How prepayments pay off your mortgage faster

Every dollar you prepay goes straight against your principal, the amount you actually owe. Because interest is charged on that balance, lowering it early means you're charged less interest for the entire rest of your mortgage. That's why even modest prepayments compound into real savings: a bit extra on each payment, a yearly lump sum when a bonus or tax refund lands, or a one-time lump today can each knock years off your amortization and save tens of thousands in interest.

Most Canadian mortgages come with prepayment privileges, often the ability to pay an extra 10–20% of your balance each year plus raise your regular payment, all without penalty. The trick is knowing your specific limits and putting a plan in place. Once you've seen your numbers, compare payment options with the payment calculator, or see whether a refinance could free up cash to prepay with.

Prepayment FAQs

How do prepayments help me pay off my mortgage faster?
Every prepayment goes straight against your principal, so you owe less and are charged less interest for the rest of the mortgage. Even small extra amounts on each payment, or an annual lump sum, can shave years off your amortization and save tens of thousands in interest.
What is a prepayment privilege?
Most Canadian mortgages let you prepay a set amount each year without penalty, commonly 10% to 20% of the original balance as a lump sum, plus the option to raise your regular payment by a similar percentage. Going over your privilege limit can trigger a charge, so it's worth confirming your specific terms with me.
Is it better to prepay a little each payment or a lump sum once a year?
Both work, and this calculator lets you try either or both. Small amounts on every payment start reducing principal immediately, while a yearly lump sum lets you prepay when you have cash on hand. The best mix depends on your budget and your lender's privileges.
Does prepaying lower my regular payment?
No, prepayments shorten how long you carry the mortgage rather than lowering your set payment. Your regular payment stays the same, you just finish sooner and pay less interest overall.
