A calculator is useful when you want a quick answer. Portfolio Terminal becomes useful when the question stops being hypothetical. If a portfolio has a real peak, a real decline, and a real investor tolerance behind it, the next step is to watch drawdown alongside Value at Risk, holdings concentration, and portfolio history.
That workflow starts with controlled broker import, then moves into the portfolio tracker, drawdown monitoring, and risk review. The goal is not just to explain the math of recovery. The goal is to help you avoid needing extreme recovery in the first place.
