About Northern Numbers

Northern Numbers was built on a simple idea: Canadians deserve financial calculators that actually reflect Canadian rules — not American formulas with a maple leaf slapped on top.

Most calculators online use US tax brackets, US mortgage compounding, and US contribution limits. That's a problem when you're trying to figure out your actual TFSA room, your real mortgage payment under Canadian semi-annual compounding, or how much CMHC insurance will cost you.

Every calculator on this site is built and verified against official Canadian sources — the CRA, CMHC, and Bank of Canada — and updated as rules change each year.

There's no sign-up, no email collection, and no paywall. Your numbers stay on your device. We don't sell your data because we don't collect it in the first place.
