Drawdown Calculator

A drawdown is the decline in your trading account balance from its peak (highest point) to its lowest point before a new peak is reached. For example, if your account grows to $20,000 and then drops to $16,000 before recovering, you experienced a 20% drawdown. Drawdowns are a normal and expected part of trading, but their severity determines how difficult recovery will be. Understanding drawdowns is essential for both retail traders and prop firm participants. Our drawdown explained article covers the concept in depth, including the different types and how they're measured.

This is due to the asymmetry of percentage losses and gains. If you lose 25% of your account, you now have 75% remaining. To get back to your original balance, you need to earn 33.3% on that remaining 75% — not 25%. The larger the drawdown, the more extreme this asymmetry becomes: a 50% loss requires a 100% gain to recover, and a 75% loss requires a 300% gain. This is the key insight the drawdown calculator demonstrates. Preventing large drawdowns is far more important than chasing big gains. Learn more about this critical dynamic in our risk management mistakes guide.

Most prop firms set two drawdown limits: a daily drawdown limit (typically 4–5%) and a maximum (trailing) drawdown limit (typically 8–10%). The daily limit resets each day at midnight server time, while the maximum limit is usually trailing — meaning it follows your account equity peak upward but never decreases. Exceeding either limit results in immediate disqualification. The drawdown calculator helps you understand how quickly recovery becomes mathematically difficult once you approach these limits.

The most effective way to reduce drawdowns is strict position sizing — never risk more than 1–2% of your account on a single trade. Use our risk calculator to verify your dollar risk before every entry. Other strategies include widening your stop losses on lower-timeframe strategies to avoid noise, reducing position size during volatile market conditions (like major news events), and taking breaks after consecutive losses to avoid revenge trading. Diversifying across non-correlated pairs can also smooth out your equity curve. A well-maintained trading journal helps you identify patterns that lead to drawdowns.

Relative drawdown measures the peak-to-trough decline as a percentage of your peak balance, which is what this calculator focuses on. Absolute drawdown measures the difference between your initial deposit and the lowest point your account has reached. For example, if you deposited $10,000, grew it to $15,000, then dropped to $12,000, your relative drawdown is 20% (from $15K to $12K) but your absolute drawdown is only $2,000 (from $10K deposit to $8K net, though in this case the account never went below the deposit). Prop firms typically use relative drawdown for their trailing limits. Our drawdown article explains these measurements in detail.

For most retail traders, drawdowns of 10–20% occur occasionally even with good risk management, especially during losing streaks that are statistically normal in any trading system. However, a 10% drawdown requires nearly 11% just to break even, and it signals that you should review your recent trades for errors or market conditions that don't suit your strategy. For prop firm traders, a 10% drawdown often means account termination since most firms cap maximum drawdown at 8–10%. Use our lot size calculator to ensure you're sizing positions appropriately to keep drawdowns manageable.

Drawdowns directly impact compound growth because you're compounding from a lower base after a loss. If you're using our compound calculator to project long-term gains, factoring in realistic drawdowns gives you a much more accurate expectation. A strategy that compounds at 5% monthly will look very different if you subtract a 15% drawdown that occurs once a year. The drawdown calculator helps you model these setbacks so your growth projections aren't overly optimistic. Understanding the interplay between drawdowns and compounding is key to realistic trading expectations.

No. This calculator provides a mathematical illustration of the relationship between percentage losses and the gains required to recover. It is designed for educational and planning purposes only and does not predict future market performance or guarantee that your account will recover from any drawdown. Actual trading involves risks including slippage, gaps, black swan events, and psychological factors that this tool cannot model.
