Forex Drawdown Calculator
The Drawdown Calculator measures the percentage decline from a peak to a trough balance and the gain needed to recover. Drawdown % = (Peak − Trough) ÷ Peak × 100; Recovery % = (Peak − Trough) ÷ Trough × 100. A separate recovery mode converts any drawdown percentage into the asymmetric gain required to break even.
- Drawdown % = (Peak Balance − Trough Balance) ÷ Peak Balance × 100. Example: $10,000 falling to $7,000 is a 30% drawdown.
- Recovery is asymmetric: required gain = (1 ÷ (1 − drawdown%) − 1) × 100. A 50% drawdown needs a 100% gain, 75% needs 300%, and 90% needs 900% to break even.
- Two modes: Drawdown mode takes peak and trough balances; Recovery mode takes a drawdown percentage (0.1%–99.9%) and returns the gain needed to recover.
- Severity guide: drawdowns up to 10% are mild, up to 30% are serious, and above 30% are dangerous because recovery scales exponentially.
- Maximum drawdown (the largest peak-to-trough decline ever recorded) only increases or stays flat, while current drawdown fluctuates with each new peak.
Calculate your drawdown percentage and discover the exact gain needed to recover. See why protecting capital is the most important rule in trading.
How to Use the Drawdown Calculator
-
Choose Your Mode
Calculate Drawdown takes your peak and trough balances to compute the drawdown percentage and recovery needed. Recovery Calculator takes a drawdown percentage and shows the gain required to recover.
-
Enter Your Balances (Drawdown Mode)
Input the highest balance your account reached (peak) and the lowest point it hit during the drawdown (trough). Select your account currency for dollar amounts.
-
Or Enter Drawdown % (Recovery Mode)
If you already know your drawdown percentage, enter it directly. The calculator shows the exact gain needed and a full reference table.
-
Review the Recovery Asymmetry
The key insight: losses and gains are not symmetrical. A 30% drawdown needs a 42.9% gain to recover — not 30%. The visual chart makes this asymmetry clear.

Set Maximum Acceptable Drawdown
Use the prop firm reference table and strategy guidelines below to determine the maximum drawdown your trading plan should tolerate.
What Is Drawdown in Forex Trading?
Drawdown is the decline from a peak balance to the lowest point before recovery. It's the most important risk metric in trading because it measures your worst-case scenario in real dollars.
Every trader experiences drawdowns. The difference between professionals and amateurs is not avoiding drawdowns entirely — it's limiting their depth so recovery remains realistic.
Why Drawdown Matters More Than Returns
A trader averaging 5% monthly returns but with 50% max drawdown will eventually blow up. A trader averaging 2% monthly with 10% max drawdown will build wealth steadily for decades. Risk-adjusted returns, not raw returns, determine long-term success.
Maximum Drawdown vs Current Drawdown
These two metrics are related but measure different things:
| Metric | Definition | Changes? | Use Case |
|---|---|---|---|
| Current Drawdown | How far below the most recent peak the account is right now | Constantly — goes up and down | Live risk monitoring |
| Maximum Drawdown | The largest peak-to-trough decline ever recorded | Only increases or stays flat | Strategy evaluation, risk assessment |
Maximum drawdown (MDD) is the gold standard for evaluating strategy risk. It tells you: "If I had started at the worst possible time, what's the most I would have lost before recovering?" This number only goes up or stays the same — it never decreases.
Current drawdown is your live indicator. If your current drawdown is approaching your maximum acceptable level, it's time to reduce position sizes or pause trading.
The Recovery Asymmetry Problem
This is the most important concept in trading risk management: losses and gains are not symmetrical. A 50% loss does not require a 50% gain to recover — it requires 100%.
If you lose 50% of $10,000, you have $5,000. To get back to $10,000, you need to gain $5,000 — which is 100% of your current $5,000 balance. The same dollar amount requires twice the percentage gain because your base is now smaller.
This asymmetry accelerates dramatically: a 75% drawdown needs a 300% gain to recover. That's the difference between a bad month and a career-ending event.
| Drawdown | $10,000 Becomes | Recovery Needed | At 5%/Month |
|---|---|---|---|
| 5% | $9,500 | 5.3% | ~1 month |
| 10% | $9,000 | 11.1% | ~2 months |
| 20% | $8,000 | 25.0% | ~5 months |
| 30% | $7,000 | 42.9% | ~7 months |
| 50% | $5,000 | 100.0% | ~14 months |
| 75% | $2,500 | 300.0% | ~29 months |
| 90% | $1,000 | 900.0% | ~48 months |
The "At 5%/Month" column shows how long recovery takes even with excellent performance. A 50% drawdown sets you back over a year. A 90% drawdown takes 4 years of outstanding returns just to break even.
The Key Takeaway
Capital preservation is not optional — it's the foundation of every successful trading career. The math is unforgiving: it's always easier to avoid a drawdown than to recover from one. This is why the 1-2% risk per trade rule exists.
