Using our Ontario mortgage calculator is simple:

Click Calculate to see your monthly payment and other details

The calculator will show you your estimated monthly payment, total interest paid over the life of the loan, and a breakdown of how much principal and interest you'll pay each month.

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 divided by 12)
n = Number of payments (amortization period in years × 12)

This formula calculates the fixed monthly payment required to fully amortize a loan with compound interest.

Worked Example

Let's calculate a mortgage payment for a $300,000 loan at 5% annual interest over 25 years:

Principal (P) = $300,000
Annual interest rate = 5% (0.05)
Monthly interest rate (i) = 0.05 / 12 ≈ 0.004167
Number of payments (n) = 25 × 12 = 300

Plugging these into the formula:

M = 300,000 [ 0.004167(1 + 0.004167)³⁰⁰ ] / [ (1 + 0.004167)³⁰⁰ - 1 ]

M ≈ $1,875.80 per month

This means you would pay approximately $1,875.80 each month for 25 years to repay the $300,000 loan.

Frequently Asked Questions

What is the difference between fixed and variable mortgage rates?

A fixed-rate mortgage has the same interest rate for the entire term of the loan, while a variable-rate mortgage's interest rate can change based on market conditions. Fixed rates typically offer more stability, while variable rates may offer lower initial rates.

How does the amortization period affect my mortgage payments?

A longer amortization period (typically 25 or 30 years) results in lower monthly payments but means you'll pay more in total interest over the life of the loan. A shorter period (like 10 or 15 years) means higher monthly payments but less total interest paid.

What is the difference between principal and interest payments?

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

How can I lower my mortgage payments?

You can lower your mortgage payments by making larger down payments, choosing a longer amortization period, or negotiating a lower interest rate with your lender. You can also consider refinancing if interest rates have decreased since you originally took out your mortgage.
