收入 (shōu rù) is a noun meaning 'income' — the money a person or organization receives, typically from work, investments, or business activities. It combines two characters: 收 (shōu), meaning 'to receive' or 'to collect', and 入 (rù), meaning 'to enter' or 'to come in'. Together, they literally convey the idea of money 'entering' or 'being received' — emphasizing the inflow of funds. This word is neutral in register and widely used in both spoken and written Chinese, especially in financial, workplace, and personal budgeting contexts.

收入 is commonly modified by measure words like '份' (fèn) or '笔' (bǐ) when counting individual sources ('a source of income', 'a sum of income'), and frequently appears with verbs like '增加' (zēngjiā, 'to increase') or '减少' (jiǎnshǎo, 'to decrease'). It contrasts with 支出 (zhīchū, 'expenditure') — the outflow of money — and is central to discussions about household finances, taxation, salary negotiations, and economic reports.