Acceptable Drawdown Levels for Different Strategies
| Strategy Type | Typical Max DD | Risk per Trade | Character |
|---|---|---|---|
| Scalping | 5-10% | 0.25-0.5% | Very tight stops, high win rate |
| Day Trading | 10-15% | 0.5-1% | Multiple trades/day, moderate stops |
| Swing Trading | 15-25% | 1-2% | Wider stops, fewer trades, higher R:R |
| Position Trading | 20-30% | 1-3% | Very wide stops, long hold periods |
| Algorithmic/Quant | 10-20% | Varies | Systematic, diversified, backtested |
These ranges assume proper position sizing. If your drawdown exceeds the typical range for your strategy type, something is wrong — either your risk per trade is too high, your strategy has deteriorated, or you're deviating from your plan.
The Drawdown Circuit Breaker
Many professional traders use a "circuit breaker" rule: if drawdown hits a predefined level (e.g., 15%), they halve their position size until the drawdown recovers to under 10%. Some stop trading entirely until they can review their strategy with a clear head. This prevents a bad week from becoming a blown account.
Prop Firm Drawdown Rules Explained
Proprietary trading firms (prop firms) fund traders with their capital. To manage risk, they enforce strict drawdown limits. Understanding these rules is essential if you trade with funded accounts.
| Firm | Daily Drawdown | Max Drawdown | Drawdown Type |
|---|---|---|---|
| FTMO | 5% | 10% | Balance-based |
| FundedNext | 5% | 10% | Balance-based |
| The Funded Trader | 5% | 10% | Balance-based |
| True Forex Funds | 5% | 10% | Equity-based |
| E8 Funding | 5% | 8% | Balance-based |
| Surge Trading | 5% | 10% | Trailing |
Note: Prop firm rules change frequently. Always verify current rules on the firm's official website before trading.
Understanding Drawdown Types
| Type | How It Works | Example ($100K account) |
|---|---|---|
| Balance-Based | Measured from initial balance; doesn't change with profits | 10% DD limit = can't drop below $90K, ever |
| Equity-Based | Measured from equity including open trades | 10% DD = equity can't go below $90K including floating P&L |
| Trailing | DD limit follows your highest balance upward | If balance hits $105K, floor moves to $95K (105K - 10%) |
Prop Firm Tip
Trailing drawdown is the strictest type because your floor only moves up. If you make $5K profit, your max loss is now $5K less. Many traders fail prop challenges not because they can't trade, but because they don't adapt their risk to trailing drawdown rules. Use this calculator to plan position sizes that keep you within limits.
Frequently Asked Questions
-
Drawdown is the decline from a peak account balance to the lowest point before a new peak is reached. If your account hit a high of $10,000 and then dropped to $7,000, you experienced a 30% drawdown ($3,000 loss from peak). It measures the risk you actually experienced.
-
Drawdown % = (Peak Balance - Trough Balance) / Peak Balance × 100. For example: ($10,000 - $7,000) / $10,000 × 100 = 30%. The trough is the lowest point your account reached during the decline, before any recovery began.
-
Because losses and gains are calculated on different bases. If you lose 50% of $10,000, you have $5,000. To get back to $10,000, you need to gain $5,000 — which is 100% of your remaining $5,000 balance. The smaller your remaining capital, the larger the percentage gain needed to recover. This asymmetry is why capital preservation is the #1 rule in trading.
-
Maximum drawdown (MDD) is the largest peak-to-trough decline in your account history. If your account went from $10,000 to $7,000 (30% DD), recovered to $12,000, then dropped to $10,800 (10% DD), your maximum drawdown is 30%. MDD only increases or stays the same — once recorded, it never decreases.
-
Conservative traders target under 10% maximum drawdown. Moderate strategies tolerate 10-20%. Aggressive strategies may allow 20-30%. Most risk managers consider anything above 30% dangerous because recovery becomes exponentially harder. Professional funds typically have a 20% maximum drawdown limit as a hard stop.
-
Current drawdown is how far below the most recent peak your account sits right now — it fluctuates constantly. Maximum drawdown is the worst peak-to-trough decline ever recorded in your account. Current DD is a live indicator; MDD is a permanent record used for strategy evaluation.
-
Most prop firms enforce two limits: daily drawdown (typically 5%) and overall maximum drawdown (typically 10-12%). Some use balance-based drawdown (from initial balance), while others use trailing drawdown (from highest balance reached). Exceeding either limit usually results in immediate account termination.
-
Five proven methods: (1) Reduce risk per trade to 1% or less. (2) Always use stop losses. (3) Avoid correlated positions that multiply risk. (4) Cut position size during losing streaks. (5) Have a daily loss limit — stop trading after 2-3 losses in a day. The simplest path to lower drawdown is smaller position sizes.
-
The drawdown period (or recovery time) is the duration from when the account peaks to when it recovers back to that peak. A 20% drawdown might take 3-6 months to recover. The length of drawdown periods matters for psychology — even profitable strategies can have multi-month drawdown periods that test trader discipline.
-
Not necessarily, but you should reduce exposure. Many professionals cut position size by 50% when hitting a drawdown threshold (e.g., 10-15%). Stop trading entirely only if: (1) You've lost confidence in your strategy. (2) You're making emotional, revenge-driven decisions. (3) Drawdown exceeds your predefined maximum. Take a break, review your trades, and return with a clear plan.
