HDB Affordability Calculator
Estimate how much you can borrow, check MSR & TDSR limits, monthly repayments, and affordable property price in minutes.
Why use a HDB affordability calculator?
Planning to buy your first HDB flat or resale home in Singapore?
Use this HDB affordability calculator to understand exactly how much you can afford before committing to a purchase.
By taking into account your income, age, existing loans, CPF savings, and eligible government grants, the tool calculates your maximum loan amount, required down payment, and estimated monthly repayment. It also checks key housing rules such as the Mortgage Servicing Ratio (MSR), Total Debt Servicing Ratio (TDSR), loan tenure, and LTV limits, so you can see any shortfall and make informed decisions.
Avoid surprises, plan your budget effectively, and gain confidence in your home-buying journey with Lendela’s easy-to-use HDB affordability calculator.
How this HDB affordability calculator works
This calculator evaluates your affordability in three clear steps:
Assess your borrowing capacity
It calculates your maximum loan tenure and loan amount based on your age, income mix, loan type, and regulatory limits such as MSR and TDSR.
Calculate what the property requires
Based on the property price and estimated grants, it works out the required loan amount, minimum downpayment, and expected monthly repayment.
Compare affordability vs requirement
The results show whether you can afford the property, and if not, exactly what is limiting you — such as loan size, upfront cash, or monthly repayment.
All calculations are based on standard mortgage formulas and Singapore housing regulations.
Frequently Asked Questions
For HDB housing loans issued on or after 20 August 2024, the maximum Loan-to-Value (LTV) limit is up to 75% of the purchase price or market valuation — whichever is lower.
The remaining 25% must be paid as your downpayment, subject to HDB eligibility conditions.
For bank home loans in Singapore (including HDB flats and Executive Condominiums), the maximum LTV is up to 75%, subject to MAS regulations and the bank’s credit assessment.
Your final approved loan amount depends on factors such as income, credit score, MSR and TDSR.
The HDB concessionary loan interest rate is pegged at CPF Ordinary Account (OA) rate + 0.10%, and is reviewed quarterly.
In recent years, this has remained at 2.6% per annum, but it may change if the CPF OA rate is revised.
Eligible first-timer families buying an HDB resale flat may receive up to $230,000 in CPF housing grants, depending on income and eligibility criteria:
Enhanced CPF Housing Grant (EHG): Up to $120,000
CPF Housing Grant: Up to $80,000
Proximity Housing Grant (PHG): Up to $30,000
All housing grants are subject to HDB eligibility requirements and income ceilings.
For BTO flats, the downpayment is typically paid at the Agreement for Lease signing.
For resale flats, part of the downpayment is paid upon exercising the Option to Purchase (OTP), with the balance due at completion. Your housing loan will only be disbursed closer to key collection or completion.
To secure an HDB or bank housing loan, you must meet both the Mortgage Servicing Ratio (MSR) and Total Debt Servicing Ratio (TDSR) requirements.
If your MSR passes but TDSR fails, you may need to:
Reduce existing debt obligations (e.g. credit cards or personal loans)
Adjust your loan tenure (if eligible)
Consider a lower property price
Banks will only approve your home loan if both MSR and TDSR thresholds are met.
