3 Statement Financial Modeling: Step 2

Master integrated financial statement modeling fundamentals

Three Statement Model Foundation

The three statement model integrates the Income Statement, Balance Sheet, and Cash Flow Statement into a single dynamic framework where changes in one statement automatically flow through to the others.

Core Financial Statements Overview

Income Statement

Shows company profitability over a specific period. Records revenues, expenses, and net income that flows to retained earnings.

Balance Sheet

Presents financial position at a point in time. Assets must equal liabilities plus equity, with retained earnings from income statement.

Cash Flow Statement

Tracks actual cash movements through operating, investing, and financing activities. Links net income to cash position changes.

Financial Statement Integration Process

1

Build Income Statement

Start with revenue projections and work down through expenses to calculate net income, which becomes the foundation for other statements.

2

Flow to Balance Sheet

Net income flows to retained earnings, while balance sheet items like depreciation and working capital changes connect back to income statement.

3

Create Cash Flow Links

Begin with net income, adjust for non-cash items, account for working capital changes, and include capital expenditures and financing activities.

4

Verify Integration

Ensure cash flow statement ending cash position matches balance sheet cash, and all three statements balance mathematically.
