TDSR MSR SingaporeTotal Debt Servicing RatioMortgage Servicing Ratio
You can love a unit and still
not be allowed to borrow enough for it. Two MAS rules — the Total Debt
Servicing Ratio (TDSR) and the Mortgage Servicing Ratio (MSR) — quietly set the
ceiling on your loan before you've even made an offer. Here's how they work and
which one bites.
●
TDSR — 55%. Your total monthly debt repayments
(home loan, car loan, personal and student loans, credit card minimums, and so
on) cannot exceed 55% of your gross monthly income. It applies to all
property loans.
●
MSR — 30%. Your monthly home-loan repayment
alone cannot exceed 30% of your gross monthly income. MSR applies only
to HDB flats and Executive Condominiums (ECs).
●
HDB flat with an HDB (concessionary) loan: only
MSR applies.
●
HDB flat with a bank loan: both apply — and MSR
(the 30% cap) is usually the tighter, binding constraint.
●
Executive Condominium from a developer: both
apply during the MOP.
●
Private condo / landed: only TDSR applies.
Where both apply, the lower of
the two allowances is the one that limits your loan.
The stress-test rate.
Banks don't size your loan at today's interest rate. They apply a medium-term
floor of 4% for residential property loans (or the prevailing rate,
whichever is higher). So even if your actual rate is lower, your maximum loan
is calculated as though you were paying around 4% — which meaningfully reduces
how much you qualify for.
The variable-income haircut.
If part of your income is variable — commissions, bonuses, allowances — only
about 70% of it counts (a haircut of at least 30%). Self-employed and
commission-based buyers should plan around this.
Separately from the servicing
ratios, LTV caps how much of the price you can borrow. For an HDB housing
loan, the LTV limit is 75% (reduced from 80% on 20 August 2024). A first
bank loan is also capped at up to 75% LTV for a loan within standard tenure
limits. The rest comes from CPF and cash — so your down payment, not just your
monthly budget, needs planning.
Take your gross monthly income,
apply the binding cap (55% TDSR, or 30% MSR for HDB/EC), subtract your existing
monthly debt commitments, and that leftover is what's available to service a
mortgage — sized at the 4% stress rate. Two buyers with identical incomes can
qualify for very different loans purely because one carries a car loan and the
other doesn't.
●
Clear or reduce high monthly commitments (car loans
especially) before your loan assessment — they eat directly into your TDSR
headroom.
●
Avoid taking on new unsecured borrowing in the months
before you buy.
●
If you're buying HDB, remember your HFE letter already
gives you HDB's own loan eligibility figure — a useful anchor. See the HFE
guide in this cluster.
Is the TDSR limit still 55%?
Yes. It was reduced from 60% to
55% in December 2021 and remains 55% in 2026. Any article still quoting 60% is
out of date.
Does TDSR apply to an HDB loan?
No — an HDB concessionary loan
is assessed on MSR (30%) only. TDSR applies when you take a bank loan.
Why is my approved loan lower than I expected?
Usually the stress-test rate
(around 4%) and, if relevant, the 30% haircut on variable income. Both are
designed to make sure you can service the loan if rates rise.
What counts as debt for TDSR?
Property loan repayments, car
loans, personal and student loans, renovation loans, and credit card repayments
— essentially your recurring monthly obligations.
Not sure what you can really
borrow? I work with mortgage partners to pressure-test your TDSR/MSR and down
payment before you fall for a unit you can't finance. [Book a consultation.]
