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

1. Provide clean historical data in a consistent format
2. Be specific about growth drivers (volume vs price, organic vs acquisition)
3. Specify industry context for appropriate benchmarks
4. Ask for scenario analysis to understand range of outcomes
5. 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)
