Intraday P&L Calculator 2025-26

STEP 1: Enter Your Trade Details

📝 What You Input:

📌 Example Input:
• Buy Price: ₹500
• Sell Price: ₹510 (2% gain)
• Quantity: 100 shares
• Leverage: 5x (MIS)
• Exchange: NSE
• Brokerage: ₹20 per order

💡 Pro Tip: Intraday trades use MIS (Margin Intraday Square-off) with higher leverage. You must square off before market close (3:20 PM IST). Use the scenario buttons (Base, Volatile, Normal) for quick testing.

STEP 2: Calculate Gross Profit/Loss

🧮 The Formula:

⚠️ Loss Scenario: If Sell Price < Buy Price, Gross P&L is negative. For example, selling at ₹490 (down ₹10) = -₹1,000 loss. You still pay charges even on losses!

STEP 3: Calculate Margin Required (with Leverage)

💰 The Formula:

📌 Why Margin Matters: ROI is calculated on margin, not total capital. Higher leverage amplifies returns: ₹1,000 profit on ₹10,000 margin = 10% ROI (vs 2% on full ₹50,000).

STEP 4: Calculate All Charges & Taxes

📋 Charges Breakdown (2025):

⚖️ Key Insight: Even small trades face multiple charges. This is why price movement must exceed “break-even” to be profitable. For this ₹1,000 gain, break-even price is only (500 + 0.68) = ₹500.68.

STEP 5: Calculate Net P&L & ROI

🎯 Final Formulas:

💡 Take Away: This is why intraday traders use leverage—small price moves create amplified returns on margin. But remember: losses are also amplified equally!

STEP 6: Run Monte Carlo Simulation (100 Scenarios)

🎲 What is Monte Carlo?

🎯 Use Case: Before entering a trade, click “Monte Carlo” to see: Is my win probability at least 50%+? Are my potential gains worth the risk? This helps separate good trades from risky bets.

EXAMPLE 1: Conservative Trade – RELIANCE (NSE)

📋 Trade Setup:

• Stock: RELIANCE
• Buy Price: ₹2,500 (9:15 AM)
• Sell Price: ₹2,510 (12:30 PM) — Target: 0.4% gain
• Quantity: 50 shares
• Leverage: 5x (MIS)
• Exchange: NSE
• Brokerage: ₹20/order (Zerodha flat)

💡 Calculator Analysis:

Step 1 – Gross P&L: (₹2,510 – ₹2,500) × 50 = ₹500

Step 2 – Trade Value: ₹2,500 × 50 = ₹1,25,000
Margin Required (5x): ₹1,25,000 ÷ 5 = ₹25,000

Step 3 – Charges Breakdown:
• Brokerage (2 orders): ₹40
• STT (0.025% on sell): ₹3.13
• Txn Charge (NSE 0.00322%): ₹4.03
• SEBI Fee: ₹0.13
• Stamp Duty (0.003%): ₹0.38
• GST (18%): ₹0.88
Total Charges: ₹48.55

Step 4 – Net P&L: ₹500 – ₹48.55 = ₹451.45
ROI: (₹451.45 ÷ ₹25,000) × 100 = 1.81%

Result: A safe 0.4% price move = 1.81% return on margin with 5x leverage. Win probability from Monte Carlo: ~72%.

📌 Key Takeaway: RELIANCE is highly liquid (low slippage). Even small moves are achievable. This trade requires careful timing but has low risk. Perfect for conservative day traders.

EXAMPLE 2: Aggressive Trade – BANKNIFTY (NSE, Highly Volatile)

📋 Trade Setup:

• Stock: BANKNIFTY ETF
• Buy Price: ₹300 (9:20 AM, post-open volatility)
• Sell Price: ₹315 (11:00 AM) — Target: 5% gain
• Quantity: 200 shares
• Leverage: 10x (MIS maximum for mid-cap)
• Exchange: NSE
• Brokerage: ₹20/order

💡 Calculator Analysis:

Step 1 – Gross P&L: (₹315 – ₹300) × 200 = ₹3,000

Step 2 – Trade Value: ₹300 × 200 = ₹60,000
Margin Required (10x): ₹60,000 ÷ 10 = ₹6,000

Step 3 – Charges Breakdown:
• Brokerage (2 orders): ₹40
• STT (0.025% on sell): ₹15.75
• Txn Charge (NSE 0.00322%): ₹1.93
• SEBI Fee: ₹0.06
• Stamp Duty (0.003%): ₹0.18
• GST (18%): ₹1.04
Total Charges: ₹58.96

Step 4 – Net P&L: ₹3,000 – ₹58.96 = ₹2,941.04
ROI: (₹2,941.04 ÷ ₹6,000) × 100 = 49.02%

Result: A 5% price move with 10x leverage = 49% return on ₹6,000 margin! But Monte Carlo shows: Win probability only ~45% (higher risk).

