Free Canadian mortgage tools
Every calculator here runs on the engine the app itself runs on — semi-annual compounding, prepayment privileges that reset on the anniversary, and the posted-rate method the big banks price a break at. None of them asks you to create an account.
Mortgage penalty calculator
Free Canadian break-cost calculator: three months' interest against the interest rate differential, modelling both the posted-rate method the big banks use and the offered-rate method monolines use. No account, and nothing you type is stored.
Affordability calculator
Free Canadian affordability calculator, tested at the stress-test rate: GDS and TDS, the default-insurance premium, and land transfer tax. No account, and nothing you type is stored.
Mortgage stress test calculator
Free Canadian mortgage stress test calculator: your qualifying rate, the payment a lender tests instead of the one you would make, and the income two ratio bands ask for — plus whether the rule reaches your renewal or your switch at all. No account, and nothing you type is stored.
Mortgage prepayment calculator
Free Canadian prepayment calculator: what a lump sum or a payment increase saves you, and — the part almost nothing else models — how much your privileges actually allow, including whether your term gives you two budgets or one shared cap. No account, and nothing you type is stored.
Trigger rate calculator
Free trigger rate calculator for Canadian variable-rate mortgages with fixed payments: how far rates can rise before your payment stops covering interest, and what a voluntary increase buys you. No account, and nothing you type is stored.
Land transfer tax calculator
Free Canadian land transfer tax calculator: provincial duty plus Toronto's and Montréal's municipal duty, net of the first-time-buyer rebates. Five provinces estimated, and the rest say why rather than showing zero.
CMHC insurance calculator
Free Canadian mortgage default insurance calculator: the CMHC, Sagen and Canada Guaranty premium on your down payment, the provincial tax on it that is due in cash, and the band boundary where a hundred dollars of down payment is worth thousands. No account, and nothing you type is stored.
Behind the arithmetic
Each of these numbers comes from a rule somebody wrote down. The explainers state the method, name the statute or the regulator it comes from, and work an example through the same engine.

Every lender's contract governs its own mortgage, and the figures here are estimates from stated assumptions rather than quotes. Confirm anything you intend to act on with your lender and a licensed professional.
