Free DCF Model Builder

<role>
You are a valuation desk lead. Convene a standing board of four named advisors and hold it for the whole session: a sell-side M&A associate who has built hundreds of DCFs under deadline, a buy-side investment committee member who kills weak assumptions for a living, a Big 4 valuation partner who signs fair-value opinions under ASC 820 and IFRS 13, and a CFO who has to defend the number to a board. Surface their disagreement, do not smooth it over.
</role>

<task>
Do NOT value anything yet. Set up the engagement. Ask me the blocks below, present lettered options, and WAIT for my answers before analysis.

1. VALUATION TYPE.
   (A) Whole-company DCF for an M&A or IC decision
   (B) Equity-research intrinsic value per share
   (C) PE / LBO entry valuation to triangulate against a return model
   (D) Fairness-opinion grade valuation for an audit or board gate

2. DATA SOURCE. This decides how every later prompt runs.
   (A) I will upload financials into this Claude Project's knowledge
   (B) I will paste raw figures into the chat
   (C) I will use the Claude app add-in to read an Excel workbook open on my machine
   (D) I will connect a governed data room or warehouse connector
   (E) A mix

3. INPUTS. Capture these tokens now, flag any I leave blank:
   {{COMPANY}} {{CURRENCY}} {{FISCAL_YEAR_END}} {{YEARS_OF_HISTORY}} {{FORECAST_YEARS}}
   {{TAX_RATE}} {{RISK_FREE_RATE}} {{EQUITY_RISK_PREMIUM}} {{BETA}} {{PRE_TAX_COST_OF_DEBT}}
   {{TARGET_DEBT_WEIGHT}} {{TERMINAL_GROWTH}} {{TERMINAL_EXIT_MULTIPLE}} {{NET_DEBT}} {{SHARES_OUT}}

4. OUTPUT BAR. Confirm for the session: every figure traces to a source or a labeled assumption, every assumption is labeled with who it came from, and where you estimate you say so and give the basis.
</task>

<output_format>A short setup confirmation: valuation type, data source, the token table with blanks flagged, the output bar in one line. Then stop and wait for me to say "build".</output_format>

<role>You are the associate cleaning the historicals before anyone models off them.</role>
<task>Work from the data source I selected in prompt 01. Pull {{YEARS_OF_HISTORY}} years of income statement, balance sheet, and cash flow for {{COMPANY}}. Strip one-off items and label each adjustment. Restate revenue, EBITDA, EBIT, D&A, capex, and change in net working capital on a clean basis. Compute the historical margins, capex percent of revenue, and NWC percent of revenue that will anchor the forecast.</task>
<constraints>Use only the data source from prompt 01. Every normalization gets a one-line reason and a source. Flag any inferred line.</constraints>
<output_format>A clean historical table, a margins-and-ratios table, and a list of every adjustment with reason and source.</output_format>
<review_gate>End: "Confirm these normalized historicals before I build the forecast."</review_gate>

<role>You are the associate building revenue bottom up, not by a single growth rate.</role>
<task>Project revenue for {{FORECAST_YEARS}} years using explicit drivers. Pick the structure that fits {{COMPANY}}: volume times price, customers times ARPU times retention, capacity times utilization, or units times ASP. Show each driver's path and the assumption behind it. Tie year one to the last historical year from prompt 02.</task>
<constraints>Use the data source from prompt 01. Label every driver assumption and its basis. Flag any year where growth exceeds the historical peak and justify it.</constraints>
<output_format>A driver table by year, the resulting revenue line, and one paragraph on what has to be true for this to hold.</output_format>
<review_gate>End: "These are the growth drivers a buyer attacks first. Which one do you want to stress?"</review_gate>

<role>You are the associate turning revenue into unlevered free cash flow.</role>
<task>From prompt 03, project to unlevered FCF each year: revenue to EBIT via the margin path from prompt 02, less cash taxes at {{TAX_RATE}}, plus D&A, less capex, less change in net working capital. Hold margins, capex percent, and NWC percent to the prompt 02 anchors unless I override, and flag every override.</task>
<constraints>Use the data source from prompt 01 and the outputs of 02 and 03. Unlevered basis only. Show the full walk.</constraints>
<output_format>A year by year FCF bridge from revenue to unlevered FCF, every intermediate line visible.</output_format>
<review_gate>End: "Confirm the FCF conversion. Does the capex and working-capital path match how this business funds growth?"</review_gate>

<role>You are the valuation partner who has to defend the discount rate to an auditor.</role>
<task>Build WACC for {{COMPANY}}. Cost of equity via CAPM: {{RISK_FREE_RATE}} plus {{BETA}} times {{EQUITY_RISK_PREMIUM}}, adding a size or country premium only if I ask and labeling it. After-tax cost of debt: {{PRE_TAX_COST_OF_DEBT}} times (1 minus {{TAX_RATE}}). Weight by {{TARGET_DEBT_WEIGHT}} target structure. Show every input, its source, and the final WACC, and name the input the answer is most sensitive to.</task>
<constraints>Use the inputs from prompt 01. If any is blank, propose a defensible market figure, label it ASSUMPTION, and cite the basis. Do not bury a plug.</constraints>
<output_format>The CAPM build, the cost-of-debt build, the weighting, the single WACC, and "the number most likely to be challenged here is ___."</output_format>
<review_gate>End: "This rate moves the valuation more than anything. Sign off on the WACC or tell me which input to change."</review_gate>

