What nobody tells you about your first paycheque

CPP, EI, TFSA, RRSP: nobody hands you a glossary.

Nobody sits you down before your first real paycheque and explains why the number on the offer letter isn't the number that shows up in your account. You just find out, badly, usually mid-panic, usually via a Reddit thread with contradictory answers in every comment.

So I built the thing I wish had existed: a salary calculator that knows about Canadian tax, covering all 13 provinces and territories, federal and provincial brackets, CPP, EI, and what an RRSP contribution actually does to your take-home pay. It's an estimate, and the app says so, but it's a much better estimate than a Reddit thread.

The tax calculator was never going to be enough on its own, so I built five other modules around it: budget tracking, savings goals with actual templates (TFSA maxout, emergency fund, first home), and a 40-term glossary you can hover instead of googling. All six share one Supabase user record, so your budget knows about your salary and your goals know about your budget. One financial picture across all six.

It's built for anyone landing their first full-time Canadian salary, because generic finance apps never quite fit that problem. I'm not solving inflation. I'm solving 'wait, what's the difference between a TFSA and an RRSP, and why is everyone acting like I should already know.'
