Lesson Overview
The income statement, balance sheet, and cash flow statement are not separate reports. They are three views of the same business activity, connected through accounting rules and the movement of cash.
In this lesson, you’ll learn how information flows between the statements — how profits affect equity, how non-cash expenses are handled, and why cash rarely equals net income.
Learning Objectives
- Explain how net income flows into the balance sheet.
- Describe why the cash flow statement starts with net income.
- Track how depreciation, working capital, and capital spending affect cash.
- Understand how financing activities change the balance sheet.
- See the three statements as one connected system.
The Big Picture: One Business, Three Views
- Income Statement: performance over a period
- Balance Sheet: financial position at a point in time
- Cash Flow Statement: movement of cash during the period
Every transaction touches at least two of these statements. The cash flow statement exists specifically to explain the change in cash on the balance sheet.
Connection 1: Income Statement → Balance Sheet
At the end of an accounting period, net income does not disappear. It flows into the balance sheet through retained earnings.
- Net income increases equity
- Net loss reduces equity
- Dividends reduce retained earnings
Equation:
Ending Retained Earnings = Beginning Retained Earnings + Net Income − Dividends
Why Cash ≠ Net Income
The income statement is prepared using accrual accounting, not cash accounting. This means revenue and expenses are recognized when earned or incurred — not when cash changes hands.
As a result, a profitable company can lose cash, and an unprofitable company can temporarily generate cash.
Connection 2: Income Statement → Cash Flow Statement
The cash flow statement begins with net income and then adjusts it to reflect actual cash movement.
Non-Cash Expenses
- Depreciation and amortization reduce net income
- They do not use cash
- They are added back on the cash flow statement
Working Capital Changes
- Accounts receivable ↑ → cash decreases
- Inventory ↑ → cash decreases
- Accounts payable ↑ → cash increases
Connection 3: Cash Flow Statement → Balance Sheet
The cash flow statement explains the change in the cash balance between two balance sheet dates.
- Ending Cash = Beginning Cash + Net Cash Flow
- Net cash flow comes from operating, investing, and financing activities
Investing Activities and the Balance Sheet
Investing cash flows primarily relate to long-term assets.
- Capital expenditures reduce cash and increase fixed assets
- Asset sales increase cash and reduce fixed assets
Depreciation reduces asset values over time but does not affect cash.
Financing Activities and the Balance Sheet
Financing cash flows explain changes in a company’s capital structure.
- Issuing debt increases cash and liabilities
- Repaying debt reduces cash and liabilities
- Issuing equity increases cash and equity
- Dividends reduce cash and retained earnings
The Full Loop (Summary)
- Operations generate profit on the income statement
- Profit flows into retained earnings on the balance sheet
- Cash flow statement reconciles profit to cash
- Cash balance updates on the balance sheet
- Assets = Liabilities + Equity must always hold
Practice: Trace the Flow
- A company reports net income of $100.
- Depreciation is $30.
- Accounts receivable increase by $20.
- Capital expenditures total $50.
