Portfolio Drawdown Analyzer
Long-run average return does not tell you how bad the ride gets. This tool focuses on the pain investors actually experience: how deep the portfolio falls, how long it stays underwater, and how quickly it recovers.
Why drawdown analysis changes portfolio decisions
Investors frequently choose portfolios based on return expectations alone. That is incomplete. A strategy can look attractive on average while still being hard to hold through a severe slump. Drawdown metrics expose the downside path so you can judge whether the strategy is survivable for your own time horizon and cash-flow needs.
Peak-to-trough depth is only half the story
A 20% loss that recovers quickly is different from a 20% loss that drags on for years. Recovery time matters for retirement withdrawals, tax-loss harvesting decisions, and simple human behaviour. Many investors abandon otherwise sound plans because the recovery path was longer than they expected.
Use this with conservative assumptions
The best use of a drawdown tool is not to prove that a portfolio is safe. It is to find the points where it becomes uncomfortable or fragile. Test worse sequences than you expect, especially if you plan to withdraw cash during weak markets.
Read this before you trust the average return
The analyzer measures the pain path directly. The guide explains why maximum drawdown, recovery time, and ulcer index often matter more to real investors than average annual return.
Learn how to interpret peak-to-trough declines, why recovery speed matters, and where drawdown analysis changes allocation decisions.

What drawdown tells you that average return does not
Many portfolios look fine when summarized by average return alone. That hides the pain investors actually experience. Drawdown measures how far a portfolio falls from its previous peak before it recovers. That is the risk metric people feel in real life because it captures the size and duration of losing periods.
Why max drawdown matters
Maximum drawdown answers a brutally practical question: what was the worst peak-to-trough decline? A portfolio that earns a healthy long-run return can still be unusable for some investors if it repeatedly falls 30% to 50%. Recovery time matters just as much. A 25% drop that recovers in six months is very different from one that takes four years.
Returns mode vs balance mode
Returns mode is useful when you want to simulate or backtest a sequence of periodic returns. Balance mode is useful when you already have a historical account-value sequence and want to inspect the worst decline directly. The metrics are the same, but the input workflow is different.
How to use this for portfolio decisions
Compare several candidate allocations, stress scenarios, or withdrawal plans. If one strategy has slightly higher average returns but far deeper or longer drawdowns, it may be a worse fit for your risk tolerance or cash-flow needs. This tool is most useful when it helps you reject fragile portfolios before a bad period exposes them.
