Mortgage calculator
Most calculators quote a payment that is off by a few dollars a month and ignore the cash you need on closing day. This one models the Canadian semi-annual convention, the CMHC premium and its sales tax, and Québec's welcome tax bracket by bracket.
Project type
The property
Financing
Accelerated frequencies pay the equivalent of 13 monthly payments a year and shorten the amortization.
On by default: Canadian fixed-rate mortgages compound twice a year, not monthly.
Extends the insured amortization cap from 25 to 30 years.
Closing costs
Brackets sourced for 2025 — indexed every January.
Ongoing costs
Projection
Drives the projected property value — it does not change your payment.
Mortgage payment plus every recurring cost of owning.
Cash needed at closing
Brackets sourced for 2025 — indexed every January.
The loan
At the end of the 5-year term
The federal stress test qualifies you at the higher of your rate plus 2% or 5.25%.
Equity over time
- Your equity
- Property value
- Balance owed
The shaded gap is your equity — what you would keep if you sold at that year's value.
What can I get approved for?
Uses your income against the GDS and TDS ratios lenders apply, at the stress-test rate.
Car loans, student loans, minimum credit-card payments.
Housing costs are the binding limit here (32% of gross income).
What a Québec home actually costs
Every cost between the offer and the first payment — and the two most calculators get wrong.
