Options are priced on premium, and ATS charges a simple ₹10 brokerage per lot. STT applies at 0.05% on the sell-side premium, and exchange transaction charges are 0.053% of the premium turnover — these usually dominate options costs.
Enter your buy and sell premium, the number of lots and your contract lot size. The calculator totals brokerage, STT, exchange charges, 18% GST, the SEBI fee and stamp duty, then shows net P&L and breakeven on the premium.
STT on options is 0.05% and is charged on the sell side, calculated on the option premium (not the strike or contract value).
If an in-the-money option is exercised at expiry, STT is charged at 0.125% on the entire contract value, calculated as 0.125% × (strike price + premium) × quantity.
Enter the number of lots and your contract’s lot size (e.g. 75 for Nifty, 35 for Bank Nifty). The calculator uses lots × lot size to value the premium and ₹10 × lots for brokerage.
Exchange transaction charges on options are 0.053% of the premium turnover — higher than other segments — and along with STT make up most of the cost on small premiums.
The calculator divides total charges by your contract quantity to show the per-unit premium move needed to cover costs before you profit.
