Extra Mortgage Payments Calculator (Canada)

How extra mortgage payments reduce interest in Canada

Making extra mortgage payments is one of the most effective ways to reduce interest and pay off your home faster. In Canada, even small additional amounts added to each payment can significantly shorten your amortization period. This calculator shows how extra payments and lump sums affect your payoff time and total interest paid.

When you add extra payments, the additional money goes directly toward your principal balance. Because interest is calculated on the remaining balance, reducing principal earlier lowers interest for every future payment. Over long amortization periods, this compounding effect can lead to substantial savings.

Canadian mortgages often allow limited prepayments without penalties, such as increasing regular payments or making annual lump sums. However, prepayment limits vary by lender and mortgage type. Always check your mortgage terms before committing to large extra payments.

This calculator compares your original mortgage schedule with a scenario that includes extra payments and optional lump sums. It estimates how many years sooner you could be mortgage-free and how much interest you could save over the life of the loan.
