How the Statements Connect
How profit flows from the income statement into the balance sheet, how the cash flow statement explains the change in cash, and an explorer where you make transactions and watch all three statements change.
The short version
The three statements are one connected system. Net income flows into retained earnings on the balance sheet, after dividends, and starts the cash flow statement. The cash flow statement explains exactly how the balance sheet's cash changed. Spending on equipment adds to property and equipment, and depreciation wears it down. Changes in receivables, inventory, and bills link the balance sheet to operating cash flow. Every transaction touches at least two lines, which is why the balance sheet always balances.
By the end of this lesson, you'll be able to
- Trace the main links between the three statements using STU Corp's numbers
- Predict how a transaction affects each statement
- Explain why the balance sheet still balances after every transaction
Why this matters
The last three lessons took the statements one at a time. In reality they're one system, and the links between them are where a lot of understanding happens. Knowing them lets you check that a company's numbers fit together, work out what a piece of news will do to each statement, and spot when something doesn't add up. The SEC's guide makes the same point: no single statement tells the complete story, but together they're very powerful.1
The links, with STU Corp's numbers
| Link | How it works | STU Corp |
|---|---|---|
| Net income to retained earnings | Profit is added to retained earnings, and dividends are taken out | 86 + 58 − 14 = 130 |
| Net income to cash flow | The cash flow statement starts from net income | 58 on both statements |
| Change in cash to the balance sheet | The cash flow statement's bottom line explains the change in cash | 40 + 20 = 60 |
| Equipment | Spending adds to property and equipment; depreciation wears it down | 165 + 40 − 25 = 180 |
| Receivables and inventory | Increases on the balance sheet reduce operating cash flow | Receivables 44 to 50, shown as (6) |
| Bills and prepayments | Increases in payables, accruals, and deferred revenue add to operating cash flow | Payables 27 to 30, shown as +3 |
| Debt | Borrowing and repaying appear in financing activities | 100 to 90, shown as (10) |
| Stock-based pay | Adds to paid-in capital, and is added back in operating cash flow because no cash was paid | 55 + 5 = 60 |
