How much home loan can you borrow?
In Singapore your maximum home loan is the lowest of three limits — MSR, TDSR, and LTV — and the bank stress-tests it at a 4% interest rate, not the rate you're quoted. This free calculator works out all three for an HDB, EC, or private purchase in seconds.
The three limits that cap your loan
MSR (Mortgage Servicing Ratio): for HDB flats and new ECs, your monthly home-loan repayment can't exceed 30% of gross monthly income. It doesn't apply to private property.
TDSR (Total Debt Servicing Ratio): all your monthly debt — the home loan plus car loans, personal loans, and credit-card minimums — can't exceed 55% of gross monthly income.
LTV (Loan-to-Value): a bank first loan is capped at 75% of the lower of price or valuation. It drops to 55% if the tenure runs past 25 years for HDB (30 for private) or beyond age 65.
Your maximum loan is whichever of these caps is lowest — often MSR for HDB buyers, or LTV when the property is expensive relative to income.
Why it's stress-tested at 4%
MAS requires banks to compute MSR and TDSR using a medium-term interest-rate floor of 4% per year, even if your actual package rate is ~3%. This is why your own back-of-envelope sum at the quoted rate usually overstates what you'll be approved for.
Variable income — bonuses, commissions, and rental — is also recognised at only 70% (a 30% haircut) for these checks.
A worked example
On a S$6,000 gross monthly income with no other debts, MSR allows about S$1,800/month toward the loan. At the 4% stress rate over 25 years that supports roughly S$340,000 of HDB loan — regardless of the lower rate you actually pay.
Raise the income, lengthen the tenure (within the age/LTV limits), or lower the price, and the figure moves. The calculator shows the binding limit and the exact maximum for your numbers.
Frequently asked
What's the maximum home loan I can get in Singapore?
It's the lowest of your MSR cap (30% of income, HDB/EC only), TDSR cap (55% of income across all debts), and LTV cap (75% of the lower of price or valuation). Enter your figures to see which one binds and the exact amount.
Does the bank use my actual interest rate?
No. For eligibility, banks must use a 4% medium-term rate floor for MSR and TDSR. Your real (lower) package rate is only used to compute the monthly installment you'll actually pay.
How much can I borrow on a $5,000 salary?
Roughly speaking, MSR allows ~30% (about $1,500/month) toward an HDB loan, which is ~$280,000 at the 4% stress rate over 25 years — before considering TDSR, existing debts, and the property's LTV cap. The calculator gives your precise number.
