A drawdown is the decline in an account's value from its highest recorded point, called its peak, to a later low point. It is usually expressed as a percentage of that peak. If an account rises to $10,000 and then falls to $9,000, it has a 10% drawdown. The key lesson is simple but often misunderstood: recovering from a loss requires a larger percentage gain than the percentage lost.
This difference comes from a changing base. A 10% loss removes money from the original account value. The recovery percentage is then calculated from the smaller remaining balance. As drawdown deepens, recovery becomes progressively harder. This is why controlling losses is a core part of risk management, not a secondary concern after choosing entries.
How drawdown is measured
Use the account's highest equity value as the reference point. Equity includes open profit or loss, while balance usually changes only after trades close. For a complete view of risk, tracking equity is often more useful because it shows losses that are still open.
The formula is:
Drawdown percentage = (peak equity minus current equity) divided by peak equity, multiplied by 100.
Imagine a $1,000 account reaches a peak of $1,200, then declines to $1,080. The decline is $120. Divide $120 by the $1,200 peak: 0.10. Multiply by 100, and the drawdown is 10%.
Drawdown is different from an individual losing trade. One trade can cause a drawdown, but so can a sequence of smaller losses, trading costs, or an open position moving against the account. A trader may also have a losing trade while remaining above an earlier account peak, in which case there is no drawdown from that higher peak.
The recovery math behind a loss
The recovery percentage answers a specific question: what percentage return must the remaining account earn to return to its previous peak? The formula is:
Required recovery percentage = drawdown percentage divided by (100 minus drawdown percentage), multiplied by 100.
Here is a practical recovery math table. Each figure assumes no deposits or withdrawals, and it ignores costs so the relationship is easy to see.
- A 5% drawdown needs a 5.3% gain to recover.
- A 10% drawdown needs an 11.1% gain to recover.
- A 20% drawdown needs a 25% gain to recover.
- A 30% drawdown needs a 42.9% gain to recover.
- A 40% drawdown needs a 66.7% gain to recover.
- A 50% drawdown needs a 100% gain to recover.
- A 60% drawdown needs a 150% gain to recover.
The pattern matters more than memorising every number. A small drawdown may be manageable within a tested trading plan. A large drawdown can pressure a trader to take oversized positions, trade too frequently, or abandon rules. Those reactions can turn a mathematical problem into a behavioural one.
Worked hypothetical example
Imagine a $1,000 account loses 25%. Its value becomes $750, because $1,000 multiplied by 0.25 equals $250, and $1,000 minus $250 equals $750. To get back to $1,000, the account must gain $250.
Calculate the needed return from the remaining balance: $250 divided by $750 equals 0.3333. Multiplied by 100, that is a required gain of 33.3%. A 25% loss therefore needs a 33.3% recovery. Earning 25% on $750 would add only $187.50, leaving the account at $937.50 rather than its former peak.
Why limiting losses matters more than chasing recovery
Recovery math does not mean a trader should try to regain losses quickly. It shows why a plan should aim to keep losses small enough that normal, disciplined trading can continue. Markets can remain uncertain, spreads and fees can reduce results, and a valid strategy can experience a losing sequence. No position size removes that risk.
Set a maximum amount of account equity to risk before entering a trade. That amount should be based on the distance to the stop loss and the position size, not on how strongly a trade idea feels. If the required position size is too large for the planned risk, reduce the size or skip the trade.
A second control is a drawdown limit for a day, week, or strategy review period. The limit is not a prediction that losses will stop at that point. It is a rule that pauses new risk so the trader can inspect whether execution, market conditions, or the strategy itself has changed.
Common drawdown mistakes
- Using the starting balance instead of the peak: drawdown is measured from the highest account value reached before the decline.
- Treating equal loss and recovery percentages as equal: a 20% gain does not repair a 20% loss.
- Increasing position size after losses: this can deepen drawdown rapidly if the next trade also loses.
- Ignoring open losses: balance may look stable while equity is already under stress.
- Changing a tested system during a normal losing run: first compare the drawdown with the system's historical testing and stated risk limits.
- Trying to recover in one trade: one large position can create a much larger loss than the original problem.
A practical drawdown routine
- Record the account's peak equity after each trading session.
- Calculate current drawdown from that peak and note the percentage.
- Compare it with your prewritten risk limit and reduce or pause new trades if that limit is reached.
- Review position size, stop-loss adherence, costs, and whether trades followed the plan.
- Resume only with the same measured risk process, rather than trying to force a rapid recovery.
Keeping drawdown contained cannot ensure profits, but it preserves more capital and more decision-making room when trades do not work as planned.
