1. What is the Mortgage Rate Change Calculator?

The Mortgage Rate Change Calculator helps UK homeowners estimate how their monthly mortgage payments will change when interest rates increase or decrease. It provides a quick calculation based on the proportional relationship between old and new interest rates.

2. How Does the Calculator Work?

The calculator uses the mortgage payment change formula:

\[ \text{New Payment} = \text{Old Payment} \times \left( \frac{\text{New Rate}}{\text{Old Rate}} \right) \]
