From a closed ledger to four reports
In the last rung you closed the books: you posted every adjusting entry, struck an adjusted trial balance, and swept the temporary accounts into retained earnings. That work was not busywork — it was the rehearsal. The reward is the performance, and the performance is a small set of polished reports called the [[financial-statements|financial statements]]. There are four of them, and together they are how a business finally tells the outside world what happened. This guide is the map of the whole rung: we will not master any one statement here, but we will see how all four lock together so that the detail in the next guides has a place to live.
Here is the cast, in the order they are usually prepared. The [[income-statement|income statement]] asks *how did we do over the period?* — it nets revenue against expense to land on profit. The [[statement-of-retained-earnings|statement of retained earnings]] asks *what did profit do to the owners' accumulated stake?* — it carries that profit forward into equity. The [[balance-sheet|balance sheet]] asks *where do we stand right now?* — a snapshot of everything owned and owed at one instant. And the [[cash-flow-statement|cash flow statement]] asks *where did the actual money go?* — it follows cash, and only cash, in and out of the business.
Profit flows from the income statement into equity
The first link is the one you already half-built when you closed the books. The income statement does its arithmetic — revenue minus expense — and produces a single bottom-line number, [[net-income|net income]] (or, if expenses won, a net loss). That number does not just sit at the foot of the income statement and stop. It steps across to the statement of retained earnings, where it is added to the owners' accumulated profits from all prior years. This is exactly the closing entry you already performed, now wearing its report-day clothes.
Retained earnings, beginning 120,000 + Net income for the year 25,000 <- from the income statement - Dividends declared (8,000) ---------------------------------------- Retained earnings, ending 137,000 -> to the balance sheet
Read that little schedule slowly, because two beginner traps live in it. First, dividends sit *below* net income, not inside it: paying owners is a distribution of profit already earned, never a cost of earning it — confuse the two and your profit will be wrong. Second, the ending [[retained-earnings|retained earnings]] balance is not a wallet of spare cash; it is a running tally of profits kept in the business rather than paid out, and that profit may long ago have been spent on a building or a truck. Retained earnings is a measure of accumulated *claim*, not of cash on hand.
The balance sheet catches what the period statements pour out
Now follow that ending retained-earnings figure one step further. It does not stop on the statement of retained earnings either — it walks straight onto the balance sheet and takes its seat in the equity section. So the chain so far is unbroken: revenue and expense meet on the income statement, their difference (net income) crosses into the statement of retained earnings, and the updated retained-earnings total lands in the equity of the balance sheet. Three statements, one current carrying a single number from end to end.
This is why the balance sheet stays balanced after a profitable year without anyone forcing it. Recall the accounting equation: assets equal liabilities plus equity. When the business earns $25,000, the assets it earned (cash, or a customer's promise to pay) grow by that amount on the left; on the right, retained earnings — and therefore equity — grows by the very same $25,000 that flowed in through net income. Both sides move by the same figure, so the snapshot is still in balance. The income statement is, in a real sense, just a magnifying glass held over one period's change in equity.
Cash flow: the fourth statement, and why profit is not cash
If profit so neatly grows equity, why bother with a fourth statement at all? Because of a fact that surprises every beginner and humbles many a business: profit is not cash. The income statement is built on accrual accounting — it counts revenue when it is earned and expense when it is incurred, regardless of when the money moves. A company can report a healthy net income while its bank balance falls, simply because customers have not paid yet, or because it bought a year's inventory up front. Profit and cash answer two different questions, and a business can die of thirst standing in a river of paper profit.
So the cash flow statement does an entirely different job: it ignores accruals and tracks only money in and money out, then sorts every movement into three buckets — operating activities (the day-to-day trade), investing activities (buying and selling long-term things), and financing activities (raising and repaying capital, paying dividends). Add the three buckets together and you get the net change in cash for the period: how much fuller or emptier the tank got. It is the one statement that strips away every judgement and accrual and asks the bluntest question in business — *did the money actually arrive?*
And here the circle closes. Take the cash balance at the start of the year, add the net change in cash the statement just computed, and you arrive at the ending cash balance — which must equal, to the penny, the cash line sitting at the top of the balance sheet's asset section. That tie is not a happy coincidence; it is a required link between the cash flow statement and the balance sheet. If the cash flow statement's ending cash does not match the balance sheet's cash, the statement is simply wrong. The honest takeaway worth carrying: [[profit-is-not-cash|profit is not cash]], and the fourth statement exists precisely to keep that truth in plain view.
Why no statement stands alone
Step back and look at the whole machine. Net income leaves the income statement and enters retained earnings; retained earnings settles into the balance sheet's equity; the cash flow statement's ending cash ties to the balance sheet's cash; and the cash flow statement usually *begins* from that same net income before unwinding the accruals. The four reports are not four independent documents that happen to be stapled together — they are four views of one closed system, and a number that moves in any one of them is felt in the others. Accountants call this knitting-together the [[articulation-of-statements|articulation of the statements]].
This is why reading a single statement in isolation can mislead you. A glowing income statement means little if the cash flow statement shows money draining away. A fat cash balance on the balance sheet looks reassuring until the cash flow statement reveals it came entirely from new borrowing, not from trading. Each statement covers a blind spot in the others: profitability, position, and liquidity are three different things, and you need all three lenses to see the business honestly. That is the discipline this rung is here to build.
One last piece completes the set, and the next guides will pick it up: the numbers alone never speak for themselves. Behind the four statements stand the notes — the disclosures that say which methods were chosen, what the round figures contain, and what risks loom off to the side. With the map now in hand, you are ready to walk into each statement one at a time, starting with the balance sheet, and read it knowing exactly where its numbers come from and where they go.
