How our calculators do the math

Most Canadian mortgage calculators run American math behind a Canadian domain. Ours use the Canadian rules below.

Semi-annual compounding
Canadian fixed-rate mortgages compound semi-annually, not in advance, under section 6 of the federal Interest Act. Variable rates compound monthly. We model the two separately.
All 6 payment frequencies
That includes accelerated bi-weekly and accelerated weekly. We derive them from the monthly payment the way lenders do, which is why they add up to 13 monthly payments a year.
The OSFI stress test
We test at the greater of your contract rate plus 2 points or the 5.25% floor, and apply the November 2024 exemption for uninsured straight switches.
Alberta's current fee schedule
$50 plus $5 per $5,000 on the transfer and again on the mortgage, in force since 20 October 2024. Several national calculators still show the old, lower fees.
Effective-dated rules
Every premium tier, tax bracket and fee formula has an effective date and a source URL. When a rule changes, a scenario saved under the old rule still gives the same result.
Checked against published examples
We test the payment engine against independently published worked examples, and run regression and property tests on the calculator rules.
