Property Affordability Calculator Singapore (2026): TDSR, MSR and LTV

Compare the proposed loan with income and valuation limits. This calculator covers ordinary residential purchase scenarios and assumes the remaining lease qualifies for the full applicable LTV. It does not replace a bank assessment or an HDB Flat Eligibility letter.

Calculator

Loan and property route

Recognised gross monthly income (S$)

Use the lender’s assessed income, including its variable-income treatment.

Other assessed monthly debt (S$)

Exclude the proposed loan; include other mortgages and consumer debt.

Of that debt: other housing instalments (S$)

Already included above. Also deducted from the MSR budget; do not enter more than total other debt.

Purchase price (S$)

Property valuation (S$)

For an HDB new flat, use the purchase price.

Planned total downpayment (%)

Cash plus CPF; this input does not prove you have sufficient funds.

Contracted payment-rate assumption (% p.a.)

Used for the actual-payment estimate.

Lender assessment / thereafter rate (% p.a.)

The model enforces at least 4% for bank loans and 3% for HDB loans, and never below the payment rate.

Loan tenure (years)

Whole-month equivalent; HDB and bank limits differ.

Lender assessment age (years)

Use lender-confirmed assessment age for joint applicants.

Other outstanding housing loans

Applicable ABSD rate (%)

Confirm the buyer profile, joint ownership and any remission with IRAS.

How the screen works

Bank loans use TDSR at 55% of recognised gross income, after other assessed debt. HDB-flat bank loans and applicable EC loans also use MSR at 30%. HDB concessionary loans use MSR rather than the bank TDSR framework. Bank assessment uses at least 4%; HDB uses at least 3%. Enter a higher applicable lender rate when required. MoneySense: bank LTV, cash and servicing limits; HDB: September 2022 assessment-rate measures; HDB: housing loan eligibility and limits.

The model then applies the bank LTV table using existing loans, assessment age and tenure, or a 75% HDB ceiling. Lending value is the lower of price and valuation. BSD and the entered ABSD use the higher value. IRAS: stamp-duty rates.

Reproducible borrowing example

With S$12,000 recognised income and S$1,200 other debt, TDSR leaves S$5,400 a month for a mortgage. Change the route to an HDB-flat bank loan: MSR limits it to S$3,600. At 4% over 25 years, the income-based ceiling falls to about S$682,000. A proposed S$900,000 loan therefore exceeds that ceiling, even though it is 75% of a S$1.2 million valuation.

What the cash output does and does not show

The regulatory cash floor is not your total cash requirement. It includes the applicable minimum cash percentage of lending value and any price above valuation. Actual cash can be higher if the loan is smaller, CPF is insufficient or unavailable, or duty must be paid before reimbursement. The upfront total uses your planned downpayment; an unaffordable loan input does not make that funding plan feasible. Use the cash and CPF guide to add fees, renovation, reserves and payment timing.

Cases requiring a separate assessment

The model does not calculate HDB eligibility, grants, short-lease pro-rating, CPF withdrawal limits, credit scoring, joint-borrower assessment age, refinancing exemptions or ABSD remission. HDB tenure may also be limited by remaining lease minus 20 years. Second HDB loans have additional conditions; this model accepts only no outstanding housing loan for that route. Confirm those constraints before relying on the displayed ceilings.

“Within modelled limit” checks only the entered borrowing scenario. Use take-home income for a separate household budget including other debts, property upkeep, dependants and savings. No “safe” financial verdict is inferred from the statutory ratios.

FAQ

Can a low promotional rate increase the modelled loan ceiling?

The model enforces an assessment-rate floor of 4% for bank loans and 3% for HDB loans. A higher lender assessment or thereafter rate should be entered when applicable.

Does the tool apply LTV as well as income ratios?

Yes. It uses the lower of the modelled income ceiling and the valuation-based LTV ceiling.

Does within modelled limit mean approved or affordable?

No. Eligibility, underwriting, CPF, transaction cash and your household budget still need separate checks.
