Three calculators, one page: how many years until you're financially independent, how your portfolio compounds, and how deep your worst drawdown has actually been.

Project a lump sum plus recurring contributions forward at a given return rate.
Paste a series of portfolio values (comma-separated, in order over time) to see the largest peak-to-trough decline.
