Frequently asked questions
How does this affordability calculator work out my maximum loan?
It takes your gross monthly income, caps total debt servicing at 55 percent under TDSR, deducts your existing debts, then works backwards from that monthly ceiling using the MAS 4 percent stress rate and your loan tenure to find the largest loan that fits. For HDB or EC it also applies the 30 percent MSR limit.
Why does the tool use a 4 percent rate instead of my actual mortgage rate?
MAS requires every Singapore bank to underwrite home loans against a medium term stress rate, with 4 percent as the floor, even when your promotional rate is lower. The calculator mirrors this because that is the figure the bank assesses you against, so your real approved amount tracks the stress test, not the headline rate.
Is the maximum purchase price the same as my budget?
No. The result is your legal ceiling, not a comfortable budget. Winfred Quek treats it as an upper bound only. Your workable budget should also absorb stamp duty, CPF drawn down, legal fees, renovation and several months of reserves, which usually puts a sensible target well below the calculated maximum.
How do my existing car loan and credit card debts affect the result?
Every monthly obligation reduces your TDSR room dollar for dollar. Since TDSR caps total monthly debt at 55 percent of gross income, a car loan, personal loan, student loan or credit card minimum directly shrinks the room left for a new mortgage instalment, which in turn lowers your maximum loan and purchase price.
What LTV should I enter for my first property?
For a first private housing loan with no other outstanding home loans, the LTV limit is typically 75 percent, which the tool uses by default. Second and subsequent loans face tighter LTV limits, so you would lower this figure. The loan amount also still has to clear the TDSR or MSR check, whichever binds first.
