Canadian Mortgage Calculator – Estimate Your Monthly Payments

Buying a home is a major financial decision, and knowing your monthly mortgage payments in advance is crucial. A Canadian Mortgage Calculator helps you estimate how much you’ll pay every month based on your loan amount, interest rate, amortization period, and payment frequency.

Why a Mortgage Calculator is Important

• Financial Planning: Helps you budget for monthly payments.
• Interest Understanding: See how interest rates affect your total payments.
• Amortization Awareness: Understand the total cost over the life of the mortgage.
• Comparison: Compare different rates and terms to choose the best mortgage option.

Key Mortgage Parameters

• Loan Amount (P): The total amount you are borrowing from the bank.
• Annual Interest Rate (r): The mortgage rate per year (in %).
• Amortization Period (n): The total number of years you plan to repay the mortgage.
• Payment Frequency: Monthly, bi-weekly, or weekly payments.

Mortgage Payment Formula

The standard formula to calculate the monthly mortgage payment is:

M = P × [r(1 + r)ⁿ] / [(1 + r)ⁿ – 1]

• M – Monthly mortgage payment
• P – Principal loan amount
• r – Monthly interest rate (annual rate ÷ 12 ÷ 100)
• n – Total number of monthly payments (years × 12)

Step-by-Step Example

Problem: You borrow $350,000 at an annual interest rate of 5% for 25 years. Calculate the monthly payment.
Step 1: Convert annual rate to monthly: r = 5 / 12 / 100 = 0.0041667
Step 2: Calculate total payments: n = 25 × 12 = 300 months
Step 3: Apply the formula:
M = 350,000 × [0.0041667 × (1 + 0.0041667)³⁰⁰] / [(1 + 0.0041667)³⁰⁰ – 1]
Step 4: Calculate powers and division: M ≈ $2,046.25 per month
