Can a home loan affordability calculator consider fluctuating interest rates?

Home loan affordability calculators work based on the interest rate you input and might now factor in potential future rate fluctuations. They provide an affordability estimate using fixed-rate assumptions.

However, affordability calculators do allow you to model different interest rate scenarios. These calculators let you input different interest rates to see how changes may impact on your monthly mortgage payment and overall affordability amount.

For example, you could test affordability at the current rate, a 2% higher rate, and a 3% higher rate to understand how rate hikes could affect your budget. This allows you to make an informed decision on the maximum monthly payment you'd be comfortable with even if rates rose.

It's wise to consider affordability using both today's rates and potentially higher rates.
