The three statements are not three separate stories — they are a linked set. A figure that changes in one appears somewhere in the others. Understanding these links is what turns a pile of numbers into a picture of the business.
Link 1: profit flows into equity
When a company earns a net profit, it does not simply disappear. Whatever is not paid out to shareholders as dividends is kept in the business as retained earnings, which sits inside equity on the balance sheet.
Closing retained earnings = Opening retained earnings + Net profit − Dividends
Profit left in the business adds to equity; dividends reduce it.
Link 2: cash reconciles
The cash flow statement starts with the cash the company held at the beginning of the period and ends with the cash it holds at the end. The closing figure is the same cash you see as an asset on the balance sheet.
Closing cash = Opening cash + Operating + Investing + Financing cash flows
The three cash flows together explain the whole change in cash.
The three statements are one story
Each statement answers a different question — together they describe the whole business.
Income statement
- Covers a period of time (e.g. a quarter or a year).
- Starts with revenue and subtracts costs step by step.
- Ends at net profit — which flows into retained earnings on the balance sheet.
