Frequently Asked Questions

About This Calculator

v1.0
Updated: October 2025

The Canadian Mortgage Optimizer Calculator is a powerful tool for homeowners looking to pay off their mortgage faster and save thousands in interest costs through strategic prepayments and accelerated payment schedules. Canadian mortgages have unique features compared to US mortgages, including semi-annual compounding, prepayment privileges (typically 15-20% annually), and accelerated bi-weekly payment options that can shave years off your amortization. This calculator models multiple mortgage payoff strategies including lump sum prepayments, increased regular payments, accelerated bi-weekly payments, and mortgage term renewal scenarios. By exploring different prepayment scenarios, you can see exactly how much interest you'll save and how many years faster you can become mortgage-free. The calculator also helps you optimize the timing of prepayments - should you make a lump sum payment now or invest the money and make smaller regular prepayments? Understanding these trade-offs is key to making informed decisions about one of the largest financial obligations most Canadians face.
