Income statement vs. Cash flow statement

Income statement vs. cash flow statement

Use the income statement to understand reported performance and the cash flow statement to understand why cash changed. Profit and cash differ because not every revenue or expense moves cash in the same period, and not every cash movement affects profit.

Balance sheet vs. income statementThe balance sheet answers what the business owns, owes, and has accumulated at one date. The income statement answers how much the business earned or lost over a span of time. The statements are connected through equity and net income.Revenue vs. cash receivedRevenue describes what the business earned; cash received describes money that moved. They can differ because of accounting method, receivables, customer deposits, sales tax, transfers, loans, and owner funding.Gross profit vs. net profitGross profit measures the amount left after direct costs of sales. Net profit measures what remains after operating expenses and other recognized costs. A business can have strong gross profit but weak net profit because overhead is too high.
