How the three financial statements link together

Almost every accounting question in a banking interview is a test of one idea: how the income statement, cash flow statement and balance sheet connect.

What each statement shows

  • Income statement: revenue, costs and profit over a period. It ends in net income.
  • Balance sheet: what the company owns (assets) and how it's funded (liabilities and equity) at one point in time. Assets always equal liabilities plus equity.
  • Cash flow statement: how cash moved over the period, split into operating, investing and financing activities.

The links

  1. Net income from the income statement is the first line of the cash flow statement.
  2. The cash flow statement adds back non-cash items (like depreciation) and adjusts for balance sheet changes (like stock and debtors) to reach the change in cash.
  3. Ending cash goes onto the balance sheet. Net income also flows into retained earnings, so the balance sheet still balances.

A UK detail worth knowing

From January 2027, IFRS 18 changes how UK and European companies lay out the cash flow statement: it starts from operating profit rather than net income. Interviews still mostly use the net income version, but mentioning the change shows you read real accounts.
