Dollar P&L for the whole position. Pre-expiry cells are model values (constant IV); real marks will differ with volatility and skew.

Common questions

How does this options profit calculator work?: Enter the stock price, implied volatility and days to expiry, then build your position leg by leg (long/short calls, puts, or 100-share stock lots). The tool computes exact profit and loss at expiry, model values before expiry via Black-Scholes, breakevens, max profit, max loss and position greeks — all in your browser.
Is it free? Do I need an account or market data?: Yes — free, no signup, and no data connection: every number comes from your own inputs. Premiums start as Black-Scholes model values; overwrite them with your broker's quotes for exact results.
Which strategies does it support?: Any combination of up to six legs. One-click presets cover long calls and puts, covered calls, cash-secured puts, bull call and bear put spreads, iron condors, straddles, strangles and collars.
How accurate are the pre-expiry values?: At expiry the P&L is exact arithmetic. Before expiry, values use the Black-Scholes model with constant volatility and no dividends — real market marks will differ with volatility changes, skew and early-exercise effects. Treat it as an educational model, not a quote.

Know the company first

Every option is a bet on the business underneath. TENK/calls rates ~4,500 US stocks nightly from their SEC filings — verdict, quality score and the figure behind each call, free.

Educational model, not trade advice. Options involve substantial risk and are not suitable for every investor — read the OCC’s Characteristics and Risks of Standardized Options. Model values use Black-Scholes with your inputs (constant volatility, European exercise, no dividends) and will differ from live market prices.

Research and education only — not financial advice. TENKis not a registered investment adviser or broker-dealer and gives no personalized advice. Every call is impersonal — identical for all users, generated on a schedule from SEC filings plus a delayed/third-party price feed — may be wrong or out of date, and is not a recommendation to buy or sell any security. The operator and an affiliated trading operation may hold or trade the securities TENK rates; see Disclosures. Past performance does not guarantee future results. Do your own research.
