About Mortgage Payment Calculator (Canada)
Canadian fixed mortgages compound SEMI-ANNUALLY by law — not monthly like the US — so a quoted 5.2% produces a slightly lower payment than a US-style calculator shows; this tool does the legally-correct conversion. The defaults model $450,000 amortized over 25 years. Canada's defining structure is term ≠ amortization: you amortize over 25 years but commit for a 1–5 year TERM, renewing the remaining balance at whatever rates prevail — the entire interest-rate risk of the middle decades is yours. Renewal is also your leverage point: lenders' first renewal letters are rarely their best offer, and switching at renewal avoids penalties entirely. Insured mortgages (under 20% down) add CMHC premiums of up to ~4% onto the loan; first-time buyers of new builds may access 30-year amortizations. Qualification runs through the stress test: you must qualify at the higher of your contract rate + 2% or the regulatory floor, which effectively shrinks maximum borrowing ~20% versus your real payment. The accelerated-biweekly figure above — half the monthly, paid every two weeks — sneaks in one extra monthly payment a year and typically cuts ~3 years and five figures of interest from a 25-year amortization; most Canadian lenders toggle it free.

Frequently asked questions
Why is my payment different from a US mortgage calculator's?+
Compounding: Canadian fixed rates compound semi-annually (effective monthly rate = (1+rate/2)^(1/6) − 1), US loans monthly. At 5.2% the difference shaves a few dollars per hundred-thousand off versus US math — small monthly, meaningful over 25 years. Use Canadian-specific math (this tool) for offers from Canadian lenders.
Fixed or variable in the Canadian system?+
Variable (prime-linked) historically won more often but carries trigger-rate drama when prime spikes (static-payment variables can hit points where payments no longer cover interest). Fixed buys term-length certainty. With either, the renewal cliff returns every few years — the honest comparison is over your expected ownership horizon, not one term.
What is the penalty for breaking a fixed mortgage early?+
The greater of 3 months' interest or the Interest Rate Differential (IRD) — and big-bank IRD computed off posted rates can reach tens of thousands. If a move or refinance is plausible mid-term, ask lenders to quote their IRD method BEFORE signing; monoline lenders' fair-IRD math is a genuine differentiator.
How does accelerated biweekly actually save years?+
26 half-payments = 13 monthly payments per year — the 13th goes straight to principal. On the defaults that's roughly 3 years off the amortization and a five-figure interest saving. 'Regular biweekly' (monthly × 12 ÷ 26) saves almost nothing — make sure the lender sets the ACCELERATED version.
