The best time to make a lump-sum prepayment is in the weeks right before your mortgage matures, not after you sign your renewal. A dollar paid down before renewal shrinks the balance that reprices at your new term’s rate, and it lets you use this year’s prepayment privilege before it resets. Time it after renewal instead and you have already paid interest on the higher balance for longer than you needed to.

What Is a Mortgage Prepayment Privilege?
A prepayment privilege is the amount you are allowed to pay against your mortgage principal each year, on top of your regular payments, without triggering a penalty. Most Canadian lenders set the lump-sum allowance somewhere between 10% and 20% of your original principal balance per year, though a few offer less and some offer more.
The exact percentage, and whether it is calculated against your original balance or your current balance, varies by lender. Many lenders also offer a separate privilege to increase your regular payment amount, sometimes by up to 100% of your original payment, again with terms that differ from lender to lender.
| Privilege type | Typical range | Notes |
|---|---|---|
| Annual lump-sum payment | 10% to 20% of original balance | Varies by lender; some base it on the current balance instead |
| Payment increase | Often up to 100% of the original regular payment | Permanent for the term; varies by lender and product |
| Double-up payments | Usually built into the lump-sum allowance | Not always offered as a separate feature |
Confirm your specific number in your mortgage commitment or with your lender before you plan a payment. A prepayment privilege is the annual allowance to pay down extra principal penalty-free, and the exact percentage always depends on your lender.
Why Timing the Payment Before Renewal Matters
A lump sum applied before your maturity date reduces the balance that carries forward into your new term, so the new rate applies to less money from day one. Apply the same lump sum after renewal instead, and the new, often higher, rate has already been charging interest on the full balance for however many weeks or months passed before you paid it down. The dollar amount of the prepayment does not change, but when you apply it does.
This matters most when your renewal rate is higher than your outgoing rate, which is the situation many homeowners are facing right now. A smaller balance at a higher rate produces less new interest than a larger balance at that same higher rate. If your renewal is landing at a materially higher rate, it is worth reading through your renewal rate options alongside a prepayment plan, since the two strategies work together.
A lump-sum payment made before maturity reduces the principal that reprices at your new renewal rate, while the same payment made after renewal only reduces a balance that has already accrued interest at the new rate. That timing difference is the entire case for paying before, not after.
How the Anniversary Reset Works Around Renewal
Prepayment privileges typically reset on your mortgage’s anniversary date, which is the date your current term began, not on the calendar year and not automatically on your renewal date. Unused privilege room usually does not carry forward once the year passes, though this also varies by lender. Some lenders permit a small carryforward and most do not.
Here is where timing gets interesting. If your anniversary date falls close to your maturity date, you may be able to use the final year’s remaining allowance with a payment just before renewal, then have a fresh allowance open up once your new term begins. Confirm the exact reset date and whether it lines up with your renewal date with your lender or broker, since the two dates are not always the same and the interaction between them varies by lender.
Done correctly, this lets you apply two separate rounds of prepayment room close together around your renewal, rather than losing one year’s unused allowance. The prepayment privilege reset date is tied to your mortgage anniversary, not your renewal date, so the two need to be checked separately.
Worked Example: What a Lump Sum Before Renewal Saves
The following is a strictly illustrative example with round numbers, not a quote or a rate promise. Assume a mortgage balance of $350,000 at maturity, renewing into a new term at 5%, and a lump-sum prepayment of $15,000 made before the renewal date using the current year’s remaining privilege.
| Scenario | Balance entering new term | Approximate first-year interest at 5% |
|---|---|---|
| No prepayment | $350,000 | $17,500 |
| $15,000 lump sum before renewal | $335,000 | $16,750 |
The difference is $750 in first-year interest alone ($17,500 minus $16,750), simply from moving the same $15,000 payment ahead of the renewal date instead of after it. This is a simplified, single-year comparison that ignores monthly compounding and the normal decline in balance from regular payments, so treat it as directional, not a precise amortization schedule. A broker or a mortgage calculator can run the exact figures against your real balance, rate, and remaining amortization.
Reducing your renewal balance by a fixed dollar amount before your rate resets produces a proportional interest saving at the new rate, and that saving repeats every year the smaller balance remains in place.
Lump Sum, Payment Increase, or Both?
A lump sum works well if you have a windfall, a bonus, or savings sitting in a low-interest account earning less than your mortgage rate costs you. A permanent payment increase works better if your income has grown and you want the saving to compound every month rather than in a single hit. Many homeowners use both, applying a lump sum before renewal and raising their regular payment once the new term starts.
Whichever you choose, the underlying math is the same: less principal carried into the new term means less interest charged at the new rate. If you are weighing a lump sum against other uses for the same cash, such as paying down higher-interest debt first, a broker can model the comparison against your actual numbers rather than a general rule of thumb.
What If You’re Also Thinking About Switching Lenders?
A lump-sum prepayment and a lender switch are not mutually exclusive, and doing both around the same renewal date is common. If you plan to switch lenders at maturity, apply your prepayment with your current lender first, since the switch itself does not affect this year’s privilege room with the lender you are leaving. Once you know your new lender’s rate, you can also negotiate your renewal rate using the lower balance as part of the conversation.

Does a Lump Sum Affect Your Penalty If You Break Early?
A smaller balance generally means a smaller penalty if you break your mortgage before maturity, because most penalty formulas are calculated against your outstanding principal. The exact effect depends on which formula your lender uses and where you are in your term. For the full mechanics, see our guide on how mortgage penalty calculations work before you decide whether prepaying or breaking early makes more sense for your situation.
A lower principal balance at the time of a break typically produces a lower penalty, though the calculation method still varies by lender and by mortgage type.
Frequently Asked Questions
How much of my mortgage can I prepay each year without a penalty?
Most Canadian lenders allow a lump-sum prepayment of somewhere between 10% and 20% of your original principal balance each year, on top of your regular payments. The exact percentage, and whether it applies to your original or current balance, varies by lender, so check your mortgage documents or ask your broker for your specific number.
When does my prepayment privilege reset?
Prepayment privileges typically reset on your mortgage’s anniversary date each year, which is tied to when your current term began, not the calendar year or your renewal date. Unused room usually does not carry into the next year, though this also varies by lender.
Does a lump-sum payment reduce my penalty if I break my mortgage early?
In most cases yes, because breaking penalties are generally calculated against your outstanding balance, and a smaller balance can lower the resulting penalty. The exact formula still depends on your lender and mortgage type, so confirm before you decide.
Should I prepay my mortgage or save the cash in case I switch lenders instead?
There is no single right answer, since it depends on your current rate, the rate you expect at renewal, and how much cash you have available. A broker can model a prepayment scenario against a lender-switch scenario using your actual renewal offer before you commit either way.
Can I still make a lump-sum payment in the final weeks before my mortgage matures?
Usually yes, as long as the payment lands before your maturity date and fits within your current term’s remaining privilege allowance. Processing times near maturity vary by lender, so confirm the exact cutoff with your lender or broker with enough lead time.
