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 (home price - down payment) i = monthly interest rate (annual rate / 12) n = number of payments (amortization period in years × 12)

This formula calculates the fixed monthly payment required to fully amortize the loan over the selected term.

Worked Example

Let's calculate a mortgage for a $500,000 home with a 20% down payment, 5.25% interest rate, and 25-year amortization:

Down payment: $500,000 × 20% = $100,000
Principal: $500,000 - $100,000 = $400,000
Monthly rate: 5.25% ÷ 12 = 0.4375% or 0.004375
Number of payments: 25 × 12 = 300
Using the formula:
M = $400,000 [ 0.004375(1 + 0.004375)^300 ] / [ (1 + 0.004375)^300 - 1 ] M ≈ $2,950.48

Your estimated monthly payment would be approximately $2,950.48.

Understanding Amortization

Amortization is the process of paying off your mortgage loan in regular installments over time. The longer your amortization period, the lower your monthly payment will be, but you'll pay more in total interest over the life of the loan.

Common amortization periods in Ontario include:

5 years (most common for investors)
10 years (popular for first-time buyers)
15 years (good balance of payments and interest)
25 years (traditional term for homeowners)

The amortization schedule shows how much of each payment goes toward interest and principal over time. Early payments primarily cover interest, while later payments focus more on principal repayment.

Frequently Asked Questions

What is the difference between fixed and variable rates?

Fixed rates stay the same throughout the loan term, while variable rates can change based on market conditions. Fixed rates typically have higher upfront costs but provide stability, while variable rates may offer lower initial payments but can fluctuate.

How much should I put down as a down payment?

In Ontario, the minimum down payment is typically 5% for conventional mortgages. A larger down payment (10-20%) can reduce your monthly payments and interest costs while improving your mortgage approval chances.

What are closing costs?

Closing costs are additional fees beyond the mortgage amount that cover appraisal, legal fees, land transfer taxes, and other expenses. These typically range from 2-5% of the home price.

Can I pay off my mortgage early?

Yes, you can pay off your mortgage early without penalty. This can save you money on interest and help you build equity faster. Some lenders may offer prepayment privileges that allow you to withdraw funds from your mortgage without penalty.

What happens if I can't make my mortgage payments?

If you're unable to make payments, contact your lender immediately. They may offer solutions like payment deferrals, loan modifications, or forbearance agreements. Missing payments can lead to late fees, negative equity, and potential foreclosure.
