How the Income Statement, Balance Sheet, and Cash Flow Statement Connect
Learn to connect the three financial statements through net income, cash, and working capital. Credit sales and capital expenditure examples explain why profit differs from cash flow.
The income statement shows performance over a period, the balance sheet shows balances on a particular date, and the cash flow statement shows changes in cash over a period. Connecting net income, cash, and movements in receivables and inventory across the three statements reveals where earnings growth has ended up. A complete set of financial statements also includes a statement of changes in equity, notes, and other required components.
Distinguish when revenue is earned from when cash is received
If goods are delivered and revenue is recognized but payment is due later, the income statement records revenue and the balance sheet records a trade receivable. In the following period, collecting the cash reduces receivables and increases cash, without recognizing the same revenue again. A timing difference between revenue growth and cash inflows is therefore not, by itself, an error. Recording closing receivables and the terms for subsequent collection alongside the current period's revenue increase makes this difference easier to track.
Capital expenditure affects cash and expenses at different speeds
Paying for equipment reduces cash when payment is made, but the entire purchase price does not necessarily become an expense on that day's income statement. If the equipment is recognized as an asset and depreciated as it is used, investing cash outflows and income statement expenses will differ in amount. Conversely, adding depreciation back when calculating operating cash flow does not recover the money already spent on equipment. Avoid counting that add-back a second time as an increase in cash-generating capacity.
Start by reconciling balances that should agree
Opening cash, adjusted for the net change in cash and separate reconciling items such as exchange rate effects, should reconcile to closing cash. Net income, together with dividends, capital transactions, other comprehensive income, and other movements, explains changes in equity in the statement of changes in equity. Mixing consolidated and separate statements, or arbitrarily adding short-term financial products to cash and cash equivalents, will disrupt the reconciliation. When figures do not agree, first check that the statements cover the same reporting scope, currency, and reporting date before concluding that something is wrong with the business. Connecting the statements means identifying and recording the disclosed items that explain differences, rather than forcing figures to match.
Worked example
Hypothetical example: A company starts with KRW 1 million in cash and sells goods already in inventory, costing KRW 600,000, on credit for KRW 1 million. Assume the inventory cost and other expenses have already been paid. The sale generates a profit of KRW 400,000, but the cash inflow at the time of sale is KRW 0 and receivables increase by KRW 1 million. Collecting KRW 1 million in the following period brings cash to KRW 2 million and clears the receivable. Under the simplifying assumption of no taxes or other transactions, this shows that profit can be recorded in a different period from the related cash receipt.
What to check
- Check that all three statements use the same consolidated or separate basis.
- Reconcile closing cash on the cash flow statement to the balance sheet.
- Examine whether increased net income has accumulated in receivables, inventory, or cash.
- Distinguish dividends from share issues in changes in equity.
