How to Price Bonds and Options with ChatGPT
Price bonds and options with ChatGPT and ToolRouter. Instrument pricing with plain-language interpretation.
Tool
ChatGPT prices bonds and options and explains the outputs in accessible terms. It translates duration into plain-language rate risk, describes what a delta of 0.65 means for your portfolio position, and walks through how implied volatility affects option pricing — making derivatives pricing understandable without a quant background.

Steps
Once connected (see setup above), use the Financial Calculator tool:
- Provide bond or option parameters
- Ask: "Price this bond / option and explain the key outputs"
- ChatGPT returns the price with a plain-language explanation of the result
- Ask follow-up questions about how price changes with market moves
Example Prompt
Try this with ChatGPT using the Financial Calculator tool
Price an at-the-money call option: underlying $150, strike $150, 60 days to expiry, implied volatility 22%, risk-free rate 5%. Return the option price and Greeks. Explain what the delta and theta mean for holding this option.
Tips
- Ask ChatGPT to explain the P&L profile of an option across different expiry scenarios
- Request a comparison between implied and historical volatility if you have both — it reveals whether options are expensive or cheap
- For bonds, ask ChatGPT to put the yield-to-maturity in context relative to current market rates
