TDSR vs MSR in Singapore: What's the Difference?
A practical side-by-side guide to all-debt vs mortgage-only affordability checks.
TDSR is the broader all-debt affordability test, capping total monthly debt at 55% of gross income, while MSR is the mortgage-only test capping the housing instalment at 30% and applying mainly to HDB and EC purchases. You can pass one and still hit limits elsewhere, so it helps to confirm property type, loan route, existing debts, and the lender's own assessment before settling on a realistic price range. Both limits are MAS rules as of 2026 and can change, so verify the current figures with MAS.
TDSR and MSR are related, but they are not interchangeable. The practical distinction is simple: TDSR looks at all your monthly debts and caps them at 55% of gross income, while MSR looks only at the housing instalment and caps it at 30%, mainly for HDB flats and ECs. Both limits are set by MAS as of 2026 and can change, so verify the current figures on MAS before you rely on them. This guide shows where each rule usually applies, what buyers often misunderstand, and how to sanity-check financing before shortlisting homes.
What is the simplest way to explain the difference between TDSR and MSR?
TDSR checks all monthly debt commitments, while MSR checks only the housing loan repayment, usually for HDB and EC cases.
The fastest explanation is this: TDSR looks at all monthly debt commitments and caps them at 55% of gross monthly income, while MSR looks only at the monthly housing loan repayment and caps it at 30%. TDSR is the broader debt screen and MSR is the housing-payment screen.
A simple memory line: TDSR = total debts (55%). MSR = mortgage share (30%).
Why this matters in practice:
- Two buyers can earn the same income, but the one with a car loan or personal instalments usually has less room under TDSR.
- For an HDB or EC buyer, MSR can still limit the housing instalment even if other debts are light.
| Rule | What it measures | Cap (as of 2026) | Where it usually shows up |
|---|---|---|---|
| TDSR | All monthly debt obligations against gross income | 55% | Common in private property financing and any case with existing debt |
| MSR | Monthly mortgage repayment against gross income | 30% | HDB and EC financing (where the minimum occupation period has not expired) |
Start with the property type, then the debt picture. Both the 55% and 30% figures are MAS limits as of 2026 and can change, so verify the current numbers on MAS. For official framing, see MAS's explainer on MSR and TDSR. For a broader overview, see Singapore Property Loan Rules: TDSR, MSR and LTV Explained.
What does TDSR measure, and why does it matter so much for buyers?
TDSR measures your full monthly debt load against gross income and caps it at 55%, so other loans can reduce home loan capacity even when salary looks strong.
TDSR measures how much of your gross monthly income is already spoken for by debt commitments as a whole, not just the new home loan, and it caps that total at 55% as of 2026. That is why it is the key affordability lens when you work out how much you can really borrow.
What buyers often overlook:
- Car loans
- Study loans
- Personal loans
- Credit card instalments
- Existing property loans
A common situation is a buyer with strong income but weaker borrowing power than expected, because existing instalments consume part of the 55% headroom. Two households with similar salaries can therefore get very different loan outcomes.
Note too that banks do not always count your full income. Variable income such as commission, bonus, or allowances, and rental income, is typically discounted by at least 30% under MAS rules (as of 2026), so the figure used in the TDSR test can be lower than your headline pay. Verify the current treatment with MAS or your bank.
A practical point: do not judge affordability on salary alone. Total up your existing debts first, then estimate a budget.

What does MSR measure, and why is it usually linked to HDB financing?
MSR measures only the monthly property loan repayment against gross income and caps it at 30%, which is why it is most relevant to HDB flats and ECs.
MSR looks only at the monthly property loan repayment as a share of gross income, and caps it at 30% as of 2026. It is narrower than TDSR, which is why it is usually the first affordability rule that applies for HDB flats and ECs. MSR applies only to HDB flats and ECs where the minimum occupation period has not expired, not to private property or a resale EC past its MOP. Verify the current rule on MAS.
This is also where buyers get tripped up. You may feel comfortable because overall debts are low, but the housing instalment itself can still be the tighter constraint for the property you want.
How to use it:
- Use MSR to frame the 30% housing-payment ceiling.
- Do not stop there if you are using bank financing, because TDSR (55%) may still apply as well.
- Confirm the loan route before settling on any rough budget.
Memorable line: MSR asks whether the home instalment is too large (30% cap). TDSR asks whether the full debt load is too heavy (55% cap).

Which property types usually involve TDSR, MSR, or both?
Private property cases usually start with TDSR, while HDB and EC cases often involve MSR and may also involve TDSR depending on the loan route.
The practical screening pattern is usually straightforward: private property cases tend to start with TDSR (55%), while HDB and EC cases often bring MSR (30%) into the picture as well.
| Property type | Rule that usually applies first | What to check |
|---|---|---|
| Private property | TDSR (55%) | Full debt commitments, income treatment, and intended loan structure |
| HDB flat | MSR (30%) | Whether you are using a bank or HDB loan, and whether the broader 55% TDSR limit also applies |
| Executive Condominium (EC) | MSR (30%), then TDSR (55%) if bank-financed | Loan route, existing debts, and whether you are a first-timer or upgrader |
The key is not just the property type. The loan route matters too. An HDB or EC buyer using a bank loan can face both checks, so affordability is rarely captured by only one ratio. Both caps are MAS figures as of 2026; verify the current numbers on MAS.

