Singapore Loan Affordability Calculator SGD

By Chuck, Finance Atlas — Updated October 2026

Work backwards from your gross monthly income, existing obligations and a debt-service ceiling you set to the unsecured loan amount that payment could support — in Singapore dollars (SGD), with the TDSR and MSR as context.

S$

Your regular monthly income before deductions. Use the figure a lender would document — payslips or notices of assessment.

S$

Total monthly repayments you already make — other loans, car instalments, card minimums. These reduce capacity first.

%

8.00% is an illustrative example only — NOT a current Singapore market rate. Enter the rate your bank or lender quotes.

Longer terms support larger loans at the same payment — and cost far more interest.

How Much Can You Safely Borrow in Singapore?

This calculator works backwards. You set a debt-service ceiling — a share of your gross monthly income you are willing to commit to debt — and the calculator subtracts what you already pay, works out the maximum monthly instalment left, then converts that payment stream into the loan principal it supports at the rate and term you entered. It is the same present-value mathematics every lender uses; the only judgement call is the ceiling, which is deliberately yours to set rather than ours to assume.

A conservative starting point is 30–35% of gross monthly income going to all debt obligations combined. Singapore's own regulatory ceilings give useful reference points: the MAS Total Debt Servicing Ratio caps property loans at 55% of gross monthly income across every obligation you hold, and the 30% Mortgage Servicing Ratio applies to housing loans for HDB flats and executive condominiums specifically. Unsecured credit has no single published DSR. The 12-times-monthly-income threshold is particularly relevant to Singapore's Debt Consolidation Plan framework and certain unsecured-credit situations — not a universal personal-loan approval limit — and individual banks apply their own affordability and credit screens on top of any regulatory context.

Why the rate matters so much here

The affordable loan is extremely sensitive to the rate because the payment is fixed by your ceiling. With the example inputs — S$5,000 gross monthly income, S$500 existing obligations, a 35% ceiling and a 3-year term — the affordable payment is S$1,250 a month. At the illustrative 8.00% rate that supports about S$39,900 of borrowing; at 12% it falls to roughly S$37,600; at 4% it rises to about S$42,300. Same discipline, very different purchasing power — which is why shopping the rate before shopping the loan matters, and why this calculator never assumes one.

What this is not

It is not a pre-approval and not a promise. Lenders document income differently (they may average variable components, or discount bonuses), apply their own stress tests, and check credit bureau records — your actual approval may come in above or below the figure shown. Treat the output as a sanity ceiling: if the loan you are considering is comfortably inside it, the conversation with the lender is worth having; if it is outside it, the maths is telling you something. For housing specifically, switch to the Singapore Home Affordability Calculator, which adds down payment, purchase costs and the MSR/TDSR context.

Frequently Asked Questions

What debt-service ceiling should I set?

There is no official number for unsecured borrowing. A common personal-finance guideline is keeping all debt repayments at or below 30–35% of gross monthly income. Singapore's regulatory anchors: the TDSR caps property loans at 55% of gross monthly income, and the MSR caps HDB/EC housing loans at 30%. Set the ceiling you could live with, not the maximum a rule allows.

Does the calculator know about the 12-times-income limit?

No — this page computes what a repayment ceiling supports. The 12-times-monthly-income threshold is particularly relevant to Singapore's Debt Consolidation Plan framework and certain unsecured-credit situations; it is not a universal personal-loan approval limit, and individual financial institutions apply their own regulatory, affordability and credit assessments.

Should I include my mortgage in existing obligations?

Yes — every monthly repayment you already make, including housing loans, car loans and card minimums, should go in the existing-obligations field. The ceiling applies to total debt service, not just the new loan.

Why is the affordable loan smaller than I expected?

Usually one of three inputs: the rate is higher than you assumed, the term is shorter, or existing obligations are eating the capacity. Longer terms raise the affordable principal — and the total interest; check both on the Singapore Loan Repayment Calculator before committing.

Is my income information sent anywhere?

No. Everything runs locally in your browser. Nothing you type is transmitted, stored or logged.
