Profit and loss for stocks and options. Set your entry, exit, and size. We'll do the math, including the contract multiplier for options.
Educational only. Not financial or trading advice. Result is gross P/L only — does not account for commissions, fees, or assignment costs on options.
For a long stock trade: (Exit − Entry) × Shares. For a short, the sign flips. For options, multiply by the contract multiplier — typically 100 for US equity options, since one option contract represents 100 shares.
The percentage return shown here is calculated against the entry notional (entry × shares × multiplier). That's the standard "return on capital deployed" framing. Some traders prefer to compute return against margin or buying-power impact, which can differ significantly for shorts and options. This calculator uses notional, which is the right reference for cash-account stock trades.
The contract multiplier is what makes options leverage so deceiving. A $1 move in a $100 stock is 1%. A $1 move in a $5 call option is 20%. Same dollar move, very different P&L footprint, very different downside if you size by share count instead of by dollar risk.
This is why position size — covered in our position size calculator — should always be computed in dollars-at-risk, not contracts or shares. Whether you're holding 1 contract or 100 shares, the question that matters is: how many dollars are at risk if your stop hits.
Your P/L tells you what happened. Kyra Trading tells you why. Are your wins on planned setups and your losses on impulsive ones? Do your winning days come after restful ones? Your trade history has the answers. Kyra runs the math.
