Run a DCF Valuation

Calculate the intrinsic value of a business using discounted cash flow analysis with a computed WACC.

Quick answer: Use the Financial Calculator tool through ToolRouter to run a dcf valuation directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.

Financial Calculator

Building a DCF model from scratch in a spreadsheet takes hours of formula work, and errors in the discount rate or terminal value calculations can make the entire output meaningless. Most analysts either rely on pre-built templates they do not fully understand, or pay for platforms that lock key assumptions behind interfaces rather than exposing the underlying maths.

Financial Calculator runs a DCF valuation from your inputs — projected cash flows, growth rates, and capital structure — and computes WACC automatically from debt and equity costs. The output includes the enterprise value, per-share value at your stated share count, and a sensitivity table showing how the result changes across discount rate and terminal growth rate combinations.

Investment analysts, founders raising capital, and M&A advisors use this to run rigorous valuations in minutes rather than building models from scratch.

How to run a dcf valuation with Claude, ChatGPT, Microsoft Copilot, and OpenClaw

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.

How to run a dcf valuation with Claude

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 for Claude

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 for Claude

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

ChatGPT runs the DCF valuation and explains the result in terms that make sense to a non-technical audience. It presents enterprise value alongside the key assumptions driving it, explains what the sensitivity table means for investment risk, and helps you understand which inputs are most important to get right.

How to run a dcf valuation with ChatGPT

Once connected (see setup above), use the Financial Calculator tool:

Provide your cash flow projections, capital structure, and cost assumptions
Ask: "Run a DCF valuation and compute WACC from these inputs"
ChatGPT returns the valuation with a plain-language interpretation of the result
Ask: "How sensitive is this valuation to changes in the discount rate?"

Example prompt for ChatGPT

Try this with ChatGPT using the Financial Calculator tool

I need to value a company with projected FCF of $3m, $4m, $5m, $6m, $7m over five years, a terminal growth rate of 3%, and a WACC of approximately 9%. Run the DCF and explain the result in plain language.

Tips for ChatGPT

Ask ChatGPT to describe the valuation range rather than a single point estimate — valuations are inherently uncertain
Request a comparison against public market multiples to triangulate your DCF result
Ask which assumptions need to hold true for the valuation to be defensible

Copilot runs DCF calculations and returns structured results that slot directly into financial model codebases or analysis tools. Generate valuation data structures, sensitivity tables as arrays, and WACC calculation breakdowns — building your financial modelling infrastructure with real computed outputs.

How to run a dcf valuation with Copilot

Once connected (see setup above), use the Financial Calculator tool:

In Copilot Chat: "Run a DCF valuation with these cash flows and capital structure inputs"
Copilot returns enterprise value, per-share value, and WACC as structured data
Ask: "Generate a TypeScript function that runs this DCF calculation"

Example prompt for Copilot

Try this with Copilot using the Financial Calculator tool

Run a DCF valuation with FCF of $2m, $3m, $4m, $5m, $6m, terminal growth 2%, WACC 10%. Return the enterprise value, sensitivity matrix, and WACC components as JSON I can use in my valuation model.

Tips for Copilot

Ask for the sensitivity matrix as a 2D array — it slots into charting libraries directly
Use the WACC breakdown to generate a capital structure display component
Copilot can generate a DCF class or function from the returned calculation logic

OpenClaw runs DCF valuations at scale. Apply consistent discount rate assumptions across a portfolio of companies, generate comparative valuation tables, and run scenario analyses across multiple sets of cash flow projections — systematic valuation without spreadsheet overhead.

How to run a dcf valuation with OpenClaw

Once connected (see setup above), use the Financial Calculator tool:

Provide cash flow projections and capital structure for each company
Ask: "Run a DCF valuation for each company using consistent WACC assumptions"
OpenClaw returns valuations with WACC and enterprise value for each
Ask: "Show the valuation range across all companies in a comparison table"

Example prompt for OpenClaw

Try this with OpenClaw using the Financial Calculator tool

Run DCF valuations for three companies using the same WACC of 9% and terminal growth rate of 2.5%. Cash flows provided separately for each. Return enterprise values and per-share values in a comparison table.

Tips for OpenClaw

Lock WACC assumptions across a portfolio run to ensure comparability
Run the same model with different terminal growth rates to understand value sensitivity across the portfolio
Use batch valuation outputs to build ranking tables for investment committee presentations
