Singapore Mortgage & Affordability Calculator
Estimate your monthly mortgage, stress-test a higher rate and work backwards from income to an indicative maximum property budget.
What Can You Comfortably Finance?
Use Monthly Payment when you already know the property price. Use Maximum Budget when you want to start from income, existing debts and available cash/CPF.
How the Calculator Tests Affordability
For property loans from financial institutions, the planning model limits total monthly debt obligations to 55% of gross monthly income.
For residential property loans, the model tests repayment at the higher of the entered rate or a 4% medium-term floor.
The default LTV is 75%. Actual LTV can be lower because of loan tenure, age, outstanding housing loans, valuation, remaining lease or lender policy.
For HDB-related calculations, the model uses a 30% mortgage-servicing planning cap where applicable.
The HDB concessionary rate is 2.6% p.a. for Jul–Sep 2026. HDB applies its own eligibility and credit assessment.
The calculator also shows a 90% buffered budget. Your own safe budget may be lower after retirement goals, childcare, taxes, maintenance and lifestyle spending.
Read the Result Like an Investor
Your current rate can change. The stressed payment is often more useful than the promotional rate when deciding what feels safe.
A lender's maximum eligible loan is not a recommendation to borrow the maximum. Maintain liquidity and retirement buffers.
Monthly affordability answers “Can I hold it?” The AskAnnaLee property analysis separately asks “Can I exit it profitably?”
Know the Loan. Then Test the Investment.
Mortgage affordability is only one part of a property decision. The next AskAnnaLee tools will calculate stamp duties, rental yield, cash flow and the exit price required to make the investment worthwhile.
Educational estimate only. Rules, bank policies and interest rates change. Verify actual eligibility with HDB and/or your financial institution before committing to a purchase.
