What can you afford?

Your maximum loan and property price, based on MAS's own borrowing rules. This tool applies the 55% cap on your total monthly debt, the extra 30% cap on your loan repayment alone for HDB flats and new ECs, the 4% stress test rate, the 30% cut on bonus income, and the age limit on your loan tenure. It also shows the upfront cash you'll need on top of the loan.

How the limit is found

Assessable income = fixed salary + 70% of bonus ÷ 12. The bank applies the stricter of TDSR (55% of income minus debts) and, for HDB/new EC, MSR (30% of income). That monthly cap, tested at the stress test rate over your tenure, sets your maximum loan. Price = loan ÷ 75% LTV. Tenure runs up to 30 years for private/EC or 25 for HDB — or until you turn 65, whichever is shorter.

Which rules set your maximum loan?

The table below breaks down all four rules.

The four MAS rules this calculator applies, and what each one does to your maximum loan. Rates and thresholds verified 12 Jul 2026.
RuleThe limitWho it applies toWhat it does to your loan
Total Debt Servicing Ratio (TDSR)55% of incomeEvery property buyerCaps all your monthly debt, including the new mortgage
Mortgage Servicing Ratio (MSR)30% of incomeHDB flats and new ECs onlyCaps the mortgage alone — usually the stricter of the two limits
Stress test rate4% per annumEvery residential loanSizes the loan at 4%, no matter how low your actual rate is
Loan tenure capUp to 30 years, and must be repaid by age 65 (25 years for HDB)Every residential loanShortens your maximum loan term, which cuts how much you can borrow

Two of these four rules matter more than expected. The 4% stress test rate sets your maximum loan, even if your actual mortgage rate is lower or market rates fall. The loan tenure cap usually makes the biggest difference. A shorter tenure means a smaller loan, even with the same income. Two borrowers means two ages, weighted toward whoever earns more.

How much cash do you need?

Your loan covers part of your purchase price — cash and CPF pay for the rest. The bank lends up to 75%. You pay the other 25% — at least 5% in cash, the rest can be CPF. Buyer's Stamp Duty is due 14 days after exercising your option. This calculator shows the downpayment, minimum cash and stamp duty you'll need on top of the loan. Use those numbers to check the budget matcher for launches that fit, or the progressive payment calculator for when payments are due.

Frequently asked questions

What is TDSR?

The Total Debt Servicing Ratio (TDSR) caps how much debt you can have each month at 55% of your income (before tax and CPF) — mortgage, car loans, credit cards, and any other monthly debt. Banks test this at 4% per annum or higher.

Why does the calculator use 4% instead of my actual rate?

MAS requires banks to stress-test your mortgage at a minimum rate of 4% per annum, even if your actual mortgage rate is lower. Your maximum loan is based on whichever is higher: your actual mortgage rate, or 4%. Choosing a cheaper package doesn't get you a bigger loan.

When does MSR apply?

The Mortgage Servicing Ratio (MSR) limits your mortgage payment to 30% of income. This only applies to HDB flats and new ECs (bought from a developer) — private condos and resale ECs use TDSR instead.

How is bonus or commission income counted?

Banks count only 70% of your variable income (bonus or commission). So a $60,000 annual bonus adds $3,500 a month to your income, not $5,000. This 30% cut applies to your whole income if commission is your only income.

How does age limit my loan tenure?

For the full 75% loan, your tenure is capped at 30 years (25 for HDB) or age 65, whichever is shorter. With two borrowers, the age used is a weighted average based on income — if the older person earns more, that pulls the average up, so your tenure will be shorter. A longer tenure is still possible, but the loan will be capped at 55% loan-to-value instead of 75%.

Can I borrow more by pledging assets?

Yes. Banks can count savings and investments as extra income under MAS rules. To borrow more using savings or investments, use our Pledge and unpledge calculator.

Disclaimer This calculator is an educational estimate, not financial advice and not a loan pre-approval. It applies the TDSR (55%), MSR (30%) and MAS stress-test rules current as of July 2026. These rules can change, and each bank assesses income, bonus cuts, existing debts and tenure a little differently — so what a bank actually offers you may be higher or lower than shown here. Figures assume the inputs you provide are accurate and complete. Always obtain an In-Principle Approval from a bank or licensed mortgage broker, and independent financial advice, before committing to any purchase.

Talk it through with an advisor

A calculator gives you the number; it can't tell you what to do with it. If you want to work through what these figures mean for your own situation — budget, ABSD position, timing an HDB sale, or comparing launches against resale options — you can request a one-to-one consultation.

  • No obligation. The first conversation is about your goals.
  • Affordability and stamp duty worked out on your actual numbers.
  • Launch and tender alerts for the projects you shortlist.
