How this calculator works

Enter a starting balance, a expected periodic return, and a time horizon — the chart shows what your balance looks like if you reinvest gains instead of withdrawing them. This is the same math behind why consistent small edges compound into large account growth over years, and why drawdowns early on cost more than drawdowns late. It's a planning tool, not a prediction — real returns aren't smooth, and this doesn't account for taxes, fees, or the psychological difficulty of actually staying consistent.
