About this tool

The Mortgage Calculator figures out your monthly payment, total interest paid over the life of the loan, and a full amortization table showing how each payment splits between principal and interest. It works for standard fixed-rate mortgages and is useful for first-time buyers, homeowners considering refinancing, or anyone comparing loan scenarios before talking to a lender.

Reach for this tool when you want a clear picture of what a home loan actually costs over time, not just the monthly number. It is especially handy when you are stress-testing different down payments, interest rates, or amortization periods side by side before committing to anything.

How to use it

  1. Enter the home purchase price or the total loan amount you need to borrow.
  2. Input your down payment as a dollar amount or percentage of the purchase price.
  3. Enter the annual interest rate quoted by your lender or from a rate comparison site.
  4. Select your amortization period, typically 25 years in Canada, or adjust to compare options.
  5. Choose your payment frequency: monthly, bi-weekly, or accelerated bi-weekly.
  6. Click Calculate to see your payment amount, total interest, and the full amortization schedule.

Pro tips

  • Switch to accelerated bi-weekly payments to shave years off your mortgage and save thousands in interest without feeling a big budget difference.
  • Run the calculator twice using rates 1 to 2 percent higher than today to stress-test affordability before rates renew.

FAQ

Does this calculator handle Canadian mortgage rules like semi-annual compounding?
Yes, the calculator uses semi-annual compounding as required for Canadian fixed-rate mortgages, so the numbers align with what a Canadian lender would quote you.
Can I use this to calculate a refinance?
Absolutely. Just enter your remaining balance as the loan amount, your new rate, and the years left you want to carry it, and the tool will show the new payment and total cost.
