Financial Modeling Skill
Overview
I help you build integrated 3-statement financial models that link Income Statement, Balance Sheet, and Cash Flow Statement. These models are essential for valuation, budgeting, and strategic planning.
What I can do:
- Build income statement projections
- Create balance sheet forecasts
- Generate cash flow statements
- Model working capital requirements
- Build debt schedules and interest calculations
- Create scenario analysis (base/bull/bear cases)
What I cannot do:
- Access real-time financial data
- Guarantee projection accuracy
- Provide accounting advice
- Replace professional financial analysis
How to Use Me
Step 1: Provide Historical Data
I need 2-3 years of:
- Income statement (revenue, COGS, operating expenses)
- Balance sheet (assets, liabilities, equity)
- Cash flow statement (optional but helpful)
Step 2: Define Projection Assumptions
Key drivers:
- Revenue growth rate
- Gross margin
- Operating expense ratios
- Capex as % of revenue
- Working capital days (DSO, DIO, DPO)
Step 3: Choose Model Scope
- Basic: Income statement only
- Standard: Income statement + balance sheet
- Full: Complete 3-statement model with cash flow

Key Formulas
Income Statement Drivers
Revenue = Prior Year × (1 + Growth Rate) COGS = Revenue × (1 - Gross Margin %) Gross Profit = Revenue - COGS SG&A = Revenue × SG&A % EBITDA = Gross Profit - SG&A D&A = Prior PP&E × D&A Rate OR Revenue × D&A % EBIT = EBITDA - D&A Interest = Avg Debt × Interest Rate EBT = EBIT - Interest Taxes = EBT × Tax Rate Net Income = EBT - Taxes
Balance Sheet Drivers
Accounts Receivable = Revenue × (DSO / 365) Inventory = COGS × (DIO / 365) Accounts Payable = COGS × (DPO / 365) PP&E = Prior PP&E + Capex - D&A Retained Earnings = Prior RE + Net Income - Dividends Cash = Total Liabilities + Equity - Other Assets (plug)
Cash Flow Statement
Operating Cash Flow: Net Income + D&A (non-cash) - Increase in AR - Increase in Inventory + Increase in AP = Cash from Operations Investing Cash Flow: - Capex = Cash from Investing Financing Cash Flow: + Debt Issuance - Debt Repayment - Dividends = Cash from Financing Net Change in Cash = CFO + CFI + CFF

Tips for Better Results
- Provide clean historical data in a consistent format
- Be specific about growth drivers (volume vs price, organic vs acquisition)
- Specify industry context for appropriate benchmarks
- Ask for scenario analysis to understand range of outcomes
- Request sensitivity tables for key assumptions
Limitations
- Projections are only as good as the assumptions
- Cannot model complex corporate structures
- Does not account for one-time items automatically
- Simplified tax calculations
- Currency assumed constant (no FX modeling)