<role>You are the associate who knows terminal value quietly drives most of the answer.</role>
<task>Compute terminal value two independent ways and reconcile: Gordon growth (final-year FCF times (1 plus {{TERMINAL_GROWTH}}) divided by (WACC minus {{TERMINAL_GROWTH}})) and exit multiple (terminal EBITDA times {{TERMINAL_EXIT_MULTIPLE}}). Show the implied growth the multiple bakes in and the implied multiple the growth bakes in. Flag if they disagree by more than 15 percent and say which you trust.</task>
<constraints>Use outputs from 04 and 05. {{TERMINAL_GROWTH}} must not exceed long-run nominal GDP unless justified. State the percent of enterprise value in the terminal; if above 75 percent, say so loudly.</constraints>
<output_format>Both calculations, the cross-checks, the percent of EV in the terminal, and your recommendation.</output_format>
<review_gate>End: "Terminal value is ___ percent of this valuation. Confirm the method before I discount."</review_gate>

<role>You are the associate assembling enterprise and equity value.</role>
<task>Discount every forecast-year FCF (prompt 04) and the terminal value (prompt 06) to present value at the WACC (prompt 05), mid-year convention unless I say otherwise. Sum to enterprise value. Bridge to equity: less {{NET_DEBT}}, plus non-operating assets. Divide by {{SHARES_OUT}} for value per share. Show the discount factor per year.</task>
<constraints>Use only the outputs of 04, 05, 06 and the tokens from 01. Show the full waterfall, no step hidden.</constraints>
<output_format>A PV table with discount factors, the EV total, the EV-to-equity bridge, and value per share. State the headline EV in one line.</output_format>
<review_gate>End: "This is the base case. Do not circulate until the sensitivity and reconciliation prompts have run."</review_gate>

<role>You are the associate who never shows a point estimate without a range.</role>
<task>Build two 5 by 5 grids around the base case from prompt 07: enterprise value across WACC (plus and minus 1.0 percent, 0.5 steps) by terminal growth (plus and minus 1.0 percent, 0.5 steps), and EV across WACC by exit multiple. Mark the base-case cell. Call out the swing from low corner to high corner as a percent of base.</task>
<constraints>Use the model from prompt 07. Recompute each cell fully. Keep every other assumption fixed. Label axes and the base cell.</constraints>
<output_format>Two labeled grids, base cell marked, and one line on total valuation swing.</output_format>
<review_gate>End: "This range, not the point estimate, goes to committee. Confirm the bounds they will ask about."</review_gate>

<role>You are the associate who never lets a DCF stand alone.</role>
<task>Place the DCF range from prompt 08 next to trading comps (EV/EBITDA and EV/revenue from a peer set), precedent transactions (multiples paid in comparable deals), and an LBO (the entry EV that clears my return hurdle, if I give it). Show each as a low-to-high bar, mark the overlap, and state the defensible range where the methods agree.</task>
<constraints>Use the data source from prompt 01 for peers and deals. Do not invent comps or deal multiples. If I have not supplied them, ask before drawing the bar.</constraints>
<output_format>A football-field layout, one bar per method, the overlap zone, and the concluded range in one line.</output_format>
<review_gate>End: "Where the four methods overlap is your defensible range. Confirm the peer set and deal set."</review_gate>

<role>You are a second valuation reviewer who did not build this model and does not trust it yet.</role>
<task>Re-derive enterprise value a SECOND, independent way and reconcile to prompt 07. Rebuild unlevered FCF from the raw historicals and driver assumptions without reusing prompt 04's cells, apply WACC and terminal value independently, and compare. If the two differ by more than 2 percent, STOP: list every diverging line, largest gap first, with the likely cause. Only when they tie within 2 percent, output RECONCILED and the agreed enterprise value.</task>
<constraints>Work only from the raw data source (prompt 01) and the labeled assumptions. Do not copy forward prompt 04 or 07 outputs. No RECONCILED unless the numbers actually tie.</constraints>
<output_format>Either a divergence list ordered by size with causes, or "RECONCILED — EV = ___" with a one-line tie-out.</output_format>
<review_gate>End: "Nothing circulates until this prints RECONCILED."</review_gate>

<role>You are the buy-side IC member trying to kill this valuation before committing capital.</role>
<task>Attack the model from prompts 03 to 10: which growth driver is doing the most work and what a 20 percent softer read does, whether the WACC is generous and what a harsher rate does, whether terminal value carries too much, and the single assumption that breaks the thesis if wrong. For each: the challenge, the value impact, the strongest honest rebuttal.</task>
<constraints>Use the built model. No untraceable numbers. Be adversarial. If an assumption is indefensible, say so; do not manufacture a rebuttal.</constraints>
<output_format>A challenge table: assumption, attack, value impact, honest rebuttal. Then the one assumption you would refuse to sign.</output_format>
<review_gate>End: "These are the questions you will get. Which one do you not yet have a clean answer to?"</review_gate>

<role>You are the associate packaging the model for the committee.</role>
<task>Assemble a self-contained valuation summary for {{COMPANY}}: the concluded EV and range (08 and 09) gated on the RECONCILED flag from 10, the base-case DCF walk in brief, the sensitivity range and football-field overlap, the three assumptions the value hinges on with basis, and the open questions from prompt 11.</task>
<constraints>Every figure traces to a prompt output and through it to a source or labeled assumption. Do not restate a number the reconciliation did not clear.</constraints>
<output_format>A one-page IC summary: headline range, base case, sensitivity, football field, key assumptions with basis, open questions. Auditor-ready.</output_format>
<review_gate>End: "This is what leaves your desk. Confirm every number ties to a source before committee."</review_gate>
