Use the formula and worked example below to calculate manually.
Overview
The day trade calculator computes the net profit or loss on an intraday trade after accounting for brokerage, STT (Securities Transaction Tax), exchange fees, and GST — giving you the true break-even price.
How to use this calculator
- Enter the buy price, sell price, and quantity.
- Enter your brokerage rate (flat fee or percentage).
- The calculator deducts STT, exchange charges, and GST to show net profit/loss and the actual break-even sell price.
Understanding the inputs & results
Buy price
The price at which you entered the trade.
Sell price
The price at which you exited the trade.
STT (Securities Transaction Tax)
A tax on equity transactions — 0.025% on intraday sell turnover (as of 2024).
Exchange charges
NSE/BSE transaction charges, typically 0.00297% on intraday turnover.
Break-even price
The minimum sell price needed to cover all costs and not lose money.
Net P&L
Gross profit minus all brokerage, taxes, and charges.
The formula
Net P&L on intraday trade
Net P&L = (Sell − Buy) × Qty − Brokerage − STT − Exchange charges − GST
Gross profit = (Sell − Buy) × Quantity. All charges are deducted to arrive at net P&L. Break-even = Buy + (total charges / Quantity).
Worked example
Buy 100 shares at ₹500, sell at ₹510. Brokerage ₹20 flat.
- Gross profit = (510 − 500) × 100 = ₹1,000.
- STT = 0.025% × 510 × 100 = ₹12.75.
- Exchange charges ≈ ₹3. GST ≈ ₹4.30.
- Net profit = 1,000 − 20 − 12.75 − 3 − 4.30 ≈ ₹959.95.
✓ Net profit ≈ ₹960 on a ₹1,000 gross gain after all charges.
