based on different loan amounts, interest rates, and tenures.

Existing HDB homeowners already on a bank loan and approaching the end of their lock-in period can explore refinancing to potentially secure a lower rate.
