# Options Calculator

> An interactive options profit/loss calculator with payoff graphs, multi-leg strategy modeling and Greeks for standard U.S. stock and ETF options.

The calculator produces theoretical model prices from scenario inputs; it does not provide live quotes or execute trades. It models American-style call and put positions with a 100-share contract multiplier. The methodology describes pricing models, units and numerical limitations.

## Common uses

- [Interactive options payoff graphs](https://optionscalculator.io/): Explore profit/loss before and at expiration, switch between stock-price and time-to-expiry views, and compare two points on a curve.
- [Multi-leg options calculator](https://optionscalculator.io/): Build custom call and put positions. View each leg alongside the combined position, calculate entry debit or credit, and examine break-even points and maximum profit/loss at expiration.
- [Options strategy comparison](https://optionscalculator.io/strategies): Explore spreads, straddles, strangles, butterflies and iron condors. Open worked examples in the calculator and adjust the contracts and assumptions.
- [Options Greeks and scenario analysis](https://optionscalculator.io/): Adjust price, volatility and expiration to see how model premiums and position Greeks change. Share a scenario by link.
