Property Affordability Calculator (TDSR & MSR)

Before you start viewing, find the ceiling — the maximum home loan and property price your income supports under MAS rules. Worked out at the 4% stress-test rate, so it reflects what a bank would actually assess.

Note: These figures are illustrative and opinion-based, produced with calculation tools — not a valuation or financial advice. Human error is possible; verify against a licensed bank or mortgage broker before relying on them.

Property type

HDB and ECs are also checked against the 30% MSR cap, whichever is lower.

Fixed monthly income

Your basic salary, before tax and CPF. Recognised in full.

Variable monthly income (optional)

Commissions, bonuses and allowances, as a monthly average (e.g. annual bonus ÷ 12). Banks recognise 70% of this.

Existing monthly debt repayments

Car loans, personal loans, credit-card minimums, other property loans. Leave blank if none.

Loan tenure

Max 35 years for private property (30 for HDB/EC). Longer tenures past age 65 reduce your loan limit.

Estimate only. Computed at the MAS 4% stress-test rate, with a 30% haircut applied to variable income, and assuming a 75% loan-to-value first housing loan. Your actual loan depends on the bank's assessment of income, age, credit and tenure. Not financial advice.


How affordability is worked out

The MAS rules this calculator applies, and what each one limits
TDSRAll monthly debts, including the new mortgage, must stay within 55% of gross monthly income. Applies to every property loan.
MSRThe mortgage alone must stay within 30% of gross income. Applies only to HDB flats and ECs — the lower of TDSR and MSR is binding.
Stress rateThe maximum loan is sized at a 4% medium-term interest rate floor, not your actual rate, so you can still service it if rates rise.
TenureUp to 35 years (private) or 30 years (HDB/EC). Tenures past age 65 or beyond the cap reduce the loan-to-value limit.
LTVA first housing loan is capped at 75% of price or value. The price shown assumes you fund the remaining 25% in cash and CPF.

Source: MAS — TDSR for property loans. Rates and rules as of July 2026; variable income is subject to a 30% haircut. Verify current figures with MAS or your bank before relying on them.


Questions

What's the difference between TDSR and MSR?

TDSR caps all your monthly debt repayments — including the new mortgage — at 55% of gross monthly income, and applies to every property loan. MSR caps just the mortgage at 30% of gross income, and applies only to HDB flats and ECs bought from a developer. For HDB and EC, both are checked and the lower allowance is binding.

Why does this use 4% and not my actual interest rate?

MAS requires banks to stress-test affordability using a medium-term interest rate floor — currently 4% per annum for residential property, or your actual rate if higher. So even if your real mortgage rate is lower, the maximum loan is worked out at 4% to make sure you can still service it if rates rise.

Is this the amount a bank will definitely lend me?

No — it's an estimate. Your actual loan depends on the bank's assessment of your income (variable income takes a 30% haircut), age, credit record, loan tenure, and LTV limits. Treat this as a planning figure and confirm with a banker or mortgage broker.

I believe real estate should be strategic, seamless, and deeply aligned with your life’s journey.
