TDSR / MSR Scenario Compare

Quick answer: This tool holds your income and debts fixed and compares your loan across four rate environments, showing that your qualifying loan is set by the MAS stress rate while your actual monthly payment changes if rates rise, so you can pressure test whether you could still hold.
Same financial profile, four rate environments. See how much loan you qualify for at each, and what happens if rates spike. The MAS computes affordability at a stress rate, but reality matters too.

Frequently asked questions

Why does my qualifying loan stay the same across all four scenarios?

Because banks size your loan against the MAS stress rate, not today's promotional rate. The tool uses a 4 percent stress rate for private property and 3 percent for HDB and EC, so the qualifying loan is constant. What changes between scenarios is the actual monthly payment you would face if prevailing rates move up or down.

What is the point of modelling rate shock scenarios?

Passing the stress test tells you what you can borrow, but not whether the payments stay comfortable if rates climb. The plus one and plus two percentage point cards show your monthly instalment under higher rates, letting you ask honestly whether you could still service the loan if SORA rose, before you commit rather than after.

How does TDSR differ from MSR in this comparison?

TDSR caps your total monthly debt at 55 percent of gross income and applies to every property type. MSR is a tighter 30 percent cap on housing debt alone and applies only to HDB and EC. For HDB and EC the tool uses the lower of the two limits to set your monthly availability, since the stricter rule binds.

Why is the stress rate lower for HDB than for private property?

The tool applies a 3 percent stress assumption for HDB and EC and 4 percent for private property, reflecting the different medium term rate floors used in assessing these loans. Combined with the 30 percent MSR cap, this shapes how much an HDB or EC buyer qualifies for compared with a private buyer on the same income.

Does a higher monthly payment in the shock scenarios mean I cannot afford the property?

Not necessarily. It shows the payment you would carry if rates rose to that level, so you can judge the cushion in your budget. If the higher figure looks tight against your income and reserves, that is a signal to borrow more conservatively or build a buffer. Winfred Quek can help you set a rate lock and holding strategy.
