This hub has 15 mortgage calculators built around Canadian rules: fixed rates that compound twice a year, terms that usually run five years, insurance on small down payments and a stress test that caps how much you can borrow. Use them to price a purchase, plan payments or size up a renewal. Your lender’s own offer is the figure that counts.
Begin with the mortgage payment calculator to see the regular payment for a given price, rate and amortization.

Does a bi-weekly or weekly payment change the cost?
It can. The newest tool in the hub, the mortgage payment frequency calculator, compares monthly, semi-monthly, bi-weekly, weekly and the two accelerated schedules by total interest, years saved and balance. Run it before you ask the lender to switch, because accelerated payments add up to slightly more over a year.
What rate should I enter?
Type in the offer you’re holding, since rates move often. Under the federal Interest Act, a mortgage has to state its rate calculated yearly or half-yearly, not in advance, and Canadian fixed rates are quoted with half-yearly compounding. The tools apply that by default. Lenders may round payments or use their own day-count rules, so your last payment can differ a little from the schedule. That is normal.
Results follow 2026 federal lending rules.
Frequently asked questions
Why do Canadian mortgages compound twice a year?
The federal Interest Act requires a mortgage to state its rate calculated yearly or half-yearly, not in advance, and Canadian lenders quote fixed rates with half-yearly compounding. The tools use that by default.
How long can the amortization be?
Usually 25 years for insured mortgages. Some situations allow 30 years, and so do uninsured loans. A longer amortization lowers the payment but raises the total interest you pay.
What's the mortgage stress test?
You have to qualify at a higher rate than the one you'll pay, which caps how much you can borrow. The stress test calculator shows the qualifying payment and the income you need.
Is a shorter amortization better?
It raises the payment but cuts total interest sharply. The amortization tool shows both sides, so you can see what you'd save against what the higher payment does to your monthly budget.
Does paying bi-weekly save interest?
Accelerated bi-weekly or weekly payments can pay the mortgage off sooner and cut interest, because you pay slightly more over a year. The payment frequency calculator compares all six options by interest, years saved and balance.
Do I pay a penalty if I break my mortgage early?
Often yes. Lenders usually charge three months of interest or the rate differential on fixed terms, whichever their contract uses. The penalty calculator estimates the cost before you call the lender.
