Mortgage Payment Calculator
Run any balance, rate, and amortization, see the payment at every Canadian payment frequency, and check what accelerated bi-weekly takes off the schedule. Math uses Canadian semi-annual compounding, the way the lender actually books interest.
Accelerated bi-weekly payment
$1,709.13
26 payments per year. Mortgage paid in full in 21.6 years.
Compare every frequency
Same balance, same rate, same amortization. Different cadences. The two “accelerated” rows are the ones most clients are leaving on the table.
| Frequency | Payment | Years | Total interest |
|---|---|---|---|
| Monthly | $3,418.25 | 25 | $425,475 |
| Bi-weekly | $1,575.98 | 25 | $424,386 |
| Accelerated bi-weekly | $1,709.13 | 21.6 | $358,353 |
| Weekly | $787.63 | 25 | $423,920 |
| Accelerated weekly | $854.56 | 21.6 | $357,595 |
Switching from monthly to accelerated bi-weekly
3.4 years off the schedule.
About $67,122 less interest paid over the life of the mortgage. No rate change, no product change, no extra application. Same monthly cost, paid every two weeks instead.
Balance over time
Year-end balance, monthly vs accelerated bi-weekly. The gap is the strategy.
What this calculator misses
The headline payment number is the easy part. The conversation that actually moves the file is which product, which term, which lender, and what the prepayment privileges look like in five years when the file might want to refinance. Rate-shopping a quote without knowing which structure fits is how clients end up paying penalties that wipe out years of savings.
If you're renewing in the next 90 to 120 days, or weighing a new purchase, that's a strategy call. No pressure, just a conversation.