⚠️ Key Takeaway: Higher leverage + volatile stock = huge returns but also huge risk. A 5% adverse move = -49% loss! This trade works only if you’re right AND have iron discipline. Not for beginners.

EXAMPLE 3: Failed Trade – TCS (Loss + Charges)

📋 Trade Setup (What Went Wrong):

• Stock: TCS
• Buy Price: ₹3,500 (10:00 AM on positive news)
• Sell Price: ₹3,480 (10:45 AM) — Unexpected sell-off (-0.57%)
• Quantity: 75 shares
• Leverage: 7x (MIS)
• Exchange: NSE
• Brokerage: ₹20/order

💡 Calculator Analysis:

Step 1 – Gross P&L: (₹3,480 – ₹3,500) × 75 = -₹1,500 (LOSS!)

Step 2 – Trade Value: ₹3,500 × 75 = ₹2,62,500
Margin Required (7x): ₹2,62,500 ÷ 7 = ₹37,500

Step 3 – Charges Breakdown:
• Brokerage (2 orders): ₹40
• STT (0.025% on sell): ₹8.70
• Txn Charge (NSE 0.00322%): ₹16.88
• SEBI Fee: ₹0.17
• Stamp Duty (0.003%): ₹0.79
• GST (18%): ₹1.47
Total Charges: ₹68.01

Step 4 – NET LOSS: -₹1,500 – ₹68.01 = -₹1,568.01
ROI: (-₹1,568.01 ÷ ₹37,500) × 100 = -4.18%

Result: You were wrong by just 0.57%. With 7x leverage, this = -4.18% loss on margin. You still pay ₹68 in charges even though you lost money!

📌 Critical Lesson: This is why stop losses are MANDATORY. A 0.5% adverse move can wipe out weeks of small profits. This trade should have been exited at -₹750 loss (after charges). The Monte Carlo for this setup showed only 40% win probability—not worth the risk!

⚡ Life-Changing Takeaway: Many traders lose money not because of trades, but because they don’t use stop losses. After losing ₹1,568 on this ONE failed trade, you’d need 3-4 successful conservative trades (like Example 1) to break even. Discipline > Leverage!

Trade NSE Over BSE to Save on Txn Charges

💡 The Hack:

📊 Example:
Trade: ₹5,00,000 turnover
NSE Txn: ₹5,00,000 × 0.00322% = ₹16.10
BSE Txn: ₹5,00,000 × 0.00375% = ₹18.75
Savings per trade: ₹2.65 (small, but 10 trades = ₹26.50 saved)

Over a year trading 250 days with 10 trades/day = ₹66,250 saved!

✅ Action: Use this calculator to compare NSE vs BSE on your regular trades. Most liquid stocks trade on NSE anyway (RELIANCE, INFY, TCS, BANKNIFTY). No reason to trade BSE unless specific reasons.

Use Monte Carlo to Pre-Filter Bad Setups

💡 The Hack:

📊 Example Decision Tree:
• Win Probability 75%+ → TRADE (high conviction)
• Win Probability 60-74% → TRADE (acceptable risk)
• Win Probability 50-59% → SKIP or reduce size (coin flip)
• Win Probability < 50% → DON'T TRADE (negative expectancy)

Result: Traders following this rule avoid ~30% of their worst trades, which translates to 40-50% improvement in overall profitability.

⚠️ Common Mistake: Traders ignore low win probability and trade anyway because “this time it’s different.” It never is. The calculator doesn’t lie. Trust the math.

Calculate Break-Even Price Before Entry

💡 The Hack:

📊 Real Example:
Buy INFOSYS at ₹1,500 with 5x leverage
Quantity: 50 shares
Run calculator → Net P&L = 0 at Sell Price = ₹1,502.50

Interpretation: Stock must rise ₹2.50 (0.167%) just to break even. If your technical analysis only targets ₹1,505 (0.333%), that’s only 2x your break-even move. Too tight! Look for setup where target is at least 5x the break-even move.

✅ Pro Trader Workflow: Calculate break-even → check if your profit target is ≥5x break-even → check win probability → enter. Skip if any condition fails.

Optimize Leverage for Your Risk Tolerance

💡 The Hack:

📊 Leverage Comparison (Same ₹50K trade, 2% move):

• 1x leverage → Margin: ₹50,000 → ROI: 3.8% → Win Prob: 85%
• 5x leverage → Margin: ₹10,000 → ROI: 19.2% → Win Prob: 72%
• 10x leverage → Margin: ₹5,000 → ROI: 38.4% → Win Prob: 45%

Decision: If you can afford to trade 5x regularly with discipline, that’s the Goldilocks zone—good ROI + reasonable win probability. 10x only if you’re an expert.

⚠️ Key Insight: Most losing traders use 10x leverage thinking bigger is better. They lose faster. Use 3-5x until you’re profitable for 12+ months, THEN consider higher leverage.

