Does this include MSR?

This calculator uses a TDSR-style cap as the primary borrowing gate. MSR can apply for HDB/EC scenarios and may be tighter. Use the TDSR/MSR guide for the full framework.

What’s a safe monthly mortgage ratio?

A practical stress-tested band is to keep mortgage instalment at about 20–30% of gross income for comfort, 30–35% as a stretch zone, and above 35% as high-stress—especially with dependents or large fixed commitments.

Q: How accurate is this property affordability calculator?

This is a simplified stress-test model. Banks may haircut variable income, include all debts, apply stress rates, and apply MSR for certain purchases. Use this to avoid instalment-only thinking, then validate with actual bank/agent figures.

Not financial advice. This is a simplified stress-test model (not a bank approval). Banks can haircut variable income, include all debts, apply stress rates, and apply MSR for certain purchases. If you want the framework behind the logic: TDSR & MSR explained.

Inputs

Gross monthly income (SGD)

Use gross, not take-home (banks assess with gross).

Existing monthly debt commitments (SGD)

Car loans, credit cards, student loans, other mortgages.

Interest rate assumption (% p.a.)

Stress-test +0.5% to see fragility.

Loan tenure (years)

Property price (SGD)

Downpayment (%)

This is total downpayment (cash + CPF combined).

Model assumptions (simple v1)

TDSR cap assumption: 55% of gross income for total debt repayments.
MSR is not applied here and may be tighter for HDB/EC cases.
BSD is a rough estimate using tiered rates. Validate with IRAS schedule.

Outputs

Status

—

Estimated monthly instalment (for your chosen price)

—

Max loan allowed (TDSR-style cap)

—

Max property price (given your downpayment %)

—

Upfront exposure estimate (downpayment + rough BSD)

—

Upfront exposure ignores renovation and buffers — see cash required.

Interpretation

If your instalment is close to the cap, your plan is fragile. Property is a multi-year capital structure decision. Don’t ignore interest drag, setup shock, and exit friction.

FAQ

Does this replace a bank approval?

No. Treat it as a planning tool. Banks may haircut income, include all debts, and use stress rates that differ from your assumptions.

Why is my max loan lower than expected?

TDSR includes existing debts and banks apply stress rates. Read: TDSR & MSR guide.
