Why CrystalKey is different

Most mortgage calculators are close enough. We wanted exact.

Most calculators use the wrong formula

Canadian mortgages compound semi-annually by law — not monthly like in the US. That difference quietly inflates your estimated payment on most sites. Ours applies the correct Interest Act formula so the numbers you see are the numbers you'll actually pay.

The number that matters is bigger than your down payment

By the time you close, you've paid your down payment, CMHC insurance (if applicable), land transfer tax for your province, GST on a new build, legal fees, and title insurance. We show all of it — not just the easy part.

The rules changed last year. We noticed.

December 2024 brought the biggest mortgage rule update in years: the insured limit went from $1M to $1.5M, GDS limits were raised to 39%, and minimum down payment thresholds shifted. We track every change so you're always working with current rules.
