What can you actually afford?

Your maximum loan and property price the way a bank computes it: TDSR 55%, MSR 30% where it applies, the 4% stress test, the 30% haircut on variable income, and the income-weighted age cap on tenure. Then the number most calculators skip — the upfront cash and CPF that maximum price implies.

How the limit is found

Assessable income = fixed salary + 70% of bonus ÷ 12. The bank takes the stricter of TDSR (55% of income minus existing debts) and, for HDB/new EC, MSR (30% of income). That monthly ceiling, discounted at the stress rate over your capped tenure, is your maximum loan. Price = loan ÷ 75% LTV. Tenure is capped at 30 years for private/EC (25 for HDB) and by income-weighted average age to 65 for the full LTV.

The four rules that set your ceiling

TDSR 55% is the universal cap: every monthly debt you carry, including the new mortgage, may not exceed 55% of gross income. MSR 30% stacks on top for HDB flats and developer-sold ECs, capping the mortgage alone — for most HDB and new EC buyers, MSR binds first. The 4% stress floor means the bank sizes your loan at 4% per annum even if your package is cheaper, so a falling rate environment does not raise your maximum loan. And the tenure cap — 30 years for private (25 for HDB), ending by age 65 for full LTV, computed on income-weighted average age for joint borrowers — quietly matters most: the same monthly ceiling supports a much smaller loan over 18 years than over 30.

The number after the number

A maximum price is only half the answer. At 75% LTV, that price implies a 25% downpayment — at least 5% in cash, the rest in cash or CPF — plus Buyer's Stamp Duty within 14 days of exercising the option. This calculator shows that total upfront requirement alongside the loan, because plenty of buyers can service the maximum loan but cannot fund the maximum price. When you have your figure, hand it to the budget matcher to see which active launches fit it, or to the progressive payment calculator to see when the money actually leaves your accounts.

Frequently asked questions

What is TDSR?

The Total Debt Servicing Ratio caps all monthly debt obligations — the new mortgage plus car loans, credit cards and other debts — at 55% of gross monthly income, assessed at a medium-term interest rate floor of 4% per annum for residential loans.

When does MSR apply?

The Mortgage Servicing Ratio caps the housing loan instalment alone at 30% of gross income, and applies only to HDB flats and executive condominiums bought directly from a developer. Private condos and privatised ECs face TDSR only.

How is bonus or commission income counted?

Variable income takes a minimum 30% haircut — only 70% counts. A S$60,000 annual bonus adds S$3,500 a month to assessable income, not S$5,000. Fully commission-based earners should expect banks to apply the haircut to their entire income.

How does age limit my tenure?

For the full 75% LTV, the loan must end by age 65 and cannot exceed 30 years (25 for HDB). Joint borrowers are assessed on income-weighted average age — a higher-earning older borrower pulls the cap down more. Longer tenures are possible but drop the LTV to 55%.

Can I borrow more by pledging assets?

Yes — banks can recognise pledged or unpledged financial assets as income streams under MAS rules, which raises assessable income. That is outside this calculator's scope; treat its result as the plain-income baseline.

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.
