You want to buy a home but are unsure how your car instalment, other debts and monthly income affect financing readiness. Then someone says, "If your DSR is below this number, the loan will pass."

Treat that claim carefully. DSR helps you understand debt commitments against income, but your own calculation is not a bank approval decision.

What is DSR?

Debt Service Ratio compares monthly debt commitments with monthly income. PIDM explains the basic ratio and notes that banks can have different DSR thresholds.

DSR = monthly debt commitments ÷ income used × 100.

When doing a home-purchase self-check, clearly state whether the proposed home instalment has already been included.

Example before and after adding the home instalment

Assume income used for the exercise is RM5,500, existing monthly debt is RM1,100 and the proposed home instalment is RM1,650.

Before the home instalment: RM1,100 ÷ RM5,500 = 20%.

After adding it: total commitments become RM2,750, so RM2,750 ÷ RM5,500 = 50%.

This is arithmetic only. It does not confirm that a bank will recognise RM5,500 as qualifying income, that the actual instalment will be RM1,650 or that 50% is acceptable.

State what income you are using

PIDM's educational explanation uses net income after statutory deductions. For an actual application, ask the bank what income it recognises, especially for commission, allowances or variable earnings.

Keep basic salary, additional receipts and relevant business flows clearly separated. Money entering an account is not automatically the same as income a lender will use for assessment.

List commitments clearly

Prepare a debt list with the provider, facility type and monthly payment. PIDM's explanation also highlights that debt commitments are not necessarily limited to bank loans.

If you are unsure how a credit card, joint debt or payment plan is treated, make it a question for the bank rather than entering zero.

Never hide debts or inflate unsupported income to improve a ratio.

Prepare evidence, not just a calculator result

Current lender materials include payslips, EPF records, bank statements, commission records and business/tax documents depending on the applicant category. Treat any one bank's list as an example and confirm the actual checklist for your application.

After DSR, make two more checks

First, look at the household budget left for daily life. Second, calculate the cash required during the purchase: price, financing allocation, your own contribution and applicable transaction costs.

"Can I service this every month?" and "Do I have enough money to complete the purchase?" are different questions. For the budgeting side of this exercise, see ASCOLAW's home-buying budget article.

Where do the bank and lawyer have different roles?

Ask the bank about credit assessment, recognised income and financing terms. Ask the transaction lawyer about purchase documents, financing documentation and legal dates.

Once a Letter of Offer is issued, ASCOLAW can walk you through the legal steps that follow.

FAQ

Do all banks use the same DSR limit?

Do not assume so. Ask the bank assessing your application how it treats income and commitments.

Can this article tell me my maximum loan?

No. It helps you organise information and understand the ratio, not produce a credit decision.

I am self-employed. Should I use my highest-income month?

For personal planning, show more than one scenario. For the application, follow the bank's evidence and assessment requirements.
