What is an options P&L calculator?
Options profit and loss at expiry depends on how far spot settles from the strike, minus premium paid or plus premium received. Long calls gain when spot rises above strike; long puts gain when spot falls below strike.
This tool plots that payoff for NSE-style lot sizes so you can sanity-check risk before placing orders in your broker terminal.
How to use this tool
Choose call or put and long or short. Enter strike, premium per share, lot size, and number of lots.
Read breakeven and max loss (when finite) from the summary cards; use the chart for scenarios between the spot range shown.
Figures ignore STT, charges, and early assignment—only expiry intrinsic value.
