How the options P&L calculator works

The calculator mirrors how an intraday option round trip is settled:

  1. Quantity = lots × lot size. For example, 2 lots of Nifty at 75 units per lot is 150 units.
  2. Gross P&L for a long trade = (exit premium − entry premium) × quantity. For a short trade it is (entry premium − exit premium) × quantity.
  3. Charges are estimated per leg: brokerage on each order, STT on the sell premium, exchange and SEBI charges on premium turnover, stamp duty on the buy side, and 18% GST on brokerage plus transaction charges.
  4. Net P&L = gross P&L − total charges.

Worked example

Buy 1 lot of Nifty 23000 CE at ₹150 and exit at ₹200, lot size 75:

  • Gross P&L = (200 − 150) × 75 = ₹3,750
  • Charges (₹20 brokerage per order) ≈ ₹70–₹80 including all statutory levies
  • Net P&L ≈ ₹3,670, and the breakeven exit premium is about ₹151

Charges look small in percentage terms, but on cheap options they can be 10% or more of the premium — which is why they matter most for far OTM strikes.

Common questions

Is STT charged on both buy and sell?
For equity options, STT is charged on the sell side of the premium (0.1%) at the current rate. The buy side does not attract STT in intraday F&O; instead it attracts stamp duty. Rates are set by the government and can change.
Why is my broker's charge different?
Brokerage plans differ (flat per order vs per lot), and exchange or regulatory rates change over time. The estimate here uses ₹20 per order by default — change the field to match your plan.
Does this work for options I hold to expiry?
This models an intraday round trip. Options settled at expiry (ITM exercised) can attract different STT treatment. For expiry positions, check your broker's settlement charges.
Should I include charges in my targets?
Yes. Serious traders set targets on net P&L, not gross. A small edge can disappear after costs if you trade too frequently or in cheap options.
