The 2% Rule - Simple Math That Protects Your Capital
One rule. One number. One decision.
2%
That's all you need to know to protect your trading account.
Let me show you why this simple rule is the difference between survival and destruction.
What Is the 2% Rule?
The 2% Rule: Never risk more than 2% of your account on a single trade.
That's it.
Not 3%. Not 5%. Not 10%.
2%.
The Math
Account: ₹5,00,000
2% Risk: ₹10,000 per trade
Stop Loss: ₹50 away
Position Size: ₹10,000 ÷ ₹50 = 200 shares
If stopped out: Lose exactly ₹10,000 (2%)
Account remaining: ₹4,90,000 (98%)
Why 2%? Why Not More?
The Survival Math
Let's see what happens with different risk levels:
Scenario: 10-Loss Streak (happens to everyone)
At 2% risk per trade:
- Loss 1: ₹5,00,000 → ₹4,90,000 (-2%)
- Loss 2: ₹4,90,000 → ₹4,80,200 (-2%)
- Loss 3: ₹4,80,200 → ₹4,70,596 (-2%)
- ...
- Loss 10: ₹4,08,000 → ₹3,99,840 (-2%)
- Total loss: 20%
- Account survives
At 5% risk per trade:
- Loss 1: ₹5,00,000 → ₹4,75,000 (-5%)
- Loss 2: ₹4,75,000 → ₹4,51,250 (-5%)
- Loss 3: ₹4,51,250 → ₹4,28,688 (-5%)
- ...
- Loss 10: ₹2,99,000 → ₹2,84,000 (-5%)
- Total loss: 43%
- Account damaged
At 10% risk per trade:
- Loss 1: ₹5,00,000 → ₹4,50,000 (-10%)
- Loss 2: ₹4,50,000 → ₹4,05,000 (-10%)
- Loss 3: ₹4,05,000 → ₹3,64,500 (-10%)
- ...
- Loss 10: ₹1,95,000 → ₹1,75,000 (-10%)
- Total loss: 65%
- Account devastated
The Recovery Math
How much do you need to recover?
After 20% loss (2% rule):
- Need +25% to recover
- Achievable with good trading
After 43% loss (5% rule):
- Need +75% to recover
- Very difficult
After 65% loss (10% rule):
- Need +186% to recover
- Nearly impossible
The 2% rule keeps you in the game.
Real Examples
Example 1: Equity Trading
Setup:
- Account: ₹3,00,000
- Stock: RELIANCE
- Entry: ₹2,500
- Stop: ₹2,450 (₹50 away)
2% Calculation:
- Risk amount: ₹3,00,000 × 2% = ₹6,000
- Position size: ₹6,000 ÷ ₹50 = 120 shares
- Investment: 120 × ₹2,500 = ₹3,00,000
- Risk: 120 × ₹50 = ₹6,000 ✓
If stopped out: Lose ₹6,000 (exactly 2%)
Example 2: Options Trading
Setup:
- Account: ₹5,00,000
- NIFTY 24500 CE @ ₹150
- Stop: ₹120 (₹30 away)
- Lot size: 50
2% Calculation:
- Risk amount: ₹5,00,000 × 2% = ₹10,000
- Position size: ₹10,000 ÷ (₹30 × 50) = 6.67 lots
- Round down: 6 lots
- Investment: 6 × 50 × ₹150 = ₹45,000
- Risk: 6 × 50 × ₹30 = ₹9,000 ✓
If stopped out: Lose ₹9,000 (1.8% - even safer)
Example 3: Futures Trading
Setup:
- Account: ₹10,00,000
- NIFTY Futures @ 24,500
- Stop: 24,400 (100 points)
- Lot size: 50
2% Calculation:
- Risk amount: ₹10,00,000 × 2% = ₹20,000
- Position size: ₹20,000 ÷ (100 × 50) = 4 lots
- Investment: 4 × 50 × 24,500 = ₹49,00,000
- Margin required: ~₹2,45,000
- Risk: 4 × 50 × 100 = ₹20,000 ✓
If stopped out: Lose ₹20,000 (exactly 2%)
Common Objections to the 2% Rule
Objection #1: "2% Is Too Small"
"I need bigger positions to make money"
Reality check:
- 2% × 20 trades = 40% of account at risk
- If you win 60% of trades, you're profitable
- Compounding works over time
Example:
- Start: ₹5,00,000
- Win 60% of trades (2% each)
- After 100 trades: ₹8,50,000
- 70% growth with 2% risk
Objection #2: "I'm Confident This Will Work"
"This trade is 100% sure"
Reality:
- No trade is 100% sure
- Even 80% probability trades lose 20% of time
- Confidence ≠ accuracy
Better approach:
- Trade with 2% risk
- If you're right, you make money
- If you're wrong, you survive
Objection #3: "I Need to Make Money Fast"
"I can't wait for slow growth"
Reality:
- Fast money = Fast losses
