Run a DCF Valuation
Calculate the intrinsic value of a business using discounted cash flow analysis with a computed WACC.
Price Bonds and Options
Calculate fair value for bonds using yield-to-maturity and for options using the Black-Scholes model.
Quick answer: Use the Financial Calculator tool through ToolRouter to price bonds and options directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolBond and options pricing requires exact formulae applied to precise inputs. A misplaced decimal in the coupon rate or an incorrect day-count convention produces meaningfully wrong prices. Doing this in a spreadsheet is error-prone; building it from scratch each time is wasteful.
Financial Calculator handles both instruments precisely. For bonds, it calculates price from yield or yield from price, with accrued interest and duration. For options, it applies the Black-Scholes model with inputs for underlying price, strike, volatility, time, and risk-free rate — returning price, delta, gamma, theta, and vega.
Fixed income traders, options market makers, and derivatives students use this to get correct instrument prices and Greeks without building the model themselves.

Claude prices bonds and options and then explains the results in depth. It breaks down what duration means for a bond's price sensitivity, explains each Greek and what it implies for an options position, and helps you interpret the pricing output in the context of the trade you are evaluating.
How to price bonds and options
Once connected (see setup above), use the Financial Calculator tool — the same steps work with Claude, ChatGPT, Microsoft Copilot, OpenClaw, and any MCP client:
- For a bond: provide face value, coupon rate, maturity date, and current yield
- Ask Claude: "Price this bond and show duration and accrued interest"
- For an option: provide underlying price, strike, volatility, time to expiry, and risk-free rate
- Ask Claude: "Price this call option and show all the Greeks"
Example prompt
Try this with the Financial Calculator tool
Price a 5-year government bond with face value £100, 4% coupon, current yield 4.5%. Show the clean price, dirty price, and duration. Then price a call option on the same underlying: strike £98, current price £100, 90 days to expiry, volatility 18%, risk-free rate 5%.
Tips
- Ask Claude to explain what each Greek means for your specific option position — not just the values
- For bonds, ask for both modified duration and Macaulay duration to understand rate sensitivity
- Ask: "If yields rise 50 basis points, what happens to this bond price?" to make duration tangible
