Estimates only. This is a simplified TDSR-based affordability cap assuming a 30-year tenure and no Additional Buyer's Stamp Duty (ABSD), which depends on your residency and properties owned. Actual loan eligibility, LTV and duties depend on the bank's assessment and your full circumstances — always confirm with a banker or IRAS.
How condo affordability is calculated
Private-property affordability hinges on three MAS rules. First, the Total Debt Servicing Ratio (TDSR) caps all your monthly debt — including the new mortgage — at 55% of gross monthly income. Subtracting any existing debt gives the most you can put toward a home loan each month.
Second, that monthly figure is converted into a maximum loan as the present value of the payments at the 4% medium-term stress rate over a 30-year tenure. Third, the 75% loan-to-value (LTV) limit means the loan can cover at most 75% of the price, so the affordable price is the loan divided by 0.75 plus the cash and CPF you bring to the table.
Don't forget stamp duty and other costs
On top of the downpayment you pay Buyer's Stamp Duty (estimated here from the progressive BSD tiers), and possibly Additional Buyer's Stamp Duty depending on your residency and properties owned. Budget for legal fees, valuation and a buffer for monthly outgoings beyond the mortgage. Compare scenarios with our mortgage, ABSD and TDSR calculators before committing.
Frequently asked questions
How much condo can I afford in Singapore?
For private property, the binding limit is usually the Total Debt Servicing Ratio (TDSR): your total monthly debt repayments — including the new mortgage — cannot exceed 55% of your gross monthly income. This calculator turns that allowance into a maximum loan at the 4% stress-test rate over 30 years, adds your cash and CPF, and works back to the highest price you could afford.
Why is a 4% interest rate used instead of the actual rate?
MAS requires banks to size the loan using a medium-term interest-rate floor — currently 4% for residential property — even if the rate you actually pay is lower. This stress test ensures you can still service the loan if rates rise, so the calculator uses 4% to compute the maximum loan.
How much downpayment do I need for a condo?
For a first housing loan the bank can lend up to 75% of the price (Loan-to-Value limit), so you fund at least 25% — of which at least 5% must be in cash and the rest can be CPF. You also need cash or CPF for Buyer’s Stamp Duty and legal fees. Enter your combined cash and CPF to see how it lifts your affordable price.
Does this include ABSD?
No. This estimate covers Buyer’s Stamp Duty (BSD) only. Additional Buyer’s Stamp Duty (ABSD) depends on your residency status and how many residential properties you already own — a Singapore Citizen pays 0% on a first home but 20% on a second. Use the ABSD calculator to layer that on top.
