Hey PH! 👋
I built this after running my own mortgage numbers and being shocked by how much goes to interest in the early years.
Most people only see the monthly payment — this tool shows the full picture over your entire amortization.
100% free, no signup, no ads. Would love your honest feedback — especially from anyone who's gone through the Canadian mortgage process!
