What nobody tells you about your first paycheque
CPP, EI, TFSA, RRSP — nobody hands you a glossary.
NNobody 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 actually knows Canadian tax — all 13 provinces and territories, 2025 federal and provincial brackets, CPP, EI, and what an RRSP contribution actually does to your take-home pay, verified line by line against CRA's own tables. Not an estimate. The real math.
An app that tracks your money and one that explains your money are different products. Most only do the first.
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, not six tabs pretending to be one app.
It's built for anyone landing their first full-time Canadian salary, because that's a specific enough problem that the generic finance apps never quite fit it. 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.'
