1. What is Mortgage Interest Calculation?

The mortgage interest calculation determines the monthly interest payment on a mortgage loan in Canada. It helps homeowners understand how much of their monthly payment goes toward interest versus principal reduction.

The calculator uses the mortgage interest formula:

Where:

• \( I \) — Monthly interest payment (currency units)
• \( P \) — Principal amount (currency units)