Export & Track Your Calculations for Tax & Performance

💡 The Hack:

📊 What to Track:

• Total trades: 150

1️⃣ What is intraday trading?

Intraday trading means buying and selling stocks within the same trading day. The position must be squared off (closed) before 3:20 PM IST. You use MIS (Margin Intraday Square-off) product which offers higher leverage (3x-10x) but mandatory auto-square-off.

2️⃣ What is MIS and how does it differ from delivery?

MIS (Margin Intraday Square-off) is for same-day trading with leverage (3x-10x). Delivery is for overnight holding with 1x leverage (full payment required). MIS offers higher ROI but must be closed before 3:20 PM or broker auto-squares off.

3️⃣ How is gross P&L calculated?

Gross P&L = (Sell Price – Buy Price) × Quantity. Example: Buy RELIANCE at ₹2,500, sell at ₹2,510, quantity 50 = (2,510-2,500) × 50 = ₹500 gross profit. This is BEFORE charges are deducted.

4️⃣ What charges are applied on intraday trades?

Intraday charges: (1) Brokerage (₹20/order), (2) STT 0.025% on sell value, (3) Transaction charge (NSE 0.00322%, BSE 0.00375%), (4) SEBI fee (₹10/crore), (5) Stamp duty 0.003% on buy, (6) GST 18% on brokerage+txn+SEBI, (7) DP charges (typically ₹0 for intraday).

5️⃣ How does leverage amplify profits and losses?

Leverage = Multiple of your actual capital. With 5x leverage, ₹10,000 controls ₹50,000. A 2% price move = ₹1,000 gain/loss. On 5x leverage, ROI = 10% (₹1,000 on ₹10,000 margin). Without leverage, only 2% on ₹50,000 full capital.

6️⃣ What is margin required?

Margin = Trade Value ÷ Leverage. Example: Buy ₹50,000 worth stock at 5x leverage = ₹50,000 ÷ 5 = ₹10,000 margin required. This is the actual cash you need in your account to enter the trade.

7️⃣ What is ROI (Return on Investment)?

ROI = (Net P&L ÷ Margin Required) × 100. Example: If you make ₹500 net profit on ₹10,000 margin, ROI = (500÷10,000)×100 = 5%. ROI shows return ONLY on margin used, not total capital.

8️⃣ NSE or BSE – which is cheaper?

NSE is cheaper: 0.00322% transaction fee vs BSE 0.00375%. For a ₹5,00,000 turnover, NSE saves ₹2.65 per trade. Over 10 trades/day for 250 trading days, NSE saves ~₹66,250 annually!

9️⃣ What is STT and why is it charged?

STT (Securities Transaction Tax) = 0.025% on sell value for intraday equity. It’s a government tax. Example: Sell ₹50,000 = STT ₹12.50. SEBI charges this to discourage excessive speculation and boost market stability.

🔟 What is break-even price?

Break-even = Buy Price + (Total Charges ÷ Quantity). Example: Buy at ₹500, charges ₹50, qty 100 = 500 + (50÷100) = ₹500.50. Stock must rise above ₹500.50 to actually profit. Below this, you lose money.

1️⃣1️⃣ What is Monte Carlo simulation?

Monte Carlo runs 100 random price scenarios (varying ±2% from buy price) and calculates P&L for each. Shows you win probability, not just one outcome. 60%+ win probability means the trade has positive expectancy.

1️⃣2️⃣ How should I choose my leverage?

Beginners: 3x leverage. Intermediate (6-12 months profitable): 5x. Advanced: 7-10x. Never use maximum leverage just because it’s available. Balance: 5x gives 19.2% ROI on 2% move with 72% win prob—better than 10x’s 38.4% with 45% prob.

1️⃣3️⃣ What time must I close my intraday position?

You MUST close before 3:20 PM IST (market close). If not, broker auto-squares off your position. Some brokers square off at 3:15 PM sharp. Check with your broker. Missing this deadline = forced sale + potential slippage losses.

1️⃣4️⃣ Are intraday profits taxed differently?

Intraday profits are “speculative business income” and added to your salary income (slab rate applies). No long-term capital gains benefit. If you make ₹5L intraday profit + ₹10L salary, you pay tax on full ₹15L. Keep records for ITR filing.

1️⃣5️⃣ Can I use this calculator for options or futures?

This calculator is for EQUITY only. Options and futures use different margin models (SPAN, exposure, Greeks). For F&O trades, use broker-specific F&O margin calculators. The logic is fundamentally different.

1️⃣6️⃣ What’s the 2% risk rule and why is it important?

Never risk more than 2% of your total capital on any single trade. Example: ₹10L capital → risk max ₹20K per trade. This rule ensures you survive 50 consecutive losses without wiping out. Missing this = bankruptcy risk.
