1. What is an Ontario Mortgage Calculator?

Definition: This calculator estimates monthly mortgage payments for Ontario, Canada, including the effective interest rate calculation and average property tax.

Purpose: It helps homebuyers in Ontario understand their potential mortgage payments with the unique Ontario interest calculation method.

2. How Does the Calculator Work?

The calculator uses two formulas:

Where:

• \( n \) — Number of payments (months)
• \( i \) — Annual interest rate (decimal)
