Show HN: Calcu-gator.com – Financial calculators for Canadians

https://calcu-gator.com/
4•Nitromax•1mo ago
I built a suite of financial calculators specifically for the Canadian market. Unlike generic tools, these handle Canadian tax brackets, RRSP/TFSA rules, provincial variations, and local mortgage regulations.

Key features:

- Canadian income tax calculator (federal + provincial)

- Mortgage calculator with CMHC insurance

- RRSP/TFSA contribution planners

- All calculations stay in your browser (no data sent to servers)

Built with React and designed for speed and accuracy. Open to feedback from the HN community!
