Pay Off Your Mortgage Faster
See how changing your payment frequency, increasing payments, or making lump sums could save you tens of thousands.
Most Canadians pay far more mortgage interest than they need to — not because they can't afford to pay more, but because nobody showed them the math. Switching from monthly to accelerated bi-weekly payments alone can shave years off your amortisation and save tens of thousands in interest. Lump sum payments accelerate this even further.
This calculator models different payoff strategies — accelerated payments, annual lump sums, or a combination — so you can see exactly how many years you can knock off your mortgage and how much interest you'll save. Enter your current mortgage details and explore the scenarios that fit your budget.

Prepayment privileges vary by lender — typically 10–20% annual lump sum and 10–20% payment increase. Exceeding your prepayment privilege triggers penalties. Confirm your lender's specific terms before making extra payments.
How to Pay Off Your Mortgage Faster in Canada
Most Canadians sign a 25-year mortgage and never think about whether they could pay it off sooner. The truth is, small changes to how you pay — not how much you earn — can shave years off your mortgage and save you tens of thousands of dollars in interest. Here are the three most powerful strategies available to Canadian homeowners.
What Is Accelerated Bi-Weekly Payment?
With a standard monthly payment, you make 12 payments per year. Accelerated bi-weekly takes your monthly payment, divides it by two, and you pay that amount every two weeks. Since there are 26 bi-weekly periods in a year, you end up making the equivalent of 13 monthly payments instead of 12. That extra payment goes entirely to principal — not interest — and it compounds year after year.
On a $400,000 mortgage at 4.25%, switching from monthly to accelerated bi-weekly saves over $36,000 in interest and pays off your mortgage more than 3 years early. You barely notice the difference in your budget because each individual payment is smaller than your monthly one — it's just the frequency that changes.
What About Regular Bi-Weekly and Weekly?
Regular bi-weekly and weekly payments split your annual mortgage cost into smaller, more frequent chunks — but the total you pay per year stays the same as monthly. The savings come from a different place: because you're reducing the principal balance more frequently, less interest accrues between payments. The effect is real but modest compared to accelerated bi-weekly, which genuinely increases how much you pay each year.
If budget is tight but you want some benefit from frequency, regular bi-weekly or weekly is better than monthly. If you can handle the slightly higher annual cost, accelerated bi-weekly is the sweet spot.
What Is a Lump Sum Payment?
A lump sum payment — sometimes called a prepayment — is a one-time extra payment that goes directly to your principal balance. Most Canadian lenders allow you to make lump sum payments of 10% to 20% of your original mortgage amount per year without penalty. That means on a $400,000 mortgage, you could put an extra $40,000 to $80,000 per year toward your principal.
Even smaller lump sums make a dramatic difference. A $5,000 annual lump sum on that same $400,000 mortgage can save over $50,000 in interest and take years off the amortization. Tax refunds, bonuses, and annual savings all qualify — it doesn't have to come in one chunk.
Increasing Your Payments Each Year
This is the strategy most people overlook, and it's arguably the most powerful. Most Canadian lenders allow you to increase your regular payment by 10% to 20% per year. If your payment is $2,000/month today and you increase by 10% next year, you're paying $2,200/month — and 10% more the year after that.
The power is in the compounding. A 10% annual increase on a $400,000 mortgage at 4.25% can cut a 25-year mortgage down to under 12 years — saving over $117,000 in interest. You don't feel it year to year because your income is typically rising too, but the effect on your mortgage is massive.
How Canadian Mortgage Interest Works
Canadian mortgages compound semi-annually, not monthly — this is required by law under the Interest Act. That means the effective monthly rate is slightly lower than simply dividing the annual rate by 12. All the calculations on this page use proper Canadian semi-annual compounding, so the numbers you see here match what your lender would calculate.
The Best Strategy? Stack Them.
The real magic happens when you combine all three: accelerated bi-weekly payments, annual payment increases, and lump sum payments. Use the calculator above to see the impact of stacking these strategies on your specific mortgage. The results might surprise you.
Not sure which prepayment options your lender allows? Every mortgage is different. Some lenders offer 10% increase and 10% lump sum. Others go up to 20/20. A few have even more flexibility. Before you sign or renew, talk to a mortgage broker who can show you which lenders offer the best prepayment privileges for your situation — it could save you tens of thousands over the life of your mortgage.
Frequently Asked Questions
Is there a penalty for making extra payments on my mortgage?
Most Canadian mortgages include prepayment privileges that allow you to increase your payment and make lump sum payments up to a certain limit — typically 10% to 20% — without any penalty. If you exceed those limits, a penalty may apply. Your mortgage broker can tell you exactly what your current mortgage allows.
What's the difference between bi-weekly and accelerated bi-weekly?
Regular bi-weekly takes your annual mortgage cost and divides it into 26 payments — you pay the same amount per year as monthly. Accelerated bi-weekly takes your monthly payment, divides by two, and pays that 26 times — meaning you pay the equivalent of one extra monthly payment per year. That's where the savings come from.
Can I switch my payment frequency after I get my mortgage?
Yes — most lenders allow you to change your payment frequency at any time without penalty. You can typically call your lender or log into your online banking to make the switch. If you're unsure, your mortgage broker can coordinate this for you.
When is the best time to make a lump sum payment?
The earlier in the year, the better — because the principal reduction saves you interest for the rest of the year. Many Canadians use their tax refund, annual bonus, or savings to make a lump sum payment early in the calendar year. But any time is better than not making one at all.
Should I pay off my mortgage faster or invest the money instead?
This depends on your mortgage rate, your expected investment return, your risk tolerance, and your tax situation. If your mortgage rate is higher than what you'd earn after tax on investments, paying down the mortgage is the safer bet. A mortgage broker or financial advisor can help you run the numbers for your specific situation.
Does this calculator account for the Canadian stress test?
This calculator shows your actual payment amounts and interest costs at your contract rate — the rate you actually pay. The stress test (contract rate + 2%, or 5.25%, whichever is higher) is used by lenders to qualify you for the mortgage, but it doesn't affect your actual payments.