Why do buyers keep mixing up TDSR and MSR?
They sound similar because both are income-based affordability checks and both affect borrowing power, but they are not interchangeable.
The two get mixed up because both are income-based affordability checks, both come up during loan discussions, and both can reduce the final loan amount. To a first-time buyer, they often sound like two versions of the same rule.
The confusion usually gets worse when buyers compare notes with friends who bought different property types. A private condo buyer may talk mainly about TDSR, while an HDB buyer may remember only MSR. The shorthand gets passed around, but the financing context is different.
A simple correction line: MSR is the housing-only cap (30%); TDSR is the all-debt check (55%).
One thing that often trips people up: if the bank told you a housing payment is manageable, that does not automatically mean the rest of your debt picture is clear. For another plain-language reference, see DBS's overview of TDSR. For a broader overview, see How Banks Assess Income for a Home Loan in Singapore.
How do TDSR and MSR affect how much a buyer can borrow?
Both rules cap the monthly instalment a lender is prepared to recognise, and the maximum loan amount is then worked out from that limit.
TDSR and MSR are not just policy terms. They directly shape the monthly instalment a lender is willing to recognise, and the lender then works backwards from that monthly limit (55% for TDSR, 30% for MSR) to estimate the maximum loan amount.
That is why your target budget can change even when income looks healthy on paper. Common scenarios include:
- A salaried buyer with a car loan getting a smaller loan than expected because existing instalments reduce TDSR headroom.
- An upgrader carrying overlapping commitments who looks comfortable on salary, but not once both debt obligations are counted.
- A first-time HDB or EC buyer discovering that the housing instalment itself is the tighter constraint under MSR.
A practical point: work out a shortlist from your likely financing capacity, not from an optimistic top-end number. The 55% and 30% caps are MAS figures as of 2026; verify them on MAS.

What should you check before estimating your financing position?
Check income, debts, property type, and loan route before settling on a budget. That gives a usable first pass without overstating certainty.
- ✓Confirm gross household income and which parts are fixed versus variable (variable income is typically discounted by at least 30% under MAS rules, as of 2026).
- ✓List all existing monthly debt commitments, not just housing loans, since TDSR caps the total at 55%.
- ✓Confirm the target property type: HDB, EC, or private.
- ✓Confirm the intended financing route: bank loan or HDB loan.
- ✓Note whether you are a first-time buyer, upgrader, or may carry overlapping loans.
- ✓Check available cash and CPF for the downpayment and buffers before settling on a price range.
- ✓If income is commission-based or irregular, do not assume the full headline figure will be recognised the same way by every lender.
- ✓Consider an [In-Principle Approval (IPA)](/singapore-property-research/home-loan-ipa-explained) before firm offers or aggressive shortlisting.
What is the biggest mistake when you think you pass one rule?
The biggest mistake is assuming one pass means the whole purchase is cleared. It does not.
Passing one ratio is not the same as being fully cleared to buy. You can pass MSR (30%) but fail TDSR (55%), or meet both and still be limited by LTV rules, CPF usage, property-specific eligibility, or a lender's credit assessment.
Keep this in mind: one pass is a filter, not a full approval. It guards against overconfident shortlists and leaves room to get an IPA before you commit.
How can you sum up TDSR vs MSR without getting technical?
In one line: TDSR checks all monthly debts (capped at 55%), while MSR checks only the housing loan payment (capped at 30%), mainly for HDB and EC purchases.
Here is the plain-English version:
TDSR checks all your monthly debts and caps them at 55% of gross income. MSR checks only the housing loan payment and caps it at 30%, mainly for HDB and EC purchases. If you already have a car loan, personal loan, or other instalments, your borrowing power may be lower than your salary suggests.
Why this framing helps:
- It separates the two rules in one breath.
- It shows why the distinction matters to your budget.
- It points to the next useful step: confirming income, debt, and loan route.
The practical move is to understand the rule once, then focus on a realistic budget you can act on rather than the formulas. The 55% and 30% caps are MAS figures as of 2026; verify them on MAS.
Methodology: where these figures come from and what we did not claim
Where every figure comes from — and what we deliberately did not claim.
Verified figures. Financing figures here come from MAS (TDSR/LTV rules) and CPF — as of 2026; loan rules and rates change, so confirm the current limits with MAS and your bank before you rely on them.
What we have not claimed: the loan amount or approval for any specific borrower (check your bank); a rate quote; or financial advice — a practical explainer only.
