About
The mortgage calculator banks don't want you to use.
Most calculators online are American — wrong compounding formula, no CMHC, no land transfer tax. Others are built by banks with something to sell. This one is neither.
Correct compounding
Canadian mortgages compound semi-annually under the federal Interest Act — not monthly like American loans. The difference adds up.
Full CMHC math
All premium tiers, the post-Dec 2024 $1.5M cap, and the 30-year amortization rule for first-time buyers of new builds.
Every province's LTT
Ontario, BC, Quebec, Toronto's double tax, and all first-time buyer rebates — calculated to the dollar.
Built on one premise
Buying a home is the largest financial commitment most people will ever make. The numbers you use to plan should match the numbers on your mortgage commitment letter — not be off because someone copied a formula from an American textbook.
This calculator treats accuracy as the only non-negotiable. If a calculation doesn't match a bank's spreadsheet to the dollar, it's wrong, and it gets fixed.
Three rules, full stop
Free, no signup. No paywall. No account. If you can read it, you can use it.
No data harvesting. The numbers you type stay in your browser. I don't ask for your email, and I don't track your inputs.
No lender referrals. I don't sell leads or take referral fees. The results aren't shaped by any commercial relationship — they're just math.