- Slow money = Sustainable money
- Surviving > Thriving
Math:
- 2% risk: Survive losing streaks
- 10% risk: Blow up account
- Dead traders make 0%
Objection #4: "My Account Is Too Small"
"₹50,000 account, 2% = ₹1,000, too small"
Solutions:
- Build account first (paper trade)
- Use 2% of larger amount (₹1,00,000 = ₹2,000)
- Accept smaller positions (better than blowing up)
Remember: Small account + big risk = No account
Advanced: When to Use Less Than 2%
Use 1% When:
High volatility markets:
- VIX > 20
- Earnings season
- Major news events
Testing new strategies:
- First 20 trades
- Unfamiliar instruments
- Different timeframes
After losses:
- Recent losing streak
- Emotional state compromised
- Account drawdown > 10%
Use 0.5% When:
Account < ₹1,00,000:
- Preserve capital
- Learn without risk
- Build confidence
Very volatile instruments:
- Penny stocks
- Cryptocurrency
- High-beta stocks
The 2% Rule in Practice
Daily Implementation
Before every trade:
- Calculate 2% of account
- Determine stop loss distance
- Calculate position size
- Verify: Risk ≤ 2%
- Enter trade
Example checklist:
Account: ₹5,00,000
2% Risk: ₹10,000
Entry: ₹1,000
Stop: ₹980 (₹20 away)
Position Size: ₹10,000 ÷ ₹20 = 500 shares
Investment: 500 × ₹1,000 = ₹5,00,000
Risk: 500 × ₹20 = ₹10,000 ✓
Weekly Review
Check:
- Did I follow 2% rule every trade?
- What was my average risk per trade?
- Any trades exceeded 2%?
If yes: Why? How to prevent?
Monthly Analysis
Track:
- Total risk taken
- Number of 2%+ trades
- Correlation with losses
Goal: 100% adherence to 2% rule
Portfolio Heat: Multiple Positions
The Problem
You have 3 open positions:
- Position 1: 2% risk
- Position 2: 2% risk
- Position 3: 2% risk
- Total portfolio heat: 6%
This is acceptable.
The Danger Zone
You have 5 open positions:
- Each: 2% risk
- Total portfolio heat: 10%
This is dangerous.
Safe Portfolio Heat Levels
| Total Heat | Assessment | Action |
|---|---|---|
| 0-4% | Very safe | Continue |
| 4-6% | Moderate | Monitor |
| 6-8% | High | Reduce new positions |
| 8-10% | Very high | Stop new trades |
| 10%+ | Danger zone | Close positions |
Rule: Keep total portfolio heat below 6-8%

Same strategy. Different risk management. Different outcome.
The Psychology of 2%
Why It Works
Small losses:
- Don't hurt emotionally
- Don't affect confidence
- Don't trigger revenge trading
- Allow continued trading
Large losses:
- Devastate emotionally
- Destroy confidence
- Trigger revenge trading
- Stop trading
The Compound Effect
Month 1: Follow 2% rule
Month 2: Still following (habit formed)
Month 3: Automatic (no thinking required)
Month 6: Different trader (disciplined)
Month 12: Profitable trader (survived to learn)
Common Mistakes
Mistake #1: "Just This Once"
"This trade is special, I'll risk 5%"
Problem: Once becomes always
Solution: Never exceed 2%. Ever.
Mistake #2: Moving Stops
"I'll widen the stop to 3% risk"
Problem: Defeats the purpose
Solution: Set stop first, then calculate position
Mistake #3: Averaging Down
"I'll add to losing position"
Problem: Increases risk beyond 2%
Solution: One position per trade
Mistake #4: No Stop Loss
"I'll hold until it comes back"
Problem: Risk becomes unlimited
Solution: Always set stop before entry
The Bottom Line
The 2% rule isn't about making money.
It's about staying alive.
You can't make money if you're not trading.
You can't trade if you blow up your account.
The 2% rule ensures you survive to trade another day.
Simple. Powerful. Essential.
