Understanding Drawdowns

In short

A drawdown is the percentage drop from an account's peak to its lowest point after that peak. This lesson walks through the recovery-math table showing why deeper drawdowns need disproportionately larger gains to recover from.

Every active trader eventually watches their account fall from a peak. That drop has a name — a drawdown — and understanding the math behind it changes how much it should worry you.

A drawdown is the drop from your account's own peak

A drawdown is the decline from an account's peak value down to its lowest point after that peak, usually shown as a percentage. Every trader who stays active long enough experiences drawdowns. They're a normal, expected part of trading, not automatically a sign something's broken.

A worked calculation

An account grows to a peak of $100,000, then declines to $80,000 before recovering.


Peak value	$100,000
Lowest point after peak	$80,000
Drawdown	($100,000 - $80,000) / $100,000 = 20%

That 20% is measured from the account's own peak, not from where it started. An account that grew from $60,000 to $100,000 and then fell to $80,000 is still up overall from its starting point — even while sitting in a real 20% drawdown from its own high.

Why recovering is harder than it looks

The percentage needed to recover is always bigger than the drawdown itself, and the gap grows sharply as the drawdown deepens:

Drawdown	Gain needed to recover
10%	11.1%
20%	25%
50%	100%
75%	300%

A 50% drawdown doesn't need a 50% gain to break even — it needs a full 100% gain, because the smaller remaining balance has to grow by a much bigger percentage to reach the old peak. That asymmetry is exactly why avoiding deep drawdowns in the first place matters more than it first appears.

A drawdown isn't automatic proof that a strategy is broken — a genuinely sound approach that wins 60% of the time will still, over enough trades, occasionally string together several losses by chance. What tends to turn a normal drawdown into a much deeper one is reacting to it with the exact behaviors covered earlier — revenge trading, abandoning the plan under pressure.

Key takeaway: the deeper a drawdown gets, the disproportionately larger the recovery required — which is why managing risk to avoid deep drawdowns matters as much as picking good trades.

Drawdown math is one reason unrealistic expectations are so costly — that's next.
