Test a financial model's logic, assumptions, and outputs. Spreadsheet app: [SPREADSHEET_APP]. Model purpose and period: [PURPOSE_AND_PERIOD]. Key assumptions: [ASSUMPTIONS]. Outputs: [OUTPUTS]. Formulas or structure I can share: [MODEL_STRUCTURE]. Tables: 1. Structure checks: Check | How to test | Result (pass, fail, unknown) | Note. Cover separation of inputs, calculations, and outputs; consistent formulas across rows; no hardcodes in formulas; balance and cash checks; circular references; units and periods. 2. Assumption review: Assumption | Value | Evidence | Reasonableness (low, medium, high concern) | Sensitivity (what happens to the output if it moves 10 percent). 3. Output reasonableness: Metric | Value | Reality check (growth versus history, margins versus similar businesses, cash needs versus funding) | Concern. 4. Stress tests: three scenarios with the formulas to run them. 5. Errors found and fixes. State assumptions, do not invent benchmarks (say where I should look them up), and remind me that models are estimates. Have an accountant or financial adviser who knows [JURISDICTION] review any model used for lending, tax, or investment decisions.
