Formula Used

The calculator uses the standard mortgage payment formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ] Where: M = Monthly payment P = Principal loan amount i = Monthly interest rate (annual rate / 12 / 100) n = Number of payments (amortization period in years × 12)

Total interest paid is calculated as:

Total Interest = (Monthly Payment × Number of Payments) - Principal Loan Amount

Worked Example

Let's calculate a mortgage with these parameters:

Loan amount: $300,000
Annual interest rate: 5.25%
Amortization period: 25 years

Using the formula:

Monthly interest rate = 5.25% / 12 / 100 = 0.004375 Number of payments = 25 × 12 = 300 Monthly payment = $300,000 [ 0.004375(1 + 0.004375)^300 ] / [ (1 + 0.004375)^300 - 1 ] Monthly payment ≈ $1,724.68 Total interest paid = ($1,724.68 × 300) - $300,000 = $157,404.40

So for this example, your monthly payment would be approximately $1,724.68, and you would pay $157,404.40 in total interest over 25 years.

Frequently Asked Questions

What is the difference between fixed and variable mortgage rates in Ontario?

A fixed-rate mortgage has an interest rate that remains the same for the entire term of the loan, providing predictable payments. A variable-rate mortgage (also called an adjustable-rate mortgage) has an interest rate that can change over time, typically tied to a benchmark rate like the Bank of Canada's rate.

How does the amortization period affect my mortgage payments?

A longer amortization period means lower monthly payments but more total interest paid over the life of the loan. A shorter amortization period results in higher monthly payments but less total interest paid. Choose a term that fits your financial situation and goals.

What is the difference between principal and interest payments?

Principal payments reduce the amount you owe on the loan, while interest payments cover the cost of borrowing the money. In the early years of a mortgage, most of your payment goes toward interest. Over time, as the principal balance decreases, more of your payment goes toward principal.
