Short answer
DSR means Debt Service Ratio. It compares monthly debt commitments with monthly income. Banks use affordability assessments when considering whether a proposed housing instalment fits alongside your existing obligations.
The simple formula is:
- DSR = total monthly commitments divided by recognised monthly income x 100.
If your recognised income is RM8,000 and the bank counts RM4,800 total commitments after adding the new mortgage, your DSR is 60%.
The important word is recognised
Many buyers think DSR must use the salary written in an offer letter. In practice, the bank first decides which documented income it recognises under its policy. PIDM's consumer guide demonstrates DSR using net income, while an individual bank's application may ask for several forms of evidence.
For a salaried employee, recognised income may include:
- Basic salary.
- Fixed allowance.
- Variable allowance if consistent.
- Overtime if repeated and supported.
- Commission or incentive after averaging.
- Bonus, sometimes averaged or treated separately.
For self-employed applicants, recognised income can be more complicated. A current Maybank mortgage checklist, for example, asks business owners for tax filing evidence and six consecutive months of business current-account statements. Another bank may request or interpret evidence differently.
What goes into total monthly commitments
Commitments usually include existing debt plus the new loan being applied for.
Common items are:
- Car loan.
- Personal loan.
- Existing housing loan.
- Credit card commitment.
- Education financing if counted.
- Overdraft, business loan or company facilities if personally guaranteed.
- The estimated instalment for the new housing loan.
This is why a buyer with RM10,000 income can still fail if existing commitments are heavy, while a buyer with RM7,000 income can pass if the profile is clean and the property price is reasonable.
A simple DSR example
Assume RM8,000 of monthly income is recognised for an illustration.
Existing commitments:
- Car loan: RM900.
- Personal loan: RM600.
- Credit card commitment: RM300.
- New housing loan instalment: RM2,700.
Total commitments are RM4,500. The DSR is RM4,500 divided by RM8,000, which is 56.25%.
A 56.25% DSR is the arithmetic result, not an approval verdict. The bank still decides which income and obligations to use, its acceptable limit for the application and whether other credit criteria are met.
Why every bank does not give the same answer
There is no single percentage you should assume every Malaysian bank will apply to every borrower. Even PIDM notes that each bank may have its own threshold. Treat public rules of thumb as education, not as a bank quotation.
Two banks can look at the same borrower and differ on:
- Whether they use gross income, net income or adjusted income.
- How they average commission.
- How much they count from credit card outstanding.
- Whether they accept rental income.
- Whether they count a joint loan fully or partially.
- What stress rate they use for the new mortgage instalment.
So if someone says "banks allow 70% DSR", treat that as a rough guide, not a promise.
Credit cards can quietly push DSR up
Credit card outstanding is one of the easiest ways to spoil an otherwise strong file. Even if you pay on time, a high outstanding balance can be converted into a monthly commitment for DSR.
The method used to convert card exposure into a monthly commitment can vary. Instead of relying on a universal percentage, check the assumption used in your estimate and confirm the bank's treatment for an actual application.
Before applying, check your CCRIS record and current card outstanding. You can access CCRIS through Bank Negara Malaysia's eCCRIS portal.
DSR is not the only approval gate
Passing DSR does not automatically mean approval. Banks still check:
- Repayment conduct in CCRIS.
- CTOS and other credit information.
- Job and income stability.
- Employer or business profile.
- Property valuation and property risk.
- Margin of finance.
- Cash available for down payment and costs.
- Consistency between documents.
This is why mortgage approval can be rejected even when the DSR percentage looks fine.
How to prepare before applying
Before you submit to a bank, prepare the numbers in this order:
- Confirm recognised income from documents.
- List every monthly commitment.
- Check credit card outstanding.
- Estimate the new housing loan instalment.
- Calculate DSR under a conservative assumption.
- Compare a few banks if the file is near the edge.
You can use the housing loan eligibility calculator for the first estimate, then check the result against your real payslips, statements and CCRIS record. For the wider approval picture, read why a mortgage can be rejected despite a good salary.

Bottom line
DSR is simple on paper, but bank treatment is not always simple. The cleanest application is one where income is easy to prove, commitments are low, cards are controlled and the requested loan leaves breathing room.
