A 50% loss requires a 100% gain to recover. See exactly how hard it is to come back from a drawdown — and why capital preservation matters above all else.
A drawdown is the decline from a peak in your account balance to a subsequent low. It is the single most important measure of trading risk, and it hides a brutal mathematical truth: the gain required to recover from a loss is always larger than the loss itself. Lose 10% and you need 11.1% to get back to even. Lose 25% and you need 33%. Lose 50% and you must double your remaining capital just to return to where you started. This calculator shows you exactly what climb each drawdown demands.
The reason for this asymmetry is simple arithmetic. After a loss you are compounding gains from a smaller base, so the same percentage no longer represents the same number of dollars. A 20% loss on $10,000 leaves $8,000, and a 20% gain on $8,000 is only $1,600 — still $400 short of recovery. The deeper the hole, the steeper and longer the climb out, which is why deep drawdowns so often end trading careers: the recovery becomes mathematically and psychologically out of reach.
This is the core argument for capital preservation as the trader's first job. Avoiding the big loss matters more than catching the big win, because a catastrophic drawdown can erase years of steady gains and require a near-impossible return to undo. Use this tool to internalise that asymmetry — then size your trades so that no single loss, and no single losing streak, can push you into the danger zone.

Losses and gains are not symmetrical. A 10% loss needs only an 11.1% gain to recover. But a 50% loss requires a 100% gain — and a 75% loss requires a 300% gain. This asymmetry is why professional traders obsess over risk management and drawdown limits.
Most prop firms set maximum drawdown limits between 5–10% for this exact reason. Exceeding these limits ends the account — not because the firm is harsh, but because deep drawdowns require near-impossible recoveries.
Anything above 20% becomes psychologically very difficult to recover from. Above 30% is considered dangerous for most strategies. Professional traders aim to keep drawdowns under 10–15%.
Recovery % = (1 ÷ (1 − drawdown%)) − 1, then multiply by 100. Example: 40% drawdown → 1 ÷ 0.60 − 1 = 0.667 = 66.7% needed.
A loss is the result of a single trade. A drawdown measures the cumulative decline from your account's high-water mark, often across many trades. A string of small losses can produce a large drawdown even if no individual trade was disastrous — which is why monitoring the peak-to-trough figure matters more than any one trade's result.
Most funded-account and prop-firm programs set a hard maximum drawdown — commonly 5–10% — and breaching it closes the account immediately. This is not arbitrary cruelty: it reflects the recovery math on this page. By capping drawdown low, the firm ensures any trader who breaches the limit was still in recoverable territory, protecting both sides.
The defence against deep drawdowns is built before the trade, not during it. Risk a small, fixed fraction of your account per trade so that even a long losing streak only dents your balance — risking 1% per trade means ten straight losses cost roughly 10%, an easily recoverable 11% climb. Size every position with the Position Size Calculator and you make a deep drawdown nearly impossible by design.
Equally important is refusing low-quality trades. A positive expectancy and a sound risk/reward ratio keep the equity curve grinding upward instead of giving back gains. Protect the downside relentlessly, and the upside — through compounding — takes care of itself.
