CallPutHub

What it is

CallPutHub is a free options-analytics toolkit that includes a full options trade analyzer, dozens of calculators for calls, puts, and wheel strategies, a catalog of 58 strategy presets, and a plain-English learning library. It runs without requiring an account, with all positions staying in your browser for privacy.

The tool helps traders understand options trades by showing exact numbers at expiration and clearly labeled estimates before expiration. It uses Black-Scholes-Merton calculations with dividend yield, displays volatility sources for each leg, and provides scenario matrices showing profit and loss across price and time variations.

Key features include the ability to build custom single- or multi-leg positions, connect optional MarketData.app tokens for option chains, and access 20+ focused calculators for specific strategies. The platform emphasizes transparency about which numbers are exact arithmetic, which are model estimates, and which come from user input.

Questions from the bench

What is CallPutHub?

CallPutHub is a free online options trade analyzer where you describe a position and it shows net debit or credit, maximum profit and loss, breakevens, payoff at expiration, and estimated profit and loss across price, time, and volatility scenarios.

Is it really free and do I need an account?

The analyzer, calculators, and learning library are completely free and work without an account. An account only adds extras like saving trades across devices; the analyzer itself saves positions in your browser either way.

How accurate are the numbers before expiration?

Numbers at expiration are exact arithmetic from your inputs. Values before expiration are theoretical estimates from a Black-Scholes model using your pricing assumptions, and the interface clearly labels them as estimates. Each leg's volatility source is shown, never silently assumed.

Does CallPutHub give investment advice?

No. The tool states the mathematical outcomes of the inputs you provide; it does not recommend trades and knows nothing about your financial situation. Options involve substantial risk, so please read the risk disclaimer and verify everything independently before trading.

What happens to my positions?

By default they stay in your browser's local storage. When you share a position, it is encoded in the link itself with no server copy. An optional MarketData.app token lives only in the current tab's memory.
