Prepayment Privileges: How Much You Can Put Toward Your Mortgage Without a Penalty

What a Prepayment Privilege Actually Covers

Every closed mortgage in Canada comes with two numbers that matter more than most people realize until they need them: the regular payment you're committed to, and the extra amount you're allowed to put down on top of it without a penalty.

According to the Financial Consumer Agency of Canada's page on paying off a mortgage faster, that extra allowance generally comes in a few forms: a lump-sum payment made at certain points during the term, an increase to your ongoing payment amount, or both together, depending on what your specific contract permits. “You may only be able to increase your payments by a certain amount each year,” the FCAC notes, and once you increase them, “you can't lower them until the end of the term.”

Some lenders also offer accelerated payment frequencies — accelerated weekly or biweekly, rather than monthly — which work out to the equivalent of one extra full payment a year, spread across the calendar rather than paid as a single sum.

The Limit Is in Your Contract, Not a National Standard

There is no single privilege that applies across every Canadian mortgage. “Prepayment privileges vary from lender to lender,” the FCAC's guidance on reducing prepayment penalties states plainly, and the specific percentage is written into your commitment letter, not standardized industry-wide.

As one concrete illustration of how this actually looks: Scotiabank's own published mortgage terms allow homeowners to prepay up to 10%, 15% or 20% of the original principal each year, and to increase the scheduled payment by the same tiered range, depending on which mortgage product they hold. Other major lenders publish their own equivalents, and a restricted-privilege or specialty product can carry a lower privilege than a lender's standard offering. The only way to know your own number is to check the commitment letter you actually signed.

The privilege resets each year on your mortgage's anniversary, and it does not accumulate. If you don't use it one year, the FCAC is direct about what happens: “Typically, you can't carry a prepayment amount from one year to the next. This means you usually can't add the amount you didn't use in previous years to the current year.”

What Happens If You Go Over the Limit

This is where a tool meant to save you money can work against you. Put more toward the mortgage than your privilege allows in a given year, and the FCAC is explicit: “If you put more money toward your mortgage than the maximum amount allows, you will pay a prepayment penalty.”

On most fixed mortgages, that penalty is calculated as the higher of two figures: three months of interest on the outstanding balance, or the interest differential, commonly abbreviated IRD, which compares your existing cost of borrowing against what the lender could charge today for the time remaining on your term. On a longer fixed term taken out when borrowing costs were higher, the IRD can run into the tens of thousands of dollars — which is exactly the arithmetic our Penalty Protector Pro page and its Break or Stay comparison walk through in full.

Variable mortgages are typically simpler here: the penalty for breaking one, or for exceeding a privilege, is usually the three-months'-interest calculation only, without an IRD component, because there's no fixed cost of borrowing to compare against.

Using the Privilege Without Tripping the Penalty

The straightforward way to get the most out of a prepayment privilege is to use as much of it as you can afford every single year, since an unused allowance simply disappears rather than banking for later. A lump sum applied early in the term also does more work than the same sum applied later, because it reduces the principal balance interest is calculated against for the rest of the amortization.

If you're weighing whether to prepay aggressively now versus waiting for your term to end, it's worth knowing that at renewal, there's no prepayment penalty at all for paying out the balance or moving to a new lender — your term has simply ended. That's a different decision than prepaying mid-term, and our Mortgage Renewal page covers what does and doesn't require requalifying when a term comes up.

And if a life change means you need to put a genuinely large sum toward the mortgage — an inheritance, a bonus, the proceeds of a sale — running the numbers before you write the cheque is worth the ten minutes it takes. Our mortgage calculators model a prepayment scenario against your actual balance and term, so you can see whether staying inside the privilege, or paying the penalty to go beyond it, actually comes out ahead.
