See what your mortgage costs across 25 years. Three charts: balance-over-time curve, principal-vs-interest split, and accelerated-payment savings. Built with Canadian semi-annual compounding rules.
Accelerated bi-weekly = monthly ÷ 2, but paid 26 × per year (52 weeks ÷ 2). That's one extra month's payment per year applied DIRECTLY to principal. Shaves ~3 years off a 25-year mortgage.
