What Is a Drawdown? Drawdown vs. Pullback in Trading
By Forex & Brokers DeskUpdated Nov 10, 2026
Definition
A drawdown is the decline in the value of an investment, trading account or fund from a peak to its lowest point before that peak is regained, usually quoted as a percentage of the peak.
Key takeaways
- Drawdown equals peak value minus trough value, divided by peak value, times 100.
- A 50% drawdown requires a 100% gain just to return to the previous peak.
- Maximum drawdown is the largest peak-to-trough decline over a period, used to compare funds and strategies.
- The Calmar ratio divides annualized return by maximum drawdown, rewarding returns earned with shallower declines.
A drawdown is the decline in the value of an investment, trading account or fund from a peak to the lowest point (trough) reached before that peak is regained. It is usually quoted as a percentage of the peak. A drawdown measures how far value fell from its high point, not how much money you lost against what you paid, and it is not finished until value recovers to the old peak.
How a Drawdown Works
The formula is:
Drawdown (%) = (Peak value − Trough value) ÷ Peak value × 100
Suppose an account reaches $20,000, falls to $18,000 and later climbs back to $20,000. The drawdown is ($20,000 − $18,000) ÷ $20,000 = 10%.
Two points about timing follow from the definition. First, the trough is only confirmed once value returns to the prior peak. While the account is still below its high, a lower low is possible, so any drawdown measured mid-decline is provisional. Second, a new drawdown can only start after a new peak is set. Every peak-to-trough cycle produces its own figure, and the largest of them over a given period is called the maximum drawdown (MDD).
Interpreting a Drawdown
The percentage alone understates the damage, because recovery is measured from a smaller base. The gain needed to return to the peak is:
Required gain = Drawdown ÷ (1 − Drawdown)
| Drawdown | Gain needed to recover |
|---|---|
| 1% | 1.01% |
| 10% | 11.1% |
| 20% | 25% |
| 30% | 42.9% |
| 50% | 100% |
| 75% | 300% |
Small drawdowns are close to symmetrical. Large ones are not. An account that loses half its value has to double just to break even, which is why traders treat deep drawdowns as more than proportionally harmful. Strategies that add to losing positions, such as the Martingale strategy, can produce long stretches of small gains followed by a drawdown that the recovery math makes very hard to undo.
The second dimension is duration: how long it takes to go from the peak to the trough and back. Two funds with the same 20% maximum drawdown are not equally risky if one recovered in months and the other took years. Recovery speed depends on market conditions and on the specific investment, and assets differ widely in how quickly they have historically regained their highs.
Drawdown vs. Pullback
The two terms overlap but answer different questions.
A pullback is a description of price behavior: a temporary decline against a prevailing uptrend, after which the trend is expected to resume. Technical traders use the word when reading charts, often to look for entries. Calling a move a pullback carries a view about what happens next.
A drawdown is a measurement. It records how far an account, portfolio, strategy or asset fell from its peak, with no assumption about whether the decline is temporary. It applies to anything with a value history, including a trading account that holds many positions or short trades that lose when prices rise.
The two can describe the same event from different angles. If you hold a stock long and it pulls back from $50 to $45 before resuming its rise, the pullback is in the price chart and the 10% drawdown is in your position. But a pullback that keeps falling stops being a pullback (it becomes a reversal or a correction), while the drawdown simply keeps getting deeper until a trough is confirmed.
Why Is a Drawdown Important?
Standard deviation treats upside and downside moves alike. Drawdown focuses only on the declines investors actually have to sit through, which makes it a common input for risk analysis:
- Comparing funds and strategies. Maximum drawdown shows the worst historical peak-to-trough decline a manager or system experienced.
- Risk-adjusted ratios. The Calmar ratio divides annualized return by maximum drawdown. The Sterling ratio compares return to average drawdown. Both reward returns earned with shallower declines.
- The Ulcer Index. This indicator combines the depth and duration of drawdowns into one number, so a long, grinding decline scores worse than a brief dip of the same size.
- Trading account rules. Traders often cap how much drawdown they will accept before cutting size or stopping. Funded and prop firm accounts may impose drawdown limits as part of their terms, and the exact rule (for example, whether it is measured on balance or on equity including open trades, and whether it is fixed or trails new highs) determines when an account is breached. Read those terms as written for the specific program.
Drawdown is managed mainly through position sizing and exits. A position size calculator ties the amount at risk per trade to a set percentage of the account, and a stop-loss order defines where a losing trade is closed. On leveraged accounts, a deep drawdown in equity can also lead to a margin call before the trader decides to act.
Example of a Drawdown
Hypothetical example. A trader buys shares at $100. The price rises to $110, falls to $80, and then recovers to $110 without going lower.
- Peak: $110. Trough: $80.
- Drawdown: ($110 − $80) ÷ $110 = 27.3%.
- Unrealized loss at the trough: $100 − $80 = $20 per share, or 20% of the purchase price.
The drawdown is larger than the loss because it is measured from the peak, not from the entry price. The trader never realized any loss if they held through the recovery.
If the price then rises to a new peak of $120, drops to $105 and recovers to $120, that is a separate drawdown of $15, or 12.5%. The maximum drawdown across both cycles remains 27.3%.
Limitations of a Drawdown
- It is backward-looking. Historical maximum drawdown is the worst decline so far. A future drawdown can be deeper.
- It depends on the window. A short sample may miss a severe decline that a longer history would include.
- One number hides the path. A single maximum drawdown says nothing about how often smaller drawdowns occurred or how long recovery took, unless duration is reported alongside it.
Retirement Drawdowns
In retirement planning, the word has a second meaning: drawdown (or pension drawdown) is the process of withdrawing income from a retirement account or pension pot while the rest stays invested. It is an activity, not a measurement of decline.
The two meanings interact. Retirees have less time to wait for a market drawdown to recover, and withdrawals taken during a decline sell assets at lower prices, which deepens the hole the remaining portfolio has to climb out of. For that reason, investors with short horizons often compare a fund’s historical maximum drawdown with the decline they could tolerate before investing, and spread holdings across stocks, bonds, cash and other assets that do not all fall at the same time.
The Bottom Line
Drawdown matters to traders, fund investors and retirees because deep declines need far larger gains to recover and can take years to repair. Position sizing and stop-loss orders are the main tools for limiting it, and prop firm traders should read their program's exact drawdown rules. Since historical maximum drawdown only shows the worst decline so far, investors should check recovery time as well and allow for a deeper fall in the future.
