What problem does it solve? Building a decision-grade financial model in Excel requires strict discipline: assumptions separated from calculations, statements that balance every period, auditable formulas, and cached values that render correctly. This Skill automates that entire workflow, producing a single formula-driven .xlsx file instead of a fragile hand-built spreadsheet. ## Core Features & Use Cases - Three model recipes: Runnable skeletons for 3-statement models (P&L + Balance Sheet + Cash Flow), DCF valuations (WACC, NPV, terminal value, sensitivity grids), and LBO models (debt schedules, cash sweeps, MOIC/IRR returns). - Three-zone architecture enforcement: Inputs, Calc, and Outputs zones with executable audits that reject hardcoded numbers on calculation sheets and verify balance checks. - Sensitivity and scenario analysis: Two-axis WACC × growth sensitivity grids and scenario switches built as explicit formulas. - Use Case: Ask for a DCF valuation of a company and receive an Excel workbook with an assumptions sheet, 10-year FCF forecast, WACC panel, equity bridge, and a color-coded sensitivity table ready for board review. ## Quick Start Ask the AI to build a 3-statement financial model in Excel with revenue growth, margin, and tax assumptions for the next three years.
