Compound interest calculator
Project a starting balance and a regular contribution. Fees come off the return, and today's dollars show what the result buys after inflation. Tax and contribution room are left out, so the same return grows any account the same way.

A 0.20% fee costs $34,894 over 30 years. With no fee the portfolio finishes at $912,535.
Assumptions & limitations
- Returns are annualized and compound monthly. A 7% return with no contributions leaves the balance 7% higher after a year.
- Fees come off the annual return before compounding. A 7% return and a 0.20% fee compounds at 6.80%.
- Contributions stay flat through the year, then rise by the annual increase at each anniversary.
- Beginning deposits the contribution before that period's return. End deposits it after.
- Today's dollars divide each balance by inflation since the start, and value each deposit by the purchasing power it had when it went in.
- The goal is a nominal balance. The year shown is the first year-end at or above it.
- Taxes, contribution limits, and the path of returns are left out. A TFSA, RRSP, FHSA, and non-registered account with the same return grow the same amount here.
- This is an educational model, not financial advice. Past returns don't decide what you earn next.
