How to Run a DCF Valuation with Claude
Run a DCF valuation with Claude and ToolRouter. Compute intrinsic value and WACC interactively in your terminal.
Tool
Claude runs the DCF and then works through the results with you. It explains which assumptions drive the valuation most, calculates the WACC components from your capital structure, and tests alternative scenarios — walking you through the model logic rather than just returning a number.

Steps
Once connected (see setup above), use the Financial Calculator tool:
- Provide your inputs: projected free cash flows, capital structure, cost of equity, and cost of debt
- Ask Claude: "Run a DCF valuation with these inputs and compute the WACC"
- Claude returns enterprise value, per-share value, and WACC breakdown
- Ask: "What happens to the valuation if revenue growth is 10% lower than projected?"
Example Prompt
Try this with Claude using the Financial Calculator tool
Run a DCF valuation for a company with the following: Year 1-5 FCF of £5m, £6m, £7m, £8m, £9m. Terminal growth rate 2.5%. Debt £20m at 5%, equity £80m, equity beta 1.2, risk-free rate 4.5%, market premium 5.5%. Show the enterprise value and a sensitivity table.
Tips
- Ask Claude to calculate WACC separately first so you can sense-check it before running the full model
- Request a sensitivity table across both discount rate and terminal growth rate — these are the two biggest valuation drivers
- Ask which year's cash flow contributes most to the total value to understand model risk concentration
